The snowy conditions slowed traffic during the Monday evening commute. IDOT spokesperson Jae Miller said there were 100 salt trucks on the roads Monday night salting bridges, overpasses and roadways as needed.
The precipitation began as rain during the mid-afternoon over northeast Illinois and northwest Indiana, but began transitioning to snow across the northwest suburbs, including Arlington Heights and Woodstock on Monday afternoon. The fast-moving system dropped anywhere from a half-inch to 3 inches across the Chicago area.
"It's starting to move out as quickly as it moved in, but not before it dropped 2 inches in Joliet, about 1.5 inches in Highland Park, 0.5 inches in Crown Point," said ABC7 Meteorologist Jerry Taft.
Temperatures Monday evening dropped dramatically after a weekend that saw the season's first 80-degree temperatures.
The chill will continue Tuesday before temperatures start to edge closer to the seasonal high of 58 degrees, according to the weather service.
