What happened
The episode as NWS MKX wrote it up.
A series of thunderstorms, slowly moving northeast at 10 mph, trained through the Delavan area, dumping 2 to 4 inches of rain. The resultant urban flooding generated water depths of 1 to 2.5 feet on some city streets. Some roads were closed, and several vehicles stalled. Just north of Delavan, Turtle Creek, which runs into Lake Comus, was reported to be 2 feet over flood stage. The synoptic reasons for this flooding can be found in the August 4th entry for flash flooding in Columbia Co.
