CHICAGO — Schools closed and warming shelters opened in Illinois as bitterly cold subzero temperatures moved into the state.
The National Weather Service says highs on Wednesday in northern Illinois will be from -4 to 2 with wind chills as low as 30 degrees below zero. The temperature on Wednesday morning in DeKalb was -2 with a wind chill of -19.
The weather service has a wind chill warning in effect from the Wisconsin state line south to Quincy, Lincoln, Champaign and Danville. The rest of the state is under a wind chill advisory.
In response, dozens of schools districts, including Chicago Public Schools, canceled Wednesday classes. Illinois Tollway officials activated road patrols to help stranded motorists.
The weather service says "dangerously cold" wind chills are expected to continue through Thursday morning.
