Scattered clusters of thunderstorms, some severe, moved east-southeast through south-central and southeast Wisconsin during the late afternoon and early evening hours. They eventually merged into a line of storms as they moved into Racine and Kenosha Counties. Damaging straight-line winds, gusting to an estimated 50 to 56 knots (58 to 65 mph), toppled large trees and/or power lines and poles near Waldo (Sheboygan Co.), east of Spring Prairie (Walworth Co.), near Richmond (Walworth Co.), in the Burlington to Racine area (Racine Co.), around the city of Kenosha (Kenosha Co.), just northwest of Hartford (Washington Co.), from West Allis into Milwaukee (Milwaukee Co.), from the UW-Madison campus to the Capital Square in Madison (Dane Co.), in the city of Waukesha (Waukesha Co.), and in/near Orfordville (Rock Co.).  One person was injured at the State Fair Park in West Allis when the powerful thunderstorm winds blew a fence onto that person's head.  Two homes and several vehicles  in the city of Milwaukee sustained tree damage.  In Orfordville, two buildings were damaged by toppled trees.  Utility companies reported that nearly 40,000 customers lost electrical power as the storms passed through, 19,000 of them in Milwaukee County alone.  Very heavy rains of 1 to 2 inches accompanied the storms, resulting in urban flooding in the city of Milwaukee.  Manhole covers popped in the city and there were reports of 6 inches of water covering some of the city's streets.
