Pittsburghers awoke to bitter cold and wind chills this morning that caused a handful of school districts to delay classes.
The reported low of 10 degrees shortly before 8 a.m. wasn't close to the record low for the date of minus-5 degrees set in 1962. Today's forecast high of 18 degrees is less than half of the normal high of 40 degrees for the date.
A veritable heat wave is in store, with a high of 31 expected Friday and 36 on Saturday. But snow and freezing rain are expected to cross the region Friday night into Saturday, according to the National Weather Service.
