Day 2 Convective Outlook 
NWS Storm Prediction Center Norman OK
1236 AM CDT Mon Sep 19 2022

Valid 201200Z - 211200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE WESTERN GREAT LAKES REGION...

...SUMMARY...
Thunderstorms associated with hail and strong wind gusts may occur
on Tuesday across parts of the western Great Lakes.

...Western Great Lakes...
Zonal flow will be in place on Tuesday across much of the
north-central U.S. A 65 to 80 knot mid-level jet associated with a
shortwave trough will move into western Ontario as a belt of
stronger low-level flow remains over parts of the Upper Midwest. To
the south of this mid-level jet, a cold front will advance
southeastward across the northern Plains and upper Mississippi
Valley. Ahead of the front, a moist airmass will be in place from
southern Wisconsin east-southeastward into southwestern lower
Michigan, where surface dewpoints are forecast from 65 to 70 F. As
surface temperatures warm during the day, moderate instability is
expected to develop along this corridor. A capping inversion across
much of the region will prevent convective initiation in most areas.
Storms that can initiate in spite of the cap will be elevated. For
this reason, any severe threat that develops should remain isolated
and marginal. Hail and a few strong wind gusts could occur with the
stronger cells.
