   Valid 090100Z - 091200Z

   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not expected through the remainder of the evening
   and overnight.

   ...Discussion...
   While brief lightning activity was noted across the Pacific
   Northwest earlier today, it has since diminished, concurrent with
   the passage of large-scale ascent to the east. Elsewhere, dry/stable
   conditions are yielding thermodynamic profiles hostile to deep
   convection.
