Chicago, IL – Residents across Chicago and much of northern Illinois should prepare for dangerously cold conditions overnight into Monday morning, with wind chills dropping as low as 25 degrees below zero in some areas.
According to the National Weather Service Chicago, a Cold Weather Advisory remains in effect from 3 a.m. to 10 a.m. CST Monday, impacting large portions of central, east-central, north-central, and northeast Illinois. Forecasters warn that the combination of frigid temperatures and strong winds will create hazardous conditions for anyone outdoors during the early morning hours.
The advisory includes Cook, DuPage, Will, Lake, McHenry, Kane, Kendall, DeKalb, La Salle, Grundy, Kankakee, Livingston, Boone, Ogle, Lee, and Winnebago counties, affecting cities such as Chicago, Evanston, Naperville, Joliet, Waukegan, Schaumburg, Rockford, Aurora, Elgin, Oak Lawn, Orland Park, and DeKalb.
Wind chills are expected to fall between 20 below zero and 25 below zero, cold enough to cause frostbite on exposed skin in as little as 30 minutes, according to the NWS. Early commuters, overnight workers, and anyone waiting outdoors for public transportation are considered especially at risk.
Officials urge residents to limit time outside, dress in multiple warm layers, and wear hats, gloves, and face coverings to protect exposed skin. Extra caution is advised while traveling, particularly during the morning commute when temperatures will be at their coldest.
This blast of Arctic air is expected to ease later Monday morning, but residents should continue monitoring local forecasts for any updates or additional advisories.
