A major weather system is expected to bring extreme cold across most of Illinois this weekend, alongside two rounds of heavy snow in the southern region. Simultaneously, northern and central Illinois face an Extreme Cold Warning, with wind chills forecasted to plumet as low as -34°F. These conditions pose a significant risk for frostbite, hypothermia, and infrastructure disruptions.
“We are preparing for extreme weather conditions statewide and urging all Illinoisians to take precautions throughout the weekend to stay safe and warm,” said Governor JB Pritzker. “As we brace for freezing temperatures across the state and heavy snow in Southern Illinois, I have directed IEMA-OHS to deploy resources to ensure local authorities have the support they need to keep roads clear and residents safe. I encourage everyone to avoid any unnecessary travel, follow safety recommendations, and visit Ready.Illinois.Gov for winter storm updates.”
Regional Breakdown of Impacts
- Central Illinois: 2–6 inches of snow expected over a 36-hour period, with dangerously low wind chills.
- Southern Illinois (Heaviest Impact): 6–12 inches of accumulating snow expected through Sunday evening. Wind chills as low as -16°F will accompany the snow, creating a risk of frostbite and hypothermia.
- Northern Illinois: Facing life-threatening extreme cold with wind chills as low as -34°F through Saturday morning.
“Illinois weather can shift at any moment, and the best time to prepare for this weekend’s unpredictable conditions is right now,” said IEMA-OHS Acting Director Theodore “Ted” Berger. “We are tracking two distinct waves of snow and extreme wind chills that will make travel hazardous. If you must be outdoors, dress in layers and limit your exposure. Our teams are in constant contact with local emergency managers to coordinate a swift response for any weather-related disruptions.”
Safety Recommendations for Residents
IEMA-OHS recommends the following actions to stay safe during this event:
- Travel Safety: Avoid travel during peak snow hours. If you must drive, keep a winter emergency kit in your vehicle, including blankets, a flashlight, and water.
- Home Care: Insulate exposed pipes and ensure you have a three-day supply of food and medication.
- Personal Health: Cover all exposed skin when outdoors to prevent frostbite, which can occur in minutes at -34°F.
- Check on Others: Reach out to elderly neighbors or those with disabilities who may need assistance with heating or snow removal.
