What happened
The episode as NWS MKX wrote it up.
The second round (June 8th) of severe weather across southcentral and southeast Wisconsin during the week wasn't as widespread as that on June 6th. Nonetheless, there were scattered clusters of severe storms that dumped large hail and/or generated strong downburst winds that toppled large trees and powerlines. Large hail damaged 20 vehilces and stripped several trees clean from Lowell to Juneau (Dodge Co.). In addition, torrential rains resulted in isolated flash flooding or urban/small stream flooding. Flash flooding (soil erosion and gravel shoulder washouts) occurred in Baraboo (Sauk Co.) after 3/4 inch of rain fell in 20 minutes on top of a saturated ground. Water levels on some streets reach 1 to 3 feet in depth.
The radar
The La Crosse radar (KARX), 109 km away, was scanning. The volume nearest the first event began at 22:43 UTC.
Event by event

- Thunderstorm Wind
- Winds from a thunderstorm of 50 knots (58 mph) or more, or lower winds that caused damage or casualties. Measured gusts are marked MG, estimated EG.
