   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Isolated thunderstorms will be possible across the Ozarks early
   Wednesday. A few thunderstorms will also be possible across
   southeast Florida.

   ...Discussion...
   As a compact shortwave trough advances east overnight across the
   southern Plains, it should continue to foster weak mid-level
   buoyancy and isolated thunderstorms. Some convective activity will
   likely persist past 12Z, such that a few thunderstorms will remain
   possible as the impulse approaches the Ozarks. However, as it
   continues to de-amplify through the day, weakening large-scale
   ascent will support a downward trend in thunderstorms. 

   Across southeast Florida, a combination of modest surface-based
   buoyancy and weak ascent associated with minor vorticity maxima over
   the region will likely encourage a few thunderstorms through the
   period.
