The Storm Prediction Center says there is a SLIGHT RISK of severe thunderstorms overnight over southwestern Iowa, and a MARGINAL RISK of severe thunderstorms over the rest of Minnesota, the rest of Iowa, the northwestern quarter of Illinois, and the western third of Wisconsin (west of a Hurley to Medford to Madison to Beloit line). Warm and increasingly humid air over Iowa and Minnesota will move eastward toward Wisconsin and Illinois. A cold front will move into western Minnesota and Iowa triggering thunderstorms that will move eastward toward Wisconsin and Illinois. An isolated severe thunderstorm is possible with high winds, hail, and heavy rainfall.

An isolated severe thunderstorm with high winds, hail, and heavy rainfall may be possible. A few thunderstorms may develop in the afternoon, with a very slight chance of a severe thunderstorm developing; the main threat will be high winds and hail.
