   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not currently forecast across the contiguous
   United States on Monday.

   ...Synopsis...
   A long-wave mid-level trough will exit the East Coast into the
   western Atlantic as a ridge builds over the High Plains.  Surface
   high pressure centered over the lower MS Valley will lead to
   tranquil conditions for a large part of the area east of the
   Rockies.  Models show a weak mid-level trough over southern CA.  A
   few high-based showers and possibly a thunderstorm could develop
   over southern NV and perhaps the far southern Sierra Nevada. 
   However, the thunderstorm risk appears too negligible to warrant an
   areal thunderstorm highlight at this time.
