AREAS AFFECTED...SERN GA/SRN AND CNTRL SC

CONCERNING...TORNADO WATCH 899...

VALID 282258Z - 290030Z

THE SEVERE THREAT SHOULD CONTINUE ACROSS TORNADO WATCH 899 OVER THE
NEXT FEW HOURS. THE SEVERE THREAT MAY ALSO EXPAND NEWD INTO CNTRL SC
AS STRONG CELLS DRIFT NEWD LATE THIS AFTERNOON.

WATER VAPOR IMAGERY CURRENTLY SHOWS A SHORTWAVE TROUGH OVER ERN GA
EMBEDDED IN THE LARGER ERN US TROUGH. THIS FEATURE WILL CONTINUE TO
MOVE NEWD THROUGH EARLY THIS EVENING ALLOWING THE LARGE CLUSTER OF
STORMS OVER GA AND SRN SC TO EXPAND NWD. SFC DEWPOINTS DROP OFF
QUICKLY FROM THE MID 50S F INTO THE 40S F EAST OF INTERSTATE 95. AS
THE CONVECTION MOVES NEWD INTO THE COLUMBIA AREA...LARGE HAIL AND
ISOLATED WIND DAMAGE WILL BE POSSIBLE WITH THE STRONGER CELLS.
GRADUAL WEAKENING SHOULD OCCUR WITH THE STORMS THAT MOVE NEWD AND
ENCOUNTER THE WEAKER INSTABILITY ACROSS ERN SC.
