EF1 tornado in Dane County, Wisconsin

An EF-1 rated tornado developed south of Marshall near Highway 73, proceeding northwestward, damaging several farms and large areas of trees, before dissipating on the south side of Waterloo.

Severe thunderstorms developed across western Wisconsin and moved eastward across southern Wisconsin through the afternoon and evening hours on June 22nd due to passing low pressure and its approaching cold front. There were supercell thunderstorms along with bowing segments along this line which lead to multiple areas of damage. Two strong tornadoes occurred, which were rated EF-2 near Argyle and through the south side of Janesville. Many reports of flash flooding were received due to torrential rainfall and slow storm movement or the training of thunderstorms. One of the other issues for this event was that it occurred on a Saturday evening where numerous large events were occurring which ended up cancelling or postponing to a later date.
