AREAS AFFECTED...ERN FL PANHANDLE INTO SWRN GA

CONCERNING...TORNADO WATCH 776...

VALID 271857Z - 272100Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 776 CONTINUES.

MAIN CONVECTIVE BAND CONTINUES MOVING EWD ACROSS THE ERN GULF/SERN
CONUS...WITH SOMEWHAT STRONGER/MORE CELLULAR CONVECTION FROM SWRN GA
SWD. EVEN ACROSS THIS REGION HOWEVER...WEAK INSTABILITY -- AS
INDICATED BY THE LACK OF INLAND LIGHTNING ATTM -- CONTINUES TO
HINDER THE DEVELOPMENT OF ISOLATED/STRONGER STORMS. LIKEWISE...A
DECREASE IN INTENSITY WITHIN THE ONGOING CONVECTION HAS BEEN NOTED
OVER THE PAST COUPLE OF HOURS.

WHILE SHEAR PROFILES REMAIN FAVORABLE FOR ROTATION WITHIN ANY
SUSTAINED/STRONGER UPDRAFT...A CONTINUED DECREASE IN CONVECTIVE
INTENSITY IS FORECAST GIVEN THE LACK OF INSTABILITY...AND GIVEN THE
STRONGER LARGE-SCALE FORCING CONTINUING ITS NEWD SHIFT AWAY FROM
THIS REGION. WHILE AN ISOLATED/BRIEF TORNADO REMAINS POSSIBLE OVER
THE NEXT COUPLE OF HOURS...THREAT SHOULD CONTINUE TO SLOWLY DIMINISH
THIS AFTERNOON.
