CHICAGO (WLS) -- The Chicago area got its first deep freeze of the season on Sunday as temperatures dipped into the single digits in much of the area, with wind chills 10 to 15 degrees below zero.
Temperatures are expected to continue to drop overnight with many places, especially in the north and northwest suburbs where temps are expected to drop below zero.
The cold will stay for the next few days with Tuesday possibly being the coldest day of the week.
Snow is expected during the Monday evening commute and into the night. The most significant snowfall is expected between 4 p.m. and 11 p.m. with many areas getting between 1 and 1.5 inches of snow.
This cold snap is the Chicago area's coldest in more than 10 months, said ABC7 Meteorologist Phil Schwarz.
At 10 p.m., the temperature at O'Hare International Airport was 3 degrees with a real feel of -16 degrees.

Sunday night, a few people braved the cold while walking around Maggie Daley Park in downtown Chicago, but no one was on the ice rink.
"It's Chicago. You know, we love the, the snow (laughs), the cold weather," said Abby Trotter, who was out Sunday evening.
The few brave ones said the only way to handle this type of extreme weather is by wearing lots of layers.
