Chicago (CBS) — The Chicago area is under a winter storm warning through Saturday afternoon, with heavy snow accumulations of up to eight inches expected in some areas.
The heaviest accumulations are expected overnight Friday into Saturday morning, with storm prediction models showing some areas getting up to 8 inches of snow overnight.
Areas south of Chicago could see 3 to 7 inches, while northern areas could see slightly higher totals, around 4 to 8 inches.
By noon on Saturday, the snow is expected to move out while frigid air moves in.
Winds will blow and drift the snow on Saturday, with gusts reaching up to about 30 MPH in some areas.
Those gusty winds will create dangerous conditions on Lake Michigan, where waves could reach 7 to 10 feet. A Lakeshore Flood Advisory is in effect from 6 a.m. Saturday to 9 a.m. Sunday.
Around 9 p.m. Saturday, lake-effect snow is expected to start. That round of snow could ramp up overnight, bringing an additional 2 to 6 inches to areas near the lake.
An arctic blast will take over on Sunday, bringing bitter cold and wind chills well below zero.
CBS 2 has a timeline of the winter storm:
