Scattered showers and thunderstorms developed continuously throughout the day as a surface trough pushed into south-central and southeast Wisconsin.  Several of these storms pulsed to severe levels and produced damaging winds and large hail.  Trees and power lines were toppled by the powerful winds.  In addtion, several funnel clouds were reported across Columbia, Jefferson, Dodge, Washington, and Fond du Lac county, and one weak tornado spun up 2.6 miles southwest of Wyocena and dissipated at 5.5 miles northeast of Poynette.  Refer to the individual tornado report for more details.  Numerous reports of trees damage were noted as a result from damaging winds from Sauk County, to Dane, Columbia, and Marquette counties.  More damage resulted when hail pelted cars across parts of Sauk, Dane, Green, and Waukesha counties.  Two to three inches of rain fell within a two hour timespan (WSR-88D estimate) resulting in urban flooding in the Middleton to Madison area.  Brief water depths of 1 to 3 feet slowed traffic or stalled cars.
