Overnight, temperatures will drop sharply, with highs around 40 degrees on Friday.
Weather threats
A Level 1 (marginal) risk for severe weather is in effect Thursday north of I-696 and toward I-69.
From I-696 southward into Ohio, there is a Level 2 (slight) risk of severe weather on Thursday.
All threats are on the table, but hail and tornadoes will be the most significant. Here’s what to expect:
- Hail: Conditions will be favorable for large hail (up to 2 inch/tennis ball-sized) even in the marginal risk area.
- Wind: Damaging wind potential will be little greater closer to the Ohio state line. However, most of the area will be at risk for isolated damaging wind gusts greater than 60 mph.
- Tornadoes: Tornado probabilities are a little higher in our southern communities, but isolated strong (EF-2+) tornadoes are not out of the question across much of Southeast Michigan.
- Flooding: Heavy downpours are possible, but flash flood risk remains low.
