It looks like we may need our snow shovels come Monday morning.
The National Weather Service has issued a winter weather advisory for snow beginning at 10 p.m. Sunday through midday Monday, with 3 to 5 inches expected along a line north of Rockford to Chicago, which includes Elmhurst. Chance of snow is 100 percent during the overnight hours, and temperatures will hold steady overnight at about 18 degrees, according to the weather service. Light snow showers may continue through Monday afternoon.
The weather service says the storm system is well-organized and reminiscent of an Alberta clipper, a rapidly moving low-pressure system out of Canada that sometimes affect the upper Midwest and the Great Lakes region.
This one will bring snow to north-central and northeastern Illinois, as well as far northwest Indiana, according to the weather service. While snowfall in northern Illinois is expected to be 3 to 5 inches, with the greatest snowfall expected from Rockford to Chicago, south of that line, the amount of snowfall greater than 3 inches could drop off sharply, the National Weather Service said.
The National Weather Service advisory states that snowfall rates of as much as an inch an hour are possible at times, producing rapid snow accumulations on roads. The greatest intensity is expected between 11 p.m. Sunday and 4 a.m. Monday from Rockford to Marengo, and from 3 to 8 a.m. for the central and northern areas of the Chicago metro area.
A winter weather advisory for snow means the snowfall will cause travel difficulty, possibly during the Monday morning rush. Motorists should be prepared for snow-covered roads and limited visibility.
Light snow is possible again on Tuesday, with temperatures nearing 30 degrees.
