Large Hail, Isolated Tornadoes Possible in Lower Michigan Friday

updated at 11:45am on 4/17/25

There's increasing confidence among weather forecasters that much of Lower Michigan - including Lansing, Grand Rapids, Detroit, Flint and Kalamazoo - could be at risk for severe weather this Friday.

The potential for large hail and isolated tornadoes appear to be the main threats at this time, according to the National Weather Service's Storm Prediction Center.

Much of Friday will be pleasant with highs well into the 70s across Lower Michigan. The storms are expected to fire off by late afternoon into the early evening.

Will There Be Tornadoes in Michigan This Friday?

The National Weather Service currently has the southern half of Lower Michigan at a "slight" risk of severe storms on Friday. NWS forecasters say "a few non-severe storms are expected early Friday morning. Additional storms will develop Friday evening. The evening storms could become severe with damaging winds the main threat."

Chief Meteorologist Darrin Rockcole with WILX News 10 in Lansing says Friday's weather - especially late in the day - will definitely be worth keeping an eye on.

"Late Friday night a slow moving cold front moves into the area," Rockcole says. "The front may be the trigger for stronger thunderstorms to rapidly develop and race across Mid-Michigan."
