Late-season snowfall possible Monday during evening commute

Snowfall beginning Monday afternoon could snarl the evening commute and drop up to an inch of snow, following a weekend of rollercoaster weather for Chicagoans.

The precipitation is expected to begin as rain during the mid-afternoon over northeast Illinois and northwest Indiana, but will transition to snow later in the afternoon, according to the National Weather Service.

Slushy accumulations on the roadways is possible, and the new snow combined with reduced visiblility could result in slower commute times Monday evening, the weather service warns.

Up to an inch of snow could fall overnight, according to the weather service.

Meanwhile, temperatures could fall to 37 degrees by 5 p.m., dropping 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.
