A powerful winter system is sweeping across Illinois, bringing snow, strong winds, and dangerously cold wind chills that will last through midweek. Forecasters warn of hazardous travel conditions, flight delays, and extreme cold that could pose risks for anyone exposed to the elements.
The National Weather Service has issued winter weather advisories for much of the state, cautioning residents about accumulating snow and icy roads. Wind gusts up to 35 mph will create blowing and drifting snow, further reducing visibility on major roadways.
Snowfall and Cold Temperatures Expected to Grip the State
A mix of light to moderate snow will blanket Illinois, with the heaviest accumulations expected in the northern and central parts of the state. Strong winds will intensify the cold, sending wind chills well below zero.
- Snowfall accumulations of 2 to 5 inches, with isolated areas seeing higher totals
- Temperatures dropping to single digits, with daytime highs struggling to reach 20 degrees
- Wind chills falling as low as -15 to -25 degrees
- Wind gusts up to 35 mph, leading to blowing and drifting snow
Major Areas Affected
- Chicago and Northern Illinois: Expected to receive 3 to 5 inches of snow, with the heaviest accumulation near Lake Michigan
- Rockford and Northwestern Illinois: Strong wind gusts will push wind chills well below zero
- Central Illinois, including Peoria and Springfield: Snow accumulations of 2 to 4 inches with icy conditions expected on roadways
- Southern Illinois: Less snowfall but temperatures dropping into the teens
Travel Conditions to Become Hazardous
With snow and ice accumulating on roadways, drivers are urged to use caution when travelling. Black ice will make roads slick, particularly on bridges and overpasses. Major highways, including I-55, I-57, I-74, and I-80, could see significant slowdowns and dangerous conditions.
- Air travel disruptions are expected at O’Hare International Airport and Midway Airport, with delays and cancellations likely
- Pedestrians should be cautious, as icy sidewalks and untreated surfaces will be slippery
- Power outages may occur, as strong winds and frigid temperatures strain the electrical grid
How to Stay Safe During the Winter Storm
- Avoid unnecessary travel. If you must drive, keep an emergency kit in your vehicle
- Dress in layers and wear hats, gloves, and scarves to prevent frostbite
- Prepare for potential power outages by charging devices and stocking up on batteries, blankets, and food
- Check on vulnerable neighbours and family members, especially those without reliable heating
Cold Temperatures Will Linger Even After Snow Ends
The heaviest snowfall is expected to taper off by Wednesday, but bitterly cold temperatures will remain through Thursday morning. Warmer conditions may arrive by the weekend, though another system could bring additional snowfall early next week.
Officials are urging residents to prepare for dangerous winter weather and monitor updates from the National Weather Service. Those planning to travel should expect disruptions and take precautions against the extreme cold.
