   Valid 150100Z - 151200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe storms are no longer expected through Monday morning.

   ...Southeast...
   As the lead wave continues to move northeast across the Mid
   Atlantic, lift will continue to decrease over FL. The 00Z soundings
   show a pronounced subsidence inversion in the midlevels. Therefore,
   while still moist and unstable over the peninsula, storms should
   remain concentrated over the Atlantic along the cold front.

   Elsewhere, elevated thunderstorms are expected to increase in
   coverage from southeast TX into the lower MS Valley tonight, as
   large-scale lift increases ahead of a powerful upper trough. Given
   the cold air already in place at the surface, severe storms are
   unlikely.
