SPC Nov 6, 2021 1630 UTC Day 1 Convective Outlook

SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1108 AM CDT Sat Nov 06 2021 Valid 061630Z - 071200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast across the contiguous United States today. ...Synopsis and Discussion... Multiple low-amplitude shortwave troughs will progress from the northeast Pacific across the Pacific Northwest and northern Rockies through tonight. Continued onshore flow along with steep low/mid-level lapse rates should support low-topped convection mainly this afternoon and evening. Isolated lightning flashes may occur with the strongest cores that can reach a depth sufficient for charge separation, primarily along and near the WA/OR Coast. Farther east, a shortwave trough over parts of the Southeast will move slowly east-northeastward over the Gulf Stream through the period. A related surface cyclone off the northeast FL Coast will develop east-northeastward in tandem with the shortwave trough. Mainly stratiform rain should prevail over land along the South Atlantic Coast as a marine front remains offshore. Still, the strong ascent associated with the shortwave trough coupled with meager elevated instability may support a storm or two in the nearshore waters off the southern NC Coast this afternoon through tonight. ..Gleason.. 11/06/2021 Read more LIVE:
