Arizona snow day questions
Will schools in Arizona be closed tomorrow?
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.
How much snow falls in Arizona?
It depends a lot on where you are: average yearly snowfall across Arizona ranges from 0 to 90 inches (NOAA 1991–2020 normals at weather stations near 417 ZIP codes). Among the largest places, Tucson averages <1 inches.
How much snow closes schools in Arizona?
Not much. Where snow is rare, districts often close or delay for an inch or two, and for ice. The calculator scales each storm by the local normal, so the same inch counts for more here than in a snowy state.
