The Chicago area is set to experience a significant weather shift this weekend, transitioning from unseasonably warm temperatures on Friday to much cooler conditions on Saturday and Sunday. Forecasters predict a mix of rain and snow, with the possibility of light snow accumulation in the evening and overnight hours.

Why it matters

The sudden change in weather patterns will impact daily routines and travel plans for Chicago residents, who may need to adjust their activities and prepare for potential slick road conditions.

The details

After a warm start to the day on Friday with temperatures reaching 65 degrees, a cold front will move in overnight, causing temperatures to plummet into the 30s by Saturday morning. Cloudy skies and the potential for light rain or snow showers are expected throughout the day on Saturday, with highs only reaching the mid-30s. As temperatures drop below freezing in the evening, there is a chance of a light dusting of snow, which could lead to slick roads. On Sunday, the possibility of lake-effect snow showers remains, although the Chicago area may be missed depending on wind shifts.
