Strong southwest to west winds affected all of south-central and southeast Wisconsin on May 5th.  Maximum wind gusts were 39 to 45 knots (45 to 52 mph).  Small trees were knocked down or tree limbs were broken.  Some of these fell on power-lines resulting in scattered power outages, especially in the counties of Green Lake and Columbia.   The strong winds were generated by a deepening low pressure over Lake Superior moving eastward.  The atmosphere mixed all the way up to 8 to 10 thousand feet above the ground which allowed for the mixing down of higher momentum air to the surface.  The strong winds affected the nearshore waters of Lake Michigan east of Sheboygan to Kenosha, but no damage was reported.
Three Fitchburg (Dane Co.) police officers were injured (direct injury) when they were hit by an 8-foot-by-8-foot section of wall that was wind-blown off a trailer being used for training purposes.  In the Township of Albion (southeast Dane Co.) a man-made debris fire got out of control when the wind pushed the flames onto a nearby barn.  The barn and contents were a total loss.  Inside the barn were stored 5 boats, 3 classic cars, farm machinery, and tools.  The barn and contents loss (estimated at $300,00) would be indirectly related to this strong wind event.  Consequently, the $300K in damage is not part of the $240K in property damage listed in the header strip of this strong wind event.  Elsewhere, it was assumed that there were at least a couple power-lines down in each county listed in this event (loss of $10K), and damage amounts are estimated.
