   Valid 070100Z - 071200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Isolated lightning flashes remain possible across portions of the
   northern Pacific Coastal region tonight.

   ...01z Update...

   Early-evening water-vapor imagery depicts a lead short-wave trough
   ejecting inland across northern CA, arcing northwest off the OR/WA
   Coasts. Isolated flashes of lightning have been noted immediately
   ahead of the short wave, and primarily offshore, west of OR.
   Profiles will cool/steepen overnight as 500mb temperatures lower to
   -30C across western OR/WA, with values at least -20C north of the
   jet over northern CA. As a result, weak buoyancy will continue to
   favor some risk for isolated thunderstorms.
