The Storm Prediction Center says that there is a MARGINAL RISK of severe thunderstorms for today and tonight for extreme southeastern Iowa, the northern two-thirds of Illinois, and the eastern third of Wisconsin (east of an Iron Mountain, MI to Portage to Darlington line). Scattered thunderstorms may be possible this morning as overnight thunderstorm activity from Minnesota moves through Wisconsin. An isolated severe thunderstorm may be possible, with high winds, hail, and heavy rainfall as the main threats. As a cold front passes through southern Wisconsin and northern Illinois during the day, additional thunderstorms may form along the front this afternoon, mostly likely from Michigan through northeastern Illinois to southeastern Iowa. Isolated severe thunderstorms are possible, with high winds, hail, and heavy rain as the main threats. The severe weather threat should end with the passage of the cold front on Sunday afternoon and evening.
