Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0551 AM CST Sun Nov 07 2021
Valid 071300Z - 081200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected across the contiguous U.S.
today.
...Pacific Northwest...
A steep lapse rate and onshore flow regime will persist through the
first half of today, supporting scattered low-topped showers through
this afternoon. Despite surface dew points only around 38-41 F,
scant buoyancy should be adequate for sporadic lightning flashes in
the stronger updrafts, mainly along the coast. Very small hail is
also possible owing to moderate speed shear and the cold thermal
profiles. Thunderstorm potential will diminish this evening and
especially into the overnight as mid-level temperatures warm well in
advance of the next upper trough approaching on D2.
