   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms are not expected through tonight.

   ...Synopsis...
   A mid-level shortwave trough over the western Great Lakes will
   continue to quickly move east through the afternoon and a lingering
   thunderstorm cluster over west-central IL late this morning will
   gradually diminish as this disturbance becomes displaced.  

   Farther south, isolated to widely scattered thunderstorms will be
   possible from parts of the Mid-Atlantic southwestward to the Gulf
   Coast/Southeast.  Weak flow will limit storm intensity in these
   regions.  A vigorous shortwave trough will move across the Pacific
   Northwest and northern Rockies/Plains through tonight.  While
   large-scale forcing and mid-level flow associated with the upper
   trough passage will be strong, thunderstorm coverage is expected to
   remain sparse due to a rather dry airmass present across these
   areas.
