What happened

The episode as NWS MKX wrote it up.

Several rounds of thunderstorms moved rapidly northeast through south central and southeast Wisconsin resulting in primarily wind damage to trees, tree limbs and power lines. In addition, a tree fell on a home in Sun Prairie (Dane Co.) and windows were blown out of a building on the UW campus in Madison. A porch was blown down at a residence northeast of Lamont (Lafayette Co.). Urban street flooding occurred in New Glarus due to 4.5 to 5.0 inches of rain in 3 hours. No damage was noted due to this flooding. Flag poles were bent and flags blown off in La Valle (Sauk Co.) besides the usual reports of large branches downed. In the Spring Green area a couple farm outbuildings and a residence were damaged. Strong thunderstorm winds split a large tree in in Chenequa (Waukesha Co.) which then fell on a residents porch and injured a woman. Intense rainfall also resulted in urban street flooding in North Freedom (Sauk Co.).
