0740 AM CST MON NOV 26 2007
AREAS AFFECTED...FL PANHANDLE/SWRN GA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 261340Z - 261545Z
ISOLATED DMGG WIND GUSTS WILL BE POSSIBLE WITH INDIVIDUAL CONVECTIVE
CELLS WITHIN A SOLID LINE MOVING EWD ACROSS THE FLA PANHANDLE. THE
SMALL AREAL EXTENT AND MARGINAL NATURE OF THE SVR THREAT SHOULD
PRECLUDE THE NEED FOR A WW.
SFC MESOANALYSIS INDICATES A WARM FRONTAL BOUNDARY HAS LIFTED NWD
THROUGH PENSACOLA AND EXTENDS FROM SRN WASHINGTON COUNTY SEWD INTO
WRN FRANKLIN COUNTY. THE AIRMASS SOUTH OF THIS BOUNDARY WAS
MARGINALLY UNSTABLE AS DEWPTS HAVE RISEN TO AROUND 70 DEG F
SUPPORTING MUCAPE AROUND 1000 J/KG. A WELL ORGANIZED CONVECTIVE LINE
WILL CONTINUE TO MOVE EWD AROUND 20 KTS ACROSS THE FLA
PANHANDLE/SWRN GA OVER THE NEXT SEVERAL HOURS WITH INDIVIDUAL
CONVECTIVE CELLS MOVING NEWD AROUND 40 KTS. STRONG LOW LEVEL SHEAR
/0-1 KM SHEAR AROUND 30 KTS PER THE VWP AT TLH/ ALONG THIS BOUNDARY
MAY SUPPORT A BRIEF/WEAK TORNADO WITH ANY CELL THAT INTERACTS WITH
THE BOUNDARY. IN ADDITION...GIVEN THE SPEED OF INDIVIDUAL
CELLS...ISOLATED DMGG WING GUSTS WILL ALSO BE POSSIBLE. MORE STABLE
AIRMASS /DEWPTS IN THE MID 60S/ TO THE NORTH OF THE WARM FRONT OVER
SWRN GA SUGGESTS LIMITED SEVERE POTENTIAL IN THIS AREA.
