A major winter storm is set to hit areas south of Interstate 55 in Illinois on Wednesday, bringing a dangerous mix of heavy snow and freezing rain that could make travel hazardous throughout the day. Forecasters warn that road conditions will become especially treacherous, with icy surfaces and reduced visibility impacting both the morning and evening commutes.
What to Expect
The National Weather Service has issued a Winter Weather Advisory for much of southern Illinois, in effect from 6:00 AM Wednesday until 3:00 AM Thursday. Snowfall is expected to be heaviest north of Interstate 72, where 2 to 4 inches of accumulation is likely. South of a Decatur to Danville line, ice accumulation could reach 0.10 inches, creating extremely slick conditions on roads, bridges, and overpasses.
In addition to snow and ice, strong winds will add to the storm’s impact, potentially leading to drifting snow and further reducing visibility. Drivers are urged to avoid unnecessary travel and prepare for slow, hazardous road conditions if they must be out.
How This Will Impact Travel
Commuters should brace for major slowdowns and possible road closures as snow and ice accumulate. Authorities are warning drivers to expect slick highways, icy overpasses, and dangerous intersections, particularly in the early morning and late evening hours.
Safety Tips for Drivers
- Drive Slowly – Icy roads can cause vehicles to slide; reduce speed and drive cautiously.
- Increase Distance Between Cars – Stopping on icy surfaces takes longer, so allow extra space.
- Use Headlights and Stay Alert – Visibility may be limited due to blowing snow.
- Prepare an Emergency Kit – Include blankets, snacks, a flashlight, and a phone charger.
- Stay Updated on Weather Alerts – Check local news and official sources for storm developments.
Community Preparations
Several towns across southern Illinois have declared snow emergencies, putting parking restrictions in place to assist with ploughing and road treatments. Residents should move their vehicles off designated snow routes to help road crews clear streets more efficiently.
What’s Next?
The storm is expected to taper off overnight, but lingering ice and snow could still make Thursday morning’s commute difficult. Temperatures will remain below freezing, meaning icy patches may persist on roads and sidewalks. Travelers should remain cautious and check for updates before heading out.
Officials will continue to monitor the storm and provide updates as needed. Stay safe and avoid travel if possible during the worst of the storm.
