In southeast Michigan, where the risk for severe storms is higher, the timeframe for this is noon to 5 p.m., the NWS in Detroit said. The hazards possible during this time include not only high winds, but large hail, too. Wind gusts could top 60 mph during this time.

The threat of strong tornadoes, damaging hail and high winds is highest in the upper Midwest through Monday night. Severe weather and heavy rain will then stretch from the Great Lakes to the Southern Plains on Tuesday.

"A regional severe weather outbreak still appears possible across the Upper Midwest, with a threat of strong to intense tornadoes, very large hail, and swaths of damaging winds," said NOAA's Storm Prediction Center (SPC) in an update issued at 7:37 a.m. Monday.
