   Areas affected...Gulf Coast

   Concerning...Severe Thunderstorm Watch 364...

   Valid 122328Z - 130100Z

   The severe weather threat for Severe Thunderstorm Watch 364
   continues.

   SUMMARY...A few damaging wind gusts will remain possible with the
   thunderstorm complex as it moves offshore and out of WW364.

   DISCUSSION...The cluster of thunderstorms across south Alabama,
   Mississippi, and the Florida Panhandle is approaching the Gulf
   Coast. A general weakening trend has been noted via decreasing radar
   echo top heights over the last hour. This trend should continue
   given the lack of strong forcing for ascent and the gradual decrease
   in buoyancy as the storms continue toward the instability gradient.
   Despite weakening, a few strong wind gusts will remain possible with
   the complex as it moves toward the Gulf Coast and off shore within
   the next hour or two. Redevelopment on the western edge of the
   complex across southern Mississippi will likely pose the greatest
   threat for strong wind gusts given more robust surface based
   buoyancy of 2000-3000 J/kg. Thus, the severe threat remains across
   WW364.
