Chicago, Illinois – A prolonged stretch of bitter cold and gusty winds is expected to settle across Illinois beginning Saturday, Feb. 8, creating an extended period of hazardous winter conditions that could impact travel, utilities, and outdoor safety statewide.
According to the National Weather Service, repeated surges of Arctic air will move through the Midwest from Feb. 8 through Friday, Feb. 14. While this is considered a slight risk event, the duration of the cold combined with steady winds will drive wind chill values into subzero territory at times, particularly overnight and during early morning hours.
In northern Illinois, including Chicago and communities along the I-90 and I-94 corridors, wind chills are expected to periodically drop below zero, making prolonged outdoor exposure dangerous without proper winter protection. Central Illinois, including Rockford, Peoria, and Bloomington, will also see extended cold stress, with open and rural areas experiencing stronger wind effects. Southern Illinois may avoid the coldest readings but will still see below-normal temperatures and biting winds.
The Illinois Department of Transportation urges drivers to prepare for hard-starting vehicles, reduced tire pressure, and icy spots on untreated roads during the coldest periods. Residents are encouraged to dress in layered, wind-blocking clothing, protect exposed pipes, and check on elderly neighbors and those without reliable heat.
Cold conditions are expected to persist through Feb. 14, with additional wind chill advisories possible if conditions worsen.
