Cold weather advisory issued for Chicago area as another Arctic blast arrives

As a storm system departs the Chicago area, another blast of Arctic air will send wind chills plummeting overnight and into Monday.

The National Weather Service has issued a cold weather advisory for the entire Chicago area, which will go into effect at midnight and remain effective until Monday afternoon.

Dangerously cold wind chills are expected in the area, potentially dropping to 20-to-25 degrees below zero, according to forecast models.

Forecasters warn that frigid wind chills of that magnitude can cause frostbite on exposed skin in as little as 30 minutes.

The forecasted wind chills have also led to the decision by dozens of schools to switch to e-learning on Monday, including in Joliet, Crete-Monee, Park Forest and numerous other communities.

Chicago Public Schools will remain open however, officials said Sunday.

As for the rest of the week, residents shouldn’t expect much relief from the bitter cold. Temperatures aren’t expected to get out of the teens until at least Saturday, and more light snow could fall on Tuesday and Wednesday, according to the NBC 5 Storm Team.

The result will be a continuing stretch of below-average temperatures, as highs are typically right around the freezing mark in late January in the Chicago area, according to National Weather Service data.
