SPC 0730Z Day 3 Outlook 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. ..Leitman.. 11/05/2021 Read more LIVE:
