About 23.8 inches a winter at a NOAA weather station under a mile away, averaged over 9 winters. Between December 1 and March 31 that brings 3 weekday mornings a year with 2 inches of new snow or more, and 1.2 with 4 inches or more.

13.5 inches on March 14, 2017, the largest single day at a NOAA weather station under a mile away in 9 winters. The snowiest winter was 2018 to 2019, with 36.3 inches.

Pennsylvania requires either 180 days, or hours: 900 for kindergarten through grade 6 and 990 for grades 7 to 12, as the district chooses. The state forgives no days; districts are expected to build make-up days into the calendar for closures beyond any Flexible Instructional Days.
