Wind Chill in Connecticut

Connecticut sits in the classic mid-latitude winter belt — enough snow to regularly close schools, not enough to build infrastructure for it. Across the 10 Connecticut cities covered by SnowSense™, average annual snowfall is 36 inches. Waterbury receive up to 42 inches in a typical winter; lower-latitude cities like New Haven see closer to 28.

School-closure decisions in Connecticut 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.

Schools in Connecticut typically close for cold alone when wind chills drop below dangerous thresholds. The exact threshold varies by district — urban districts with walking students tend to close at warmer wind chills than rural districts where all students ride buses.
