Day 1 Convective Outlook

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.
