Subzero wind chills are expected to persist overnight near major central Illinois roadways, increasing safety risks for travelers.
According to the National Weather Service Central Illinois office, Arctic cold will continue through the remainder of the week, with overnight and early morning wind chills well below zero through Sunday. A Cold Weather Advisory remains in effect for portions of the region, with the coldest conditions expected during late-night and pre-dawn hours.
Forecast minimum wind chills include -20°F in Galesburg, -17°F in Bloomington and Champaign, and -15°F or colder near Peoria, Decatur, and Springfield. These conditions are expected to impact areas along I-74, I-55, I-57, I-72, and US-34, where early-morning commuters and overnight drivers may face heightened exposure risks.
The Weather Service advises residents to dress in layers, limit time outdoors, and cover exposed skin to prevent frostbite. Wind chills this low can cause frostbite in as little as 30 minutes. Families are encouraged to check on vulnerable individuals and bring pets indoors during the coldest periods.
Vehicle-related issues are also a concern. Officials recommend keeping fuel tanks at least half full, carrying emergency supplies, and ensuring vehicles are winter-ready before traveling, particularly during overnight hours. Drivers along interstate corridors may experience increased risks if stranded due to mechanical problems.
While temperatures are forecast to remain well below normal through the upcoming weekend, forecasters note dry conditions are expected for several days, with a 30% chance of light snow on Sunday. Some moderation in temperatures is anticipated early next week.
Residents should continue to monitor updated forecasts from the National Weather Service as cold weather advisories remain subject to change.
