Tennessee snow day questions
Will schools in Tennessee 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 Tennessee?
It depends a lot on where you are: average yearly snowfall across Tennessee ranges from 0 to 48 inches (NOAA 1991–2020 normals at weather stations near 638 ZIP codes). Among the largest places, Knoxville averages 5 inches.
How much snow closes schools in Tennessee?
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.
