The tornado warning was issued shortly before 9 p.m. on Wednesday, July 12.
The watch is in force until 3 a.m. Thursday in Wayne, Oakland, Macomb, Washtenaw, Monroe, Livingston, and Lenawee counties.
Tonight, multiple tornadoes were verified in the Chicago area, including downtown. Those storms are currently crossing Lake Michigan and travelling east at about 30 miles per hour.
The concern is whether the dynamics required to produce severe thunderstorms with the potential for isolated tornadoes will still be present by the time these clusters reach Southeast Lower Michigan.
At this moment, it appears that we will have sufficient ingredients for severe weather, including supercells, particularly in our southern region closest to the Ohio border.
Parts of Monroe, Lenawee, Washtenaw, and Livingston counties are currently under a category 2 minor danger of severe weather.
The primary hazard remains heavy rain and flooding. Strong wind gusts of more than 60 mph and isolated tornadoes are still probable.
Based on recent radar observations, the timing has been pushed back to roughly 10 p.m. to 3 a.m. The rest of Metro Detroit will continue to see heavy rain, with flash flooding possible after midnight but ending before the morning commute.
Kim Adams of Local 4 will be tracking these storms for you over the next few hours. More data will be added, including several updates and fresh facts.
