Chicago, Illinois – A mid-January warm-up is expected to bring periods of rain across much of the Midwest, while increasing the risk of freezing rain and slick travel conditions in colder northern and interior areas as temperatures fluctuate near freezing.
According to the National Weather Service Climate Prediction Center, much of the Midwest is favored to see above-normal temperatures during the January 9–13 period, with precipitation trending near normal. This pattern supports rain across southern and central portions of the region while allowing mixed precipitation to develop farther north where cold air lingers closer to the surface.
The highest risk for freezing rain appears across northern Illinois, northern Indiana, Michigan, Wisconsin, and parts of Ohio, particularly during overnight and early morning hours. Even light ice accumulation could create hazardous travel on major corridors including I-80, I-90, I-94, and rural secondary roads where temperatures remain colder.
Farther south, including Missouri, southern Illinois, Indiana, and Kentucky, precipitation is more likely to fall as rain, limiting snow potential but leading to wet roads and reduced visibility during heavier showers. Brief nighttime cooling could still allow isolated slick spots on bridges and overpasses.
Travelers across the Midwest are encouraged to monitor changing conditions closely and allow extra time for commutes as temperatures fluctuate. Additional advisories may be issued as confidence increases closer to mid-January, especially if colder air lingers longer than expected across northern portions of the region.
