Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0654 PM CST Thu Nov 17 2022

Valid 180100Z - 181200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Sporadic lightning flashes are possible across parts of the lower
Great Lakes within lake-effect snowbands.

....DISCUSSION...
An upper-level trough will move southward across the western U.S.
tonight as a broad cyclonic flow pattern remains in place across the
eastern half of the nation. At the surface, high pressure will
remain across the Southeast, as another area of high pressure moves
southward into the northern Rockies and central to northern High
Plains. This cold and dry airmass will be unfavorable for
thunderstorm development across most of the U.S. The only exception
will be in the lower Great Lakes, where a few lightning strikes
could occur in association with lake-effect snowbands.
