Overview

During the late afternoon and evening of August 23rd, a warm front lifted north through central Wisconsin. At the same time, a strong upper level disturbance was moving across the Upper Midwest and northern Great Lakes. These two features combined to generate scattered severe thunderstorms over central Wisconsin that then moved off into east central Wisconsin during the evening.

The storms initially produced large hail, some of which were the size of golf balls near Thorp in the northwestern section of Clark County. As the storms continued to move southeast, a tornado formed near the small community of Chili, WI. (see below)

Shortly after this damage occurred, the storm began to weaken as it moved off into Wood and Jackson Counties. Another storm developed as the first one was dissipating, which tracked across southern Clark County into northern Jackson County. This storm produced walnut sized hail in Neillsville. The storm weakened as it left Jackson County and entered northern Juneau County.
