Another round of snow is expected to blanket the Chicago area Friday, according to the National Weather Service.
The lake effect snow will likely start about 7 a.m., with the possibility of an inch of snow falling per hour, according to the National Weather Service. Cook County, along with suburban DuPage and Lake counties, are under a winter weather advisory that starts at 9 a.m. and ends at 3 p.m.
The snow could lead to visibility issues for those commuting by car Friday morning, and officials urge motorists to use caution. Temperatures will range from 14 to 19 degrees, with wind chills dipping to minus 10 in the morning, according to the National Weather Service.
A second wave of expected snow has prompted a winter storm watch for Cook County that will start at 3 p.m. Friday and last until Saturday morning. The watch also includes parts of Northwest Indiana.
