Rain totals of just under six inches had been recorded by the NWS in Milwaukee early Sunday morning. The highest rain total was registered just west of the Menomonee River Parkway, in Butler, where 10 inches of rain was recorded.

Storms and flooding forced the Wisconsin State Fair to end early, leading to the cancellation of the main stage act by Southern rock band Lynyrd Skynyrd. Several parts of the Milwaukee area reported stranded vehicles and flooding in streets and basements to the NWS.

Benjamin Sheppard, a meteorologist with the NWS's Milwaukee office, told the Milwaukee Journal Sentinel that people in Milwaukee “can expect several rounds of thunderstorms, rain and wind through Monday morning.” He added that the storms may remain “unpredictable” in terms of how much and when they may intensify.
