During the late morning of May 12, 2000, a single "high-precipitation" supercell thunderstorm developed in west-central Wisconsin, and moved east across the southern four counties of the NWS Green Bay forecast area. Hail up to the size of baseballs, driven by winds in excess of 60 mph, produced incredible damage in Waushara, Winnebago, Calumet, and Manitowoc counties. Chilton and St. Nazianz were particularly hard-hit by very large hail hail and hurricane force wind gusts well over 75 mph. Total damage from the storm in Wisconsin was nearly $122 million, much of that in the NWS Green Bay forecast area.
