A mostly dry and mild winter was relegated to a distant memory when a snowstorm battered the area this weekend — but the weather isn’t done with its one-two punch just yet.
Forecasters say northern Illinois is in for the coldest night of the season so far Sunday into Monday, with the wind chill factor making it feel as cold as 20 below in some places, according to the National Weather Service. Even the “actual air temperatures will drop below zero,” the weather service warned in a post on social media Sunday.
The coldest places are expected to be far west and northwest of the city, meteorologists said. Both Dixon and DeKalb could see actual temps as cold as 9 below and a wind chill of 20 below by Monday morning. In the Chicago area, the wind chill might make it feel as cold as 5 below.
The cold will be the result of “arctic air” moving into the area. And it isn’t expected to let up much this week, with another blast expected a few days later.
“Arctic air will move into the region behind the departing weather system with wind chills below zero expected Sunday night into Monday morning. Another shot of cold air arrives by early Thursday,” according to the weather service website.
