What happened
The episode as NWS MKX wrote it up.
The 3rd round (June 10th) of severe weather during the week was more widespread than the 2nd round. The usual large hail and/or damaging thunderstorm wind reports were common (large trees knocked over), as well as isolated flash flooding or urban/small stream flooding. In addition, 3 people were injured in Elkhorn (Walworth Co.) when lightning struck nearby. Torrential rains of 1 to 2 inches within 1 to 2 hours, on top of saturated soil, hit the Rock Springs to Leland area in Sauk County. A road near Leland was washed out by the flood waters. Excessive rainfall also generated urban-type flooding in the Columbus (Columbia Co.) area in which water was 4 to 6 inches deep on some roads. Just west of Beaver Dam (Dodge Co.), 2.5 inches of rain fell in only 45 minutes, resulting in urban-type flooding. Water levels on some roads ranged from 6 inches to 1 foot. Flash flooding hit the south side of the city of Milwaukee (Milwaukee Co.) after 2 to 3 inches of rain fell within 1.5 hours. Several cars were reported to be "floating" down the streets and some were flipped over. Urban/small stream flooding occurred north of Ladoga (Fond du Lac Co.) along and near Highway 26, after 1 to 2 inches fell in a 2 hour period. Powerful downburst winds blew 2 cars and a semi-tractor trailer off Interstate 43 near Elkhorn (Walworth Co.). Later on, powerful thunderstorm winds flipped yet another semi off Interstate 43 near Delavan (Walworth Co.). The driver was injured.
