The episode as NWS MKX wrote it up.

An isolated microburst generated by a severe thunderstorm resulted in tree or structural damage on seven properties on the northwest side of the city of Verona in the pre-dawn hours. One shed was destroyed a shed, and one home sustained minor roof damage due to toppled trees. In addition, a couple backyard decks and a free-standing wooden swing-set were damaged. Based on newspaper pictures, maximum wind gusts were probably in the 61 knot range (70 mph), and damage was estimated at about $5,000. The severe thunderstorm followed two rounds of severe weather that occurred over parts of south-central and southeast Wisconsin on September 7, 2001.
