It's beginning to look a lot like winter, as the first snow of the season coats the suburbs.
Snow began falling at 11:30 p.m. Friday at O'Hare International Airport, the region's official weather reporting station, said Charles Mott, a meteorologist with the National Weather Service's Chicago office.

"The heavy snow will end right around noon and then there will be flurries for most of the afternoon and into the evening," Mott said.
Residents of LaSalle, Livingston and Ford counties south of the suburbs are receiving the heaviest snow totals from this storm, Mott said. The city of LaSalle had the highest total at 11 a.m. with 6.9 inches, according to the National Weather Service.
A reporting station in St. Charles recorded the most snow in the suburbs, with 4.5 inches, but other locations in the city received only 2.9 or 2.4 inches. Hoffman Estates and Lisle each reported 3 inches at 11 a.m. and Lincolnshire reported 2.5, according to the National Weather Service.
At O'Hare, 1.7 inches of snow had fallen by 11 a.m. According to the Chicago Department of Aviation, 325 flights had been canceled at O'Hare and other flights were being delayed for 30 minutes or more.
This storm, which brought with it moisture from the Pacific Ocean, is dumping heavy, wet snow on the land in its path, Mott said. When snow stops falling, Mott said suburban residents can expect temperatures to drop.
