AREAS AFFECTED...SRN AL/CNTRL MS/NERN LA/SERN AR/SRN GA/NRN FL

CONCERNING...SEVERE THUNDERSTORM WATCH 639...641...

VALID 152218Z - 160015Z

MARITIME BOUNDARY MOVING THROUGH SWRN/SCNTRL GA SHOULD CONTINUE TO
UNDERCUT CONVECTION IN THESE AREAS...SO SEVERE THREAT SHOULD BE
DIMINISHING WITH TIME. EARLIER STORMS ACROSS NERN FL HAVE ALSO
SOMEWHAT STABILIZED AIRMASS IN THAT REGION GIVEN THE LACK OF NEW
CUMULUS NEAR JAX. SO...MAIN THREAT FOR WW 641 WILL BE IN THE WRN
PORTION OF WW FROM MAI/DHN WEST...AND IN NE PART OF WW. THERE IS A
WEDGE OF UNSTABLE AIR ACROSS SRN AL NOT CURRENTLY INCLUDED IN
PRESENT WATCHES  WHICH HAS NOT YET BEEN OVERTURNED. A SHORT TERM
SEVERE THREAT EXISTS HERE...WITH ACTIVE CONVECTION DEVELOPING ALONG
THE SYNOPTIC BOUNDARY PER LATEST VISIBLE IMAGERY. 

ACROSS WW 642...SEVERE THREAT PERSISTS ACROSS THE MAJORITY OF THE
WATCH...AS STORMS DEVELOP IN A VERY UNSTABLE AIRMASS.
