After a brief reprieve, plunging wind chills will once again grip Chicago’s suburbs through the overnight hours and into Thursday.
The National Weather Service has issued a Wind Chill Advisory, which goes into effect at 10 p.m. Wednesday night and continues until Thursday afternoon at noon Central.
The advisory covers most of Northeastern Illinois, including McHenry, DeKalb, Kane, DuPage, LaSalle, Kendall, Grundy, Will, and Kankakee counties. Two counties in Northwest Indiana, Newton and Jasper counties, are also part of this advisory.
This Is How Chicagoans Look Braving Below-Zero Wind Chills
According to the NWS, wind chills could fall to 20 to 30 degrees below zero in the overnight hours, and could cause frostbite in as little as 30 minutes to exposed skin.
LaPorte County is also under a Winter Storm Warning until 7 a.m. Eastern time on Friday morning, and a Winter Weather Advisory is in effect for Porter County thanks to heavy lake-effect snow in the forecast.
