HAMMOND, Ind. – Parts of Chicagoland quickly transitioned from rain to snow Saturday afternoon.
The change came around 2 p.m. Saturday. Snow began accumulating in areas such as Sandwich, Ill.; Aurora, Ill.; and Geneva, Ill.
The heaviest snow was expected in the Chicago area between 3 and 6 p.m.
A Winter Weather Advisory for 2 to 5 inches of snow is in effect tonight for a good portion of the Chicago area. Heaviest snow will occur closer in and south of the city into northwest Indiana. Farther west and north snowfall will taper off to an inch or two well west of the Fox River Valley.
The advisory is in effect until 6 a.m. Sunday.
With temperatures in the lower 30s, it will be a wet snow initially, but snow will stick and accumulate as readings fall through the 20s this evening and the teens overnight. Winds will strengthen from the north-northwest, gusting over 25 miles per hour, causing some drifting. Roads will become snow-covered and slick with hazardous travel over much of the area this evening into the overnight hours.
As the center of low pressure moves northeast through Indiana into Ohio, passing to our east, snow will begin to diminish from west to east later tonight. Some lake-effect snow showers will probably persist into Sunday forenoon in northwest Indiana. By Sunday morning temperatures will probably range from single-digits far west to the teens closer-in and in northwest Indiana with sub-zero wind chills likely Sunday.
The Chicago Department of Streets and Sanitation has deployed more than 200 snow plow trucks to Lake Shore Drive and main streets, according to a statement by the city.
