Snow will develop across the Chicago area this afternoon and evening, followed by sharply colder and blustery conditions that may impact New Year’s Eve travel and outdoor celebrations.
According to the National Weather Service Chicago office, precipitation is expected to begin midday, possibly starting as rain or a rain-snow mix before changing to snow. Accumulations are forecast to reach up to 1 inch, with the highest likelihood of measurable snowfall north of Interstate 80. While totals are light, brief bursts of snow could reduce visibility during the afternoon and early evening.
Northwest winds of 12 to 22 mph, with gusts up to 28 mph, will accompany the system. As a strong cold front moves through this evening, temperatures will fall quickly from the 20s into the teens. By midnight, most of northeast Illinois will see wind chills near zero, with some northern areas dipping to -5 degrees.
Road conditions may deteriorate during the evening commute and late-night travel hours, particularly on major routes including I-90, I-94, I-290, I-294, I-55, and I-80. Slippery bridges, reduced visibility, and sudden temperature drops could lead to hazardous driving conditions.
Snow is expected to taper off early this evening, but cold and blustery conditions will persist into New Year’s Day. Thursday morning wind chills will remain near zero, with afternoon highs only reaching the upper teens to mid-20s. Conditions gradually moderate heading into the weekend, with dry weather expected Friday through Sunday.
The National Weather Service advises residents to slow down while driving, allow extra stopping distance, and dress in layers if attending outdoor New Year’s Eve events. Exposed skin can become uncomfortable quickly in near-zero wind chills.
This system marks the final weather event of 2025 for the region, with calmer but cold conditions expected to start 2026.
