   Valid 291200Z - 301200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms are not expected on Wednesday.

   ...Synopsis...

   An upper ridge will overspread the Plains on Wednesday ahead of a
   closed upper low/trough moving southeast across CA into the western
   Great Basin. At the surface, high pressure will dominate across the
   Midwest and southern U.S., where a dearth of boundary-layer moisture
   will result in mostly stable conditions. A surface cold front will
   move across southern FL during the day, and a few thunderstorms are
   possible. Additional thunderstorms are expected across parts of CA
   where steepening midlevel lapse rates will support sufficient
   instability for isolated lightning flashes. Increasing southerly
   low-level flow across the southern Plains late in the period will
   begin to transport Gulf moisture northward across southern/central
   TX. Isolated, elevated thunderstorms will be possible after 00z in
   this warm advection regime. Overall severe potential is expected to
   remain low across the U.S. on Wednesday.
