Chicago, IL – Illinois is bracing for the coldest air of the season as an Arctic front pushes southward, bringing subzero wind chills and single-digit temperatures from Thursday, December 11, through Monday, December 15. The incoming air mass is expected to impact most of the state, including Chicago, Rockford, Peoria, and Springfield, by late next weekend.
According to the National Weather Service, confidence is increasing that the Arctic outbreak will settle over the Midwest, producing morning lows in the single digits and wind chills dipping below zero. Breezy northwest winds could make conditions feel even colder, particularly in northern Illinois.
Despite the intensity of the cold, the system is forecast to remain mostly dry, as storm tracks stay to the south. However, light flurries or brief snow showers may occur, especially across the northern tier.
Residents are urged to take precautions ahead of the weekend chill. Dress in layers, cover exposed skin, and limit outdoor exposure to prevent frostbite. Homeowners should check heating systems and ensure pets have safe indoor shelter.
The frigid conditions are expected to persist through early the following week before temperatures gradually moderate. Officials advise staying tuned to National Weather Service Chicago and Illinois Emergency Management Agency updates for any changes.
