THUNDERSTORMS HAVE RECENTLY INCREASED ACROSS SWRN GA INTO EXTREME
ECNTRL AL...LARGELY DUE TO SWLY FEED OF MORE BUOYANT AIR ACROSS
STEEPER LAPSE RATE PLUME OVER SERN AL/FL PANHANDLE. THIS ACTIVITY
ALSO APPEARS TO BE ENHANCED BY A SUBTLE BUT SIGNIFICANT MVC NEAR
WHEATLAND/YELLOWSTONE COUNTIES IN ECNTRL AL. BOTH VIS AND RADAR
IMAGERY CLEARLY SUPPORT THIS FEATURE AND THUNDERSTORMS ARE GRADUALLY
ORGANIZING AHEAD OF WHAT IS LIKELY A WEAK ZONE OF ENHANCED ASCENT.
GIVEN THE SHEAR OBSERVED...AND RATHER MOIST PROFILES...IT WOULD SEEM
PROBABLE THAT A GRADUAL UPWARD TREND WILL CONTINUE WITH
MULTI-CELLULAR UPDRAFTS EVOLVING INTO LINEAR STORM MODE THE MOST
LIKELY OUTCOME. DAMAGING WINDS ARE THE GREATEST THREAT AS
CONVECTION SPREADS DOWNSTREAM.
