Snow Day Calculator for Pennsylvania

Enter your ZIP code above for your district's chance of a closure or delay tomorrow, or pick a city below. Each district decides for itself; the calculator estimates the chance from tonight's National Weather Service forecast and updates hourly from the afternoon until morning.

It depends a lot on where you are: average yearly snowfall across Pennsylvania ranges from 4 to 224 inches (NOAA 1991–2020 normals at weather stations near 1,833 ZIP codes). Among the largest places, Erie averages 104 inches.

It varies by district and by how often each area gets snow. In the snowiest parts of Pennsylvania, closures usually take several inches overnight; in places that rarely see snow, an inch or two can close schools. The calculator scales each storm by the local NOAA normal for your ZIP.
