000 ACUS02 KWNS 060657 SWODY2 SPC AC 060656 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1256 AM CST Sat Mar 06 2021 Valid 071200Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm development may occur along the Pacific Northwest Coast on Sunday, but no severe thunderstorms are expected across the continental United States Sunday and Sunday night. ...DISCUSSION... An upper-level ridge will move eastward into the Great Plains on Sunday, as an upper-level low moves southward across the northeastern Pacific. Southwest mid-level flow, associated with the Pacific low pressure system, will be in place across much of the western U.S. Strong large-scale ascent will overspread the Pacific Northwest as a lapse rates steepen across western Washington and western Oregon. These two conditions will make isolated thunderstorm development possible near the coasts of the Pacific Northwest today and tonight. Instability will be too weak for a severe threat. Elsewhere across the continental United States, thunderstorm development is not expected Sunday or Sunday night. ..Broyles.. 03/06/2021 $$
