The storm complex from Monday afternoon into evening has been classified as a derecho by the Storm Prediction Center. The featured lapse combines NWS RADAR, Warnings, and Local Storm Reports between 3 PM and 1 AM Tuesday. The bottom panel attempts to illustrate the persistence of significant wind gust reports with each report having a five minute plot width. You can see that the line was producing consistent wind gusts reports for much of the evening hours. Additionally, EF1 rated tornadoes were confirmed within the Des Moines Metro and Davenport as well.
