Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
1153 AM CDT Sat Jul 23 2022

Valid 231630Z - 241200Z

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS THE
UPPER MIDWEST AND GREAT LAKES...

...SUMMARY...
Damaging thunderstorm gusts (some over 75 mph), a few tornadoes and
large to very large hail will be possible today across parts of the
Upper Midwest and southern Great Lakes regions.

...Upper Midwest and southern Great Lakes...
Current MCS across southern Minnesota with a recent history of
measured strong/severe wind gusts should continue to organize/grow
upscale as it thrives along the instability gradient toward southern
Wisconsin and far northeast Iowa and possibly far northern Illinois
through the afternoon. Damaging winds will likely be the most co*mon
hazard, but isolated large hail may also occur along with at least
some tornado risk. Additional severe storms are also likely to
develop along the southeastward-moving front this afternoon/early
evening across southern Minnesota/northern Iowa southwestward into
the central Plains, including parts of Nebraska and northern Kansas,
where severe-caliber wind gusts will be most probable risk.

...Midwest/Ohio Valley...
A quasi-linear MCS persists at midday across Ohio with at least some
persistent potential for wind gusts, with a bit of rejuvenation
possible as the downstream air mass diurnally destabilizes.
Additional isolated/episodic severe storms will remain possible
across northern Illinois/northern Indiana into Ohio along the
trailing boundary and atop the remnant surface cold pool. A
secondary round of storms via the Minnesota/Wisconsin MCS could move
into parts of the region later tonight, most probable in areas
farther to the north toward the Lake Michigan vicinity.
