   Areas affected...the Florida Panhandle into southwest Georgia

   Concerning...Severe potential...Watch unlikely 

   Valid 110742Z - 111115Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A gradual increase in thunderstorms is expected from parts
   of the Florida Panhandle into southwest Georgia, and isolated severe
   cannot be ruled out.

   DISCUSSION...Surface analysis shows a cold front extending from
   northern GA across southeast AL and into the northeast Gulf of
   Mexico. Meanwhile, a north-south oriented warm front remains draped
   across central GA into northern FL. MLCAPE over 500 J/kg exists
   across the warm sector currently, where upper 60s F dewpoints are
   prevalent. Also of note, are surface gusts in the 15-20 kt range,
   indicated a degree of boundary-layer mixing.

   Area VWPs show southwest winds around 40 kt about 1 km off the
   surface, which results in 0-1 km SRH over 100 m2/s2 near the coast
   to over 200 m2/s2 near the GA warm front.

   As such, any increase in convection tonight along or just ahead of
   the cold front could result in a brief tornado or damaging-wind
   risk, but coverage of severe is not expected to necessitate a watch.
