Arizona Winter Profile
Arizona sits in the classic mid-latitude winter belt — enough snow to regularly close schools, not enough to build infrastructure for it. Across the 7 Arizona cities covered by SnowSense™, average annual snowfall is 16 inches. Flagstaff receive up to 90 inches in a typical winter; lower-latitude cities like Phoenix see closer to 0.
School-closure decisions in Arizona often hinge on precipitation type as much as accumulation. Storms that cross the region frequently transition from snow to sleet to freezing rain and back, and the difference between a four-inch snow event and a one-inch ice-glaze event is invisible until the storm arrives. Districts tend to close preemptively when ice risk is in the forecast.
