Visibility in most of the snow-hit areas will be near one-quarter mile, the National Weather Service forecast. The snow is expected to continue through late this evening. Roads will become increasingly hazardous, the agency warned.
A Winter Weather Advisory has been in effect and will remain until 3 a.m. Sunday. Total snow accumulations are expected to be 2 to 4 inches.
Lighter amounts of snow will occur over far northern Illinois. Areas toward the Wisconsin state line may end up with very little snow, according to the forecast.
