Springfield, Illinois – Dangerous Arctic cold will continue across Central Illinois through the weekend, with wind chill values repeatedly dropping well below zero during overnight and early morning hours.
According to the National Weather Service Central Illinois, daily wind chills are expected to bottom out between -10 and -15 degrees, with some locations briefly falling even lower before sunrise. These conditions are forecast to persist through Sunday, with only gradual moderation expected early next week.
Forecast minimum wind chill data shows widespread sub-zero readings across communities including Springfield, Bloomington, Champaign-Urbana, Peoria, and Decatur, especially between midnight and 9 a.m. Each overnight period poses renewed exposure risk as cold air remains firmly in place.
The cold will significantly impact travel along major corridors such as Interstate 55, Interstate 72, and Interstate 74, where commuters, early-shift workers, and stranded motorists could face dangerous conditions if vehicles fail or delays occur. The NWS warns that frostbite can develop on exposed skin in as little as 30 minutes at these wind chill levels.
Daytime temperatures will remain below normal, limiting relief even during afternoon hours. While winds may ease slightly at times, cold air persistence will continue to drive hazardous apparent temperatures overnight.
Officials urge residents to take cold weather precautions, including dressing in layers, covering exposed skin, and limiting time outdoors. Pet owners should bring animals indoors, and homeowners are advised to protect plumbing by allowing faucets to drip and monitoring heating systems.
Drivers are encouraged to keep winter safety kits in vehicles, especially when traveling overnight or early in the morning.
This prolonged cold stretch is especially impactful for commuters, students, outdoor workers, and vulnerable populations across Central Illinois.
Residents should continue monitoring updates from the National Weather Service as Arctic conditions persist.
