Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0211 AM CDT Fri Nov 05 2021
Valid 071200Z - 081200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected on Sunday.
...Synopsis...
A broad, low-amplitude mid/upper trough will spread across the
Intermountain West to the northern Plains/Upper Midwest on Sunday. A
few lightning flashes are possible along the WA and northwest OR
coasts as a couple of shortwave impulses move inland. Meanwhile, an
upper ridge will shift east of the Mississippi River while the
eastern upper trough tracks offshore into the western Atlantic. A
surface cold front will develop east/southeast across the
northern/central Plains vicinity, but a lack of moisture and a
stable boundary-layer will preclude thunderstorm activity.
