Snow Day History in Iowa

Will schools close in Iowa tomorrow? Live snow day probability for 9 Iowa cities, updated every 30 minutes.

Iowa Winter Profile

Iowa sits in the classic mid-latitude winter belt — enough snow to regularly close schools, not enough to build infrastructure for it. Across the 9 Iowa cities covered by SnowSense™, average annual snowfall is 32 inches. Dubuque receive up to 40 inches in a typical winter; lower-latitude cities like Iowa City see closer to 26.

School-closure decisions in Iowa 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.
