Detroit, Michigan – A narrow but impactful window for severe storms could disrupt travel and evening plans across southeast Michigan Thursday, with isolated tornadoes possible between 4 p.m. and 8 p.m.
According to the National Weather Service in Detroit/Pontiac, the southern half of the region is under a Level 1 to Level 2 severe storm risk, with storms potentially beginning as early as 3 p.m. and peaking during the late afternoon and early evening hours. Wind gusts could reach 60 to 70 mph, with hail up to one inch and a low-end tornado threat.
The highest risk stretches from Ann Arbor and Jackson through Detroit and Monroe, where conditions favor stronger storm development. Storms are expected to move northwest to southeast at around 40 mph, increasing the likelihood of quick-hitting impacts with little lead time.
Heavy downpours may reduce visibility below one mile and create ponding on major routes including I-94, I-75, and I-96. Localized flooding is possible in low-lying and urban areas during peak rainfall.
Residents should secure loose outdoor items, charge mobile devices, and be ready to move to a lowest-level interior room if warnings are issued. Outdoor activities should wrap up before mid-afternoon.
Storms are expected to exit by 9 p.m., but additional updates or advisories may follow as cooler air settles in overnight.
