A strong cold front swept into southwest Wisconsin during the mid morning hours.  A narrow line of severe thunderstorms developed immediately ahead of the cold front.  The storms caused strong winds aloft to reach the surface, resulting in damage to trees and power lines.  At least 8,000 customers lost electrical power due to the storms.  Thunderstorm winds ripped the tin roof from a barn in Marinette county and downed a shed near Freedom (Outagamie co.).  More than 100 trees were downed by thunderstorm winds near Alice Lake (Lincoln co.).  Two cottages were destroyed and six others were damaged when trees landed on them.  One person sustained a minor injury when a mobile home was flipped on its side by thunderstorm winds 5 miles east northeast of Tomahawk (Lincoln co.).A waterspout developed over the southern part of Green Bay and moved north along the shoreline before it dissipated.
