Just in time for the evening commute, a winter storm warning has gone into effect in the north and northwest suburbs for a storm that could dump more than half a foot of snow.
The warning covers Lake, McHenry, Boone, Winnebago and Ogle counties and remains in effect until midnight, according to the National Weather Service.
A less severe alert -- a winter weather advisory -- is in effect for Cook, Du Page, Kane and De Kalb counties until midnight. The weather service says northern Cook County could see 3-5 inches, the city of Chicago an inch or two, and the south suburbs less than an inch.
But the weather service cautions that the snow will be heavy and wet, and could make travel treacherous this evening. Hail was reported in Joliet and Aurora around 2:30 p.m., according to the Chicago Weather Center.
The snow could stick around until next week because temperatures are only expected to rebound to the mid-30s on Saturday and Sunday, he said. Temperatures could rise Tuesday into the mid or upper 50s across the Chicago area, he said.
Elsewhere in the state, southern and central Illinois will see spring-like weather.
"North central (Illinois) will see winter but central and southern will be more like late spring," Friedlein said. "Temperatures in the 60s and 70s, potentially as far north as Champaign, Urbana, and Danville -- a real springlike system coming through."
