Mesoscale Discussion 1571
NWS Storm Prediction Center Norman OK
0629 PM CDT Sat Jul 23 2022
Areas affected...southeast Wisconsin...western Lower Michigan
Concerning...Severe Thunderstorm Watch 493...
Valid 232329Z - 240130Z
The severe weather threat for Severe Thunderstorm Watch 493
continues.
SUMMARY...Damaging wind gusts remain possible with an MCS as it
moves from eastern Wisconsin across Lake Michigan. An additional
watch may be needed over western Lower Michigan.
DISCUSSION...Storms have developed into a more organized MCS over
the past hour with measured severe winds near 50 kt. The leading
edge of the outflow is now moving east at around 40 kt, with a more
laminar/contiguous radar presentation.
The air mass over Lower MI overall is less unstable than over WI,
with up to 1000 J/kg MLCAPE analyzed. Isolated cells over northern
MI have dwindled over the past hour, further suggesting increasing
inhibition. That said, the outflow surge with the MCS is strong, and
may persist into Lower MI. If storm trends remain favorable as
storms cross the lake, a new watch could be needed.
