THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 407
CONTINUES.
SUMMARY...THE RISK FOR SEVERE WIND GUSTS MAY ACROSS AND SOUTHWEST
THROUGH SOUTH OF THE GREATER SAN ANTONIO VICINITY THROUGH MIDNIGHT-1
AM CDT.
DISCUSSION...COLD POOL PROPAGATION INTO THE I-35 CORRIDOR NEAR AND
SOUTH OF SAN ANTONIO HAS BEEN AT RATHER MODEST SPEEDS OF 20 KT OR
SO, AND PEAK 3-SECOND GUSTS ALONG THE GUST FRONT HAVE RECENTLY BEEN
MEASURED AROUND 40 KTS. HOWEVER, STRONGER 2-HOURLY SURFACE PRESSURE
RISES IN EXCESS OF 4 MB HAVE BECOME EVIDENT IN THE 04Z SURFACE
OBSERVATIONS AT UVALDE AND JUNCTION. ADDITIONALLY, THE MOST
VIGOROUS CONVECTION ONLY SLIGHTLY TRAILS THE GUST FRONT, AND IS
BECOMING BETTER ORGANIZED, WITH A MESO-BETA SCALE CYCLONIC
CIRCULATION NOW FORMING TO THE WEST OF SAN ANTONIO. THIS MAY BE
ACCOMPANIED BY STRENGTHENING WESTERLY REAR INFLOW AND DOWNDRAFTS,
AIDED BY HEAVY PRECIPITATION LOADING, NEAR AND TO THE SOUTHWEST
THROUGH SOUTH OF GREATER SAN ANTONIO THROUGH 05-06Z.
