The extreme cold on Tuesday prompted all nine public school districts in Butler County- and many private schools- to delay the start of classes.
A-C Valley, Butler, South Butler, Seneca Valley, Mars, Freeport, Slippery Rock, Karns City and Moniteau all delayed school by two hours. Butler County Community College operated on a 9:30 a.m. start time for students taking classes on its main campus and all branch campuses.
Temperatures started out below zero on Tuesday, but the National Weather Service is forecasting a high today of 30 degrees.
