Missouri Snow Day Calculator

Missouri sits in the classic mid-latitude winter belt — enough snow to regularly close schools, not enough to build infrastructure for it. Across the 9 Missouri cities covered by SnowSense™, average annual snowfall is 18 inches. St. Joseph receive up to 21 inches in a typical winter; lower-latitude cities like Springfield see closer to 14.

School-closure decisions in Missouri 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.
