Severe thunderstorms moved northeast from a point 8 miles west of Rock Island, Wisconsin, to a point near Detroit Island, Michigan, and then to a point 7 miles east of Jacksonville, Florida. Hail of up to a quarter of an inch in diameter and wind gusts of over 50 knots are possible.

Northwest Lower Michigan

8:18 p.m. There has been a mesoscale update issued by the Storm Prediction Center discussing potential thunderstorm behavior in northwest Lower Michigan. This is the latest development:

The affected areas span from the northernmost parts of lower Michigan to the upper peninsula. The risk of severe weather associated with Tornado Watches 371 and 372 has not decreased since the previous statements.

By 9-11 PM EDT, the organized cluster of storms may maintain considerable strength across at least portions of northern Lake Michigan into northern lower Michigan, raising the prospect of damaging wind gusts. A new severe weather watch may not be required, but forecasts are being closely watched just in case.

Rear inflow strengthening pockets and near the surface characterize the well-organized mesoscale convective system discussed here. However, the effects of a less unstable, more inhibited boundary layer near and east of Lake Michigan remain unknown as rapid forward (northeastward and eastward) propagation persists.

Rapid Refresh says that a drier lower and middle tropospheric air mass is moving northward through the southern parts of Lake Michigan.

However, a more moist environment farther north, along with lift-associated warm advection, may keep storms strong and slightly elevated across northern Lake Michigan and into northern lower Michigan by 9 to 11 p.m. It’s possible that damaging winds could blow in from time to time in certain areas.

Thunderstorm

7:54 p.m. Menominee County in South Central U.P. is under a Severe Thunderstorm Warning from the National Weather Service in Marquette. In the US, it begins at 8:30 pm EST (7:30 pm CDT). A severe thunderstorm was also located 26 miles southeast of Iron Mountain and was moving 45 mph northeast.
