A cold front is expected to bring the first snowfall of the 2025-26 winter season to the Chicago area as wind chills drop into the teens early next week.
The National Weather Service forecasts no significant snowfall, expecting 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 weather service.
“Probably a 60%, 70% chance of snow there Sunday morning, but it doesn’t really look like it’s going to be too impactful.”
“By the time everybody wakes up Monday morning, wind chills for the Chicago area will probably be like 10 to 15 degrees above zero,” Sullivan said.
Summary: A cold front will bring the first seasonal snow and significantly cooler temperatures to Chicago, with wind chills making Monday the coldest day of the fall season so far.
