   ...NO THUNDERSTORM AREAS FORECAST...

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

   ...Synopsis...
   A series of impulses will rotate around a broad upper-level trough
   across eastern portions of the U.S. on Tuesday.  At the surface, a
   dry/stable low-level air mass will remain in place across the CONUS,
   and thunderstorms are not expected to develop.  A very isolated
   lightning strike will be possible, however, over RI and eastern
   sections of MA/CT Tuesday afternoon as a zone of strong large-scale
   ascent lifts northeast across the region.
