VALID 102208Z - 110015Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 135, 136
CONTINUES.
SUMMARY...SEVERE WIND GUSTS AND LARGE HAIL ARE EXPECTED WITH
CONVECTION AS IT SPREADS SOUTHEAST THIS EVENING.
DISCUSSION...MID-LEVEL HEIGHTS ARE FALLING ACROSS THE MID SOUTH THIS
EVENING AS A 500MB SPEED MAX DIGS ACROSS EASTERN KS TOWARD NORTHERN
MS. LEFT-EXIT REGION OF THIS JET APPEARS PARTLY RESPONSIBLE FOR AN
EXPANDING CLUSTER OF THUNDERSTORMS ALONG THE COLD FRONT OVER WESTERN
TN. ADDITIONALLY, WHILE THE BOUNDARY-LAYER LAPSE RATES ARE QUITE
STEEP ACROSS MUCH OF THIS REGION, SURFACE TEMPERATURES ARE
CONSIDERABLY WARMER ACROSS NORTHERN MS INTO CENTRAL AL WHERE
READINGS ARE IN THE LOWER 80S. AS PROFILES COOL ALOFT, THE GREATEST
BUOYANCY SHOULD FOCUS ACROSS NORTHERN MS INTO NORTHERN AL. FRONTAL
CONVECTION MAY CONTINUE TO GROW UPSCALE DUE TO THE AFOREMENTIONED
EXIT REGION AND THERMODYNAMIC PROFILES FAVOR STRONG DOWNDRAFTS, IN
ADDITION TO LARGE HAIL. SEVERE STORMS SHOULD SPREAD ACROSS NORTHERN
MS AND NORTHERN AL THROUGH MID EVENING.
