Illinois — A sharp winter chill greeted central Illinois early Monday, with frost coating lawns and windshields under quiet, gray skies. The air felt crisp, and sidewalks stayed slick in shaded areas as the first full week of winter settled in across the region.
According to the National Weather Service, temperatures early this morning dipped into the mid-20s around Champaign-Urbana, with light southeast winds adding a subtle bite. Clouds linger through the morning, but gradual warming arrives this afternoon. Highs climb into the mid-40s, helping thaw icy patches, though bridges and rural roads may stay slick longer, especially along I-74 and Route 45.
Tonight remains mostly cloudy and noticeably milder. Temperatures hold near 40 degrees, limiting widespread refreezing. Still, damp pavement could cause isolated slick spots before sunrise Tuesday. Drivers heading out early should allow extra braking distance.
Tuesday brings a brighter, calmer winter day. Sunshine breaks through, pushing highs into the mid-50s. Winds shift northwest but stay manageable, offering decent travel conditions for last-minute errands. By Tuesday night, clouds increase as temperatures drop back into the low 30s, setting the stage for another frosty start.
Wednesday marks a turning point. Clouds thicken, and a chance of light rain develops during the afternoon and evening. Temperatures surge into the mid-50s, well above late-December averages. While snow is not expected, wet roads combined with cold ground could briefly reduce traction after sunset.
Christmas Eve trends mild and mostly cloudy. Highs near the low 60s support favorable holiday travel across east-central Illinois. Even so, winter patterns remain active nearby, and colder air could return quickly after the holiday.
Residents should watch for frost each morning, slow down on slick roads, and stay weather-aware. Winter may feel gentle now, but it rarely stays that way. How cold did it feel where you stepped outside this morning?
