A cold front is expected to bring the first snowfall of the 2025-26 winter season to the Chicago area, with wind chills dropping into the teens early next week.
Temperatures will remain in the 50s and 60s through Friday and parts of Saturday. By Saturday evening, the cold front will arrive, dropping temperatures into the 30s across much of Chicago.
Rain is forecasted to move into the area on Saturday and may transition to a mix of rain and snow. According to the National Weather Service, no significant snowfall is expected—only about half an inch.
“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 National Weather Service.
There is a 60 to 70 percent chance of snow on Sunday morning, though it is not expected to have much impact.
Highs on Sunday are expected to reach the mid-30s, with winds blowing at 15 to 25 miles per hour and gusts up to 30 miles per hour.
“It’s going to be a cold, windy, blustery day on Sunday,” Sullivan said.
By Monday morning, wind chills in the Chicago area could feel as low as 10 to 15 degrees above zero.
