780 ACUS01 KWNS 310600 SWODY1 SPC AC 310558 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1258 AM CDT Sun Aug 31 2025 Valid 311200Z - 011200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few strong thunderstorms will be possible today across parts of the southern and central Plains, and the the Pacific Northwest. The severe potential appears to be low. ...DISCUSSION... Mid-level northwesterly flow will be in place today in the central U.S., as a moist airmass remains over much of the Great Plains. As surface temperature warm, isolated to scattered thunderstorms will develop over parts of the southern and central Plains this afternoon. Although a few strong storms could occur, the combination of instability and deep-layer shear will likely be too weak for an appreciable severe weather threat. In the Pacific Northwest, a mid-level low pressure system will affect western Washington, where isolated thunderstorms could develop during the day. In the Pacific Northwest, instability and deep-layer shear is also expected to be insufficient for a severe threat. Elsewhere across the continental United States, no severe threat is forecast today or tonight. ..Broyles/Thornton.. 08/31/2025 $$
