Overview
Moderate to heavy rainfall impacted southern Wisconsin evening Monday evening into Tuesday, with light icing towards central Wisconsin. The rain brought widespread flooding to portions of southern Wisconsin, as the water had very little place to go given the frozen ground. Area rivers swelled out of their banks as well, with some reaching moderate flood stage or higher. Slick stretches of roadway continued into Wednesday as temperatures dropped below freezing area-wide.Rain and Ice
