With CPS buildings closed Wednesday and Thursday, the district suggested families bring children to Chicago Park District field houses, which are open as warming centers. In response to the school closings, which affect more than 300,000 students, the Park District announced it was offering drop-in centers at many of its parks from 8:30 a.m. to 3:30 p.m..
