AREAS AFFECTED...SERN GA

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 302107Z - 302200Z

ISOLATED BRIEF DAMAGING WIND/TORNADO THREAT WILL EXIST IN SERN GA
THE NEXT HOUR OR SO...THOUGH THE THREAT APPEARS TOO LIMITED FOR A
WW.

PREFRONTAL LINE OF CONVECTION HAS SHIFTED EWD ACROSS MOST OF THE
CAROLINAS AND EXTENDS SWWD ACROSS SERN GA FROM NEAR SAV TO 35N TLH.
AHEAD OF THIS BOUNDARY...TEMPERATURES HAD WARMED INTO THE MID 70S
AND DEWPOINTS INTO THE MID 60S...RESULTING IN MLCAPES UP TO 1000
J/KG. DESPITE WEAK LAPSE RATES AND MOSTLY UNIDIRECTIONAL SWLY WIND
PROFILES...THE DEGREE OF INSTABILITY AND 30-40 KT DEEP LAYER SHEAR
WAS SUFFICIENT FOR WEAK MID LEVEL ROTATION IN ONE OR TWO STORMS.
THE ENVIRONMENT MAY SUPPORT A BRIEF WIND/TORNADO THREAT FOR THE NEXT
HOUR OR SO...BUT SHOULD WEAKEN AS THE STORMS SHIFT EWD AWAY FROM THE
STRONGER FORCING AND ENCOUNTER DECREASING INSTABILITY.
