Chicago has seen 17.1 inches of snow over the last few weeks, making it the fastest start to the city’s snowfall season since 1978 — when more than 24 inches fell before Dec. 7 — according to NWS data.
The cumulative snowfall is also nearly matching all of the snow the city saw last season at 17.6 inches.
The NWS recorded 4.6 inches of snow at O’Hare and 4.3 inches at Midway airport between midnight Sunday and noon.
Overnight Sunday, temperatures will dip below zero. But warmer temperatures will return this week.
Monday is forecast to be partly sunny with a high of 25. The high Tuesday and Wednesday will be 38, warm enough to melt some of the snow on the ground. A chance of snow returns Thursday and Friday when highs will be in the upper-20s.
Colder weather is set to return by the end of the week, with Thursday and Friday nights’ lows predicted to be in the single digits and Saturday’s high to be 14 degrees, according to the weather service.
The additional snow on Sunday adds to an already snowy season, when the area recorded the most snow on any November day on record last month.
