A winter storm is expected to move into the Chicago area Tuesday afternoon and could drop up to six inches of “wet and heavy” snow on portions of the Chicago area.
Rain is expected to change to snow Tuesday afternoon, and heavy snow could affect the evening commute, according to the National Weather Service.
The snow is expected to stop by 9 p.m., but three to six inches of new accumulation are possible by then, the weather service said.
The heaviest snow is expected north of Joliet, with two to four inches possible in the south suburbs.
The storm could be the largest of the season, although the weather service cautions that there is a higher than usual amount of uncertainty in forecasting accumulations for this storm. Last Friday’s storm produced 2.7 inches of snow at O’Hare International Airport, tying this season’s largest snowfall.
A winter storm watch will be in effect from Tuesday afternoon through Tuesday evening. The watch means there is a potential for significant snow, sleet or ice accumulations that could impact travel.
Wind gusts up to 40 mph could create low visibility, making travel difficult, according to the weather service.
The weather service is predicting a chance of snow on Wednesday and Thursday that could produce up to an additional two inches of accumulation.
