Morning showers and storms tracked east, northeast across parts of southeast Minnesota and northeast Iowa into western Wisconsin on the morning of June 15th. Mostly non-severe at this time, although there were a few that did produce some hail and stronger wind gusts.

By early afternoon, another round of storms fired off over southeast Minnesota and northeast Iowa. These storms were slow to strengthen, but as they moved into southwest Wisconsin, they began to increase in strength. What was initially a hail and wind threat turned to tornadoes in west central Wisconsin. In addition, straight-line winds in this same location produced a swath of wind damage. 

Most of the storms exited into eastern and southern Wisconsin after 6 pm where they continued to produce severe weather. (NWS Green Bay) (NWS Milwaukee/Sullivan)
