   Valid 230100Z - 231200Z

   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
   OF THE CENTRAL AND EASTERN GULF COAST REGION...

   ...SUMMARY...
   Isolated damaging gusts and a brief tornado or two remain possible
   tonight across parts of southern Alabama and the Florida Panhandle,
   and possibly into southwest Georgia.

   ...Discussion...
   A large area of pre-frontal convection continues across parts of the
   southeast U.S. this evening.  Prior rotating storms near the
   Alabama/Florida Panhandle coast have weakened, as the loss of
   diurnal heating and increasingly widespread convection have reduced
   the already modest available instability.

   With that said, ample shear -- including some turning in the lowest
   couple of KM with height -- will persist across the area into the
   overnight hours.  As such, will maintain a MRGL risk area for
   locally gusty winds or even a brief tornado or two, and will expand
   this risk area a bit eastward -- into southwest GA and the remainder
   of the FL panhandle -- per latest CAM runs suggesting an increase in
   warm-advection-driven storms over the next few hours across this
   area.
