Is Penn Manor School District closed tomorrow?

The card above shows tomorrow's chance that Penn Manor School District closes or delays school, from tonight's National Weather Service forecast for the district's area. It is an estimate; only the district can announce a closure, usually on its website, by text or phone alert, and through local TV and radio.

There is no fixed number: the district weighs snow totals, ice, wind chill, road crews and timing. Our model treats about 6 inches of overnight snow as the level where closures become likely around ZIP 17551, which averages 21 inches of snow a year (NOAA 1991–2020 normals).

Districts usually decide early in the morning, after crews check the roads, and sometimes the evening before when a big storm is certain. Check the district's official website and alerts for the decision; we don't report official closings.
