As winds are expected to travel about 25 mph across the Chicago area Sunday, wind chills could plummet to 15 degrees below zero throughout the day.
The National Weather Service issued a hazardous weather outlook to last through Sunday night for portions of northeast Illinois and northwest Indiana, including Cook, Will, Portage and Lake (Ind.) counties.
While temperatures in the Chicago area are expected to be between 12 and 20 degrees, winds should be traveling from the west at 20-25 mph, creating a wind chill that could plunge to 15 degrees below zero, NWS meteorologist Jamie Enderlen said.
Up to a half inch of snow is forecasted to fall Sunday in areas south of Cook County, Enderlen said. But Chicago’s metro area should only get light flurries throughout the day.
A snowstorm that blew through the area Saturday dropped 4.2 inches of snowfall at O’Hare International Airport, Enderlen said.
The city’s full fleet of 287 snow plows and salt spreaders was deployed Saturday afternoon, along with 26 smaller four-wheel drive plows for smaller side streets, according to the Dept. of Streets and Sanitation.
Areas south of the Chicago area saw the heaviest accumulation of snow, Enderlen said. South suburban Homewood got hit with 6.4 inches of snowfall.
