Classes at Chicago Public Schools and most schools in the suburbs are canceled again Tuesday.
Officials with Chicago Public Schools are canceling classes for roughly 400,000 students as subzero temperatures persist.
The National Weather Service in northern Illinois has predicted temperatures overnight Monday into Tuesday to drop as low as 23 degrees below zero.
The nation's third-largest school district also canceled classes earlier this month when a deep freeze settled across much of the country with temperatures and wind chills below zero.

Some local universities canceled classes due to weather as well.
At Illinois State in Normal, students were told to stay home Monday and Tuesday. Similarly, Northern Illinois called off classes both days.
The Field Museum, the Shedd Aquarium and the Adler Planetarium all will be closed on Tuesday too.
Shedd Aquarium and the Adler Planetarium officials say the facilities plan to reopen Wednesday. Adler Planetarium officials say they'll reschedule Tuesday's previously designated Illinois Resident Discount Day.
Amtrak is running on a limited schedule because of cold weather in central and northern Illinois.
The passenger rail service said Monday that it would cancel more than a dozen trains on Tuesday. Other trains still will be in service.
In a statement, Amtrak officials say the cancelations are aimed at maintaining service but reducing cold exposure to crews, passengers and equipment. Passengers are asked to check their train status.
Wind chills on Monday and Tuesday are expected to sink to 45 degrees below zero in northern Illinois.
