ALT A graphic showing severe risk and timing is shown. Between 1 and 3 AM, storms affect southwestern Wisconsin southwest of Mineral Point. Between 3 and 6 AM, storms impact the I-90 corridor region. Between 6 and 9 AM, storms impact southeastern Wisconsin. A 1 out of 5 risk is pictured for much of southern Wisconsin, with only general thunderstorms expected for southeastern Wisconsin through Fond du Lac County.
