Springfield, Illinois — A sharp return to dangerous winter weather is expected to impact central Illinois beginning Friday, with arctic cold followed by a chance for accumulating snow over the weekend.
According to the National Weather Service in Lincoln, temperatures will drop rapidly by Friday morning as strong north winds usher in an arctic air mass. While record lows are not expected, wind chill values are forecast to fall between 15 and 25 degrees below zero from Friday into early Saturday, creating potentially life-threatening conditions for anyone exposed for extended periods.
Forecasters say high temperatures Friday and Saturday are expected to remain in the single digits to near 15 degrees, with overnight lows falling well below zero. The cold will persist through the weekend before gradual moderation early next week.
In addition to the cold, forecast models show an increasing chance for accumulating snow on Saturday, especially across areas near and south of Interstate 72. While details remain uncertain, the National Weather Service notes higher probabilities for measurable snow across parts of central Illinois as the storm track shifts slightly north.
Even minor snowfall could lead to slick road conditions due to the extreme cold, which reduces the effectiveness of road treatments. Travel impacts are possible on I-72, I-55, and surrounding state highways, particularly during Saturday and Saturday night.
Officials urge residents to prepare now by limiting time outdoors, dressing in layers, and ensuring vehicles are winter-ready. Extra caution is advised for drivers, as cold temperatures can lead to rapid icing and increased risk of breakdowns.
For commuters, students, and weekend travelers, the most hazardous conditions are expected early Friday due to extreme wind chills, with additional travel concerns possible Saturday if snow develops.
