July 1, 2006: Hail in Columbia and Sauk Counties

A broken line of severe storms developed during the evening hours of July 1st as a cold front headed southeast through south-central and southeast Wisconsin. The atmosphere became very unstable during the afternoon as temperatures reached the lower 90s with dew points in the upper 60s. These storms produced large hail (golf ball size near Marquette in Green Lake Co.) and areas of wind damage as they headed across Sauk, Marquette, Green Lake, Columbia, and Fond du Lac counties. Primarily tree damage was reported across these counties in addition to a destroyed barn at a location 1 mile north of Rosendale (Fond du Lac Co.). Two reports of funnel clouds were also noted; one being in Berlin (Green Lake Co.) at 1820CST and the other in Dundee (Fond du Lac Co.) at 1950CST. The thunderstorms diminished in intensity after sunset as instability subsided.
