   Valid 190100Z - 191200Z

   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Although a lightning strike or two may be possible along the
   immediate Oregon coast, thunderstorms are not expected across the
   continental United States overnight.

   ...Oregon Coastal Areas...

   Cooling mid-level temperatures and increasing ascent as a shortwave
   trough approaches the Pacific Northwest may result in enough
   instability along the Oregon coast for a lightning strike or two
   early Sunday morning. Cool surface temperatures and weak buoyancy
   will limit the overall thunderstorm risk.

   ...Desert Southwest...

   A strong shortwave trough will continue to move across the southwest
   United States and northern Mexico overnight. However, the coldest
   mid-level air is now south of the United States-Mexico border with
   any destabilization occurring across Mexico. The lack of instability
   across the Desert Southwest should preclude thunderstorm development
   overnight.

   ...Southeast United States...

   Marginal instability and weakening low-level convergence should
   limit the thunderstorm potential overnight.
