A cold front moved across the State of Alabama during the morning hours of February 24th, producing a line of storms along the front. In the southeast portion of central Alabama, breaks in cloud cover after the sun had risen, allowed for the atmosphere to destabilize out ahead of the front. This caused the line of storms to intensify, creating isolated severe thunderstorms in portions of the southeast. Sporadic tree damage and hail of up to 1 inch was reported in several counties.

A 24 hour storm total of 3.40 inches was measured at the Choctawhatchee river gauge near Geneva at Highway 52. The department of highways also reported about 2 to 3 inches of water on Magnolia Avenue near the Walmart and over North Merritt around Geneva. A relatively strong area of low pressure moved through the region during the evening of February 18th and into the overnight hours. Widespread convection with some severe storms and areas of heavy rain accompanied this low pressure system. Convection was aided by very strong wind shear and strong winds just above the surface (around 40-45 knots at 1500-2000 ft AGL). Although instability was minimal, it was still sufficient for some storms to produce severe wind gusts at the surface. In addition, some training of storms occurred, and heavy rainfall amounts along with some minor street flooding resulted.

A cold air mass was gradually retreating from Arkansas on the 13th, but precipitation moved in from the west before the cold air could exit. In most parts of Arkansas, precipitation began as snow. Then, as warmer air moved in during the day, the snow changed to a mixture of sleet and freezing rain. This occurred during the morning in southern and central sections, and during the afternoon in the north. Finally, the wintry mix changed over to rain as warmer air continued to invade the state. This changeover occurred during the morning in the south, around midday in central sections, and during the afternoon or early evening in the north. Snowfall totals over the southern half of the state were well less than an inch. Over the northern half, most snow accumulations were in the 1 to 3 inch range. However, totals to 4 inches were reported in the higher elevations of Newton County south of Jasper, and in northern Baxter County. Freezing rain amounts ranged from a trace to around .10 inch.

A shortwave trough rapidly traversed east across Oklahoma, Arkansas, and extreme Northeast Texas on February 1st, just ahead of a weak cold front that extended from North Texas, into Southeast Oklahoma and Western Arkansas. The air mass south of the front over Northeast Texas, Southwest Arkansas, and extreme Northern Louisiana destabilized sufficiently as temperatures warmed well into the 70s, within a very moist air mass in place. Cold temperatures and strong instability aloft ahead of this shortwave trough resulted in scattered showers and thunderstorms developing over the region, some of which produced marginally severe to at times, severe hail. These storms exited the region during the late afternoon hours, although additional widely scattered thunderstorms redeveloped during the mid-evening hours over Northwest and Northcentral Louisiana, and again produced a couple of reports of marginally severe hail in and near Monroe, LA. These storms diminished during the late evening, as they moved away from the better forcing near the front as it drifted into extreme Northern Louisiana and Deep East Texas.

An upper-level ridge built into the state behind the trough. With a stable airmass in place, a stratus layer formed over the San Joaquin Valley on February 2nd. A dry northwest flow set up over California, with the central California interior between the departing trough to the east and the ridge to the west. This flow helped dissipate the stratus as the day progressed, with the last vestiges of the stratus lingering over the east side of the San Joaquin Valley and the adjacent foothills. The ridge remained over California through February 6th, and then it gave way to an approaching upper-level trough. Patchy fog developed over Merced and Madera Counties during the morning of the 3rd; otherwise mostly clear skies prevailed across the region. Overnight temperatures fell into the 30s under the clear skies, but highs in the central and southern San Joaquin Valley warmed into the mid 60s to mid 70s each day from the 3rd through the 5th. The upper-level trough moved into the central California interior on February 6th. Temperatures over the northern parts of the region cooled, but the south end of the San Joaquin Valley warmed into the mid 70s in strong pre-frontal warming. Strong southeast winds funneled through the passes of the Tehachapi Mountains into the far south end of the Valley, spreading as far north as Bakersfield. Winds gusted to 73 mph at Grapevine Peak on the 6th, and to 45 mph at Meadows Field. A dust storm was created near Lamont by the gusty winds with near-zero visibility. Gusts between 35-45 mph continued over the central and southern San Joaquin Valley continued on February 7th, and sustained wind speeds of 53 mph near Pine Mountain Club in the Tehachapi Mountains. On the afternoon of the 6th, strong winds in the Bakersfield area caused blowing dust. Winds estimated around 35 mph at around 545 pm caused blowing dust and a school bus and big rig collided at Fairfax Road and Panorama Boulevard in Bakersfield due to blowing dust. On the morning of the 7th, strong winds knocked down power poles in both the Fresno and Bakersfield areas. Clouds associated with the trough spread over the San Joaquin Valley on the 7th and kept night-time temperatures mild. Both Bakersfield and Fresno set record high minimum temperatures for the date of 53 degrees, with the low at Meadows Field occurring only 25 minutes before midnight.

February 9th saw an upper-level ridge over California. The ridge continued the above-normal temperatures over the region, with Bakersfield setting a record high for the 9th of 77 degrees, and Fresno tied its record high of 71. The above-normal temperatures continued on the 10th, with Bakersfield and Fresno coming just short of their record highs. This ridge was short-lived, as a series of upper-level troughs flattened the ridge beginning on February 11th, and brought colder weather to the region. The first trough brought a few showers to the central California interior around sunrise, and showers continued to develop through the day. In addition to the showers, clouds associated with the trough kept minimum temperatures well above normal, with both Bakersfield and Fresno having lows on the 11th in the lower 50s; neither city set a record. As the first trough exited the region during the evening of February 11th, gusty winds developed over the Kern County mountains and desert. Gusts to 45 mph were reported behind the cold front. The highway patrol reported Highway 58 was closed due to gusty winds. In the San Joaquin Valley, it was the lack of wind that produced a stable airmass over the Valley floor. Patchy fog developed shortly before sunrise on the 12th, with a few spots reporting visibilities of less than a quarter mile. The second trough brought up to a foot of snow to the Southern Sierra Nevada on February 13th. Winds gusted between 45-55 mph over the Kern County mountain and desert areas during the afternoon and evening of the 13th, and a mid-day shower dropped quarter-inch hail on parts of Bakersfield. A third trough, on February 15th, brought gusty winds to the west side of the San Joaquin Valley, with gusts to 40 mph reported through much of the morning. Eight inches of snow fell near Fish Camp, and 2 inches of snow were reported at Coarsegold. Highway 41 into the Southern Sierra Nevada was closed at Oakhurst due to snow. The CHP escorted traffic over the I-5 Grapevine in Kern County and Tehachapi piled up 8 inches of snowfall. Behind this final trough, cold air settled into the San Joaquin Valley. An upper-level ridge built into the state, bringing mostly clear skies and light winds. Radiational cooling resulted in late season frosts over the region during the early morning of February 16th.

Behind this final trough, cold air settled into the San Joaquin Valley. An upper-level ridge built into the state, bringing mostly clear skies and light winds. Radiational cooling resulted in late season frosts over the region during the early morning of February 16th. An upper-level trough moved through the central California interior on February 18th. This trough brought spotty light showers to the region, and wind gusts to around 40 mph in the Kern County desert. The main impact on the central and southern San Joaquin Valley was another surge of cold air behind the cold front. High temperatures on February 19th were several degrees cooler than the previous day.

CALIFORNIA, South Central

A trailing short-wave dropped through California on February 20th. This disturbance triggered a couple of afternoon showers near the Southern Sierra Nevada crest, but otherwise had no impact on the central California interior. Temperatures in most locations around the region were a few degrees warmer as the cold air began to moderate.

An upper-level ridge built toward the California coast on the 22nd, and remained near the state the next several days. Temperatures warmed to above normal on February 22nd, and a few degrees warmer on the 23rd before leveling off the next day as the ridge remained just offshore. The upper-level ridge moved onshore on February 24th ahead of an approaching upper-level trough. This brought strong warming to the central and southern San Joaquin Valley, with both Bakersfield (81) and Fresno (77) breaking their record high temperatures for the date by one degree. For Fresno, this broke a record that had stood for 116 years, since 1896. For Bakersfield, this was only the second time this year that the high was in the 80s. The other time was January 2nd, when the high was 82 degrees.

The first in a series of three upper-level troughs reached the California coast on February 25th. Although this storm did not bring any precipitation to the central California interior, it did cool temperatures back to near normal for all areas except the deserts. The second trough approached California the following day. This system split as it neared the coast, with the southern part diving southward parallel to the coast before turning onshore during the evening. As this system moved into southern California, it brought snow to the Kern County mountains. Up to 4 inches fell on the Tehachapi Mountains at the pass level, and Interstate 5 over the Grapevine was closed for several hours during the afternoon of February 27th. Trace amounts of snow fell on Grocer Grade in the Temblors and at Glennville in the Southern Sierra Nevada. Bakersfield received 0.12 inch of rain from the storm, nearly doubling its rainfall for February. The northern part of this storm moved into northern California on the 27th. Upper-level disturbances rotating around the low moved into the central California interior during the late afternoon, triggering showers that continued into the late evening. One shower strengthened as it moved off the Diablo Range into the western San Joaquin Valley, and dropped hail on Interstate 5 northeast of Coalinga. Snow fell as low as the 3000-foot level in the Southern Sierra Nevada, and Lodgepole received 3 inches of new snow. Further north, Yosemite Valley reported an inch of snow. The storm moved into the Great Basin during the early morning hours of February 28th. With available ground moisture, a few patches of fog formed in the central and southern San Joaquin Valley. Otherwise, it was dry in the San Joaquin Valley with temperatures near to a few degrees warmer than the previous day (except at the south end of the Valley where clouds cleared and there were several degrees of warming). The third storm approached the northern California coast during the afternoon of February 28th. A strong upper-level jet dived under the low, and pushed the storm inland during the evening. This storm had better dynamics than its predecessors, and thunderstorms developed along the cold front while it was off shore, continuing as the front moved onto the coast. The storm mainly affected northern California, but it did drop slowly southward during the day on the 29th. Measurable rain finally reached Fresno late in the afternoon of February 29, and Kings and Tulare Counties shortly thereafter. It was locally windy on the west side of the San Joaquin Valley, and over the Kern County mountains and deserts. Nearly a foot of snow fell on the high country of Yosemite National Park, and the Park Service reported that 4 to 6 inches of snow fell of the floor of Yosemite Valley. Further south, up to 9 inches of snow fell in the Southern Sierra Nevada high country in Fresno County, and Lodgepole in Sequoia National Park reported 5 inches of new snow. The rain that fell at Fresno-Yosemite International Airport on âLeap Day,â 0.27 inch, accounted for over a third of the total February rainfall at Fresno (0.75 inch), and was close to the total for February at Meadows Field, Bakersfield (0.29 inch). Despite the series of storms at the end of February, the central California interiorâs rainfall remained well below normal, both for the month and for the rain season. Average temperatures for February were slightly above normal at both Bakersfield and Fresno.

An amplified ridge over the eastern Pacific allowed a few upper-level short wave troughs to move over the region from the 11th through the 13th, resulting in strong, gusty winds and widespread light rain. These passing troughs culminated in a closed upper -level low over San Diego the 14th through the 16th. This cold, closed low dropped south and inland bringing widespread rain and heavy mountain snow to the CWA. On the 14th, San Diego County received the highest rain amounts due to instability showers in the northwest flow behind the shortwave trough axis. Amounts were generally between 0.15 and 0.50 inches of rain, with around three-quarters of an inch on the coastal mountain slopes. Areas above 3500 feet received 2 to 4 inches of snow, with up to 5 inches at 5000 feet. The Riverside County Mountains received 1 to 2 inches of snow above 5000 feet, while the San Bernardino County Mountains fared somewhat better with a trace to 3 inches above 4000 feet and up to 6 inches around 7000 feet. The system stalled out over San Diego for the 15th and 16th. The snow level dropped to around 2800 feet that day. The San Bernardino County Mountains came in with a trace up to 5 inches in the range from 3000 to 6000 feet and generally 6 to 8 inches above 7000 feet, with locally higher amounts of 12 to 14 inches in places such as Idyllwild and Big Bear City. The Riverside County Mountains had higher amounts with 10 to 14 inches above 5000 feet and up to 20 inches around 8000 feet.The San Diego County Mountains received 3 to 6 inches above 3500 feet, including 4 inches of snow in Julian which closed schools in that city on the 13th and 15th. Chain control was required in most mountain locations across the area above 3500 feet. California Highway Patrol even closed Interstate 8 near Pine Valley due to the snow and icy conditions. Rainfall was generally moderate and locally heavy ranging from 0.2 to 0.5 inches in the coast and valley locations, with locally heavier amounts up to 0.8 inches on the mountain slopes. Isolated thunderstorms with accumulating small hail and even a few funnel clouds also occurred in the cold, unstable air behind the front during the morning and early afternoon of the 15th.

A deep, cold trough, associated with its parent upper-level low in the Pacific Northwest, swung through southern California on the 27th, providing the CWA with widespread moderate to locally heavy rainfall and heavy mountain snow. The dynamics were also such that thunderstorms, some with up to pea-sized hail, were also observed. The trajectory of this storm system brought the brunt of the storm through San Diego county providing areas below the snow level and west of the mountains with one-third of an inch to slightly over one inch of rain. Some minor flooding was observed in San Diego County. Orange County and the Inland Empire received less rain, coming in with amounts up to three-quarters of an inch. The snow level was very low with this cold storm, dropping to between 2000 and 2500 feet late in the day. From this level to around 3000 feet had a trace to 3 inches, 3 to 10 inches up to around 7000 feet and up to 14 inches above 7000 feet. Several vehicles slid off the roads in the San Diego County Mountains as well, though no serious injuries were reported. On the lower end of elevation, snow fell as low as 1800 feet in Ramona, however the inch of snow melted later that night. Strong, gusty winds also accompanied this system, most notably in the San Diego County Mountains and the Coachella Valley. San Diego Gas and Electric reported major impacts with this system, including rime ice accumulations on power lines and structures up to a few inches thick.

A slow moving and powerful storm system brought heavy snow to areas in and near the Front Range Foothills, with blizzard conditions over the northeastern plains of Colorado. In the Front Range Foothills, the snow piled up to over 4 feet in some areas. Across the Palmer Divide, the combination of snow and gusty winds resulted in road closures with snow drifts ranging from 2 to 5 feet in depth. Northerly winds 15 to 25 mph were common with gusts to 40 mph. Several snowfall records were also set in Denver. At Denver International Airport, 12.5 inches of snow feet on the 3rd shattered the previous record of 7.5 inches for the date. It also set a new daily record for the entire month of February. A new 3-day record was also established for Denver. The 3-day storm total from February 2nd to the 4th was 15.9 inches, which broke the previous record of 14.1 inches in 1912. In contrast, storm totals generally ranged from 1 to 3 inches in the mountains west of the Continental Divide.

Denver International Airport canceled more than six hundred flights. In addition, snow and blowing snow produced near zero visibilities, forcing officials to close the westbound lanes of Interstate 70, between the Kansas state line and Denver, as well as the eastbound lanes from Denver to Limon. Other road closures included: State Highway 86, between Kiowa and I-70, U.S. Highway 40, between Limon and Eads, and State Highway 71, from Last Chance to Limon to Ordway.

Storm totals along the Front Range Mountains and Foothills included: 51 inches at Coal Creek Canyon, 45.5 inches, 4.6 miles northeast of Ward; 44.5 inches, 3 miles west of Jamestown; 38 inches, 3 miles north of Blackhawk; 37 inches, 3 miles west- southwest of Conifer and 4 miles east-northeast of Nederland; 35.5 inches, 3.6 miles west-northwest of Boulder; 34 inches, 5.2 miles east-southeast of Aspen Springs; 33 inches near Evergreen, 32 inches at Genesee; 31 inches, 10.3 miles west of Bellvue and Eldora Mountain Ski Resort; 30 inches, 10.6 miles west of Livermore; 28 inches; 3.2 miles north-northwest of Horsetooth Mountain; 27 inches at Deadman Hill; 24 inches at Echo Mountain Ski Resort; 21 inches at Niwot Ridge SNOTEL; 19 inches at Gross Reservoir; 15 inches at Bear Lake State Park; with 14 inches near Estes Park and Glen Haven.

A strong upper level jet stream produced high winds in and near the Front Range mountains, foothills and adjacent plains of northeast Colorado. In Boulder, the strong winds snapped power poles and toppled trees. As a result, about 7,000 Xcel Energy customers were without power for several hours. The high winds overturned a tractor-trailer on Foothills Highway overpass, north of Valmont Road. The driver suffered minor injuries. A parked car was totalled when it was crushed by a fallen tree near the University of Boulder. The strong winds were also responsible for two Boulder County wildfires which consumed a total of 65 acres. Colorado Department of Transportation officials closed U.S. 36 at McCaslin Boulevard in both directions after the wind caused damage to the pedestrian overpass. Metal siding from the overpass fell into highway; fortunately there were no injuries. In total, electrical outages affected 46,000 customers along the Front Range. Damage to roofs, siding, garage doors and fences was also reported along the Urban Corridor. In Timnath, the wind knocked a power line on to the roof of the Colorado Feed and Grain building. The ensuing fire partially destroyed the building and forced the evacuation of three people. Across the northeast plains of Colorado the stronger wind gusts were more localized and over a much shorter duration.

A complex multi-part long duration (24 to 36 hour) storm blanketed northern Litchfield County with 4 to 8 inches of snow and sleet on Wednesday, February 29th and Thursday, March 1st. A large low pressure system approached from the upper mid west and Great Lakes region Wednesday. In association with the system's warm front, snow initially overspread the area. As warmer air worked its way into the area Wednesday night, the snow transitioned to a wintry mix. A secondary low began to form in the mid-Atlantic region early Thursday morning. This resulted in a double-barrelled low pressure system which moved eastward during the day Thursday. The wintry mix transitioned back to snow which persisted most of the day. However, the snow had trouble accumulating as temperatures warmed and this limited additional significant accumulations.

Light snow fell during the first half of the day on the 11th in Kent and New Castle Counties in Delaware. Snowfall averaged one to two inches in New Castle County and less than an inch in Kent County. In Sussex County, a mixture of rain and snow fell with little if any accumulation. Because the snow fell overnight on a Friday night into a Saturday morning and most low temperatures were just at or above the freezing mark, there were few weather related incidents. Delaware State Police reported just one disabled vehicle and no snow related accidents. Precipitation started as rain on the evening of the 10th, but changed over to snow during the early morning on the 11th. The snow ended later that morning. Representative snowfall included 1.7 inches in Bear (New Castle County) and the New Castle County Airport, 1.4 inches in Glasgow (New Castle County), 1.3 inches in Newark (New Castle County), 0.8 inches in Blackbird (New Castle County) and 0.5 inches in Dover (Kent County). The snow was caused by the combination of a low pressure system that moved northeast off the North Carolina coast during the early morning on the 11th and an approaching cold front from the west.

Peak wind gusts elsewhere in Delaware were closer to 40 mph. The strongest wind gusts ceased around sunrise on the 12th as the low pressure system started to weaken as it was moving through the Canadian Maritimes.

The strong winds downed weak trees, tree limbs and power lines and caused scattered outages. About 2,000 homes and businesses lost power, hardest hit was Sussex County. Peak wind gusts included 51 mph in Dewey Beach (Sussex County), 48 mph in Lewes (Sussex County), 46 mph at the New Castle County Airport and 43 mph in Dover (Kent County). The strong winds started shortly after a cold frontal passage moved through Delaware during the evening of the 24th and persisted into the first part of the evening on the 25th. Winds started to diminish after the low pressure started to weaken and moved farther away from Delaware.

Strong west winds circulating around an intense low pressure system moving through the Canadian Maritimes (it bottomed at 963 millibars at 1 p.m. EST on the 25th in the Gulf of Saint Lawrence) caused blowout tides in Delaware during the afternoon and evening low tide cycle on the 25th and the morning low tide cycle on the 26th. Tidal departures were two feet below normal on the ocean side and reached three feet below normal on tidal sections of the Delaware River. The lowest tides occurred during the low tide cycle on the 25th and included 1.95 feet below mean lower low water in Lewes (Sussex County) and 2.39 feet below mean lower low water on Reedy Island (New Castle County).

FLORIDA, Northwest

A relatively strong area of low pressure moved through the region during the evening of February 18th and into the overnight hours. Widespread convection with some severe storms and areas of heavy rain accompanied this low pressure system. Convection was aided by very strong wind shear and strong winds just above the surface (around 40-45 knots at 1500-2000 ft AGL). Although instability was minimal, it was still sufficient for some storms to produce severe wind gusts at the surface. In addition, some training of storms occurred with very heavy rainfall amounts in just a few hours. As a result, flash flooding occurred over portions of the eastern Florida panhandle.

A strong cold front moved through the area during the afternoon hours with a 993 mb low centered near Lake Erie. An unusually warm and moist airmass for this time of year was in place across the local area with dewpoints in the upper 60s and SBCAPE values between 1000-1500 j/kg during the morning hours and over 2000 j/kg during the afternoon hours. Shear was also high with 0-1 km shear values around 30 knots and 0-6 km shear values around 70 knots. Farther north across north-central Georgia and Alabama, deep layer shear values were in excess of 80 knots as observed on the morning soundings from BMX and FFC. This combination of instability and shear led to the development of a couple of severe thunderstorms during the afternoon hours. A big limiting factor to the development of stronger tornadoes during the afternoon was the rather straight hodographs and lack of significant directional shear, despite the fact that the speed shear was significant. Note: The estimated wind gust of 50 knots is equivalent to 58 mph.

An EF-1 tornado touched down in Rome just west of the Maplewood Subdivision. EF-1 damage, consisting mostly of uprooted and snapped trees, occurred as the tornado moved in a general easterly direction. The tornado traveled east of Rome and nearly paralleled Kingston Highway, where the most significant damage was sustained near the intersection of Kingston Highway and Freeman Ferry. At this location, a small store lost a significant portion of its roof, and the entire roof was blown off of a single- wide manufactured home. The one indirect fatality associated with the storm occurred at this location, when a 73-year-old woman died of a heart attack after the storm passed. The tornado continued to parallel Kingston Highway, uprooting numerous trees. A couple of outbuildings were damaged or destroyed due to falling trees, and a single-wide manufactured home was heavily damaged when a tree fell on it. The tornado weakened to an EF-0 and finally lifted just east of the intersection of Kingston Highway and Mathis Road. [02/22/12: Tornado #1, County #1-1, EF1, Floyd, 2012:004].

A relatively strong area of low pressure moved through the region during the evening of February 18th and into the overnight hours. Widespread convection with some severe storms and areas of heavy rain accompanied this low pressure system. Convection was aided by very strong wind shear and strong winds just above the surface (around 40-45 knots at 1500-2000 ft AGL). Although instability was minimal, it was still sufficient for some storms to produce severe wind gusts at the surface across southwest and south central Georgia. In addition, heavy rainfall over a several hour period produced some flooding of roadways around the Albany area. Note: The estimated wind gust of 50 knots is equivalent to 58 mph.

The 911 call center reported that scattered trees were blown down in the northern part of the county. Monetary damage was estimated. A strong cold front moved through the area during the afternoon hours with a 993 mb low centered near Lake Erie. An unusually warm and moist airmass for this time of year was in place across the local area with dewpoints in the upper 60s and SBCAPE values between 1000-1500 j/kg during the morning hours and over 2000 j/kg during the afternoon hours. Shear was also high with 0-1 km shear values around 30 knots and 0-6 km shear values around 70 knots. Farther north across north-central Georgia and Alabama, deep layer shear values were in excess of 80 knots as observed on the morning soundings from BMX and FFC. This combination of instability and shear led to the development of some severe thunderstorms during the afternoon hours, including one weak tornado. A big limiting factor to the development of stronger tornadoes during the afternoon was the rather straight hodographs and lack of significant directional shear, despite the fact that the speed shear was significant. Note: The estimated wind gust of 50 knots is equivalent to 58 mph.

Ahead of an upper-level shortwave trough over western Missouri, a mixture of sleet and snow developed from west to east. A strong southerly low-level wind flow of warmth and moisture contributed to the development of precipitation, which eventually changed over to drizzle or freezing drizzle. Snow and sleet accumulations were around one-half inch. Both treated and untreated pavement became covered with the sleet and snow mixture. A trace amount of freezing drizzle added to the hazardous conditions.

A strong upper level low moved northeast out of the southern Rockies into the central U.S. during the night of the 3rd into the day of the 4th. There wasn't a strong reflection at the surface with this storm. Strong isentropic lift, coupled with a layer of unstable air aloft, created significant lift across southern Iowa during the late night hours of the 3rd through mid day on the 4th. The atmosphere was quite warm, so much of the precipitation started out initially as rain or a rain and snow mix. As the stronger dynamics moved into the area, precipitation rates increased and the rain changed to snow. Some thunder occurred with the snow, further enhancing snowfall rates. During the peak of the storm, snowfall rates of 1 to 2 inches per hour occurred with visibility reduced to around 1/4 mile. Winds during the storm were northeast at 15 to 20 MPH, with some higher gusts. Blowing snow was not a major problem as the storm was very springlike in nature with surface temperatures remaining near to just above freezing through the event. The heavy wet snow blanketed west central into parts of southwest and central Iowa. The heaviest snowfall in the Des Moines CWA was in Cass County near Cumberland with 11.5 inches. Other heavy amounts included 9.1 inches at the NWS office in Polk County at Johnston, 8 inches in Union County at Creston and in Dallas County near Waukee, 7.8 inches in Dallas County at Adel, and 7 inches in Audubon County near Gray. The snow caused some travel problems, however with the warm conditions during the snow, and unseasonable warmth prior to the storm, most roads remained wet to slushy except during the period of heaviest snow. By the evening hours, reports indicated that roads were mainly wet with only scattered slick spots.

An intense low pressure area moved from northeast Nebraska, across southern Minnesota, into southern Wisconsin during the night of the 28th through the day on the 29th. The dry low pushed over Iowa during the night and produced gusty southwest winds. During the day, a tropospheric fold developed with the fold reaching down to 540 mb. This helped to enhance wind speeds across the state. High winds begin around sunrise with wind gusts of 69 MPH in the Rockwell City area of Calhoun County by 0740 CST. In Carroll County, the Carroll Mesonet site recorded a 61 MPH wind gust by 0618 CST. Other strong gusts included a 67 MPH wind gust in Dawson, a 61 MPH wind gust in Webster County, and a 60 MPH wind gust near Webster City in Hamilton County. The winds in Hamilton County were accompanied by 2 inches of snow and a brief visibility restriction to about 500 feet. Spotty reports of winds of 55 to 60 MPH were also received, such as a 58 MPH wind gust at Fontanelle in Adair County. Sustained winds of 40 to 45 MPH were common across the high wind warning area through much of the morning into the mid afternoon hours. Winds diminished by the mid to late afternoon hours. Spotty reports of damage were received. A canopy of a gas station was blown off in Calhoun County in Manson. In addition, part of the roof of a school in Manson was ripped off. Tree and power line damage was reported in Carroll and Guthrie Counties in the Coon Rapids area.

A large upper level low pressure system moved from the Rocky Mountains onto the plains. Rain developed ahead of the system and then turned to wet snow during the evening and overnight hours of February 3rd. Although north winds increased into the 15 to 30 mph range, blowing and drifting was limited to a degree by the wetness of the snow. However, the wet snow stuck to trees and caused some tree damage and scattered power outages, mainly from west of Lincoln through Lincoln and into the Omaha/Council Bluffs area. Total snow from the storm was generally 8 to 12 inches with amounts that tapered off to a few inches around Norfolk to Tekamah and 3 to 4 inches from the southeast corner of Nebraska into far southwest Iowa.

A strong area of low pressure crossed Kansas on Monday February 20th. This storm system brought multiple rounds of rainfall to the area through the day. By afternoon, a narrow band of unstable air developed across central Kansas. This instability coupled with strong wind shear to produce a line of strong to severe thunderstorms that tracked from central Kansas into Missouri. There were many reports of pea size hail with a few instances of hail up to the size of quarters. Meanwhile, wind gusts of 45 to 60 mph accompanied the thunderstorms as they passed through.

No specific town was impacted by the tornado, but many rural residences and farmsteads sustained quite a bit of damage in the form of damaged homes and destroyed outbuildings, trailers, and grain bins. On the evening of Tuesday, February 28 2012, a very strong upper level storm system caused widespread thunderstorms to form across most of central and eastern Kansas. The storms initiated approximately 4:00 PM and increased in coverage and intensity throughout the night. Since atmospheric instability was not extremely high there were few reports of severe hail; however, many structures across the area were damaged due to strong, straight-line thunderstorm winds. The most significant event from the evening of February 28 was a strong torando that impacted Harveyville, Kansas at approximately 9:03 pm CST. The town sustained significant damage to some structures, including an apartment complex and a church. On Wednesday, February 29 a National Weather Service survey crew traveled to Harveyville to assess the damage. The survey crew gave a preliminary assessment of EF-2 damage, indicating wind speeds of 111 - 135 mph. Three other tornadoes occurred across the area that night, but not injuries and only marginal damage to outbuildings and structures occurred from these other tornadoes.

KANSAS, North Central

Leading up to this event, the preceding 8 weeks had been unseasonably warm and dry across North Central Kansas, with parts of the area likely drawing ever-closer to receiving a Category D2 (severe) drought designation from the U.S. Drought Monitor. However, this building dryness was quelled during a roughly 42-hour period centered from Thursday evening the 2nd through Saturday afternoon the 4th. Within this time frame, much of the six-county area measured at least 1.00 to 1.50 inches of liquid precipitation in the form of both rain and snow. These precipitation totals were quite notable for early February considering that normal precipitation for the entire month is generally between 0.50 to 0.75-inch. Across most of the area, this precipitation included 2-5 inches of heavy, wet snow, with Long Island in northwest Phillips County reporting a localized 8-inch total. In contrast, most of Mitchell and southern Jewell Counties received little to no snow, although Beloit totaled 1.68 inches of precipitation mostly in the form of rain. According to NWS Cooperative Observers, some of the highest snow amounts fell near Long Island (8.0 inches), Plainville (5.2) and Smith Center (3.4). This heavy, wet snow was accompanied by north winds gusting to around 30 MPH. Examining the timeline and meteorological background of this event, the culprit was a strong mid-upper level low pressures system that strengthened as it neared the Central Plains. Early in this event, temperatures remained warm enough to support rain as the first round of precipitation lifted across North Central Kansas between Thursday evening the 2nd and Friday morning the 3rd. Rainfall amounts from this initial overnight round were commonly between 0.25-inch to over 1 inch, with one of the highest totals through sunrise on the 3rd featuring 1.25 inches at Beloit. During the daylight hours on Friday the 3rd, the majority of the six-county area experienced nothing more than off-and-on light rain or drizzle, while the initial band of heavy snow set up across western and north central Nebraska. Finally, as temperatures cooled on the evening of the 3rd, snow gradually increased in coverage and intensity across northern Kansas. The heaviest snow focused between 7 PM and 11 PM as the mid-level deformation zone pivoted across the area. During the daytime hours on Saturday the 4th, only a few light, lingering snow bands brushed parts of the area.

Jewell County 5 SE Randall 28 1728CST 1732CST 2.36 50 0 0 35.00K 0.00K Tornado (EF0)

A weak tornado, with peak winds estimated at 75 mph, touched down briefly southeast of Randall. Damage consisted of a few broken power poles, sheared off trees and a metal roof being torn from an outbuilding.

KSZ005 Phillips 28 1847CST 0 0 0.00K 0.00K High Wind Although the coverage of storms was limited on this Tuesday afternoon and evening, the first severe thunderstorm event of 2012 featured the first-ever documented February tornado within this six-county portion of North Central Kansas. This EF0 tornado touched down five miles southeast of Randall in Jewell County at 528 PM and tracked east for roughly two miles, tearing a metal roof from a farm outbuilding along the way. Other than this tornado, the only other severe weather report was a 63 MPH wind gust at the Phillipsburg airport, from a combination of strong winds behind a passing cold front and downdrafts from light rain showers falling through dry air. Breaking down the event, a few non-severe elevated thunderstorms lifted from north to south across the area between 10 AM and 12 PM. In the wake of this early activity, modest clearing and resultant destabilization worked into western portions of the area during the early afternoon, in association with an advancing mid level dry slot. As a result, a few non-severe storms first developed into portions of Rooks and Phillips Counties between 215 PM and 3 PM. Around 330 PM, the thunderstorm cluster that would eventually produce the tornado near Randall initiated just south of the area near Interstate 70. As this storm cluster drifted northeast into Osborne, Mitchell and southeast Jewell Counties it became increasingly organized, and rapidly assumed supercell characteristics and strong low-level rotation near and northeast of Beloit, before exiting the local area into Republic and northwest Cloud counties. A few more linear storms affected Jewell and Mitchell Counties after 7 PM, but all thunderstorms exited the six-county area by 8 PM. On the synoptic scale, this was a classic early-season severe weather setup for the area, featuring a strong, negatively tilted mid and upper level trough ejecting out of the Central Rockies into the Central Plains. At the surface, a well-defined surface low pressure system deepened to around 994 millibars as it tracked from east-central Colorado at mid-day, to central Nebraska by late afternoon. To the south of this low, a well-defined cold front and dryline surged east into central Kansas, sparking supercell development. Late afternoon mesoscale parameters revealed a highly-sheared but only modestly unstable environment with surface dewpoints only in the low-mid 50s. Although surface-based CAPE only averaged around 1000 J/kg, both deep layer vertical wind shear and low-level 0-1 kilometer shear were quite impressive, topping out around 70 knots and 30-40 knots, respectively. At the time of the tornado in Jewell County, effective storm relative helicity values were at least 500 m2/s2.

A squall line with embedded sustained supercells entered western Kentucky early in the morning. The embedded supercells raced east-northeast at 60 to 70 mph, while the line moved southeast at a slower rate. The storms strengthened as they encountered richer low-level moisture, with surface dew points around 60 degrees spreading rapidly north-northeastward up the Mississippi Valley. Intense low to mid-level wind fields maintained the intensity of tornadic storms despite weak instability due to lack of solar heating. A south-southwesterly low level jet from 60 to 70 knots veered to west-southwest around 75 knots at 500 mb. By mid-morning, the solid squall line evolved into a broken line of discrete storms over the Pennyrile region and Kentucky Lake region. While these discrete storms maintained severe levels, their tornado production decreased.

Ouachita Parish 1 N Magenta 01 1558CST 0 0 0.00K 0.00K Hail (0.75)

Hail was reported at a motorcycle shop just east of Monroe, Louisiana.

A shortwave trough rapidly traversed east across Oklahoma, Arkansas, and extreme Northeast Texas on February 1st, just ahead of a weak cold front that extended from North Texas, into Southeast Oklahoma and Western Arkansas. The air mass south of the front over Northeast Texas, Southwest Arkansas, and extreme Northern Louisiana destabilized sufficiently as temperatures warmed well into the 70s, within a very moist air mass in place. Cold temperatures and strong instability aloft ahead of this shortwave trough resulted in scattered showers and thunderstorms developing over the region, some of which produced marginally severe to at times, severe hail. These storms exited the region during the late afternoon hours, although additional widely scattered thunderstorms redeveloped during the mid-evening hours over Northwest and Northcentral Louisiana, and again produced a couple of reports of marginally severe hail in and near Monroe, LA. These storms diminished during the late evening, as they moved away from the better forcing near the front as it drifted into extreme Northern Louisiana and Deep East Texas.

The setup was an increasingly unstable and moist atmosphere had just moved into the region in the wake of a warm front which had stalled near the Oklahoma Texas border into Southern Arkansas. Weak disturbances aloft moved into the region from Southeast Texas and Southern Louisiana during the overnight hours. Deep layer shear was sufficient to produce organized strong to severe thunderstorms across the region and given the strong lapse rates in place, hail accompanied some of these thunderstorms.

A storm system began to organize across the southwestern United States Tuesday morning, February 28th, and quickly moved northeast across the Plains and into the Upper Midwest Wednesday morning. Bands of light snow developed on the leading edge of the precipitation, but quickly turned over to a mixture of sleet, snow and freezing rain, before turning back over to snow early Wednesday morning. There were two bands of heavier precipitation during this event. Although some light snow fell the morning of Tuesday, February 28th, the main band developed early Tuesday afternoon, along the Iowa border, with light snow mixed with sleet. It quickly moved northward across most of southern Minnesota by the late afternoon. Most of the precipitation turned over to light rain and sleet south of the Minnesota River, with mostly snow, freezing rain, rain and sleet across the Twin Cities metro area, and west to Litchfield and Glencoe. Most of the precipitation was in the form of snow from west-central into central Minnesota, as well as west-central Wisconsin. Although some sleet, freezing rain and rain was noted prior to midnight as far north as Willmar, St. Cloud, Forest Lake in Minnesota, and around New Richmond, Menomonie and Eau Claire, Wisconsin, heavier bands of snow developed during the evening. Snowfall rates as high as 2 inches per hour were noted with the first band of precipitation prior to midnight. The second band of precipitation moved into far southern Minnesota prior to midnight, and moved northward across all of southern and central Minnesota by morning. Although some sleet, freezing rain and rain was noted on the onset, the mixed precipitation quickly turned over to snow across the Twin Cities, and areas to the north. Snowfall amounts ranged from nearly a foot around Alexandria, Royalton, Mora and Rush City, to a general 6 to 9 inch band from Morris, eastward to St. Cloud, to the northern suburbs of the Twin Cities. Snowfall, combined with sleet and freezing rain dropped substantially south of Redwood Falls, to the southern suburbs of the Twin Cities, where locally one to two inches fell. Along the Iowa border, amounts were generally less than a half inch, with more ice accumulations on trees and power lines than snowfall. This storm prompted classes to be canceled in dozens of school districts, and the University of Minnesota campus in Morris to shut down.

A Colorado low moved up into southwest Minnesota on the morning of the 29th. Temperatures for the morning were quite mild for late February, with many locations across eastern North Dakota and the northwest quarter of Minnesota in the mid 20s to around 30 degrees. Gusty northeast winds in the early morning turned more northerly by late morning, blowing around the fresh snow. Visibilities were poor along Interstate 29 south of Fargo, so the interstate was shut down. Conditions improved rapidly by early afternoon, as there was no cold air surge behind the storm. Afternoon temperatures still ranged in the mid 20s to mid 30s, which allowed the snow to start melting.

A large upper level low pressure system moved from the Rocky Mountains onto the plains. Rain developed ahead of the system and then turned to wet snow during the evening and overnight hours of February 3rd. Although north winds increased into the 15 to 30 mph range, blowing and drifting was limited to a degree by the wetness of the snow. However, the wet snow stuck to trees and caused some tree damage and scattered power outages, mainly from west of Lincoln through Lincoln and into the Omaha/Council Bluffs area. Total snow from the storm was generally 8 to 12 inches with amounts that tapered off to a few inches around Norfolk to Tekamah and 3 to 4 inches from the southeast corner of Nebraska into far southwest Iowa. Although many reports from the storm were in the 8 to 12 inch range, a few locations reported a bit more including around 15 inches in David City and a report of around 14 inches near Lincoln.

Leading up to this significant snow event, the preceding eight weeks had been unseasonably warm and dry across most of South Central Nebraska, with parts of the area likely drawing ever-closer to receiving a Category D2 (severe) drought designation from the U.S. Drought Monitor. However, this all changed during a roughly 42-hour period centered from Thursday evening the 2nd through Saturday afternoon the 4th. Within this time frame, much of the 24-county area experienced its biggest snowfall of the 2011-2012 winter season, with many areas tallying 6-13 inches of heavy, wet snow. Sporadic lightning accompanied some of the heaviest snow bands, resulting in âthundersnow.â In addition to (and prior to) the onset of snow, several counties mainly east of a Franklin to Grand Island line picked up rainfall ranging from 0.25-inch to over 1 inch. As a result, storm-total precipitation amounts from this system were quite notable for early February, and also quite welcome given the recent dry spell, with the majority of the 24-county area totaling between 1-2 inches. For parts of the area, including Hastings, these liquid-equivalent precipitation amounts were the highest on record for any two-day period during the month of February. Focusing on storm total snowfall, the heaviest corridor with amounts averaging at least 7 inches encompassed about 15 counties and was centered roughly 25 miles either side of a line extending from near Holdrege-Minden-Doniphan-Benedict. This corridor of heaviest snow included Grand Island, Hastings and Kearney. According to NWS Cooperative Observers, some of the highest amounts fell at Bradshaw (13.3 inches), Minden (12.2), York (11.0), Hastings (11.0) and Grand Island (9.4). The combination of the heavy, wet snow, along with north winds gusting to around 30 MPH for several hours, resulted in at least minor tree damage and power outages across the area. Outside the zone of heaviest snow, the far northern, western and southern portions of South Central Nebraska saw lesser amounts mainly in the 2-6 inch range, including locations such as Ord, Cozad, Elwood, and Hebron. For some of these areas outside the primary snow zone, this was not even the biggest snow event of the 2011-2012 winter season, with that distinction belonging to early-season December events.

Looking at the timeline and meteorological background of this event, the culprit was a strong mid-upper level low pressure system that strengthened as it neared the Central Plains. Early in this event, temperatures remained warm enough to support rain as the first round of precipitation lifted across mainly eastern portions of South Central Nebraska between the evening of the 2nd and morning of the 3rd. As previously mentioned, rainfall amounts from this initial overnight round were commonly between 0.25 to over 0.75-inch, with one of the highest totals through sunrise on the 3rd featuring 0.97-inch near Shickley in Fillmore County. During the daylight hours on Friday the 3rd, the majority of the 24-county area experienced nothing more than off-and-on light rain or drizzle, while the initial band of heavy snow set up across western and north central Nebraska. Finally, as temperatures cooled on the evening of the 3rd, snow gradually picked up in coverage and intensity across the local area. The heaviest hourly rates of at least 1 inch per hour, along with pockets of thundersnow, focused between 8 PM on the 3rd and 6 AM on the 4th as the mid-level deformation zone pivoted across the area. During the daytime hours on Saturday the 4th, snow gradually decreased in intensity, with most additional accumulations in excess of 2 inches focused along and east of the Highway 281 corridor. One of the few areas where snow totals fell noticeably short of forecasted values included western Dawson County. This was largely due to the fact that concentrated snow bands âjumpedâ over this area, focusing off to the west early in the event, and then re-forming to the east during the evening of the 3rd into the morning of the 4th.

Intense northwest winds buffeted much of South Central Nebraska for several hours on this Thursday, with the strongest sustained speeds around 40 MPH and gusts of at least 50-55 MPH primarily focused west of a line from Ord-Kearney- Holdrege. A few of the highest measured gusts at automated airport sites within the local area included 56 MPH at both Ord and Lexington and 52 MPH at Hastings. These winds resulted in at least minor damage, including a small grain bin blown over in Lexington. Just to the west of the local area, the Broken Bow airport measured a 67 MPH peak gust. These strong winds occurred in the wake of a cold front that passed through during the early morning hours, and were driven by the combination of a tight surface pressure gradient and deep low-level mixing up to at least 800 millibars. The strongest winds focused between the mid-morning and late afternoon hours, as a surface low pressure system deepened to around 990 millibars over southern Missouri. Surface observations at 12 PM revealed a 16-millibar gradient across the state of Nebraska, ranging from 1010 mb in the western Panhandle to around 994 mb in the far southeastern corner of the state.

This brief EF0 tornado touched down four miles west of Greeley at 7 PM and overturned an irrigation pivot. A few hours prior to this, an EF0 tornado near Stapleton in west central Nebraska became the first-ever documented February tornado within the state of Nebraska. In addition to the tornado west of Greeley, a few other notable reports of wind damage in northern portions of South Central Nebraska included a feed grinder overturned near North Loup and an outbuilding destroyed southwest of Belgrade.

NEBRASKA, South Central

Breaking down the event, an initial band of non-severe elevated thunderstorms lifted from north to south across much of South Central Nebraska between 10 AM and 1 PM. In the wake of this early activity, modest clearing and resultant destabilization worked into western portions of the area during the early afternoon, in association with an advancing mid level dry slot. As a result, isolated to scattered thunderstorms developed into portions of mainly Dawson, Gosper, Phelps, Furnas and Harlan Counties between 130 PM-330 PM. One of these storms became an organized low-topped supercell in Phelps and Buffalo Counties between 330 PM-430 PM, but resulted in only pea size hail reports in the Holdrege and Kearney areas. Later in the afternoon and early evening, mainly between 530 PM-830 PM, the coverage of strong to severe thunderstorms increased a bit for areas north of Interstate 80, and also east of Highway 281. The storm mode during this time was primarily comprised of fast -moving line segments with a few pockets of embedded rotation, such as that which produced the tornado near Greeley. By 830 PM, all thunderstorms had exited into eastern Nebraska.

On the synoptic scale, this was a classic early-season severe weather setup for the area, featuring a strong, negatively tilted mid and upper level trough ejecting out of the Central Rockies into the Central Plains. At the surface, a well-defined surface low pressure system deepened to around 994 millibars as it tracked from east-central Colorado at mid-day, to central Nebraska by late afternoon. This allowed a well-defined surface triple point to develop into central Nebraska as a warm lifted north and a trailing cold front surged in from the west. Late afternoon mesoscale parameters revealed a highly-sheared but only modestly unstable environment with surface dewpoints only in the upper 40s to low 50s. Surface-based CAPE averaged under 1000 J/kg, but deep-layer vertical wind shear averaged least 50-60 knots, and low-level 0-1 kilometer shear featured impressive values of 35-50 knots. At the time of the tornado in Greeley County, effective storm relative helicity values were at least 600 m2/s2.

In the wake of the departing storms and surface low pressure system, very strong westerly winds overspread South Central Nebraska, with gusts to around 50 MPH lasting well into the early morning hours of the 29th. The wintry side of this system narrowly missed northern portions of the area, as parts of north central Nebraska received several inches of snow. Note: The estimated wind gust of 52 knots is equivalent to 60 mph.

An inverted surface trough (a reflection of a disturbance farther up in the atmosphere) that extended from a low pressure system that moved west to east through the Carolinas caused a light accumulating snow during the afternoon and evening centered between Interstates 78 and 195 in central and northern New Jersey. The heaviest snowfall occurred during the late afternoon and early evening commute and dropped temperatures at or below the freezing mark. This caused slippery travel on untreated roadways. Snowfall averaged 1 to 2 inches in that corridor with lighter amounts (mainly less than half an inch) elsewhere. The snow began during the afternoon of the 8th and ended that evening. Representative snowfall included 1.8 inches in Howell (Monmouth County), 1.5 inches in Freehold (Monmouth County), 1.3 inches in Stewartsville (Warren County), 1.1 inches in Point Pleasant (Ocean County), 1.0 inch in Cheesequake (Middlesex County), 0.9 inches in Ewing (Mercer County), 0.6 inches in Hillsborough (Somerset County), 0.5 inches in Blairstown (Warren County), 0.4 inches in Florence (Burlington County and 0.3 inches at the Atlantic City International Airport.

Light snow fell during the evening of the 10th into the first half of the day on the 11th in New Jersey. Most of the snowfall was less than an inch, but averaged one to two inches in Salem and Mercer Counties and also in the Raritan Basin. Because the snow fell overnight on a Friday night into a Saturday morning, there were relatively few weather related incidents. The snow started during the evening of the 10th. It was mixed with rain at the start in southern New Jersey mainly south of the Atlantic City Expressway. The snow continued overnight and ended during the morning on the 11th. Representative snowfall included 1.5 inches in Bethlehem (Hunterdon County), South Brunswick (Middlesex County) and Robbinsville (Mercer County), 1.3 inches in Kingwood (Hunterdon County) and Pennington (Mercer County), 1.2 inches in Pittsgrove (Salem County), 1.0 inch in Hammonton (Atlantic County), Bernards (Somerset County), Montgomery (Somerset County) and Ewing (Mercer County) and 0.1 inches at the Atlantci City International Airport. The snow was caused by the combination of a low pressure system that moved northeast off the North Carolina coast during the early morning on the 11th and an approaching cold front from the west.

A mixture of snow, sleet and freezing rain fell over the higher terrain of Sussex County during the daytime on the 16th. Untreated roadways were slippery. Snowfall averaged less than one inch and higher terrain ice accumulations averaged less than one tenth of an inch. Precipitation started as snow during the morning of the 16th and changed to rain in the valleys quickly. Precipitation was slower to change to rain over the higher terrain during the afternoon and it took until the precipitation nearly ended for this to occur in far northwest Sussex County. Representative snowfall included 0.6 inches in High Point and 0.5 inches in Wantage. The wintry mix was caused by precipitation associated with an occluded front that passed through New Jersey around sunrise on the 17th. The southeast flow preceding it was able to bring in warmer air into the county and change precipitation over to rain before it ended.

A low pressure system that passed northwest of New Jersey on the 24th brought a wintry mix of snow and freezing rain to the higher terrain in the northwest part of the state, mainly in Sussex County. Over the higher terrain of Sussex County, snowfall averaged 1 to 3 inches and ice accretions averaged around one tenth of an inch. In the valleys of Sussex County and in Warren and Morris Counties, snowfall was an inch or less and little if any ice occurred. Untreated roadways were hazardous. Precipitation started as a rain and snow mixture around Midnight EST on the 24th. As the precipitation intensity increased, the rain changed to snow and fell heavy at times in the higher terrain around 3 a.m. EST on the 24th. In the valleys, by 5 a.m. EST on the 24th, the snow changed to rain. In the Sussex County higher terrain, it changed to sleet and then freezing rain. Spotty freezing rain continued until precipitation ended late in the morning on the 24th. Snowfall included 3.0 inches in High Point (Sussex County), 2.8 inches in Wantage (Sussex County). 2.0 inches in Montague (Sussex County) 1.5 inches in Vernon (Sussex County), 0.8 inches in Jefferson (Morris County) and 0.5 inches in Blairstown (Warren County). The wintry weather was caused by a low pressure that went southwest to northeast from Kansas on the morning of the 23rd, through the Ohio Valley on the night of the 23rd and into the Saint Lawrence River Valley during the day on the 24th. Precipitation ended as the low's occluded front approached the region. It passed through during the late afternoon on the 24th. There was sufficient cold air in place first aloft and then at the surface for the wintry mix.

A nearly seventy millibar surface pressure difference between an intense low pressure system moving through the Canadian Maritimes (it bottomed at 963 millibars at 1 p.m. EST on the 25th in the Gulf of Saint Lawrence) and a high pressure system in the Central Plains produced nearly twenty-four hours of strong winds (isolated pockets of high winds) across New Jersey from the late evening on the 24th through the early evening on the 25th. The strong winds downed weak trees, tree limbs and power lines and caused scattered outages.

A protracted winter weather event on February 29th and March 1st dropped 1 to 2 inches of snow in Sussex County (less than an inch elsewhere in northwest New Jersey) and was followed by around a quarter inch of ice in the higher terrain in the northwest part of the county. Untreated roadways were hazardous. Snow began during the morning of February 29th and changed briefly to sleet during the early afternoon. The sleet changed to freezing rain over the higher terrain and rain in the valleys during the afternoon on February 29th. Intermittent periods of freezing rain persisted over the higher terrain through the night as warm air struggled to arrive. The freezing rain changed to rain early in the morning on March 1st only a few hours before the event ended. Representative snowfall included 2.3 inches in Wantage (Sussex County), 1.5 inches in Layton (Sussex County), 0.7 inches in Jefferson (Morris County) and 0.5 inches in Blairstown (Warren County) and Butler (Morris County). Four tenths of an inch of ice was measured at High Point (Sussex County) and two tenths of an inch in Wantage (Sussex County). The wintry precipitation was caused by a low pressure system over the upper Mississippi Valley that weakened as it moved east during the day on February 29th. A high pressure system over Quebec Province Canada provided some initially cold and dry air. As the low pressure system moved east into the Great Lakes on the evening of February 29th, a series of secondary low pressure systems formed along the Pennsylvania and Maryland border and moved east. This slowed the advance of warmer air at the surface into northwest New Jersey. By 7 a.m. EST on March 1st, the secondary low pressure systems became equally as strong as the primary low pressure system which reached the eastern Great Lakes. As the secondary lows moved farther offshore later that morning, the precipitation ended in northwest New Jersey.

A complex multi-part long duration (24 to 36 hour) storm blanketed east central New York with 3 up to 15 inches of snow and sleet on Wednesday, February 29th and Thursday, March 1st. A large low pressure system approached from the upper mid west and Great Lakes region Wednesday. In association with the system's warm front, snow initially overspread the area Wednesday with bands of heavy snow occurring with snowfall rates of 1 to 2 inches an hour during the afternoon into the early evening hours. As warmer air worked its way into the area Wednesday night, the snow transitioned to a wintry mix, especially south of the Capital District. To the north and west of the Capital District, heavy snow occurred during the early morning hours Thursday with snowfall rates of 1 to 3 inches an hour. In addition, some sleet mixed in with the snow. A secondary low began to form in the mid-Atlantic region early Thursday morning. This resulted in a double-barrelled low pressure system which moved eastward during the day Thursday. The wintry mix transitioned back to snow which persisted most of the day. However, the snow had trouble accumulating in some locations as temperatures warmed. This limited significant additional accumulations from occurring across the Capital District and points to the south and east. Early Wednesday morning schools mostly in the mid Hudson Valley had announced early dismissals or were closed for the day. By late morning, most schools across east central New York announced early dismissals and cancellations of after-school and evening activities.

The first significant, and overdue, winter storm of the 2011-2012 winter season developed over the central Appalachian region on Sunday, February 19, 2012. Temperatures had been unseasonably warm in the days leading up to the event, resulting in warm ground conditions. It took a timely combination of colder air filtering back into the region from the north throughout the day Sunday, and then heavier bands of precipitation moving across the region late enough in the afternoon and into the evening, to get snow to begin sticking in earnest.

NORTH DAKOTA, East

A hybrid type winter storm system moved out of the Pacific Northwest and into western South Dakota by late evening of the 25th. The surface low tracked from western South Dakota into east central South Dakota by the morning of the 26th, and then up toward Duluth by the early evening of the 26th. It did not seem to be a traditional winter storm system as afternoon highs on the 26th rose into the mid to upper 20s over portions of eastern North Dakota and the northwest quarter of Minnesota. As the system moved into Minnesota on the afternoon of the 26th, north wind speeds increased with gusts over 25 mph commonplace. Snowfall totals generally ranged from 4 to 8 inches across the area. Lidgerwood came in with the highest total of 9 inches.

A Colorado low moved up into southwest Minnesota on the morning of the 29th. Temperatures for the morning were quite mild for late February, with many locations across eastern North Dakota and the northwest quarter of Minnesota in the mid 20s to around 30 degrees. Gusty northeast winds in the early morning turned more northerly by late morning, blowing around the fresh snow. Visibilities were poor along Interstate 29 south of Fargo, so the interstate was shut down. Conditions improved rapidly by early afternoon, as there was no cold air surge behind the storm. Afternoon temperatures still ranged in the mid 20s to mid 30s, which allowed the snow to start melting.

Cold north to northwest winds blowing across Lake Erie caused lake effect snow showers to develop over Northeast Ohio late on February 10th. This snow shower activity intensified during morning hours of the 11th. The snow showers began to taper off from west to east late on the 11th and ended completely around midday on the 12th. Some of the snow was moderate to heavy with visibilities less than a half mile at times on the 11th and again during the early morning hours of the 12th over far Northeast Ohio. Snowfall rates exceeded a half inch per hour at times. North to northwest winds gusted to as much as 25 mph during this event which caused considerable blowing and drifting snow. Snowfall totals of 6 to 10 inches were reported from eastern Cuyahoga and northern Summit Counties across Geauga County and into inland Ashtabula County. Peak totals included 16.1 inches at Pierpont in Ashtabula County; 14.1 inches at Sagamore Hills in Summit County; 11.0 inches at Montville in Geauga County and 10.2 inches at Broadview Heights in Cuyahoga County.

Severe to extreme drought conditions persisted across Osage, Washington, Nowata, and Pawnee Counties during the month of February despite some of this region receiving between 150 and 200 percent of normal rainfall for the month. The Oklahoma Mesonet station near Foraker in Osage County measured 3.89 inches of precipitation during the month while the cooperative observer station near Copan in Washington County measured 3.08 inches and the Oklahoma Mesonet station located near Burbank in Osage County measured 2.80 inches. This above normal rainfall was not as beneficial as it could have been due to the fact that it occurred in a month after which only a few hundredths of an inch of precipitation fell at these same sites. Thus, the long-term lack of precipitation over this region allowed significant drought conditions to persist despite fairly plentiful rainfall this month across these counties. Monetary damage estimates resulting from the drought were not available.

Hail of all sized was reported with the largest being a little smaller than a golf ball.

A shortwave trough rapidly traversed east across Oklahoma, Arkansas, and extreme Northeast Texas on February 1st, just ahead of a weak cold front that extended from North Texas, into Southeast Oklahoma and Western Arkansas. The air mass south of the front over Northeast Texas, Southwest Arkansas, and extreme Northern Louisiana destabilized sufficiently as temperatures warmed well into the 70s, within a very moist air mass in place. Cold temperatures and strong instability aloft ahead of this shortwave trough resulted in scattered showers and thunderstorms developing over the region, some of which produced marginally severe to at times, severe hail. These storms exited the region during the late afternoon hours, although additional widely scattered thunderstorms redeveloped during the mid-evening hours over Northwest and Northcentral Louisiana, and again produced a couple of reports of marginally severe hail in and near Monroe, LA. These storms diminished during the late evening, as they moved away from the better forcing near the front as it drifted into extreme Northern Louisiana and Deep East Texas.

The drought status changed little through the month. An early February snow blanketed a large part of Oklahoma, which provided a nice slow soaking into the soil. Parts of northwest Oklahoma improved its drought status as a result of the increased precipitation. Parts of southwest Oklahoma remained parched, with some lake levels running about 3/4 of capacity. Also, high winds that brought in very dry surface relative humidity dried out some of the near surface moisture, which caused a few wildfires to break out.

An inverted surface trough (a reflection of a disturbance farther up in the atmosphere) that extended from a low pressure system that moved west to east through the Carolinas caused a light accumulating snow mainly during the afternoon and evening of the 8th in Eastern Pennsylvania. The heaviest snowfall did occur during the late afternoon and early evening commute and dropped temperatures at or below the freezing mark. This caused slippery travel on untreated roadways. Snowfall averaged 1 to 2 inches in the Philadelphia suburbs, Berks County and the Lehigh Valley, with lesser amounts elsewhere. The snow began during the early afternoon of the 8th and persisted through most of the evening. The snow was over by the early morning on the 9th. Representative snowfall included 2.0 inches in East Nantmeal (Chester County), 1.9 inches in Kutztown (Berks County), 1.6 inches in Furlong (Bucks County) and Wayne (Delaware County), 1.5 inches in Quakertown (Bucks County), Glendon (Northampton County) and New Tripoli (Lehigh County), 1.2 inches in Alburtis (Berks County), 1.1 inches at the Lehigh Valley International Airport, 1.0 inch in Honey Brook (Chester County), Easton (Northampton County), Jim Thorpe (Carbon County) and Chester (Delaware County) and 0.3 inches at the Philadelphia International Airport.

Light snow fell during the evening of the 10th into the first half of the day on the 11th in Eastern Pennsylvania. Snowfall averaged one to two inches, with lesser amounts in the Lehigh Valley and the Poconos and also in and toward Philadelphia where temperatures were higher. Because the snow fell overnight on a Friday night into a Saturday morning, there were relatively few weather related incidents. The snow started during the evening of the 10th. It was mixed with rain at the start in and around Philadelphia. The snow continued overnight and ended during the morning on the 11th. Representative snowfall included 2.3 inches in Wayne (Delaware County), 1.8 inches in Media (Delaware County) and Wynnewood (Montogomery County), 1.7 inches in Mohnton (Berks County), 1.6 inches in Furlong (Bucks County), 1.5 inches in East Conventry Township (Chester County), 1.3 inches in Gilbertsville and Blue Bell (Montgomery County), 1.2 inches in Huffs Church (Berks County), 1.1 inches in West Chester (Chester County), 1.0 inch in Doylestown (Bucks County) and Royersford (Montgomery County), 0.7 inches at the Lehigh Valley International Airport and 0.3 inches at the Philadelphia International Airport. The snow was caused by the combination of a low pressure system that moved northeast off the North Carolina coast during the early morning on the 11th and an approaching cold front from the west.

Snow showers, some of which were locally heavy at times, reduced visibilities to less than one half of a mile at times in Chester, Delaware and lower Bucks Counties during the second half of the afternoon and evening on the 11th. Localized snowfall reached 1 to 2 inches. This snow was in addition to the snow that fell earlier on the 11th. The reduced visibilities combined with temperatures that fell below freezing caused several traffic accidents. Representative snowfall included 1.9 inches in West Chester (Chester County), 1.5 inches in East Nantmeal (Chester County) and 1.4 inches in Wayne (Delaware County). The snow showers were concentrated along an inverted trough of low pressure which extended westward from a surface low pressure system over the western Atlantic Ocean. An upper air disturbance passing aloft over the area helped to destabilize the air mass and helped manufacture the heavier snow showers.

A low pressure system that passed northwest of the Poconos on the 24th brought a wintry mix of snow and freezing rain to the higher terrain. Mainly just rain fell in the valleys. In the higher terrain, snowfall averaged 1 to 3 inches and ice accretions averaged less than one tenth of an inch. Untreated roadways were hazardous. Precipitation started as snow late in the evening on the 23rd, but changed quickly to rain in the valleys. Over the higher terrain, the snow fell heavy at times early on the 24th and there were even reports of thunder. The snow changed to freezing rain around 5 a.m. EST on the 24th and intermittent light freezing rain continued until around Noon EST on the 24th. Snowfall included 3.1 inches in Tobyhanna (Monroe County), 2.0 inches in Pocono Summit (Monroe County) and 0.5 inches in Albrightsville. The wintry weather was caused by a low pressure that went southwest to northeast from Kansas on the morning of the 23rd, through the Ohio Valley on the night of the 23rd and into the Saint Lawrence River Valley during the day on the 24th. Precipitation ended as the low's occluded front approached the region. It passed through during the late afternoon on the 24th. There was sufficient cold air in place first aloft and then at the surface for the wintry mix.

A nearly seventy millibar surface pressure difference between an intense low pressure system moving through the Canadian Maritimes (it bottomed at 963 millibars at 1 p.m. EST on the 25th in the Gulf of Saint Lawrence) and a high pressure system in the Central Plains produced over twenty-four hours of strong winds in the Poconos and nearly twenty-four hours of strong winds elsewhere across Eastern Pennsylvania from the evening on the 24th through the evening on the 25th. Peak wind gusts averaged 45 to 50 mph and the strong winds downed weak trees, tree limbs and power lines and caused scattered outages. A downed tree by itself knocked out power to 420 Pennsylvania Power and Light customers in Franconia (Montgomery County). In the Lehigh Valley, about 750 Pennsylvania Power and Light customers lost power, most of them in Bethlehem (Northampton County) after a downed tree took down wires.

Snow began during the morning of February 29th and changed briefly to sleet during the early afternoon, The sleet changed to freezing rain over the higher terrain and mainly rain in the valleys during the early afternoon on February 29th. Intermittent periods of freezing rain persisted over the higher terrain through the night as warm air struggled to arrive. The freezing rain changed to rain early in the morning on March 1st only a couple of hours before the event ended.

Representative snowfall included 2.6 inches in Coolbaugh Township (Monroe County), 2.5 inches in Tobyhanna (Monroe County), 1.8 inches in Pocono Summit (Monroe County) and 0.2 inches in Jim Thorpe (Carbon County).

The wintry precipitation was caused by a low pressure system over the upper Mississippi Valley that weakened as it moved east during the day on February 29th. A high pressure system over Quebec Province Canada provided some initially cold and dry air. As the low pressure system moved east into the Great Lakes on the evening of February 29th, a series of secondary low pressure systems formed along the Pennsylvania and Maryland border and moved east. This slowed the advance of warmer air at the surface into the Poconos By 7 a.m. EST on March 1st, the secondary low pressure systems became equally as strong as the primary low pressure system which reached the eastern Great Lakes. As the secondary lows moved farther offshore later that morning, the precipitation ended in the Poconos.

The drought that began in October of 2010, continued to impact the northern Big Country, the Northwest Hill Country and western Crockett County. The drought eased some across the remainder of West Central Texas because of cool, wet weather. Rainfall was near to above normal over most of the area except for the region north of Interstate 20. According to the Texas Crop Report prepared by Texas A&M, pasture and rangeland conditions remained very poor across western Crockett County. The condition of livestock was still generally poor. Most producers were in the calving season and still had to provide supplemental feed. They still found it hard to find alfalfa. When they could find it, the price was extremely high.

Drought conditions continued to improve markedly across Northeast Texas during February of 2012. Several systems affected the region during the month, some of which brought widespread rainfall to the eastern half of the state. To begin the month of February, much of Northeast Texas was classified as D2 Severe or D3 Extreme drought status. By the end of the month, only D2 Severe drought status remained across Northeast Texas. The following are a few selected cities across Northeast Texas with their February rainfall totals and departures from normal as well as the 2012 rainfall totals and departures from normal.

A shortwave trough rapidly traversed east across Oklahoma, Arkansas, and extreme Northeast Texas on February 1st, just ahead of a weak cold front that extended from North Texas, into Southeast Oklahoma and Western Arkansas. The air mass south of the front over Northeast Texas, Southwest Arkansas, and extreme Northern Louisiana destabilized sufficiently as temperatures warmed well into the 70s, within a very moist air mass in place. Cold temperatures and strong instability aloft ahead of this shortwave trough resulted in scattered showers and thunderstorms developing over the region, some of which produced marginally severe to at times, severe hail. These storms exited the region during the late afternoon hours, although additional widely scattered thunderstorms redeveloped during the mid-evening hours over Northwest and Northcentral Louisiana, and again produced a couple of reports of marginally severe hail in and near Monroe, LA. These storms diminished during the late evening, as they moved away from the better forcing near the front as it drifted into extreme Northern Louisiana and Deep East Texas.

Showers and thunderstorms became quite numerous across Northeast Texas into Northern Louisiana during the late night hours of February 2nd into the predawn hours of February 3rd. The setup was an increasingly unstable and moist atmosphere had just moved into the region in the wake of a warm front which had stalled near the Oklahoma Texas border into Southern Arkansas. Weak disturbances aloft moved into the region from Southeast Texas and Southern Louisiana during the overnight hours. Deep layer shear was sufficient to produce organized strong to severe thunderstorms across the region and given the strong lapse rates in place, hail accompanied some of these thunderstorms.

Extreme (D3) to Exceptional (D4) Drought to begin February was relieved across the Rio Grande Valley and Deep South Texas by Valentine's Day, courtesy of a period of cool and damp weather which began with a bang on February 4th, when more than an inch of rain fell across much of the coastal plain. Additional rainfall between the 5th and 13th, combined with frequent cool temperatures and cloud cover, brought a total of 2 to 4 inches for most of the Rio Grande Valley, with 1 to 3 inches for much of the Ranchland east of Zapata County.

A weak upper level disturbance and cold front moving through south Texas acted on a very warm and unstable air mass to produce clusters of thunderstorms during the afternoon of February 4th, which began across the King Ranch of Kenedy and eastern Brooks County, then intensified across Willacy and Cameron County during the mid to late afternoon. The storms brought much needed rainfall, in excess of 1 1/2 inches in less than an hour, to the Lower Rio Grande Valley, along with frequent cloud to ground lightning and gusty winds. The torrential rains produced nuisance poor drainage flooding in portions of Cameron County, and there were unconfirmed reports of funnel clouds and a possible gustnado as the cluster evolved into a small squall line.

Another round of rainfall on February 24th and 25th combined with previously high humidity and one last shot of chilly temperatures allowed additional top soil permeation to close the month. By the 21st, previously Extreme (D3) to Exceptional (D4) conditions had improved to Severe (D2) to Extreme (D4) for most of the region, with a small pocket of Starr County dipping to Moderate (D1) for the first time in nearly a year. After more than a year of well below average precipitation (save for June and December 2011), February's copious rainfall of a general 3 to 5 inches Valley-wide ranked in the top ten wettest all time, and provided much needed drought relief. Despite the rain, most areas remained in critical drought (D2 or greater) at month's end.

The La Nina event weakened during February according to the Climate Prediction Center. South Central Texas saw above normal rainfall and the drought improved across the region. There were several significant rainfall events during the month with precipitation ranging from around one half inch across the Rio Grande Plains to around six inches in parts of Bexar and Williamson Counties. Much of the eastern half of South Central Texas received over two inches. No counties remained in exceptional drought conditions (Stage D4). Bandera, Blanco, Burnet, Edwards, Gillespie, Kerr, Kinney, Llano, Real, and Williamson Counties improved to extreme drought category (Stage D3) while Val Verde County remained in this category. Bastrop, De Witt, Dimmit, Fayette, Frio, Gonzales, Karnes, Kendall, Lavaca, Lee, Medina, Travis, Uvalde, and Zavala Counties improved to severe drought conditions (Stage D2). Atascosa, Bexar, Caldwell, Comal, Guadalupe, Hays, and Wilson Counties improved to moderate drought (Stage D1). Due to recent rain only 11 counties still had burn bans in effect. At the end of the month the seven day stream flow average remained in the normal to much below normal range for basins across South Central Texas and the Rio Grande Plains. Area lakes and reservoirs had some improvement, but remained well below normal pool elevations with Lake Travis around 50 feet below normal and Medina Lake near 53 feet below.

Drought conditions as reflected by the U.S. Drought Monitor were unchanged from the end of January. Exceptional (D4) drought persisted over much of the South Plains while the Rolling Plains saw values ranging from Abnormally Dry (D0) in Hall County to Severe (D3). February was abnormally cool for a typical La Niña pattern that had been observed through the fall and winter. Average temperatures for the month at Lubbock and Childress were just below normal. These lower temperatures greatly reduced instances of grassland wildfire starts. The first half of February brought mostly dry conditions but two widespread precipitation events occurred in the second half of the month in the form of winter weather. Despite these two precipitation events, much of the area was below normal for precipitation totals. Keetch-Byram Drought Index values remained unchanged from January. Values ranged from 500-600 across the South Plains and 300-400 across the Rolling Plains. Soil moisture deficits experienced modest improvements by mid-month after a few rounds of precipitation. However, deep soil moisture levels were not improved. A strong wind event on the 20th damaged some winter wheat crops in the Rolling Plains due to widespread blowing dust. Livestock was generally reported to be in fair to good condition with a continued dependence on supplemental feed. Economic losses due to drought through February since the drought began were estimated near $2.4 billion.

An upper level storm system pushed from the Great Basin through the central Rockies and onto the Southern Plains on the 12th. Relatively warm and moist air overspread a low level arctic airmass entrenched across West Texas. This system brought widespread significant snowfall to the region throughout the entire day. Snow and sleet showers began over the western South Plains during the pre-dawn hours. Snowfall then spread to the rest of the South Plains by the rest of the morning and then to the Rolling Plains by the mid-afternoon. Several brief and scattered heavy snow showers brought up to one inch per hour snowfall rates during the afternoon and evening. Most snow tapered off late in the evening but light freezing drizzle and sleet persisted into the early morning hours of the 13th. Numerous traffic accidents were reported throughout the region with a majority of incidents occurring in Lubbock.

Although a few rainfall events occurred over western north Texas, it wasn't enough to affect the ongoing D4 drought. The early month cold start put a halt on the early season green-up, although a return to spring-like temperatures occurred during the latter half of the month, which allowed for the early season growth to continue. Strong winds during the latter half of the month may have done more harm than good, by drying out some of the recent near soil moisture. This resulted in a few wildfires.

Intermittent light rain and snow began after dawn. The cooling aloft and the deeper moisture associated with the comma head signature on satellite imagery moved through during the afternoon. As a result, wet snow became steady after 1200E. The snow fell at a rate of around an inch per hour during much of the afternoon. With the warm ground, and air temperatures at or slightly above freezing in the valleys, a highly elevation dependent accumulation was seen. Snow accumulations of 3 to 8 inches were common.

The first significant, and overdue, winter storm of the 2011-2012 winter season developed over the central Appalachian region on Sunday, February 19, 2012. Temperatures had been unseasonably warm in the days leading up to the event, resulting in warm ground conditions. It took a timely combination of colder air filtering back into the region from the north throughout the day Sunday, and then heavier bands of precipitation moving across the region late enough in the afternoon and into the evening, to get snow to begin sticking in earnest. At the conclusion, a generous swath of five to eight inches of snow fell across most of the forecast area in Virginia, with some localized nine inch amounts. Areas of southside Virginia the NC border received less snow, more on the order of three to four inches.

The first significant, and overdue, winter storm of the 2011-2012 winter season developed over the central Appalachian region on Sunday, February 19, 2012. Temperatures had been unseasonably warm in the days leading up to the event, resulting in warm ground conditions. It took a timely combination of colder air filtering back into the region from the north throughout the day Sunday, and then heavier bands of precipitation moving across the region late enough in the afternoon and into the evening, to get snow to begin sticking in earnest. At the conclusion, an average of five to nine inches of snow covered most of southeast West Virginia.

WEST VIRGINIA, West

A southern stream disturbance in the winds aloft helped initiate snow during the late afternoon hours of Friday, the 10th. Snow accumulations of 1 to 4 inches were common by dawn on Saturday across the mountainous counties. An arctic cold front blew through between 0800E and 1100E on Saturday, the 11th, enhancing the snowfall. Some electrical power outages occurred as winds gusted into the 30 to 40 mph range. Temperatures dropped from the 20s through the teens during that afternoon, with single digits for elevations above 4000 feet. The steady snow turned into wind blown snow showers of varying intensity through the night, before diminishing to flurries on the morning of the 12th. The main accumulation period was from the predawn to late afternoon on the 12th. The drier arctic air limited the snow accumulations overnight Saturday night, despite good crystal growth temperatures in the lingering low level moisture.

A snow cover of 1 to 3 inches was on the ground prior to this episode. Across Randolph, Webster, and Nicholas Counties new snow accumulations were 4 to 6 inches in a few valleys, but 8 to 10 inches across the high terrain and through the valleys favored by the banded snow showers. The snow depth at Kumbrabow State Forest went from 3 inches prior to the storm to 12 inches. Snow depths of around a foot were also reported around Helvetia and Pickens. The snow depth at Hacker Valley and Mt Nebo increased 7 inches. Even in the Leading Creek Valley, Montrose had a final snow depth around 10 inches.

In Upshur County, snow accumulations of 4 to 7 inches were observed. For example, Buckhannon measured 5 inches of accumulation, while Rock Cave had 6 inches. In Pocahontas County, the upslope region around Snowshoe and Slatyfork saw 5 to 8, but the majority of the county had less, mostly 1 to 3 inches. Across Barbour, Lewis, Braxton, Fayette, and Raleigh Counties, snow accumulations of 2 to 5 inches occurred.

As a surface low pressure system was moving east, off the southeast coast of the United States, its mid and upper level system was lifting northeast, out of the Tennessee Valley on Sunday, the 19th. Intermittent light rain and snow began during the mid and late morning across southern West Virginia. This was on the northern edge of the precipitation shield. The cooling aloft and the deeper moisture associated with the comma head signature on satellite imagery moved through during the mid afternoon into the early evening. As a result, wet snow became steady after 1300E. The snow fell at a rate of around an inch per hour during the mid and late afternoon. Air temperatures were at, or slightly above, freezing. The ground was relatively warm. As a result, a highly elevation dependent accumulation was seen across the steep terrain of the southern coal fields and through the southern mountains. Snow accumulations of 3 to 6 inches were measured in Logan, Mingo, Wyoming, McDowell, and Fayette Counties. In Raleigh County, the western valleys still have around 3 inches of snow. However, the southern plateau around Beckley to Ghent saw a 6 to 8 inch snow accumulation. The snow ended during the evening. Trees or tree branches came down on overhead wires. Pine trees were favored. Other wires sagged due to the weight of the snow. In the 6 counties, a total of nearly 10,000 customers lost electricity. Of these counties, Raleigh County had the most outages by far, having more than half the total.

Strong cold air advection during the afternoon caused winds to increase. Wind gusts of 40 to 50 mph were widespread across the western lowlands and mountainous counties during the 1500E to 1900E period. A few stronger gusts were observed.

However, the ground was quite wet and soft, due to the heavy rain earlier in the day. Several of the fallen trees were along hill slopes. One mobile home was shaken by the wind with damage to its metal skirting. One small barn had half of its corrugated zinc metal roof blown off. The roof ended up about 150 feet northeast of the barn. The barn had an open design, which allowed the wind to enter the barn and lift off the east-facing side of the roof. The opposite side of the roof was undamaged.

Ahead of a warm front, showers and embedded thunderstorms began before dawn on Wednesday, the 29th. The warm front lifted northeast through West Virginia between dawn and midday. By late afternoon that warm front had lifted into the northern panhandle and southwestern Pennsylvania. In the warm sector, the showers diminished by late morning and midday across the southern half of West Virginia. However, despite being just south of the warm front, showers and thunderstorms continued during the afternoon near the Route 50 corridor across northern West Virginia. The heaviest rain rates fell during the late morning into the early afternoon hours. Around 0.75 inches of rain fell in less than 3 hours. By mid afternoon, 8 to 12 hour rain totals of 1 to 1.5 inches were common from near Wood, Pleasants, and Tyler Counties on east into Harrison, Taylor, Lewis, and Upshur Counties. Rain totals of 1.5 to 2.5 inches were common in 24 hours. A local maximum of 2.6 inches was measured at Kesling Mill in northern Upshur County. A more extensive 24 hour rainfall maximum of 2.5 to 3 inches stretched across northern Harrison into northern Taylor Counties. This was toward the border with Marion and Preston Counties. For example, Valley Falls State Park reported 2.7 inches by 1800E on the 29th. Prior to the rain, the ground was already wetter than normal. The vegetation was still dormant. As a result, small streams flooded quickly. Urban street and poor drainage flooding also occurred. While the flooding was occurring, instability increased during the afternoon over southern West Virginia, ahead of an approaching cold front. These additional showers and thunderstorms did produce some hail and wind damage during the mid and late afternoon. Luckily, the heaviest downpours remained mostly south of the areas hit harder earlier in the day. Governor Earl Ray Tomblin declared a state of emergency due to the flooding. This event would be combined with another severe weather event on March 2nd to be declared a federal disaster by President Barack Obama. See FEMA disaster number 4059 for more details.

WISCONSIN, Southeast

Heavy, wet snow accumulated to 3 to 6 inches over much of southern Wisconsin as surface low pressure tracked across Illinois. Strong warm-air advection led to strong frontogenetic forcing over the region, with lift enhanced by differential positive vorticity advection associated with a 500-mb short-wave trough that crossed the region. These features produced a steady, long -term snowfall that began in the early evening of the 23rd and lasted until the early morning hours of the 24th. A few locations (West Bend to Mt. Mary College in Milwaukee and from Burlington to the city of Racine) received between 7 to 8 inches of accumulation, but these higher amounts were isolated and had a low impact on travel. Therefore, this event was not documented as a winter storm.

WIZ052 Sheboygan 26 1200CST 1400CST 0 0 1.0K Strong Wind

Gusty south to southeast winds affected the eastern counties of Southeast Wisconsin around the mid-day hours of February 26th. The gusty winds were produced in a tightening pressure gradient ahead of strong low pressure that tracked across central Minnesota to the Upper Peninsula of Michigan. The strong winds would have occurred over a longer period of time, but the start was delayed until a low-level inversion over a snow cover across the area mixed out with daytime heating. The Sheboygan C-MAN recorded sustained winds of 32 to 39 mph (28 knots to 32 knots), with a peak gust of 45 mph (39 knots), while the Sheboygan airport reported a peak gust of 43 mph. Wind gusts over the remainder of southeast Wisconsin were in the 35 to 43 mph range, which was below strong wind criteria.

A storm system began to organize across the southwestern United States Tuesday morning, February 28th, and quickly moved northeast across the Plains and into the Upper Midwest Wednesday morning. Bands of light snow developed on the leading edge of the precipitation, but quickly turned over to a mixture of sleet, snow and freezing rain, before turning back over to snow early Wednesday morning. There were two bands of heavier precipitation with this event. Although some light snow fell the morning of Tuesday, February 28th, the main band developed early Tuesday afternoon, along the Iowa border, with light snow mixed with sleet. It quickly moved northward across most of southern Minnesota, into west-central Wisconsin by the late afternoon.

Most of the precipitation was in the form of snow from west-central into central Minnesota, as well as west-central Wisconsin. Although some sleet, freezing rain and rain was noted prior to midnight as far north as Willmar, St. Cloud, Forest Lake in Minnesota, and around New Richmond, Menomonie and Eau Claire, Wisconsin, heavier bands of snow developed during the evening. Snowfall rates as high as 2 inches per hour were noted with the first band of precipitation prior to midnight.

The second band of precipitation moved into far southern Minnesota prior to midnight, and moved north and northeast across all of southern and into west-central Wisconsin by morning.

Storm Data Disclosure

Storm Data is an official publication of the National Oceanic and Atmospheric Administration (NOAA) which documents the occurrence of storms and other significant weather phenomena having sufficient intensity to cause loss of life, injuries, significant property damage, and/or disruption to commerce. In addition, it is a partial record of other significant meteorological events, such as record maximum or minimum temperatures or precipitation that occurs in connection with another event.

Some of the information appearing in Storm Data may have been provided by or gathered from sources outside the National Weather Service (NWS), such as the media, law enforcement and/or other government agencies, private companies, individuals, etc. An effort is made to use the best available information, but because of time and resource constraints, information from these sources may be unverified by the NWS. Therefore, when using information from Storm Data, customers should be cautious as the NWS does not guarantee the accuracy or validity of the information. Further, when it is apparent information appearing in Storm Data originated from a source outside the National Weather Service (frequently credit is provided), Storm Data customers requiring additional information should contact that source directly. In most cases, NWS employees will not have the knowledge to respond to such requests. In cases of legal proceedings, under Department of Commerce regulations and/or rules of the court, NWS employees are not legally obligated to provide written or verbal testimony.

Fatality Codes: For events that include a fatality, there is a code containing the gender, age and fatality location at the end of the event narrative. 1st -letter: Gender (M/F) / 2nd -numbers: Age / 3rd -letters: Fatality location (see table below) Example: M51IW – Male, 51 years of age, fatality occurred In Water.

Other Notes:

An “Episode” is an entire storm system and can contain many different types of events.

An “Event” is an individual type of storm event.

When listing wind speed values under “Character of Storm”, i.e. High Wind (G81): The G indicates a “Gust” which is a peak 5-second averaged wind speed in Knots (kts). 1 kt. = 1.152 mph. This number can be either E (estimated) by damage caused, or M (measured) by known calibrated anemometers. Examples: (M61) = measured 61 knots; (E75) = estimated at 75 knots.

All wind speeds listed are estimated by NWS personnel by the amount and type of damage unless otherwise noted with an “M” which represents an actual wind speed as measured by official NWS approved anemometer.

When listing hail size under “Character of Storm”, ex. Hail (2.25), the hail size is given in inches and hundredths of inches.

When listing property and crop damage, the figures indicated are the best guess made by the NWS from the available sources of information at the time of the printing.

The fatalities, injuries, and damage amounts appearing in tropical cyclone events are attributed only to wind damage experienced in the coastal counties/parishes listed. Other tropical cyclone related events such as tornadoes and flooding are listed within their separate event types.

The Saffir-Simpson Scale

Category One Hurricane:

Winds 74-95 mph (64-82 kts or 119-153 kph). Storm surge generally 4-5 ft above normal. No real damage to building structures. Damage primarily to unanchored mobile homes, shrubbery, and trees. Some damage to poorly constructed signs. Also, some coastal road flooding and minor pier damage.

Category Two Hurricane:

Winds 96-110 mph (83-95 kts or 154-177 kph). Storm surge generally 6-8 feet above normal. Some roofing material, door, and window damage of buildings. Considerable damage to shrubbery and trees with some trees blown down. Considerable damage to mobile homes, poorly constructed signs, and piers. Coastal and low-lying escape routes flood 2-4 hours before arrival of the hurricane center. Small craft in unprotected anchorages break moorings.

Category Three Hurricane:

Winds 111-130 mph (96-113 kts or 178-209 kph). Storm surge generally 9-12 ft above normal. Some structural damage to small residences and utility buildings with a minor amount of curtainwall failures. Damage to shrubbery and trees with foliage blown off trees and large trees blown down. Mobile homes and poorly constructed signs are destroyed. Low-lying escape routes are cut by rising water 3-5 hours before arrival of the hurricane center. Flooding near the coast destroys smaller structures with larger structures damaged by battering of floating debris. Terrain continuously lower than 5 ft above mean sea level may be flooded inland 8 miles (13 km) or more. Evacuation of low-lying residences with several blocks of the shoreline may be required.

Category Four Hurricane:

Winds 131-155 mph (114-135 kts or 210-249 kph). Storm surge generally 13-18 ft above normal. More extensive curtainwall failures with some complete roof structure failures on small residences. Shrubs, trees, and all signs are blown down. Complete destruction of mobile homes. Extensive damage to doors and windows. Low-lying escape routes may be cut by rising water 3-5 hours before arrival of the hurricane center. Major damage to lower floors of structures near the shore. Terrain lower than 10 ft above sea level may be flooded requiring massive evacuation of residential areas as far inland as 6 miles (10 km).

Category Five Hurricane:

Winds greater than 155 mph (135 kts or 249 kph). Storm surge generally greater than 18 ft above normal. Complete roof failure on many residences and industrial buildings. Some complete building failures with small utility buildings blown over or away. All shrubs, trees, and signs blown down. Complete destruction of mobile homes. Severe and extensive window and door damage. Low-lying escape routes are cut by rising water 3-5 hours before arrival of the hurricane center. Major damage to lower floors of all structures located less than 15 ft above sea level and within 500 yards of the shoreline. Massive evacuation of residential areas on low ground within 5-10 miles (8-16 km) of the shoreline may be required.
