AREAS AFFECTED...THE FL PANHANDLE THROUGH SWRN GA
CONCERNING...TORNADO WATCH 54...
VALID 130425Z - 130600Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 54 CONTINUES.
SOME THREAT FOR ISOLATED DAMAGING WIND GUSTS AND POSSIBLY AN
ISOLATED TORNADO PERSISTS OVER THE FL PANHANDLE INTO SWRN GA.
HOWEVER...THE OVERALL THREAT APPEARS SOMEWHAT MARGINAL.
LATE THIS EVENING A PRE-FRONTAL SQUALL LINE EXTENDS FROM CNTRL GA
SWWD THROUGH SWRN AL INTO THE FL PANHANDLE WEST OF TALLAHASSEE. THE
LINE IS MOVING EAST AT 25 TO 30 KT. OVERALL TRENDS DURING PAST HOUR
HAVE BEEN FOR THE STORMS TO UNDERGO AN OVERALL WEAKENING TREND DUE
MOST LIKELY TO THE INCREASINGLY MARGINAL THERMODYNAMIC ENVIRONMENT
WITH EWD EXTENT INTO SWRN GA. OBJECTIVE ANALYSIS SHOW MUCAPE AOB 300
J/KG AND TRENDS IN LIGHTNING INDICATE A CONSIDERABLE DECREASE WITH
VERY LITTLE LIGHTNING CURRENTLY OBSERVED. BULK SHEAR IS SUFFICIENT
FOR EMBEDDED LEWPS AND SUPERCELLS...BUT LOW LEVEL HODOGRAPHS WILL
REMAIN MODEST AS THE PRIMARY LOW LEVEL JET SHIFTS NEWD TOWARD THE
CAROLINAS OVERNIGHT.
