The G.R. National Weather Service did issue one Tornado Warning Wednesday evening – for Western Allegan County. There’s a separate thread with some pics. on that from W. Allegan Co:

Storm Reports from Wed. 5 25 22

There was one small and very brief confirmed tornado northwest of Beloit, Wisconsin. There were 18 reports of wind damage in Indiana – as close as Dyer and Munster (my wife’s hometown), 7 reports of wind damage in Illinois, and 4 reports each in S. Wisconsin and W. Ohio.

About mid-afternoon, SPC upgraded the Marginal Risk to a Slight Risk Area (level 2) across N. Indiana and small parts of NE Illinois and extreme SW Michigan. There were tornado warnings west of Chicago in NE Illinois. The Marginal Risk Area comes up to Grand Rapids.

There were 37 of reports of wind damage in Mississippi – most were lined up near the Natchez Trace Parkway. At one point downed trees blocked both southbound lanes of I-55 near Wesson and chicken houses were extensively damaged near the town of Geraldine.



Today (Thurs.) there will be a Low or Marginal Risk of a severe thunderstorm south of a line from Holland to Grand Rapids to Flint. Very isolated wind damage would be the risk.

We’ll be tracking any storms that do develop this PM.
