CHICAGO (CBS) — A mild and dry start to the day on Monday is giving way to freezing temperatures and light snow during the afternoon.
CBS 2 Meteorologist Megan Glaros reports, while temperatures were in the mid 40s early Monday morning, a cold front brough a blast of cold air, and the mercury will dip to 33 degrees or colder in the afternoon.
Light snow was falling across Chicagoland by midday.
Rain coming in from the north turned to snow as the cold front moved in from the northwest. While some snow might accumulate on grassy surfaces, most of it won’t stick around for long, though it will make for a slick commute during the afternoon rush.
For most of the Chicago area, snowfall should wrap up sometime between 8 and 10 p.m.
However, parts of northwest Indiana could see up to 6 inches of snow cover overnight, mostly from lake effect snow, from Porter County eastward.
There is a lake effect snow advisory for Porter County and a lake effect snow warning for La Porte County in Indiana and Berrien County in Michigan. Up to 5-7 inches are possible there.
Overnight, temperatures could fall to about 24 degrees, rising only to about 33 degrees on Tuesday. Temperatures likely won’t return to the 40s until Thursday, and won’t be back in the 50s until Saturday.
