After Chicago Public Schools canceled classes due to dangerously cold temperatures Tuesday, the district said students and staff will return on Wednesday.

CPS announced classes will be in session for all students Wednesday as the frigid temperatures the city has seen this week have begun to dissipate.

“Our Facilities Team has been working around the clock to ensure that heating systems are working properly in our schools, and to clear ice and snow from sidewalks and parking lots,” CPS CEO Pedro Martinez said in a statement. “We are also working with our vendors to ensure that bus transportation will run smoothly for students when they return to school on Wednesday.”

Martinez said that due to extra instructional days built into the district’s academic calendar, students won’t need to make up Tuesday’s missed instruction.

According to the National Weather Service, wind chills dipped down near -30 degrees Tuesday morning across much of the Chicago area. Those temperatures are expected to rise back between 10 and 20 degrees Wednesday, but the weather service expects periods of “bitterly cold temperatures” through the rest of this week.
