Colorado snow day questions
Will schools in Colorado 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 Colorado?
It depends a lot on where you are: average yearly snowfall across Colorado ranges from 10 to 389 inches (NOAA 1991–2020 normals at weather stations near 528 ZIP codes). Among the largest places, Lakewood averages 58 inches.
How much snow closes schools in Colorado?
It varies by district and by how often each area gets snow. In the snowiest parts of Colorado, 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.
