The National Weather Service has issued a dense fog advisory for the Chicago area through Wednesday evening ahead of a cold front moving across the state.
The advisory includes Cook, DuPage, LaSalle and Kendall counties, and will expire at 6 p.m., according to the weather service.
The fog is expected to gradually decrease by late afternoon, with scattered showers possible before then. Visibility could be less than a quarter mile along Lake Michigan, and could fall to zero at times, according to the weather service.
And we should enjoy the warm temperatures—in the 50s and even low 60s Wednesday—because the high temperature Thursday is only expected to reach about 35 degrees.
A cold front moving in Wednesday evening will drop temperatures through the weekend, and could bring light snow accumulations Sunday night, according to the weather service.
