A thunderstorm complex  formed in northeast Colorado just after midnight Tuesday. This complex traveled across three states to arrive in the local area in the afternoon.

The line of thunderstorms produced winds in the 30 to 50 mph range to much of northeast Iowa and parts of southeast Minnesota. More importantly, it provided a much needed break from the heat, dropping the temperature nearly 20 degrees. The complex turned south into Iowa and never made it into Wisconsin...but the rain cooled air did. 

There were pockets of wind damage in the area. See the reports at the bottom of the story.
