Rain, which moved into Chicagoland during the night, will continue through much of the day on Monday. Morning temperatures will remain at or below freezing north and west of Chicago (except along the lakeshore), which will aid in the development of some light freezing rain. During the afternoon, the area of freezing rain will expand southward before precipitation finally ends in the evening. For the days that follow, Chicago will sit on the cold side of the jet stream until late in the week, so precipitation Wednesday will likely be in the form of snow in Chicago, with an ice storm in central Illinois.
So far this season, freezing rain has been reported over many areas of the United States and Canada east of the Rockies, with several traffic fatalities a direct result of ice covered roads. In this pattern, eastern Kansas and western Missouri are vulnerable to ice storms right through Wednesday.
WGN-TV Chief Meteorologist Tom Skilling and the WGN Weather Center staff provide daily coverage of weather in the Chicago area.
