CHICAGO (CBS) — Those who have to work Monday should prepare for slick and treacherous conditions, as a sloppy mixture of rain, snow and sleet makes its way into the area.
CBS 2 Meteorologist Megan Glaros reports with the temperature hovering at 19 degrees in the early morning hours, the system entered with snow falling on all of the Chicago area.
As the Monday morning rush began, the Chicago Department of Streets and Sanitation sent out 75 trucks to plow the city’s main streets and Lake Shore Drive.
A winter weather advisory is in effect until 6 a.m. Tuesday for Lake and McHenry counties and other areas to the west and northwest of Chicago, as well as southern Wisconsin. The snow is expected to develop by mid-morning and continue through mid-afternoon, with a second wave of light snow coming in the evening and continuing to fall until Tuesday morning.
Lake and McHenry counties, the Rockford area, and areas west of DeKalb will likely see 3 to 5 inches out of the system.
For the immediate Chicago area and counties to the immediate west and south, only about 1 inch of snow is expected.
But other problems are imminent. As the rain-snow line moves north and the temperature creeps to the freezing mark, the snow is expected to mix with rain and sleet. Roads may turn icy as due to the wintry mix of precipitation.
South of the Chicago area, rain is expected for much of the day.
The high temperature for the area Monday is expected to reach 35 degrees, with an overnight low of 33. The temperature will drop the freezing mark of 32 degrees on Tuesday, but the mercury will plummet to 15 degrees Tuesday night.
