A Rough Timeline of Events Monday
Snow will slowly start to move into the area Monday afternoon, with winter storm warnings taking effect in northern Illinois and winter weather advisories taking effect in areas to the south of the Chicago area.
According to current forecast models, the snow is expected to spread into the Chicago area around 5 p.m., and will become moderate-to-heavy at times.
Areas south of Chicago can expect to see some snow, along with a light, icy precipitation mix, with up to one-tenth of an inch of ice possible in some locations, including Kankakee County.
The big issue with the storm in all areas will be the wind, which will cause limited visibility and hazardous driving conditions. The wind off of Lake Michigan could also cause lake enhancement of the snow, hitting Lake and Cook counties hard.
The snow and precipitation are expected to abate overnight in southern counties, but will likely continue well into Tuesday in Chicago and areas closer to Lake Michigan.
