   Valid 241200Z - 251200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are possible over the Florida Peninsula early in the
   day on Friday.  Severe thunderstorms are not forecast.

   ...Synopsis...
   A potent shortwave trough will quickly move east across the
   Midwest/Great Lakes while a mid-level ridge amplifies over the
   western states ahead of an east Pacific mid-level trough. 
   Thunderstorm activity will be associated with a weakening mid- to
   upper-level trough moving across FL and into the western Atlantic. 
   Early day shower and thunderstorm activity is possible across the FL
   Peninsula as weak large-scale ascent overspreads the region.  Weak
   instability will likely preclude intense thunderstorm development.  

   Elsewhere, tranquil conditions are forecast for a large part of the
   CONUS.
