The Online Snow Day Calculator fetches live forecast data from Open-Meteo β€” a free, open-source weather API β€” analyzing expected snowfall accumulation, storm timing, wind speed, overnight low temperature, and ice/freezing rain risk. These signals are combined with your school type and snow days already used this year.

Rural schools typically close with far less snow than urban districts. Private and prep schools set higher thresholds; boarding schools almost never close. As the storm approaches, check back every few hours β€” predictions improve dramatically once high-resolution models lock in the storm track.
