CPS School Closings Over: Chicago Public Schools To Reopen On Friday

It's back to school tomorrow for over 400,000 students in Chicago, as the city's school system announced that it will reopen after back-to-back snow days.

Chicago Public Schools' interim CEO Terry Mazany made the announcement late Thursday morning, saying that he believes it's safe to return to classes. A few schools in the system still don't have power, according to the Chicago Tribune, but CPS is working with Commonwealth Edison to restore service.

School buses won't run until Monday, the Sun-Times reports, a potential problem for the tens of thousands of students who ride the bus every day.

The district was closed due to the massive blizzard that dumped more than 20 inches of snow on the area Tuesday and Wednesday. It was the first time city schools were closed due to weather since an equally severe storm hit in the winter of 1999.
