The episode as NWS MKX wrote it up.
Strong, post-cold-frontal, northwest winds gusting to 39 to 47 knots (45 to 54 mph) raked south-central and southeast Wisconsin during the daylight hours. They were accompanied by scattered rain/ice pellet/snow showers that briefly lowered visibilities to 1/2 to 1 mile. The media noted that wind-broken limbs fell on power-lines. Scattered power outages were the result. Additionally, about a dozen vehicles were damaged by the broken limbs. The strongest gusts were 47 knots (54 mph) at St. Roberts School in Milwaukee County (WITI TV-6 school network site), and 45 knots (52 mph) at Milwaukee Mitchell Field. Many of the strongest gusts occurred betwen 1100CST and 1400CST. Synoptically, a strong low pressure moved east across Lake Superior to Lake Huron while the trailing cold front swept southeast through Wisconsin.
