   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not forecast across the Lower 48 states on Monday.

   ...Synopsis...
   A series of two rapidly-translating and southeastward-moving
   shortwave troughs over the Midwest and Great Lakes will act to
   reinforce a larger-scale longwave trough over the eastern states on
   Monday.  Dry/stable conditions will prevail over almost all of the
   contiguous U.S.
