The strong wind cores hit areas between Claremont and West Concord, MN in Dodge County, from Osage to Alta Vista, IA, and in the McGregor, IA area.  Numerous wind gusts of 70 mph or slightly higher were received.

Later in the evening, storms redeveloped further north in western Wisconsin. These repeatedly hit the same areas just east of the Mississippi River into the Wisconsin River valley.  Many towns were flooded out by 6-8" of rain and many rivers rose or will rise to major flood stage.
