Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1202 PM CDT Sun Oct 31 2021
Valid 011200Z - 021200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms will not occur over the contiguous United
States on Monday.
...Synopsis...
Cyclonic upper flow will be maintained from the northern Plains to
the Northeast as an upper low migrates across Quebec and Ontario.
Cold temperatures aloft and weak shortwave impulses migrating around
the upper low may be sufficient for a few thunderstorms across parts
of the Upper Peninsula of MI eastward toward Lake Huron. A few
lightning strikes also may occur near higher terrain of northern CO.
Otherwise, surface high pressure centered over the northern/central
Plains and a dearth of boundary-layer moisture will preclude
thunderstorm activity across most of the contiguous U.S. on Monday.
