Frequently Asked Questions
How does the Snow Day Calculator estimate probabilities?
The algorithm evaluates the primary variables school superintendents and transportation directors assess: total snow accumulation, surface ice/freezing rain presence, morning commute temperatures (which impact salt effectiveness), wind chill/drifting, and local road infrastructure type.
Why does timing of snowfall matter so much for school cancellations?
Snow that falls between 3:00 AM and 7:00 AM coincides directly with school bus driver mobilization and plowing schedules, resulting in much higher closure rates than snow falling during the afternoon or weekend.
Why do rural districts close more easily than urban districts?
Rural districts feature narrow unplowed country roads, hills, and longer bus routes, making bus travel dangerous even with moderate snowfall.
