OUTSTANDING STORM OF THE MONTH

7.75” Diameter Hailstone Sets a New Record for Kansas

A combination of a low pressure area along the Kansas-Oklahoma border, and an outflow boundary across South Central Kansas, led to the development of supercell thunderstorms across that South Central Kansas region on September 15th. The supercells’ thunderstorms were noted for producing very large hail. A few weak tornadoes were also produced, with all the tornadoes moving across open country.

Two supercell thunderstorms left a destructive swath of hail across portions of Sedgwick County. This swath was approximately 5 miles wide and 15 miles long, stretching from northwest of Goddard, Kansas through the western and southern half of Wichita to near Rose Hill, Kansas. Hail as large as softball and grapefruit size pounded roofs and cars along its path with over 35,000 claims turned into insurance agencies. The hail-damaged roofs made the area look like a war zone, with holes having been gouged big enough for people to stick their heads through. Cars and golf courses were pock-marked with large dents. Some of the hail came through the roof of the terminal at the Mid Continent Airport. Three commercial airliners were damaged and had to be towed to hangers for repairs. The National Weather Service in Wichita suffered damage to its vehicles, including one hail dent that was almost 10 inches across.

A hailstone that fell 2 miles west of the National Weather Service office broke the state record for diameter, measuring 7.75 inches across. However, the official weight and circumference were not obtained until 15 hours after the stone had fallen. At that time the stone weighed 1.1 pounds and had a circumference of 15.5 inches. Members of the six-person State Climate Extremes Committee declared that the hailstone was the state's largest diameter stone to ever have fallen.

Despite the destruction wrought by the hail and strong thunderstorm winds ($150 million dollars worth), no injuries were reported.

An intensifying low moved south across the Arctic Ocean and deepened to 990 millibars about 350 miles north of Barrow by the morning of the 25th. Sea ice was near seasonal minimums and there was several hundred miles of open water to the northwest of Barrow. A northwest wind around the back side of the low increased to sustained speeds of 20 to 30 mph with gusts to 40 mph. The strong wind caused seas to build to an estimated 5 to 10 feet that broke along the beach. Seas were estimated to be as high as 15 feet offshore. Although the storm surge was estimated to be less than 1 foot, the high seas did cause some minor flooding around Barrow. The road that runs parallel to the beach was closed due to minor flooding. Minor flooding was also reported at the public playground and in low lying areas near the Top of the World Hotel. The boat ramp was also reported to be flooding. No property damage was reported during the storm. The city built up berms that were estimated to be 6 feet high and the berms likely helped to mitigate flood damage.

A strong low moved into the Gulf of Alaska. This storm, coupled with high pressure over interior Alaska produced strong north winds across the region and through the channeled terrain of south central Alaska. Over 10,000 people lost electric power in the south central region as a result of the high wind. The strongest wind observed was a 78 mph gust in the Palmer Wasilla area. This strong wind event occurred early in the fall while trees still had leaves on them. This resulted in an uncharacteristically high number of trees being blown down, some of which fell across power-lines causing the unusually high number of power outages. Based upon insurance company information, it is estimated that $500,000 of damage occurred from this storm in the Matanuska Valley to the Anchorage area.

Shower and thunderstorm development on the northern periphery of the remnants of Tropical Storm Hermine affected portions of northwest Arkansas beginning on September 7th, while the center was still over central Texas. Light to moderate rain continued through the 8th over much of the region and then became much heavier as the center of the storm moved from southwest Oklahoma into northeast Oklahoma late on the 8th and during the early morning hours of the 9th. The heaviest rainfall totals occurred just east of the storm track. Rainfall rates of over two inches per hour and rainfall totals of eight to fourteen inches across east central Oklahoma and northwest Arkansas led to widespread flash flooding during the morning hours of the 9th. The heaviest swath of rain occurred across Crawford and southern Washington Counties in Arkansas, which is where some of the worst flooding occurred. The following locations received in excess of seven inches of rain during the event, much of which fell during a several hour period during the early morning hours of the 9th: 9.81 inches in Mountainburg in Crawford County and 9.00 inches in Natural Dam in Crawford County. Many small creeks and streams rose very quickly from this rainfall. Frog Bayou in Crawford County crested at 16.99 feet at the Rudy gage site by the afternoon of the 9th, overtopping the Highway 282 bridge. The water rose about sixteen feet in only six hours (from about 7 a.m. to about 1 p.m.) at this site. Emergency officials performed numerous swift water rescues and many roads were closed due to the high water throughout the area. Several small bridges and low water crossings were washed out. Mainstem river flooding was minimized since much of the rainfall and runoff was contained by Eufaula Lake and R.S. Kerr Reservoir. However, high lake levels at Kerr Reservoir resulted in high outflow downstream of Kerr, which resulted in brief minor flooding along the Arkansas River at Van Buren.

The Fourmile Canyon Wildfire, northwest of Boulder, broke out Monday morning. It originated from an unattended fire pit at a local residence. The wildfire quickly consumed 5 1/2 square miles or 3,500 acres the first day, and forced the evacuation of over 3,000 residents. Erratic 45-mph gusts sent the fire in two directions at times. Very dry weather conditions preceded the fire. The combination of strong winds, low relative humidities and dry fuels allowed the wildfire spread rapidly through the steep, heavily forested terrain. The flames were reportedly 20 to 50 feet in length. Towns within the burn area included Salina, Wallstreet and Gold Hill. The dry conditions coupled with gusty winds ranging from 45 to 64 mph persisted for several more days. Fire managers used as many as 700 firefighters and support personnel from 35 agencies and seven air tankers to battle the wildfire. A total of 6,181 square acres or approximately 10 square miles were burned. The Fourmile Canyon Wildfire was the most destructive fire in Colorado history in terms of the damage to personal property. It destroyed 171 homes with an estimated cost of 217 million dollars.

The combination of strong south to southeast winds during the day and evening on the 30th and periods of heavy rain downed tree limbs and wires in Delaware. Peak wind gusts averaged 40 to 45 mph. The combination of the southeast winds and fresh water runoff also caused widespread minor tidal flooding with the late afternoon high tide along the tidal sections of the Delaware River and its tributaries on the 30th. The afternoon high tide reached 7.60 feet above mean lower low water at Reedy Point (New Castle County). Minor tidal flooding starts at 7.2 feet above mean lower low water while moderate tidal flooding starts at 8.2 feet above mean lower low water. Peak wind gusts included 44 mph in Georgetown (Sussex County) and 43 mph at the New Castle County Airport. The strong wind was caused by the pressure difference between a high pressure system off the Eastern Seaboard and a low pressure system that moved from North Carolina north into Pennsylvania during the day on the 30th. As the initial low pressure system weakened and the frontal boundary moved closer to Delaware, winds diminished overnight on the 30th.

The public reported damage to a light fixture in a home caused by a lightning strike. Other non-specific minor damage was also observed as a result of the lightning strike. An unseasonably strong summerlike subtropical ridge continued across the southeast U.S. As a consequence, temperatures remained well above normal late into the month, with high temperatures in the 90s many days. The western edge of the subtropical ridge was beginning to weaken during the last week of September, allowing moisture and better dynamics to creep into the western part of the state. With the abnormally high temperatures for late September, isolated to scattered thunderstorms developed across west central and parts of central Georgia during the mid and late afternoon hours and continued into the evening hours. The storms were brief, but did produce strong downburst wind gusts and frequent cloud-to- ground lightning. The storms generally dissipated after sunset, but isolated showers and thunderstorms redeveloped and spread into northwest Georgia during the late night and early morning hours, resulting in yet another lightning-related incident during the early morning hours of the 22nd.

One home suffered minor flood damage in addition to debris removal from the flooded roads. An upper trough across the Ohio and Tennessee Valley was dropping south into the southeast U.S. and rapidly trending toward a deep, cold core upper low. The first wave of inclement weather associated with this system occurred as an area of widespread moderate to heavy rain, with a line of strong thunderstorms along the leading edge. While none of these thunderstorms became severe on the 26th, tornado watches were in effect for much of north and central Georgia during the afternoon and evening and some storms along the leading edge of activity exhibited at least weak mesocyclones across east central Georgia. A tornado warning was issued for a storm in southern Wilkes county during the late afternoon. However, no tornado developed with this storm. Widespread rainfall of two to three inches was common across east and south Georgia, with rainfall in excess of four inches in parts of Oglethorpe county. Some flooding was observed in the Warner Robins area during the evening where rainfall of three to four inches was common. This was the first widespread rain for the area since late August, so flooding in general was not an issue, despite the heavy rainfall.

GEORGIA, North and Central

The eastern U.S. upper trough noted on the 26th of September continued to evolve into a deep upper low across the southeast U.S. with an associated pocket of cold temperatures aloft. Temperatures aloft at 500mb were near -20C during the late afternoon and early evening hours of September 27th. As the preceding area of rain and thunderstorms exited the area to the east during the afternoon, cloudy conditions across north and west Georgia gave way to partly sunny skies. This allowed temperatures to warm into the low and mid 80s across the region. The warm surface temperatures created a very unstable environment as the upper low and cold core pocket rotated across the region. Scattered to numerous thunderstorms developed across north Georgia, with lesser coverage of convective activity across central Georgia. Only the southwest part of the county warning area managed to escape the afternoon thunderstorms. The thunderstorms were fast moving, but several produced damaging downburst winds and penny to occasionally golf ball-sized hail. A strong shower on the tail end of the convective activity (no lightning observed) even produced a brief tornado in Laurens county in southeast Georgia. The severe weather event only lasted a couple of hours in the 530 pm to 730 pm time frame.

September 2010 was one of the hottest and driest months of September on record. Because similar conditions prevailed during August, drought conditions intensified during September. Near the end of the month nearly one half of Indiana was experiencing moderate (D1) to severe (D2) drought conditions according to the U.S. Drought Monitor. Numerous field fires occurred on several days during the month, the most since September 1999. September 2010 was another very dry month for central and southern Indiana. Measurable rain fell on only 4 to 8 days during September. An inch or more of rain fell on 1 day at a few locations. Many central Indiana areas received little or no rain for 1 to 2 weeks stretches during the month. In portions of south central Indiana, some areas received little rain for the entire month. The abnormally dry conditions of late August intensified during September. The drought conditions during the month lead to numerous field fires across Indiana. Field fires were known to have occurred on the 1st, 13th, 15th, 16th, 21st, 23rd, and 30th. One fire on the 23rd in Rush County charred nearly 1,000 acres and threatened the small town of Williamstown. Other field fires during the month destroyed one rural house in Morgan County and damage one home in Marion County. According to Indiana Forestry, some of these field fires were almost totally out of control. On the last day of September, a forest fire broke out in Jackson County. The large fires during September coincided with the warm to hot temperatures, low relative humidity values, and moderate to strong winds. Burning bans existed in 62 out of 92 Indiana counties on October 1 because of dry conditions.

Up to 6 inches of water was flowing over County Road J43 near Delphos.

A quasi-stationary front was located south of Iowa as an upper level shortwave advanced across the area in strong westerly flow aloft. The atmosphere was somewhat unstable, albeit the instability was elevated in nature. Available CAPE was in the 1000 to 2000 J/kg range with lifted indices of -3 to -5 C. Moisture had pooled over the area with precipitable water values in the 1.3 to 1.7 inch range. The freezing level was quite high for mid September at between 14,000 and 14,500 feet. Significant shear was present in the atmosphere with 50 to 60 kts of effective shear present. Other severe parameters were not all that strong. Downdraft CAPE was less than 500 J/kg and the hail index showed 300 to 500 J/kg in the -10 to -30 C layer of the atmosphere. The LCL was under 500 meters, however a strong inversion was present. Thunderstorms developed in the evening and produced hail and heavy rain quite easily. The cold surface temperatures, in the upper 40s to low 50s, helped maintain the hail size from these storms and overcame the high freezing level. Storms in southwest Iowa produced the largest hail with golf ball size hail reported west of Bedford, and tennis ball size hail reported in the town of Bedford in Taylor County. Hail up to three inches in diameter fell in Cass County south of Cumberland. Storms farther east produced marginal hail with reports of nickel to quarter size hail received in central Iowa. Several supercells moved across Taylor, Cass, Union, Adams, and Ringgold Counties through the night. Reports of ping pong to golf ball size hail were numerous with these cells. One of the storms intensified as it moved through the Mt Ayr area. The storm dropped tennis ball size hail for about 10 minutes across the town, resulting in widespread damage to vehicles and buildings. Insurance claims from the town were near $10 million. The thunderstorms produced very heavy rainfall with rainfall rates in excess of 2 inches per hour at times. The heaviest rainfall occurred across southern Cass into northern Adams Counties, and extended east into Union County. The storms subsequently moved farther southeast with heavy rainfall pushing into Ringgold and parts of Decatur Counties. The band was about 20 miles wide and produced general rainfall of 2 to 4 inches. Flash flooding was reported with numerous roads closed by flowing water as 4 to 6 inches of rain fell in that area in under 2 hours. Spotty reports of 4 to 8 inches of rainfall were received. Flash flooding took place near Delphos in Ringgold County with 6 inches of flowing water over County Road J43. Flash flooding was also reported in eastern Adams County along U.S. Highway 34. Lightning caused a house fire in Ankeny as the leading edge of the morning storms moved into central Iowa. Firefighters were dispatched to the house at 1530 CST Saturday afternoon. Neighbors had called 911 to report fire and smoke coming from the home's roof. Flames were coming out the vents when firefighters arrived.

A cold front dropped southeast, producing severe weather on the 21st before it stalled out to the south of the state. As it lifted northward, deep moisture was transported into the upper Midwest as the remnants of a former eastern Pacific Hurricane was drawn north. The tropical moisture resulted in heavy rainfall over a large part of Iowa again on the 23rd, with some places in southern Minnesota receiving 6 to 10 inches of rain. The rainfall from Minnesota flowed down the Des Moines River and produced flooding as far south as Humboldt. The heavy rain that fell over Iowa during this event caused flooding farther south on the mainstem Des Moines, and on the South Fork Chariton River. The flooding caused some property damage and minor crop damage. Since much of the summer saw very elevated river levels, the flooding caused less damage than would be otherwise expected.

Wind gusts estimated at 60 MPH. This Monday afternoon and evening featured one of the last potent severe weather setups of the 2010 convective season in North Central Kansas, as moisture and instability increased along an east-west quasi-stationary surface front oriented near the Nebraska-Kansas state line. As storms first developed across the area at mid-afternoon, the mesoscale environment was ripe for organized severe weather with around 40 knots of deep-layer vertical wind shear, and 3000 J/kg mixed-layer CAPE. This environment supported at least brief supercell characteristics with a few afternoon and evening storms across North Central Kansas, although the bulk of severe weather focused north of the state line. One storm did result in a few reports of severe weather in northern Phillips County in the Long Island area, with estimated wind gusts to 60 MPH and quarter size hail. Note: The estimated wind gust of 52 knots is equivalent to 60 mph. Jewell County 9 N Esbon 25 0542CST North Branch 0547CST 0 0 0.00K 0.00K Hail (2.50)

A rogue elevated severe thunderstorm flared up just before sunrise on this Saturday morning, dropping a swath of large hail from quarter to tennis ball size across parts of northern Jewell County. The initial cluster of storms that eventually fueled this isolated hail event developed many hours earlier on late Friday evening in South Central Nebraska, about 100 miles to the north. Through the night, this loosely organized line of generally weak thunderstorms marched slowly south toward North Central Kansas, fed along the nose of a 40 knot southwesterly low level jet. While most-unstable CAPE values were quite weak through most of the night, an area of nearly 1000 j/kg MUCAPE eventually intersected the loosely organized line of storms prior to sunrise, in an area of maximized warm air advection on the nose of the low level jet. This rather abrupt increase in instability, working in concert with deep-layer vertical wind shear around 40 knots, likely resulted in the sudden storm intensification over northern Jewell County.

Two supercell thunderstorms left a destructive swath of very large hail across portions of the county. The swath of hail was approximately 5 miles wide and 15 miles long, stretching from northwest of Goddard, Kansas through the western and southern half of Wichita, Kansas to near Rose Hill, Kansas. Hail as large as softball and grapefruit size pounded roofs and cars along its path with over 35,000 claims turned into insurance agencies. The hail made roofs look like a war zone, with holes big enough for people to stick their heads through. Cars and golf courses were pot marked with large dents. Some of the hail came through roofs, including the terminal at the Mid Continent Airport in Wichita. Three commercial airliners were damaged and had to be towed to hangers for repairs. The National Weather Service in Wichita suffered damage to its vehicles, including one hail dent that was almost 10 inches across. One such hailstone 2 miles west of the National Weather Service office broke the state record for diameter, measuring 7.75 inches across (see separate entry).

Severe drought developed over a few counties near the Mississippi River, while moderate drought conditions persisted over most of the remainder of western Kentucky during the month of September. With the exception of a heavy rainfall event from the remnants of Tropical Storm Hermine, rainfall was practically non-existent in September. Hermine brought two to four inches of rain on the 9th and 10th to parts of southwest Kentucky. While this rainfall was very beneficial, it was the only significant rainfall during the month. Hermine greatly improved short-term rainfall deficits in parts of southwest Kentucky, but year-to-date rainfall deficits were still eight to twelve inches. Most of Hermine's rainfall missed northwest Kentucky, including the Owensboro and Henderson areas. By month's end, 88 percent of Kentucky topsoil was rated short or very short on moisture, and 89 percent of subsoil was rated as short or very short. Sixty-five percent of pasture land was rated as poor or very poor, which impacted hay crops. Bans on outdoor burning were imposed in various counties at various times, depending on the effects of former Tropical Storm Hermine. A state firefighter was injured while fighting a 12-acre woods fire in Livingston County. Crop harvests were well underway in September, but crop damage figures were not yet available. Preliminary estimates from farmers and agricultural extension agents were that corn crop yields would be down 30 to 50 percent in some areas, and soybean yields would be down 50 to 70 percent. Most of western Kentucky was still designated by the state of Kentucky as a drought management area because water supplies were down. In August, the governor of Kentucky sought a federal disaster declaration for west Kentucky due to substantial agricultural losses due to drought. Dry pastures and diminished stock ponds were problematic for livestock producers.

Tropical Storm Earl made landfall on the east coast of Nova Scotia during the mid morning of the 4th. The minimum surface pressure across the region with the storm was 989 mb. The storm brought sustained winds of 15 to 25 mph to the immediate Downeast coast during the early morning hours of the 4th while tracking east of the region. Wind gusts near the immediate coast generally ranged from 30 to 40 mph. A peak wind gust of 41 mph was reported at West Quoddy. There were no reports of wind related damage. Storm surge was not a factor. The storm also brought heavy rain to portions of the region. Rainfall totals of 1.50 to 3.00 inches were common across much of the region...with localized totals of 4.00 to 5.00 inches. However...the heavy rains fell after several weeks of dry conditions which had led to unusually low water levels on area rivers and brooks. Thus...although the heavy rain caused elevated water levels on small brooks and rivers...no river or brook flooding was reported. Minor street flooding was reported in the town of Machias...with one street temporarily closed.

The Maryland Department of the Environment issued a drought watch for the Maryland Eastern Shore except for Cecil County on September 9th. The Maryland Department of Natural Resources Forest Service strongly encouraged homeowners not to do any outdoor burning until the state received significant steady rainfall of one inch or more. The drought conditions were caused by the hottest summer on record in the state of Maryland as well as a drier than normal (about 80 percent of normal rainfall) summer. September 2010 was also warmer than normal (statewide average 1.9F higher than average) and until the last day of the month was also drier than normal. The heavy rain that fell on September 30th gave the state on average a wetter than normal September.

A slow moving frontal boundary with waves of low pressure along it produced heavy rain in Cecil County on September 30th and October 1st. Remnant moisture from Tropical Storm Nicole was entrained along the frontal boundary. The first wave of heavy rain during the morning of the 30th produced isolated flooding. Runoff from the heavy rain contributed to the minor tidal flooding around Charlestown later in the day on the 30th.

The combination of strong south to southeast winds during the day and evening on the 30th and periods of heavy rain downed trees, tree limbs and wires across the Eastern Shore, particularly in Cecil County. Peak wind gusts averaged 40 to 45 mph. The combination of the south winds and fresh water runoff also caused widespread minor tidal flooding with the late afternoon and evening high tide on the 30th. In Cecil County, many schools dismissed children early. About 3,000 homes and businesses lost power in and around Rising Sun during the late afternoon on the 30th. The combination of the tides and runoff caused minor tidal flooding along the North East River in Charlestown. The Northeast River overflowed into Charlestown Manor Beach. Flood waters surrounded a home on Conestoga Street and there was water on Shore Road. The evening high tide reached 4.38 feet above mean lower low water at Tolchester Beach (Kent County). Minor tidal flooding starts at 3.5 feet above mean lower low water while moderate tidal flooding starts at 4.5 feet above mean lower low water. The peak wind gust in Salisbury (Wicomico County) was 43 mph. The strong wind was caused by the pressure difference between a high pressure system off the Eastern Seaboard and a low pressure system that moved from North Carolina north into Pennsylvania during the day on the 30th. As the initial low pressure system weakened and the frontal boundary moved closer to the Eastern Shore, winds diminished overnight on the 30th.

With the exception of a heavy rainfall event from the remnants of Tropical Storm Hermine, rainfall was rather hard to come by in September. Hermine brought three to five inches of rain on the 9th and 10th to parts of southeast Missouri. While this rainfall was very beneficial, there was generally less than an inch the rest of the month. Hermine greatly improved short-term rainfall deficits, but year-to-date rainfall deficits were still 4 to 8 inches. By month's end, 32 percent of the Missouri cotton harvest was rated poor or very poor. Eighty-seven percent of pasture land in the extreme southeast corner of the state was rated as poor or very poor, which impacted hay crops. Crop harvests were well underway in September, but crop damage figures were not yet available. Unirrigated corn yields were expected to be a total failure in some places.

Thunderstorm wind gusts were measured at 58 mph by Asos at the Falls City airport at 743pm CDT. Winds were estimated at close to 65 mph in town which downed numerous tree limbs. Pea-size hail and over 3 inches of rain in an hour was also reported. The storm total in the Fall City area this evening was over 3 inches.

Thunderstorms developed by mid afternoon on Sept. 13 along and north of a warm front that had moved into east central Nebraska. The air mass south of the boundary was moderately unstable with temperatures in the mid to upper 80s and dew point temperatures around 70. Additional thunderstorms developed in this unstable air mass south of the front, several of which were supercells. One supercell, the right-mover of a storm that split in Jefferson county produced a brief tornado southwest of Fairbury. Meanwhile, another supercell produced a swath of wind damage as it tracked south-southeast from around Wahoo into the southeast corner of Nebraska. Especially hard hit from that particular storm was the area from southeast Saunders county into Cass and Otoe counties where winds were estimated by an assessment team from the NWS at 60 to 80 mph. Several semi-trucks were blown off of Interstate 80 in this area and almost 3,000 customers lost power due to significant damage to trees, power poles/lines, houses and other structures in that region. The Nebraska Emergency Management Agency estimated that preliminary estimates of damage to public infrastructure totaled more than $2.7 million from the storms and 7 counties applied for federal disaster aid. Note: The measured wind gust of 50 knots is equivalent to 58 mph.

This Monday afternoon and evening featured the last fairly widespread severe weather event of the 2010 convective season in South Central Nebraska, as moisture and instability increased along an east-west quasi-stationary surface front aligned near the Nebraska-Kansas state line. All severe weather events involved large hail and focused south of Interstate 80. As storms first developed across the area at mid-afternoon, the mesoscale environment was ripe for organized severe weather with around 40 knots of deep-layer vertical wind shear, and 3000 J/kg mixed-layer CAPE. This environment supported at least brief supercell structures, with the bulk of severe hail reports associated with a few discrete storms. Most notable was a storm that pounded parts of Kearney, Phelps, and Harlan Counties with very large hail up to baseball size. Considerable hail damage occurred in the community of Wilcox. Elsewhere across the area, hail up to golf ball size was reported near Pauline in southeast Adams County.

NEZ062-063 Hall - Hamilton 15 0155CST 0348CST 0 0 0.00K 0.00K High Wind

The pre-dawn hours on this Wednesday morning featured a somewhat unusual high-wind event that focused across the Interstate 80 corridor, with gusts to at least 60 MPH measured at both the Grand Island and Aurora airports. Gusty winds of 40- 60 MPH lasted for at least a few hours in some areas, but were not associated with the leading edge of intense thunderstorm outflow or intense precipitation. Instead, these winds occurred along the far northern edge of an area of fairly light showers and weak thunderstorms, well to the north of an area of strong thunderstorms and heavy rain in North Central Kansas. These winds were likely attributed to rain falling into dry air aloft, evaporating into the dry air, and causing it to sink rapidly to the surface. Sporadic wind damage reports included a destroyed tent on the Husker Harvest Days grounds west of Grand Island, delaying the opening of the nation's largest totally irrigated working farm show.

September started with a drought watch in effect for Morris County. The New Jersey Department of Environmental Protection on September 8th then extended the drought watch throughout the entire state. The Department of Environmental Protection asked all state residents to voluntarily conserve water. The hot and dry summer taxed reservoir stream and groundwater levels. Shallow groundwater (private) wells were also starting to show stress. Franklin Township in Somerset County declared a water emergency on the 16th and placed a 90 day ban on filling pools and washing cars and other outside surfaces and also limited the amount of lawn watering. Another effect of the drought was the re- emergence of the brown tide in Barnegat Bay. The extremely dry conditions with little freshwater runoff into the bay raised salinity levels. This set the explosion of billions of micro-organisms in the bay. These organisms interfere with shellfish organs and literally make them starve to death. September was another unseasonably warm month in New Jersey. Statewide it was the 4th warmest September on record since 1895 with an average temperature of 69.2 degrees. Because of the heavy rain on the last day of the month, September averaged closer to normal rainfall. It was the 7th warmest (71.0 degrees) September on record at the Atlantic City International Airport and the warm season as a whole established a new record for the number of days that the maximum temperature reached or exceeded 90 degrees (46 days). It was the 6th warmest (70.8 degrees) September on record in Trenton (Mercer County) and Trenton set its own record of 90 degree days with 52 days.

A wet microburst associated with a severe thunderstorm caused considerable tree and some wind damage in Perth Amboy. The estimated maximum wind speed was about 80 mph and struck the historic district in the southeast part of Perth Amboy the hardest. About 15 to 20 homes and buildings were damaged. One family on Paterson Street had to be relocated because the roof over the front door of their home became detached. A state of emergency was declared and only emergency responders were permitted to travel through the southeast part of the city. It was lifted on the 18th when most streets were passable again. There was a measured wind gust of 73 mph within Perth Amboy. A funnel cloud also passed across the city, but did not touch down. Damage from the microburst occurred in an area bounded by 2nd Street to the west, Smith Street to the north, and the waterfront on the east and south. The most concentrated damage occurred on Water, Market and High Streets. Snapped trees and tree branches were the prevalent damage type, but roof and chimney damage also occurred in several locations. A couple of cars were also damaged by downed trees. No homes experienced significant structural damage, but several garages were badly damaged by either the winds themselves or collaterally from flying and/or falling debris. One minor injury due to flying debris occurred along First Street. The worst damage was located in a two-block area bounded by Second Street, Gordon Street, Madison Avenue and Lewis Street. Several large trees and numerous power lines were blown down, and structural damage occurred to several garages. Numerous houses in this area suffered roof damage, mainly in the form of lost shingles and damaged or destroyed chimneys. Several homes had sections of roofs torn away. A roof was also torn from one industrial building along Second Street, portions of which were transported several blocks away. Extensive tree damage also occurred in and near Bayview Park. Personnel from the city of Perth Amboy and the city of Woodbridge worked through the night to clean up the storm debris.

Note: The estimated wind gust of 70 knots is equivalent to 81 mph.

A squall line of strong to severe thunderstorms moved across most of New Jersey during the late afternoon and early evening on the 16th. At the same time, a warm front was advancing north through the state. The added shear or change of wind speed and direction with height near the proximity of this front caused most of the severe thunderstorms as well as one tornado in Ocean County. About 50,000 homes and businesses lost power, many of them in Middlesex, Monmouth and Ocean Counties. All power was restored by the evening of the 17th. Many shore high school football games were postponed because of the dangerous weather. Note: The estimated wind gust of 52 knots is equivalent to 60 mph.

Strong south to southeast winds during the day and evening on the 30th and periods of rain downed weak trees, tree limbs and wires in central and southern New Jersey, especially in the southwest part of the state. Peak wind gusts averaged 40 to 45 mph, except they reached 50 to 55 mph along the immediate coast of Monmouth and Ocean Counties. The combination of the southeast winds and fresh water runoff also caused widespread minor tidal flooding during the evening high tide along the tidal sections of the Delaware River and its tributaries on the 30th. About 10,000 homes and businesses lost power in the southern part of the state, with most of the outages concentrated in Cumberland, Salem and Gloucester Counties. Weak trees and tree limbs were knocked down in Alloway Township (Salem County) and in Deptford, Elk and Washington Townships in Gloucester County. Peak wind gusts included 55 mph at Point Pleasant (Ocean County), 51 mph in Keansburg (Monmouth County), 50 mph in Barnegat (Ocean County), 43 mph in Trenton (Mercer County) and 40 mph at the Atlantic City International Airport (Atlantic County) and Cape May (Cape May County). The early evening high tide reached 8.59 feet above mean lower low water in Philadelphia. Minor tidal flooding starts at 8.2 feet above mean lower low water while moderate tidal flooding starts at 9.2 feet above mean lower low water. The afternoon high tide reached 7.60 feet above mean lower low water at Reedy Point (New Castle County Delaware). Minor tidal flooding starts at 7.2 feet above mean lower low water while moderate tidal flooding starts at 8.2 feet above mean lower low water. The strong wind was caused by the pressure difference between a high pressure system off the Eastern Seaboard and a low pressure system that moved from North Carolina north into Pennsylvania during the day on the 30th. As the initial low pressure system weakened and the frontal boundary moved closer to New Jersey, winds diminished overnight on the 30th.

Flash flooding occurred along CR4990. A damage survey found that several arroyos flow from the higher terrain to the south of the road northward into the San Juan River. Though radar indicates that the brunt of the precipitation fell to the south of the road, the road became impassible at several locations as there was evidence that a large swath of mud and water flowed across the road, underneath some nearby raised residences. Since these homes were elevated, they did not receive any damage inside. The storm moved east-northeast near the intersection of CR4990 and CR4550, just south of Blanco, where there was some evidence that high waters flowed there recently.

Isolated strong to severe thunderstorms marched eastward across northern San Juan County during the afternoon of the 8th.

A cold front stalled across across central and eastern portions of North Carolina on the 25th of September. In the mid and upper levels of the atmosphere, a closed low pressure was digging across western Tennessee. The slow moving upper low would cause a series of low pressure waves to ride along the stalled frontal zone, while also advecting copious amounts of tropical moisture into the region. Central North Carolina received 2 to 5 inches of widespread rainfall on the 26th, but because of ongoing severe drought conditions, no flooding occurred. After a lull on the 27th and 28th, a second upper level low developed over western Tennessee once again. This acted to pull the stationary boundary and moisture conveyor back to the west, as well as pick up remnants of Tropical Storm Nicole. Central North Carolina saw an additional 3 to 6 inches on the 29th and 30th. The combined rainfall of 6 to 10 inches from the 26th through the 30th of September resulted in flashing flooding and minor river flooding.

On the 25th of September, a powerful area of low pressure was located over the southeastern U.S. Several weak centers of low pressure formed over the Gulf Coast area from the 26th to 28th and pushed northeast along a stationary boundary bringing very high moisture from the Gulf and Atlantic Ocean. This deep moisture was pulled northward into the piedmont of the Carolinas and Virginia. A strong southeast flow developed in the low levels of the atmosphere and initiated a significant upslope component formed as well, with the highest amounts of rain falling along and east of the Blue Ridge. Storm total rainfall was greatest along the crest of the Blue Ridge and east into the foothills. This region received three to five inches. A second around of rain began in earnest during the evening hours of the 29th as remains from Tropical Storm Nicole moved across North Carolina and eastern Virginia. Rainfall rates increased during the overnight hours with the heaviest amounts falling from the Blue Ridge eastward. There was a much sharper western cutoff to this precipitation pattern, with very little falling west of the Blue Ridge and heavy rains to the east. The heaviest rains were concentrated from Rockingham County, NC through Henry County, VA and into southern Franklin County, VA. Rainfall rates of 1.0 to 1.5 inches per hour occurred in the same region that received the heaviest amounts rain on the 26th through the 28th. This prompted flash flood within this region. Precipitation continued through much of the 30th as the remains of Nicole shifted northward. Three day rainfall totals exceeded ten inches over parts of Henry County with widespread three to five inch totals noted east of the crest of the Blue Ridge.

Flooding observed from SR211, south to Redbug Road, with three feet of water on the road. There was a car in a sinkhole at the 900 block of Copas Road. A nearly continuous feed of tropical moisture, combined with a series of upper level low pressure systems, produced record rainfall over the region. Many areas received over 20 inches of rainfall over a four day period. Rainfall accumulations led to significant flooding that included the closure of dozens of roadways. Many low lying bridges were overtopped and swift waters led to numerous road scours and closings. Prior to the record rainfall, September 2010 was the third driest on record dating back to 1871. The rain at the end of the month made this September the second wettest on record. The impacts of the rain were greatest in the Cape Fear region. In Brunswick County, over 50 roads and 6 bridges were closed, with 17 roads needing repair. In New Hanover county, there were 137 homes impacted, and 34 buildings at the University of North Carolina at Wilmington sustained water damage.

NWS storm survey found a tornado damage path that began near the intersection of Conley Rd and Fisher Davis Rd. Several trees were snapped off or uprooted at this location, and a car port was detached and thrown from a home. Siding and flashing were also torn off this home. The tornado continued to produce intermittent damage as it moved north northeast, roughly paralleling Conley Rd. Part of the roof and some siding was blown off a home just south of Bennett Rd, with debris scattered several hundred yards away. Multiple trees were snapped off or uprooted and part of the roof was peeled off a home north of Bennett Rd. A car port was blown several hundred yards at this location and the doors were blown in on a garage, causing one wall of the garage to collapse. As the tornado continued north northeast, multiple trees were snapped off or uprooted, with trees falling on several homes. A horse trailer also was blown over and several homes received minor structural damage before the tornado lifted near the intersection of Conley Rd and Jeeter Carswell Rd.

Low pressure moved northeast, across the western Carolinas and northeast Georgia during the afternoon and evening hours. Along with quite a bit of rain, a few severe storms affected the region, one of which produced an EF1 tornado in Burke County.

These thunderstorms produced damaging straight line winds that caused numerous toppled and snapped trees as well as downed power lines that left an estimated 100 thousand people without power across the region. In Ohio, the hardest hit counties were Harrison and Jefferson, where a tractor trailer was overturned on Route 43. Allegheny and Westmoreland counties in western Pennsylvania were also hit hard.

A tornado touched down in Wayne County two miles southwest of downtown Wooster around 5:26 pm. This tornado strengthened to EF2 intensity and continued on the ground for over 11 miles before finally lifting two miles west of Dalton. Extensive damage occurred along the damage path with dozens of homes and buildings damaged. After the initial touchdown, the tornado quickly intensified to an EF2 as it continued on the ground to the east northeast. The tornado crossed Prairie Lane and Timken Road and then moved across St. Mary's Cemetery. Damage at the cemetery was extensive with 80 of 81 large trees knocked down and over two hundred gravestones broken or toppled. From the cemetery, the tornado crossed Madison Avenue and moved across the Ohio Agricultural Research and Development Center (OARDC). Significant damage occurred on the OADRC campus with several buildings severely damaged. A laboratory in one the buildings was destroyed. Two historic homes on the property sustained significant roof damage and several greenhouses were destroyed. Two barns and a machine shop were also leveled. The 102 year old Secrest Arboretum on the campus lost over 800 trees and many research projects were damaged or destroyed. The tornado tossed and destroyed several vehicles and a lot of farm machinery was also damaged or destroyed. From the OARDC campus, the tornado continued east along Secrest Road damaging or destroying several homes and buildings. The tornado weakened to EF1 intensity as it crossed Sylvan Road and to an EF0 as it crossed Barnard Road. The tornado then remained either an EF0 or EF1 until it lifted near the intersection of Kidron Road and Old Lincoln Way just west of Dalton. A total of nine homes were either destroyed or sustained major damage. Another 90 homes sustained lesser amounts of damage. In addition, at least 50 barns, garages and other outbuildings were damaged of destroyed. Thousands of trees were also toppled along the damage path which was up to 150 yards in width. Twenty eight utility poles were knocked down in Wooster alone and high tension transmission lines were also torn down by the tornado. The downed transmission lines affected four substations and resulted in around a third of Wayne County loosing power right after the tornado. The OARDC campus was closed for over a week and two local school districts had to close on September 17th because of the power outages. Only one very minor injury was reported.

OHIO, Southeast

A cold front, in tandem with strong mid and upper level forcing, produced a severe weather outbreak in southeast Ohio into extreme western West Virginia during the late afternoon and evening of Thursday the 16th. The setup featured a 45 knot mid level flow and a 95 knot upper level jet. Matter of fact, a larger area of showers, associated with a warm front, had moved across southeast Ohio and West Virginia during the morning and midday hours. This kept the surface based instability at a minimum. However, new cells formed further west during the mid afternoon over western Ohio. It was this new cluster of convection that would intensify due to the strong mid and upper level dynamics. Several of the new cells formed and intensified on the southern or southwestern flank of the overall larger area of showers and thunderstorms. This area of convection stretched further to the northeast into eastern Ohio and western Pennsylvania. This allowed an unimpeded low level moisture inflow into the new development. Surface dew points ahead of the cold front reached into the mid 60s. Most of the severe thunderstorms exhibited strong rotation, resulting in the spawning of 5 tornadoes. Four of these 5 tornadoes were in Ohio. One of the 4 Ohio tornadoes crossed from Fairfield County into western Perry County. Another 1 of the 4 crossed from Perry into northwestern Morgan County. One tornado patch was solely in western Athens County. The damage continued another 10 miles in Athens County from a strong rear flank downdraft. Finally, the last of the 4 tornadoes in Ohio crossed the Ohio River from northeastern Meigs County into southern Wood County in West Virginia. From storm surveys, this was the strongest tornado. The last tornado path in this outbreak was solely in western West Virginia. Luckily, there were no fatalities in southeastern Ohio. However, there was one death on the West Virginia side of the Ohio River.

Shower and thunderstorm development on the northern periphery of the remnants of Tropical Storm Hermine affected portions of southeast Oklahoma beginning on September 7th, while the center was still over central Texas. Light to moderate rain continued through the 8th over much of the region and then became much heavier as the center of the storm moved from southwest Oklahoma into northeast Oklahoma late on the 8th and during the early morning hours of the 9th. The heaviest rainfall totals occurred just east of the storm track. Rainfall rates of over two inches per hour and rainfall totals of eight to fourteen inches across east central OK and northwest AR led to widespread flash flooding during the morning hours of the 9th. The heaviest swath of rain occurred across southern McIntosh, northern Pittsburg, southern Muskogee, Haskell, Sequoyah, and southern Adair Counties in eastern Oklahoma, and some of the worst flooding occurred in these areas. The following locations received in excess of seven inches of rain during the event, much of which fell during a several hour period during the early morning hours of the 9th: 13.42 inches in Whitefield in Haskell County, 11.25 inches in Stigler in Haskell County, 10.41 inches in Sallisaw in Sequoyah County, 10.35 inches in Eufaula in McIntosh County, 9.60 inches at R.S.

Thunderstorms developed during the morning hours, with some flooding reported over parts of Cleveland county. A couple of highways had to be closed near Etowah due to high water, but were opened back up a few hours later. Later that afternoon, strong heating, a very moist air mass, and support from a weak eastward moving mid-level disturbance contributed to the development of additional thunderstorms over Oklahoma. These slow-moving thunderstorms produced very heavy rain and gusty winds. Most of the gusts reported were less than 50 mph. However, a few gusts exceeded severe limits, with gusts of 60 to 70 mph reported. Minor damage was reported in Garfield county. The thunderstorms decreased in intensity and coverage with the loss of daytime heating. Note: The estimated wind gust of 61 knots is equivalent to 70 mph.

Many smaller streams and creeks exceeded bankfull levels and minor flooding was observed. A slow moving north-south oriented frontal boundary and surges of tropical moisture along this boundary produced excessive rainfall in southeastern Pennsylvania. The deep tropical moisture connection was associated with the remnants of Tropical Storm Nicole. Widespread heavy rainfall amounts on the order of 3 to 6 inches were recorded over a 48 hour period, with isolated amounts as high as 8 inches. This was a record rain event over most of the area and resulted in significant flooding and flash flooding.

Thunderstorm winds estimated near 60 mph knocked down numerous trees in Windsor Township near Red Lion.

A complex weather pattern triggered two minor convective episodes during the mid-morning and late evening hours. The morning severe weather threat was characterized by strongly veered low level wind shear along and north of a warm front that lifted slowly north across the lower Susquehanna Valley. Despite meager instability, rich tropical moisture and the strong low level wind shear fueled fast-moving, shallow rotating convective elements that evolved rapidly from near the Chesapeake Bay north into southeast Pennsylvania. The second area of severe weather occurred along and ahead of a strong cold front that pushed through eastern Pennsylvania during the late evening. Weak instability combined with very strong unidirectional winds to produce a few broken lines of severe thunderstorms. Note: The estimated wind gust of 50 knots is equivalent to 58 mph.

September started with a drought watch in effect for Carbon and Monroe Counties. The Pennsylvania Department of Environmental Protection on September 16th upgraded the Poconos to a drought warning as well as most of the rest of Eastern Pennsylvania except for Chester and Delaware Counties which were placed in a drought watch. A drought warning asks residents to reduce water consumption by 10 to 15 percent. Water suppliers need to monitor supplies and update drought contingency plans. A drought watch calls for a 5 percent reduction in non-essential water use and also puts large water consumers on notice to begin planning for the possibility of reduced water supplies. The Department of Agriculture declared most of Eastern Pennsylvania a drought disaster and made farmers throughout Eastern Pennsylvania eligible to apply for low interest loans to help recover from crop losses. A couple of municipalities issued their own warnings. East Stroudsburg (Monroe County) issued a drought warning on September 1st and asked residents to voluntarily cut back on non-essential water use. This was upgraded to a drought emergency on September 20th when its Middle Smithfield Township reservoir fell to about 50 percent of capacity. All non- essential water use from lawn watering to car washing were banned as was the suspension of fire department pump testing and water training, Sellersville (Bucks County) issued a drought warning after its reservoir fell down to one third of capacity and asked residents to cut water usage by ten percent.

The combination of strong south to southeast winds during the day and evening on the 30th and periods of heavy rain downed weak trees, tree limbs and wires in Southeastern Pennsylvania. An automobile accident with a downed tree in Chester County claimed the life of one man. PECO Energy reported that 119,000 of its customers lost power. Peak wind gusts averaged 40 to 45 mph. The combination of the southeast winds and fresh water runoff also caused widespread minor tidal flooding during the evening high tide along the tidal sections of the Delaware River and its tributaries on the 30th. In Chester County, a 47-year-old man was killed after his Sports Utility Vehicle spun off the Pennsylvania Turnpike and slammed into a downed tree. Downed trees blocked roadways in Coatesville and East Bradford. Downed wires closed a roadway on West Chester. In Delaware County, downed trees were reported in Havertown. in Philadelphia, a downed tree forced SEPTA to suspend service on one commuter rail line on the evening of the 30th. Delays at Philadelphia International Airport reached up to two hours because of the wind and rain. The early evening high tide reached 8.59 feet above mean lower low water in Philadelphia. Minor tidal flooding starts at 8.2 feet above mean lower low water while moderate tidal flooding starts at 9.2 feet above mean lower low water. Peak wind gusts included 44 mph at the Philadelphia International Airport. The strong wind was caused by the pressure difference between a high pressure system off the Eastern Seaboard and a low pressure system that moved from North Carolina north into Pennsylvania during the day on the 30th. As the initial low pressure system weakened and the frontal boundary moved closer to New Jersey, winds diminished overnight on the 30th.

A few breaks in the cloud cover allowed CAPE values to reach 2000 J/kg before a low level jet and shortwave kicked off showers and thunderstorms. Storms initially became heavy rain producers before crossing the warm front. As thunderstorms crossed the warm front they encountered greater shear allowing them to become severe with signs of rotation.

Below normal rainfall fell during the month of September across much of West Tennessee. Memphis International Airport only received 0.14 inches of rain the entire month of September. The lack of rainfall expanded severe (D2) drought conditions into extreme portions of Northwest Tennessee. The biggest impact from the drought was on agriculture as many crops suffered due to the lack of rainfall. Hydrological concerns started to become an issue by the end of the month as many lake and river levels dropped. Burning permits were required due to the drought. A few wildfires occurred as a result of the dry conditions.

Victoria County 5 N Telferner 07 0809CST 0 0 0.00K 0.00K Flash Flood 4 NW Inez Heavy rain caused flooding along Benbow Road near Inez. Tropical Depression Hermine was a unique storm in that it formed as a result of the remnants of Tropical Depression number eleven in the Pacific crossing into the Southwest Gulf of Mexico on Sunday September 5, 2010. Hermine quickly gained strength becoming a strong tropical storm with winds of 60 mph in just 15 hours, and made landfall in northeast Mexico exactly 24 hours after it formed on Monday evening, September 6. The tropical storm then turned northward and moved quickly across south Texas into the Texas Hill Country on Tuesday September 7, bringing torrential rainfall, damaging winds and high tides. The corridor of strongest winds spanned an area along the South Texas coast from near Brownsville to San Antonio. Wind gusts between 50 and 70 mph were reported along the track. Damage was confined primarily to trees, signs, and metal buildings. Hardest hit areas were the cities of Bishop and Orange Grove where the eyewall tracked directly overhead. The storm knocked out power to approximately 20,000 customers in the Coastal Bend. The heaviest rains fell across the northeast Coastal Bend near Victoria and Seadrift where 4 to 8 inches were reported. Approximately 2 to 3 inches fell across the central Coastal Bend generally east of Highway 281. Although a few tornado warnings were issued based on radar signatures, there were no confirmed tornadoes. The strong winds and high surf caused tide levels to peak around 3.5 feet mean sea level along the barrier islands and near 3 feet mean sea level over the inland bays. This was about 2 feet above normal. The higher than normal tides resulted in minor flooding of area beaches, beach access roads and low areas around the inland bays. A portion of the Coastal Bend area's cotton production had not been harvested yet. Damages to the cotton crop yield occurred in Jim Wells and Nueces Counties. The potential monetary loss was in the millions of dollars. A majority of the area's sesame crop was damaged by the heavy rain and wind.

On Friday September 17th, 2010, Hurricane Karl made landfall over central Mexico near Veracruz nearly 600 miles south of Corpus Christi Texas. However, well to the north of Karl, a very moist tropical air mass resided and became the focus for a significant rainfall event. This rain event resulted in record flooding on Oso Creek in Corpus Christi, one flash flood fatality, and the flooding of numerous streets, homes, and vehicles along the immediate Texas coastline. On Sunday September 19th, a low pressure trough developed along the mid Texas coast and interacted with an upper level disturbance which focused the heaviest rainfall over Corpus Christi, Sinton, and Rockport. The heaviest rains occurred between 900 AM and 300 PM Sunday in which up to 7 inches of rain was recorded. These heavy rains caused widespread street flooding and road closures in Aransas, San Patricio, Nueces, and Kleberg Counties. Many homes in Corpus Christi were flooded, especially in the neighborhoods near the intersection of Holly and Greenwood. On Monday September 20th, another 1 to 2 inches of rainfall were recorded. Runoff from these heavy rains flowed into Oso Creek, which runs along the southwest edge of Corpus Christi. The only gaging site on Oso Creek, located on FM 763 about 2 miles west of town, recorded a rapid rise up to 28 feet on Sunday, before it stopped working.

Hermine would track to the northânorthwest at a steady 14 mph, with the center of circulation crossing the Rio Grande near Los Indios (Cameron County) at around midnight on Tuesday, September 7th. The center reached Harlingen at around 1 AM, Raymondville at around 2 AM, and progressed through the west portion of the King Ranch before exiting Deep South Texas near Falfurrias at around 5 AM. During that time, peak 1 minute sustained winds around the east periphery of the cyclone lessened only slightly, falling from 60 to 50 mph. A swath of damaging winds and flooding rains pounded Brownsville, Harlingen, and Raymondville as the eyewall of Hermine tracked along and east of Federal Highway 77 in Cameron and Willacy Counties. Peak wind gusts reached or exceeded 70 mph, causing widespread damage to trees and power lines. Rainfall of more than 3 inches in just a few hours flooded roads and farmland, especially in a small swath from northeast Cameron County to southern Willacy County. More than 250,000 residents were impacted by the core of Hermine during the middle of the night, making for a memorable end to the Labor Day weekend. The rapid movement and small core did not allow enough water to build up to a true storm surge in Cameron and Willacy County; tide departures peaked around 1.5 feet which produced run-up to the dune line and closed the county beach access points on South Padre Island to vehicular traffic. Hermine's near-hurricane force gust punch knocked down hundreds of tree limbs, tore off a number of roofs, blew down dozens of fences, and knocked power out to more than 55,000 area residents during the peak of the storm. In all, several millions of dollars in damage likely occurred to structures in the path of the core circulation of Hermine, including the inner eye wall and next level of core circulation on the east side of the center, which produced tropical storm force winds toward the coastline and into the Lower Texas Gulf waters. A federal emergency was declared for Cameron, Willacy, and Kenedy County based on initial impacts. Final damage statistics will be available later in autumn, 2010.

Cameron County 1 ESE Del Mar 19 0400CST 8 ENE Monte Grande 0930CST 0 0 50.00K 0.00K Heavy Rain

Heavy rainfall associated with a slow moving convergence zone slid east from what had been a train of 5 to 7 inches in 5 hours a bit farther west in Cameron County (Brownsville to San Benito). Between South Padre Island and Laguna Atascosa/Arroyo City, measured and estimated 3 to 5 inches of rain produced more nuisance flooding with up to 2 feet of water covering Padre Boulevard (Town of South Padre Island), a known poorly draining road which frequently experiences minor flooding. As of this writing, no significant damage was reported from the heavy rains in these areas.

Cameron County 1 SSE Villa Nueva 19 0500CST 1 N Villa Cavazos 1100CST 0 0 5.00M 0.00K Flash Flood

Upper level energy, low level convergence, and a possible overnight low level jet stream of extremely moisture laden air from the Gulf of Mexico produced prolonged torrential rains across south central Cameron County between 2 and 7 AM CST September 19th. The area shifted to the east and northeast between 7 and 8 AM CST, but not before dumping 5 to 7 inches of rain from Brownsville to San Benito and creating extensive flooding, impacting perhaps 100 or more structures, particularly in poorly draining areas. Impacts included: Up to 60 homes with water incursion in Colonia Galaxia in West Brownsville along Military Highway; several homes with water in them in the nearby subdivision of Quail Hollow; 37 residents evacuated from 9 flooded homes in Laureles (2.5 miles northwest of Los Fresnos); several homes flooded in the Green Valley Farms area along FM 510 near San Benito, including one location where 17 small mixed-breed dogs were rescued. Dozens of roads were closed temporarily or, in some cases, through the day. Notable closures included Paredes Line Road just north of Ruben Torres in Brownsville, Pablo Kisel near the Morrison Blvd. intersection in Brownsville, FM 1575 near/at State Highway 100 in Los Fresnos, and portions of State Highway 345 between San Benito and Rio Hondo. The Frontage Road near Price Road, along Federal Highway 77 in Brownsville had 2 to 3 feet of water well after the rains ended; notable poor draining roads in downtown Brownsville had similar high water. Though the rains ended between 8 and 9 AM CST, significant poor drainage flooding continued through 11 AM CST and pockets of flooding remained into the morning of September 20th. Dozen of pumps equipment were borrowed from Hidalgo County to assist with clearing water in poor drainage locations for the next few days.

TEXAS, South

Damage estimates will be into the $millions [final numbers available later this autumn]. Fortunately, no fatalities or injuries were reported as a direct consequence of the rains.

Deep tropical moisture, a series of upper level disturbances, and a pronounced low level jet streak have produced three days of on and off rainfall across the Rio Grande Valley and Deep South Texas. The big hitter occurred early Sunday, September 19th, when a persistent band of tropical rains set up camp between Brownsville and the east side of Harlingen, dumping 4 to 7 inches of rain in a 3 to 5 hour span and flooding a number of communities and dozens of roads especially between Brownsville and Los Fresnos, particularly those that drain poorly. Perhaps one hundred homes from Brownsville to San Benito were flooded, with dozens of residents evacuating to shelters for several days after the rains ended and a slow drainage began.

VIRGINIA, North

A corridor of tropical moisture travelled up the Atlantic seaboard, funnelling another area of low pressure that developed along the Carolina coastline through the Mid-Atlantic. Bands of heavy rain began to rapidly move into northern Virginia just after midnight on Thursday morning, September 30. After the initial low pressure passed north of the area late Thursday morning after producing up to 5 inches of rain and numerous reports of flash flooding across portions of northern Virginia, a brief lull in precipitation occurred Thursday afternoon, before the remnant circulation of once Tropical Storm Nicole moved up the Delmarva Peninsula, reinvigorating heavy rainfall. Storm total rainfall exceeded 8 inches across many areas. Hundreds of roads were closed due to high water across the area, and high water rescues and roadway washouts were frequent. There were no reported injuries or deaths. From a historical perspective, Washington Reagan National Airportâs 4.66" and Washington Dulles International Airportsâ 4.74" on Sep 30 were both the third highest daily rainfall amounts ever recorded in the month of September.

On the 25th of September, a powerful area of low pressure was located over the southeastern U.S. Several weak centers of low pressure formed over the Gulf Coast area from the 26th to 28th and pushed northeast along a stationary boundary bringing very high moisture from the Gulf and Atlantic Ocean. This deep moisture was pulled northward into the piedmont of the Carolinas and Virginia. A strong southeast flow developed in the low levels of the atmosphere and initiated a significant upslope component formed as well, with the highest amounts of rain falling along and east of the Blue Ridge. Storm total rainfall was greatest along the crest of the Blue Ridge and east into the foothills. This region received three to five inches. A second around of rain began in earnest during the evening hours of the 29th as remains from Tropical Storm Nicole moved across North Carolina and eastern Virginia. Rainfall rates increased during the overnight hours with the heaviest amounts falling from the Blue Ridge eastward. There was a much sharper western cutoff to this precipitation pattern, with very little falling west of the Blue Ridge and heavy rains to the east. The heaviest rains were concentrated from Rockingham County, NC through Henry County, VA and into southern Franklin County, VA. Rainfall rates of 1.0 to 1.5 inches per hour occurred in the same region that received the heaviest amounts rain on the 26th through the 28th. This prompted flash flooding within this region. Precipitation continued through much of the 30th as the remains of Nicole shifted northward. Three day rainfall totals exceeded ten inches over parts of Henry County with widespread three to five inch totals noted east of the crest of the Blue Ridge.

Trees were blown down along Road Run. A cold front, in tandem with strong mid and upper level forcing, produced a severe weather outbreak in southeast Ohio into extreme western West Virginia during the late afternoon and evening of Thursday the 16th. The setup featured a 45 knot mid level flow and a 95 knot upper level jet. Matter of fact, a larger area of showers, associated with a warm front, had moved across southeast Ohio and West Virginia during the morning and midday hours. This kept the surface based instability at a minimum. However, new cells formed further west during the mid afternoon over western Ohio. It was this new cluster of convection that would intensify due to the strong mid and upper level dynamics. Several of the new cells formed and intensified on the southern or southwestern flank of the overall larger area of showers and thunderstorms. This area of convection stretched further to the northeast into eastern Ohio and western Pennsylvania. This allowed an unimpeded low level moisture inflow into the new development. Surface dew points ahead of the cold front reached into the mid 60s. Most of the severe thunderstorms exhibited strong rotation, resulting in the spawning of 5 tornadoes. Four of these 5 tornadoes were in southeast Ohio. One of the 4 Ohio tornadoes crossed from Fairfield County into western Perry County. Another 1 of the 4 crossed from Perry into northwestern Morgan County. One tornado patch was solely in Athens County. Finally, the last of the 4 tornadoes in Ohio crossed the Ohio River from northeastern Meigs County into southern Wood County in West Virginia. This tornado was the strongest and resulted in a fatality on the West Virginia side of the Ohio River. The last direct death from a tornado in West Virginnia was back in June of 1982. Finally, the last short tornado path in this outbreak was solely in western West Virginia, located in Wirt County. Note: The estimated wind gust of 50 knots is equivalent to 58 mph.

An excessive rainfall event, with amounts of 3 to 6 inches, occurred across parts of central and northeast Wisconsin starting on the evening of September 22 and lasting through the morning hours of September 23. The initial band of heavy rain formed along a warm front that extended across north-central Wisconsin. Additional rains were a result of a cold front that moved across the state on September 23. The heaviest rain fell over the central part of the state where many locations received more than 5 inches. This led to flash flooding, as well as areal and moderate to major river flooding across parts of central Wisconsin. A new record stage was established on the Yellow River at Babcock in Wood County.

A strong cold front swept across Wisconsin, being driven by an amplifying short wave trough moving east from the Plains, that produced a strong area of low pressure north of Lake Superior. The front interacted with a warm and unstable air mass, with CAPE values between 1500 J/kg and 2000 J/kg, bringing severe thunderstorms to southern Wisconsin in the late afternoon and early evening hours. Strong deep layer shear led to the development of a line of thunderstorms with damaging wind gusts. Heavy rain with the thunderstorms produced 1 to 2 inch per hour rainfall amounts that briefly flooded streets and parking lots, especially on the southwest side of Madison, Verona and Fitchburg in Dane County. The heavy downpours and lightning forced officials to cancel a cross country meet in DeForest, also in Dane County. There were also a few reports of near-severe nickel-sized hail.

Early-morning, elevated thunderstorms developed on the nose of a 40-45 knot 850 mb jet under an expansive area of upper level divergence that aided the mid-level warm air advection. The thunderstorms developed to the north of a surface warm front that stretched across Iowa into northern Illinois, as the strong low level jet impinged on this front. The elevated thunderstorms produced showers of pea to dime-sized hail, with larger stones ranging from 1 inch to 1.75 inches in diameter.

A closed mid to upper-level low tracking across the northern U.S. took an associated surface low from the Dakotas, to Lake Superior and into southern Canada. The tight pressure gradient around this system produced strong winds across southern Wisconsin during the day. Wind gusts reached 40 to 50 mph (35 to 44 knots) in many locations. An 80 year-old Wauwatosa (Milwaukee County) man was killed in his back yard when a tree limb, estimated to weigh 1000 pounds, struck him after being blown down by the strong winds. The limb knocked the man's garage off its foundation. The highest measured wind gust reported in southern Wisconsin was 55 mph (48 knots) measured just southeast of downtown Pewaukee in Waukesha County.

A strong cold front was slowly sagging through southern Wisconsin during the early morning hours of September 18th. Mid- level warm advection and frontogenesis ahead of a short wave moving through the region created forcing and elevated instability, as well as strong effective deep layer shear of 40 to 50 knots, that generated elevated thunderstorms behind the surface cold front. The thunderstorms produced hail showers, turning the ground white, with hail stones up to 1 inch in diameter.

A cold front moving through the region was the focus for development of a broken line of thunderstorms ahead of the front during the afternoon and evening. The combination of ascent with a short wave impulse passing over the region, daytime heating, low-level moisture inflow on a 40 knot west southwest low-level jet, and steep low to mid-level lapse rates produced severe thunderstorms with large hail and damaging wind gusts. Additionally, the storms produced a brief, EF0 tornado in Rock County, southeast of Janesville. Note: The estimated wind gust of 52 knots is equivalent to 60 mph.

A tight pressure gradient set up over Wisconsin as strong low pressure, located over western Nebraska on the morning of September 23rd, moved northeast to central Lake Superior on the morning of September 24th. Scattered showers that formed ahead of a trailing cold front in the early morning hours transferred momentum down to the surface from a 50 to 55 knot low level jet, located between 1,000 feet and 2,000 feet above ground level. This produced southwest wind gusts between 39 and 48 knots (45 mph and 55 mph) at a few locations in far Southeast Wisconsin. There were scattered reports of downed power lines due to broken tree branches falling on wires.

Columbia County Wisconsin Dells 24 1800CST Portage 30 0500CST 0 0 1.23M 200.00K Flood

The river at the gage in Portage was in flood from the evening of September 24th through the morning of September 30th, and reached a record flood level of 20.66 feet during the evening of Monday, September 27th. The old record crest at Portage was 20.50 feet on 09/14/1938. The flood waters threatened to break through a century-old earthen dike in the Civil Township of Caledonia. The waters seeped through the dike, but the dike did not fail. The potential levee failures caused voluntary evacuations and road closures along the river from the Dells to Portage. As it turned out, dozens of homes in the Blackhawk Park area just southeast of Portage were cut off when water depths reached a foot on the only road into the area. The Columbia County Emergency Management Director provided the following loss estimates: $1 M for seasonal and full-time residental homes, $100,000 for patching and reinforcing part of a 14-mile earthen berm/dike, $50,000 for gravel shoulder washouts, $75,000 to a wastwater treatment plant, and $200,000 to bottomland crops. It was postulated that damage was limited due to the fact that the flood waters rose slowly which reduced the erosional power of water. The EM Director also noted that the Wisconsin River levels in Portage were about a foot higher than that experienced in the Great Flood of 1993, while at Wisconsin Dells the 2010 level was about a foot lower than that experienced in 1993.

Even though heavy rains didn't fall in the surrounding area, record river levels occurred on the Wisconsin River near Portage. A potent, early-fall, storm brought waves of heavy rain to western and central Wisconsin, well upstream from Portage, beginning late on Wednesday, September 22nd and continuing into early Friday, September 24th. Two-day rainfall totals of 4 to 8 inches across the Wisconsin River basin over those parts of Wisconsin resulted in flooding in the river basin from Sauk County near the Wisconsin Dells downstream through Columbia County.

The Antelope Wildfire was first spotted on Tuesday afternoon, September 14, following a lightning strike which ignited an area of grass and sage on the northeast slope of Mount Washburn in Yellowstone National Park. Unseasonably warm temperatures coupled with dry and windy conditions doubled the size of the fire on Sunday, September 19. The northwest corner of the fire initially threatened the Tower Fall area but no closures were needed. Over the course of the next week, however, the Grand Loop Road was closed in the vicinity of Tower Fall due to the wildfire. Fire growth was consistent over the next week. A ridge of high pressure over the Great Basin allowed for near-record and record warmth from September 25-28. On Tuesday afternoon, September 28, the fire surged across the Yellowstone River and up a west-facing mountain slope and boosted the fire's size by 1,300 acres. The wildfire was responsible for scorching nearly 4,100 acres by the end of September. More information on the conclusion of this wildfire is contained in the October 2010 Storm Data publication.

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.
