A strong cold front is expected to sweep into the Chicago area this weekend, possibly bringing the first snow of the 2025–26 winter season. Meteorologists warn that temperatures will shift sharply as the front moves through.
For much of Friday and part of Saturday, temperatures will remain in the 50s and 60s. By Saturday evening, the cold front should reach the region, pulling temperatures down into the 30s across most of the Chicago area.
Rain is forecast to arrive Saturday and may transition into a mix of rain and snow later that night. The National Weather Service expects only minor accumulation—around half an inch—with most of it limited to grassy surfaces.
“By the time everybody wakes up Monday morning, wind chills for the Chicago area will probably be like 10 to 15 degrees above zero,” said a meteorologist.
“It looks like any accumulation of snow we see Sunday morning will probably be just on grassy surfaces and maybe bridges and overpasses,” said Casey Sullivan, a meteorologist with the weather service. “Probably 60 to 70 percent chance of snow there Sunday morning but it doesn’t really look like it’s going to be too impactful.”
Sunday’s highs are expected to reach the mid-30s with winds blowing 15 to 25 miles per hour and gusts up to 30 miles per hour. Weather officials describe it as a cold, windy, and blustery day.
“It’s going to be a cold, windy, blustery day on Sunday,” Sullivan said.
A sharp cold front will chill Chicago this weekend, dropping temperatures into the 30s and possibly bringing a light snowfall before winter fully arrives.
