NWS Storm Prediction Center Norman OK
1253 PM CDT Mon Aug 29 2022

Areas affected...northern Illinois and Indiana...southwest Lower
Michigan

Concerning...Severe Thunderstorm Watch 527...

Valid 291753Z - 292000Z

The severe weather threat for Severe Thunderstorm Watch 527
continues.

SUMMARY...Strong to severe wind gusts remain possible across watch
527, and an additional watch may be needed downstream into parts of
Lower Michigan and northern Indiana.

DISCUSSION...A co*plex of storms with northern and southern outflow
bulges has gradually strengthened this afternoon, with gusts
generally 40-50 kt across northern IL. The northern section of this
line is now crossing into Lake MI, and will eventually emerge into
southwest Lower MI where strong instability is in place. The
southern half of the co*plex also remains strong, and may beco*e
dominant as it moves down the 3000+ MLCAPE instability axis into IN
later this afternoon. As such, an additional watch could be needed
prior to 19Z.
