   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms appear unlikely across the contiguous United
   States on Wednesday.

   ...Synopsis and Discussion...
   Isolated to widely scattered thunderstorms will probably be ongoing
   at the start of the period across parts of the Southeast in a modest
   low-level warm advection regime. Due to a prior frontal intrusion
   into the northern Gulf of Mexico, the bulk of this morning
   convection is expected to remain elevated, with only weak MUCAPE
   forecast. As a large-scale upper trough progresses quickly eastward
   across the eastern CONUS through the day, these thunderstorms will
   likewise move off the Atlantic Coast. Latest guidance is in general
   agreement that modest low-level moisture will be in place across
   parts of north FL and southern GA ahead of a reinforcing cold front.
   Some potential for surface-based thunderstorms may exist across this
   region Wednesday afternoon. But, poor low-level convergence along
   the front as low/mid-level winds quickly veer to westerly and
   particularly poor mid-level lapse rates should tend to limit overall
   thunderstorm coverage and intensity.
