Lake Michigan Storms Eye 55-70 MPH Gusts in Southern MI, Northern IN — SevereWX

A cluster of strong thunderstorms pulsing over northeast Illinois and southeast Wisconsin is set to track across Lake Michigan into southern Lower Michigan and northern Indiana this afternoon.

The Storm Prediction Center highlights ample instability fueling these storms, supporting local wind damage even amid some uncertainty in organization due to displaced upper-level flow. Peak wind gusts could reach 55-70 mph, with hail up to 1.25 inches possible. A severe thunderstorm watch appears likely soon, with an 80% issuance probability.

This activity ties into broader Great Lakes convection, but the focus here is the leading edge impacting areas from near Grand Rapids southward across Michigan into northern Indiana spots like South Bend and Fort Wayne vicinities. Populations in these regions should prepare for sudden severe downbursts.

Key Threats:

Stay tuned to local NWS updates from Detroit (DTX), Northern Indiana (IWX), and Grand Rapids (GRR) offices. Radar trends will clarify if storms intensify further.

Preparedness: Monitor radar closely, secure outdoor items, and have a severe weather plan ready—know your safe spot indoors away from windows.
