Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0628 PM CST Wed Dec 06 2023
Valid 070100Z - 071200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
Isolated lightning flashes remain possible across portions of the
northern Pacific Coastal region tonight.
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.
