Warmer weather is finally moving into the area, but freezing rain and snow could make for some treacherous driving on Sunday.
A Winter Weather Advisory is in effect for most of Northeastern Illinois and Northwestern Indiana until Monday morning, the National Weather Service says.
McHenry, DeKalb, Kane, and Kendall counties are under an advisory until 3 a.m. Monday, the NWS says. Freezing rain, mixed with sleet and light snow, will lead to a light glaze of ice and dangerous travel conditions, the advisory says.
LaSalle, Grundy, and Livingston counties are also under a Winter Weather Advisory until 3 a.m. Monday.
Another Winter Weather Advisory covers Lake, DuPage, Cook, and Will counties in Illinois, and Lake and Porter counties in Indiana, and will last until 6 a.m. Monday morning.
Kankakee County will also be covered by that advisory, as will Newton and Jasper counties in Northwest Indiana.
Another Winter Weather Advisory has been issued for LaPorte County in Indiana. That advisory will take effect at 9 p.m. Eastern and will stay in effect through 9 a.m. Eastern Monday morning.
The advisory has been issued as the area can expect a wintry mix of precipitation, including freezing rain, through the evening hours. That precipitation is expected to change over to light snow in the overnight hours, with less than an inch of accumulation expected.
Roads are already slick through most of Northeast Illinois because of the weather, and IDOT is advising motorists to be cautious if they’re driving on Sunday night.
The agency says that traveling could be “treacherous” because of the slippery conditions, and advises motorists to drive slowly and to keep supplies, including a cellphone, warm clothes, blankets, and food, in your car while driving.
