There’s a shower with moderate rain northeast of Fremont. The storms that rolled through West Michigan around and shortly after noon are east into Ontario and Ohio this evening. A radio tower was blown down in Wauseon, Ohio this afternoon. An impressive shelf/roll cloud moved thru with these storms. Gusts to 65.6 mph (though suspect – now showing gust to 132.4 mph and we know that’s wrong) at the Muskegon Beach and 62 mph in Jamestown as the storms came in. Gust to 53 mph in East G.R. (high school press box). 30-40 mph gusts and heavy rain in Grand Haven. Tree down across half of Ada Dr. Near Ada Christian. Utility line and tree down in Mendon. Two trees fell on cars in Cass Co. at the town of Jones. Multiple trees were down in Edwardsburg (also Cass Co.). Springfield in Calhoun Co. reported a few limbs and wires down.

Small hail in DeWitt. Pics. of the storm coming into G.R. and Jenison. Here’s the Meso-discussion that was issued for S. Lower Michigan by the Storm Prediction Center for the storms that will move thru during the early afternoon. SPC says: “A WELL-DEFINED BOW ECHO MOVING ACROSS SRN PORTIONS OF LAKE MI ATTM…AND WILL BEGIN TO SHIFT INTO SRN LOWER MI IN THE NEXT HOUR OR SO. THE AIRMASS DOWNSTREAM OF THIS MCS HAS BEEN SOMEWHAT STABILIZED BY EARLIER CONVECTION…WITH BETTER INSTABILITY CONFINED TO AREAS NEAR AND S OF THE SRN BORDER OF LOWER MI. STILL…THE DEGREE OF ORGANIZATION OF THIS BOW AS INDICATED BY RADAR SUGGESTS THAT LOCALLY DAMAGING WINDS ALONG WITH MARGINAL HAIL MAY STILL BE POSSIBLE AS THE BOW MOVES EWD ACROSS THE REGION AT 40 KT.” Here’s W. Michigan radar and Regional radar. Nice 3-hour loop of the storms here. This line of storms did produce wind damage, 3/4″ hail and over 2″ of rain in S. Wisconsin. Beware of some local flooding in areas (S. Muskegon and N. Ottawa Co.) that got the most rain last night. Radar view of the storms over central Lake Michigan late morning.
