   Valid 250100Z - 251200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Organized severe thunderstorms are not forecast through early
   Tuesday morning.

   ...Synopsis...
   Water-vapor imagery shows a mid-level trough over the Yellowstone
   National Park vicinity and this feature is forecast to move east to
   be near the Black Hills at sunrise.  Isolated thunderstorms will
   accompany this perturbation mainly over the north-central High
   Plains  as ascent overspreads the region.  Farther east, a weak
   mid-level disturbance over the OH Valley will move northeast into
   the Lake Ontario/NY area.  Numerous showers and widely scattered
   thunderstorms will gradually move north-northeast during the evening
   across the TN Valley and into the central Appalachians during the
   overnight.  The outflow-dominant character of the convection will
   preclude a severe risk.
