Will schools close in Delaware tomorrow? Live snow day probability for 4 Delaware cities, updated every 30 minutes.
Delaware sits in the classic mid-latitude winter belt — enough snow to regularly close schools, not enough to build infrastructure for it. Across the 4 Delaware cities covered by SnowSense™, average annual snowfall is 17 inches. Newark receive up to 19 inches in a typical winter; lower-latitude cities like Dover see closer to 16.
School-closure decisions in Delaware 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.
