   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Isolated thunderstorms possible for a short time this evening over
   the coastal Mid-Atlantic, with sporadic lightning flashes over the
   northern Rockies. Severe weather is not expected.

   ...Synopsis...
   Scattered showers and thunderstorms currently exist along the cold
   from over the Mid Atlantic, and remain weak due to limited
   instability. This front will continue to push rapidly offshore along
   with the parent trough. Elsewhere, isolated lightning flashes remain
   possible this evening over the northern Rockies beneath an upper
   wave within the northwest flow regime. However, this activity is
   expected to wane as well with the loss of heating.
