A long stretch of bitter cold and strong winds is forecast to settle across Illinois beginning Saturday, Feb. 8, resulting in a prolonged period of severe winter weather that could affect travel, utilities, and outdoor safety statewide.
The National Weather Service predicts that recurrent surges of Arctic air will sweep over the Midwest between February 8 and Saturday, February 14. While this is considered a low-risk event, the length of the cold, combined with sustained winds, will cause wind chill values to drop below zero at times, particularly overnight and in the early morning.
Wind chills in northern Illinois, including Chicago and areas along the I-90 and I-94 corridors, are predicted to fall below zero on occasion, making extended outdoor exposure hazardous without suitable winter protection. Central Illinois, including Rockford, Peoria, and Bloomington, will experience prolonged cold stress, with open and rural areas facing harsher wind effects. Southern Illinois may miss the coldest readings, but it will still see below-average temperatures and bitter winds.
During the coldest months, the Illinois Department of Transportation advises drivers to expect hard-starting vehicles, low tire pressure, and icy places on untreated roads. Residents are asked to dress in layers to block the wind, preserve exposed pipes, and check on elderly neighbors and others who do not have reliable heat.
Cold temperatures are likely to linger until February 14, with more wind chill advisories possible if conditions worsen.
