Illinois drivers face slick patches and shifting spring conditions within hours as temperatures swing from near freezing to windy warmth by midweek. Wet pavement and a brief rain-snow mix could create isolated slick spots late tonight, especially on bridges and ramps across the Chicago metro.
According to the National Weather Service, Chicago Midway reports highs near 49°F today with northwest winds up to 25 mph. A 20% chance of rain and snow develops late tonight as temperatures dip to around 29°F. That setup raises a localized flash-freeze risk on untreated roads before sunrise.
By Tuesday, skies clear with a cooler high near 38°F, then clouds build again into the evening. The pattern flips fast by Wednesday as temperatures jump to 63°F with south winds gusting near 30 mph. Expect blowing debris and difficult handling for high-profile vehicles on I-55, I-90, and Lake Shore Drive.
Showers become more widespread by Thursday with a 50% chance and highs reaching 65°F. Wet roads and reduced visibility could slow the afternoon commute. Showers likely continue into Thursday night before tapering Friday, when highs settle near 52°F.
Plan extra time if traveling late tonight or during Thursday’s rain. Keep headlights on in showers and watch for sudden slick spots early.
