What happened
The episode as NWS MKX wrote it up.
Severe thunderstorms developed along an east-west orientated outflow boundary associated with earlier convection which moved east along the Illinois/Wisconsin border. The genesis region, initially over southwest Jefferson County, eventually shifted to west-central Walworth County. New cells displayed a back-building tendency toward the western Walworth County line. Slow movement of the storms led to torrential downpours of 1 to 2 inches in a 1 hour period. There were reports of standing water in low spots on farms in the western part of Walworth County. Otherwise, large hail stones were the only severe weather event.
The radar
The Milwaukee radar (KMKX), 22 km away, was scanning. The volume nearest the first event began at 19:40 UTC.
Event by event
