   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

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

   ...Synopsis and Discussion...
   Isolated weak/elevated thunderstorms may be ongoing at the start of
   the period Wednesday morning across parts of the Southeast in a
   modest low-level warm advection regime. As a large-scale upper
   trough moves quickly eastward across much of the eastern CONUS, this
   convection is forecast to likewise develop eastward towards the
   Atlantic Coast. Elevated instability ahead of this activity should
   remain quite meager due to a prior frontal intrusion into the
   northern Gulf of Mexico. There also appears to be some chance that
   modest low-level moisture may be able to advance inland across parts
   of north FL and southern GA by Wednesday afternoon. Regardless,
   mid-level lapse rates are forecast to be particularly poor, which
   should limit the degree of MLCAPE that can develop. While a few
   surface-based storms could form across this area during the day, the
   weak forecast instability suggests that the overall severe potential
   should remain low.
