Inclement weather began having a more significant effect at O’Hare and Midway airports in the early evening. The average delay at O’Hare was 38 minutes, and 16 flights had been canceled by 5:15 p.m., according to the Chicago Department of Aviation. Only one flight was canceled out of midway, and the average delay was 37 minutes.

Sunday’s snowfall should begin to taper off in the evening, the weather service said. About the same time, temperatures are expected to dip from the 20s into the teens, with wind chills moving into the single digits.

The weather service warned that drivers should continue to use caution as many roadways are expected to remain covered in snow into the night, causing dangerous travel conditions and visibility issues. The Illinois Tollway deployed its full fleet of 196 snowplows to combat the potentially hazardous conditions.

The last time it snowed on Christmas Eve in Chicago was in 2013, when the area saw less than half an inch accumulate. The most snowfall the Chicago area has seen on Dec. 24 was in 1918, when more than 7 inches of snow accumulated.

Christmas Day could see some additional flurries or a small amount of accumulated snowfall, the weather service said. In addition, increasing winds and temperatures that could reach negative wind chills are expected to continue through the Sunday from overnight.
