...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF SE AL...GA...SC
AND NC...

...SE AL/GA/SC/SRN AND ERN NC...
WATER VAPOR IMAGERY CURRENTLY SHOWS A SYNOPTIC SCALE UPPER-LEVEL
TROUGH LOCATED ACROSS THE PLAINS AND MID MS VALLEY. AHEAD OF THE
TROUGH...A BAND OF MID-LEVEL MOISTURE EXTENDS FROM THE WRN GULF OF
MEXICO NEWD ACROSS THE SERN UNITED STATES. THIS MOISTURE IS
CO-LOCATED WITH THE STRONGER LARGE-SCALE ASCENT ASSOCIATED WITH THE
TROUGH AND IS SUPPORTING A WELL-DEVELOPED CONVECTIVE LINE FROM THE
WRN FL PANHANDLE NEWD INTO NRN GA. THE LINE IS LOCATED AHEAD OF A
COLD FRONT WITH MID 60 F SFC DEWPOINTS PRESENT ACROSS MOST OF
GA...SC AND SRN NC. THIS SHOULD SUSTAIN THE LINE OF THUNDERSTORMS
WITH THE STRONGER CONVECTION MOVING ENEWD ACROSS SC INTO SERN NC
OVERNIGHT.

LATEST OBJECTIVE ANALYSIS SHOWS A 100 KT MID-LEVEL JET EXTENDING
NEWD FROM THE LOWER MS VALLEY NEWD INTO THE OH VALLEY. THE MID-LEVEL
JET IS BROAD AND 50 KT OF FLOW EXISTS ACROSS MOST OF GA...SC AND NC
ATTM. ALTHOUGH INSTABILITY WILL REMAIN WEAK ACROSS THE REGION
TONIGHT...THE STRONG VERTICAL SHEAR SHOULD CONTINUE TO SUPPORT AN
ISOLATED SEVERE THREAT WITH THE LINE. WIND DAMAGE WOULD BE THE
PRIMARY THREAT ALTHOUGH A TORNADO CAN NOT BE RULED OUT. AS THE LINE
APPROACHES HIGHER SFC DEWPOINTS ACROSS ERN SC AND ERN
NC...REDEVELOPMENT OR ENHANCEMENT OF THE LINE MAY OCCUR LATE
TONIGHT.
