It would have to be quite a stress to crack a double or triple glazed modern window.Another possibility {though unlikely} is the sash has warped/pulled away from the glazing and water entered between the two ... that water has since frozen and the pressure has cracked the glazing.I'm sure it's not been as cold in Philly as we regularly experience (today is the first day warmer than 0F in a month) and the cold never makes the glass crack here ... especially in a modern thermo-pane.
