Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0623 PM CST Sun Nov 07 2021
Valid 080100Z - 081200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
One or two flashes of lightning may be noted across northwest
Washington through 03z.
...Northwest WA...
Mid-level short-wave trough is ejecting inland along the
BC/northwest WA coast early this evening. Scattered convection has
been noted ahead of this feature with isolated lightning flashes
noted at times in the stronger updrafts, now mostly confined to
coastal Vancouver Island. 00z sounding from UIL continues to exhibit
steep lapse rates through 6km with 200 J/kg SBCAPE. While this
profile may continue to support an isolated thunderstorm for the
next few hours, passage of progressive short wave and diurnal
cooling should result in a negligible threat after 03z.
