   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not expected across the U.S. through early
   Tuesday.

   ...Synopsis...
   Northwesterly flow aloft will extend from the northern Rockies to
   the southeast Atlantic coast.  This pattern will maintain surface
   ridging across the Southeast and Gulf coast, which will limit any
   potential for inland moisture transport and any associated
   thunderstorm threat.
