Chicago, IL – The National Weather Service in Chicago warns of a powerful winter storm expected to bring substantial snowfall and hazardous travel conditions through tonight.
Snowfall will intensify during the evening commute, especially northwest of I-55 and I-94, with additional accumulations. Drier snow and gusty northwest winds up to 45 mph could cause significant blowing and drifting snow, making travel difficult for high-profile vehicles southeast of I-55.
A Winter Storm Warning and Advisory are in effect until early Wednesday, with concerns for flash freeze and black ice tonight. Residents are advised to check road conditions before driving and to prepare for lingering impacts to the Wednesday morning commute. Another intense winter storm is likely from Friday into Saturday morning, with potential heavy snow and strong winds. The probability of impactful snowfall is increasing, though exact snow accumulations remain uncertain.
A frigid arctic air mass will sweep in early next week, bringing the coldest temperatures of the season next week, with the likelihood of single-digit highs and sub-zero lows. Wind chills could drop below -20°F, raising concerns for ice jams near rivers.
While exact temperature and wind chill values are yet to be determined, the advice is to stay informed and plan for the potential cold weather impacts. For continuous updates, visit weather.gov/Chicago.
