AREAS AFFECTED...SRN GA/CENTRAL AND ERN FL PANHANDLE

CONCERNING...TORNADO WATCH 65...

VALID 082137Z - 082300Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 65 CONTINUES.

ISOLATED STRONGER CELLS PERSIST ACROSS PARTS OF TORNADO WATCH
65...WITH WEAK ROTATION EVIDENT. GIVEN THE SCHEDULED 08/23Z
EXPIRATION OF WW 65 AND THE POTENTIAL THAT THE THREAT MAY SPREAD A
BIT E OF THE CURRENT WATCH WITH TIME...WE ARE CONSIDERING A
REPLACEMENT TORNADO WATCH.

LATEST OBJECTIVE ANALYSES SHOW VERY LIMITED INSTABILITY E OF WW 65
INTO SERN GA/N FL...BUT STORMS CONTINUE SPREADING SLOWLY EWD -- WITH
A COUPLE OF STORMS NOW NEAR THE ERN EDGE OF THE WATCH. WHILE THE
INSTABILITY IS LACKING...SHEAR REMAINS FAVORABLE FOR SUPERCELLS
ACROSS THIS AREA...WHICH SUGGESTS THAT A FEW ORGANIZED CELLS -- AND
ASSOCIATED SEVERE/ISOLATED TORNADO THREAT -- MAY GRADUALLY EXPAND TO
INCLUDE AREAS JUST E OF THE WATCH. WE WILL CONTINUE TO MONITOR
CONVECTIVE EVOLUTION OVER THE NEXT HALF HOUR TO HOUR -- AND THE
ASSOCIATED POTENTIAL FOR A NEW/REPLACEMENT WW.
