Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0624 PM CST Tue Nov 09 2021
Valid 100100Z - 101200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast the remainder of tonight.
...Western US...
Quick-moving short-wave trough has progressed into central WA/OR
early this evening. While 00z sounding from UIL maintained weak
buoyancy at 10/00z, large-scale pattern is becoming less favorable
for lightning within weakening showers. Nocturnal cooling will also
prove negative, thus severe probabilities have been removed across
the Pacific Northwest.
A few lightning flashes may also spread across the Great Basin this
evening in conjunction with the short-wave trough ejecting across
this region.
