Michigan Supercells Charge In with 1.75-Inch Hail, 70 MPH Wind Threats — SevereWX

Storms are ramping up across eastern Upper Peninsula and northern Lower Michigan this evening, fueled by a strengthening low-level jet and increasing moisture from the west. The Storm Prediction Center highlights a high risk of severe weather, with supercells and bowing segments likely to produce the main dangers: large hail up to 1.75 inches and wind gusts to 70 mph.

An upper-level jet streak is driving ascent over the region, allowing ongoing storms near Lake Michigan to organize into supercells as they push southeast. While a shallow near-surface inversion might keep storms slightly elevated—reducing the tornado odds—strong deep-layer shear will maintain structured storm modes capable of potent hail and wind threats. Peak forecasts include hail of 1-1.75 inches, winds of 55-70 mph, and any tornadoes at EF1-EF2 strength (85-110 mph).

A severe thunderstorm watch appears probable within the next couple hours, covering this timeframe through early Tuesday morning. Residents from Gaylord northward into the eastern U.P. should prepare for impacts, especially as storms intensify after sunset.

Stay prepared: Monitor local NWS updates, have a severe weather plan ready, and seek shelter if warnings are issued for your area.
