0744 AM CST FRI APR 01 2005

AREAS AFFECTED...CENTRAL AND ERN FL PANHANDLE AND NRN FL INTO SRN GA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 011344Z - 011545Z

SEVERE THREAT IS EXPECTED TO INCREASE ACROSS PARTS OF NRN FL / THE
FL PANHANDLE INTO SRN GA.  WE WILL CONTINUE TO MONITOR AIRMASS
DESTABILIZATION ACROSS THIS REGION...AND ASSOCIATED POTENTIAL FOR
NEW WW IN THE NEXT 1 TO 2 HOURS.

LATEST RADAR REFLECTIVITY LOOP SHOWS MESOLOW DEVELOPING OVER S
CENTRAL AL ATTM.  STORMS WHICH WERE EARLIER OVER SRN LA / SRN MS /
SRN AL HAVE EVOLVED INTO A BOW-SHAPED ECHO S OF THIS MESOLOW /
ACROSS WRN PORTIONS OF THE FL PANHANDLE.

THOUGH BOUNDARY-LAYER AIRMASS REMAINS STABLE ATTM AS OUTFLOW
BOUNDARY REMAINS OFF THE FL PANHANDLE COAST IN THE NERN GULF...THIS
BOUNDARY SHOULD RETURN NWD AS A WARM FRONT AS SURFACE WIND INCREASES
FROM THE S AHEAD OF MESOLOW.  AS BOUNDARY LAYER RETREATS AND LIMITED
HEATING COMMENCES THROUGH BREAKS IN OVERCAST...DESTABILIZING
BOUNDARY LAYER SHOULD ALLOW BOWING LINE OF STORMS TO BECOME
INCREASINGLY SURFACE-BASED.  THUS...GIVEN FAVORABLY-STRONG
DEEP-LAYER WIND FIELD OBSERVED ACROSS THIS REGION...EXPECT THREAT
FOR DAMAGING WINDS TO INCREASE OVER THE NEXT COUPLE OF HOURS --
POSSIBLY REQUIRING WW ISSUANCE.
