The upper-level low stalled over Texas on the morning of the 15th and remained in place until the evening of the 16th. Thunderstorms brought flash flooding and sixteen tornadoes (11 F0's, 5 F1's, as defined by the Fujita Tornado Scale) to the affected area.

Most areas received six to fourteen inches of snowfall. A moist northeast upslope flow from Lake Superior enhanced snowfall amounts across Baraga and Marquette Counties where 18 to over 30 inches of snow fell. At the Marquette National Weather Service Forecast Office in Negaunee, Michigan, 33.1 inches of snowfall was recorded between 06Z on November 26 to 18Z on November 28, 2001. Due to the high water content of the snow, tree branches snapped and fell across power and telephone lines causing numerous outages. No deaths were reported. At least 5 minor injuries occurred due to traffic accidents.

The tornado traveled across southeastern Lamar County damaging or destroying a number of structures south and east of Kennedy. The tornado traveled on a northeast track moving into Fayette County at 11:07 am. Traveling northeast it went across western and northern sections of the city of Fayette doing serious damage to a number of structures. From the city of Fayette the tornado traveled across mostly rural areas damaging occasional structures and downing numerous trees and power lines. The tornado while still strong was weaker than it had been in southern Lamar County. The tornado crossed into Walker County at 11:41 am a little south-southwest of Carbon Hill before ending. Total path length has been estimated at 38.9 miles with a Fujita-scale rating of F3. The tornado began with F0 damage in Pickens County but strengthened to F3 intensity in southern Lamar County. It weakened some as it moved across Fayette County where the Fujita rating was an F2. Damage in Walker County was rated an F1 as the tornado dissipated. The path was 300 yards wide in Lamar County but estimated to have decreased to about 90 yards wide across much of Fayette County. Two people, a mother and her daughter, were killed in a double-wide mobile home in Lamar County just southwest of Kennedy and one person was injured. No deaths or injuries were reported in Pickens, Fayette or Walker counties.

All this is good news for museums as well as others that count on attendance. This past Sunday, June 6th marked the anniversary of the D-Day landing, but it was also the 79th anniversary of the birth of Organic Army Aviation. General Order number 98 was signed giving the Ground Forces their own aircraft, pilots and mechanics as part of their Tables of Organization and Equipment (TO&E). Each Artillery unit would be authorized two aircraft, two pilots and one mechanic. These crews would travel and live with the unit in the field and provide reconnaissance, target spotting, medical evacuation and a host of other services.

    VOLUME 17 WEATHER AND FORECASTING OCTOBER 2002 Recognition of Negative Mesoscale Factors for Severe-Weather Potential: A Case Study CHARLES A. DOSWELL III* NOAA/OAR/National Severe Storms Laboratory, Norman, Oklahoma DONALD V. B AKER NOAA/NWS Weather Forecast Of®ce, Lubbock, Texas CHARLIE A. LILES NOAA/NWS Weather Forecast Of®ce, Albuquerque, New Mexico (Manuscript received 2 November 2001, in ®nal form 23 April 2002) ABSTRACT The case of 7±8 June 1998 in eastern New Mexico and western Texas is used to illustrate the challenge of recognizing possible negative effects created by mesoscale processes. In this case, a region of cloud-covered cool air (which was associated with early thunderstorms) may have limited the tornadic potential of severe convection. Although the tornado potential in the synoptic situation was not highly portentous, supercell storms did eventually form, one of which was persistent for many hours. There were only relatively brief and weak tornadoes reported from this storm early in its life, despite its persistence as a long-lived supercell that produced a long swath of large hail. In this case, the development of thunderstorms east of the threat area early in the day maintained cloudiness that apparently inhibited the destabilization of the surface-based air mass over which the afternoon thunderstorms eventually moved. The persistent supercell formed on the dryline but overrode this mesoscale cool air mass relatively soon after it developed. It was able to persist as an elevated supercell despite the relatively stable near-surface air mass, but its tornadic production may have been limited by its interaction with this mesoscale feature.

The objective of this study is to identify and characterize iIntense windstorms during the last four decades in the U.S. Northeast are identified and characterizedand determine both the sources of cyclones responsible for these events and the manner in which those cyclones differ 10 from the cyclone climatology. The windstorm detection is based on using the spatial extent of locally extreme wind speeds at 100 m height from the ERA5 reanalysis database. During all the of the top 10 windstorms, wind speeds in excess of their local 99.9th percentile extend over at least one-third of land-based ERA5 grid cells in this high population density region of the U.S.. Maximum sustained wind speeds at 100 m during these windstorms range from 26 to over 43 ms-1, with wind speed return periods exceeding 6.5 to 106 years (considering the top 5% of grid cells 15 during each storm). Property damage associated with these storms, inflation adjusted to January 2020, ranges from $24 million to over $29 billion. Two of these windstorms are linked to decaying tropical cyclones, three are Alberta Clippers and the remaining storms are Colorado Lows.

Gary L. Achtemeier, Stanley Q. Kidder, and Robert W. Scott Climate and Meteorology Section Illinois State Water Survey Champaign, IL 61820 ABSTRACT The variational multivariate assimilation method described in a companion paper by Achtemeier and Ochs is applied to conventional and conventional plus satellite data. Ground-based and space-based meteorological data are weighted according to the respective "measurement" errors and blended into a data set that is a solution of numerical forms of the two nonlinear horizontal momentum equations, the hydrostatic equation, and an integrated continuity equation for a dry atmosphere. The analyses serve first, to evaluate the accuracy of the model, and second, to contrast the analyses with and without satellite data. Evaluation criteria measure the extent to which a) the assimilated fields satisfy the dynamical constraints, b) the assimilated fields depart from the observations, and c) the assimilated fields are judged to be realistic through c I pattern analysis. The last criterion requires that the signs, magnitudes, and patterns of the hypersensitive vertical velocity and local tendencies of the horizontal velocity components be physically consistent with respect to the larger scale weather systems.

  • MET 3502 Synoptic Meteorology
    MET 3502 Synoptic Meteorology Lecture 19: Life Cycle of the Mid-Latitude Cyclone and Forecasting Mid-Latitude Cyclone What is a mid-latitude cyclone? The mid-latitude cyclone is a synoptic scale low pressure system that has cyclonic (counter-clockwise in northern hemisphere) flow that is found in the middle latitudes (i.e., 30ºN-55ºN) IT IS NOT A HURRICANE OR TROPICAL STORM 1) There is a location (tropics vs. mid-latitudes) and size difference between hurricane and mid-latitude cyclone 2) Typical size of mid-latitude cyclone = 1500-5000km in diameter 3) Typical size of a hurricane or tropical storm = 200- 1000km in diameter Here is a picture of a typical mid-latitude cyclone and hurricane. Notice the size difference. How does the mid-latitude cyclone form? History: Polar front theory: developed by Univ. of Bergen in Norway after the end of World War I Norway Cyclone Model (NCM): About the structure and life cycle of mid-latitude cyclone Explained evolution of midlatitude cyclones in terms of surface patterns Suffered from lack of knowledge of upper atmospheric patterns Provided a good description of how surface patterns evolve, but couldn't explain why Classical Model 1. Background State: There is boundary between cP and mT airmass in mid-latitude (Baroclinic Zone). 2. Perturbation Stage: Along this boundary a counter-clockwise circulation can set up at the surface, which acts to take warm air up from the south and cold air down from the north. This is called cyclogenesis. Classical Model 3. Mature Stage: If the upper levels are favorable, then the mid- latitude cyclone will continue to develop and bring up mT air in the warm sector and bring down cP air in the cold sector.
