FROM THE SUN PRAIRIE VOLUNTEER POLICE DEPARTMENT:
Starting at approximately 8:00 pm on Tuesday, May 14, 2013, the Sun Prairie Volunteer Fire Department responded with 10 units and 30 volunteer firefighters to twenty three incidents due to high winds caused by a rapidly moving thunderstorm. Assistance was received from the Dane County Sheriff’s Department, Sun Prairie Police Department, Sun Prairie Utilities, Alliant Energy, MG&E, ATC, and mutual aid from the Cottage Grove Fire Department. Damage ranged from electrical wires down to outbuilding collapse on rural farms.
The largest incident, which included transmission lines and poles down along Highway 19, caused more than 1,500 occupancies to lose power for several hours and closure of State Highway 19 and County Highway C (expected until about 6pm). Firefighters assisted multiple utility companies with scene security and ensuring public safety. In all, fire units responded to calls for service for tree limbs down, uprooted trees, roof damage, trees fallen on top of homes, electrical arcing, and other miscellaneous damage. A monetary damage estimate has not yet been determined.

Isolated thunderstorms caused wind damage across parts of southern Wisconsin Tuesday night.
According to the National Weather Service, last night's storms appear to be the result of a heat burst.
Here's a breakdown of a heat burst from the NWS: In a heat burst, all of the water in the sinking air is evaporated before it reaches the ground, and the air begins to warm before it hits the ground. The air rushes to the ground as a sudden burst of hot, gusty wind.
A powerful spring storm knocked down trees and power lines and left thousands without electricity in southeastern Wisconsin.
We Energies worked to restore power to thousands. As many as 17,000 customers were without service at the peak of the storm, but utility crews made significant progress in restoring power by Wednesday morning.
WTMJ radio reports the storm hit Milwaukee, Waukesha, Dodge and Jefferson counties the hardest. One wind gust measured 68 miles per hour in Oconomowoc.
