   Valid 210100Z - 211200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   The risk for severe thunderstorms appears negligible across the U.S.
   through tonight.

   ...Synopsis...
   Isolated thunderstorms will remain possible through tonight as a
   series of embedded shortwave troughs rotate inland over southwest
   OR, central CA and southern CA.  Forcing for ascent and cool
   midlevel temperatures/weak buoyancy will support the threat for
   additional lightning flashes the next few hours from southwest OR
   into central CA, as well as over parts of the Great Basin.  The
   potential for isolated thunderstorms will increase late
   tonight/early Wednesday across southern CA as the basal shortwave
   trough approaches the coast 06-12z.
