Snow Day Calculator — Will School Be Cancelled Tomorrow?

Our calculator uses real-time weather forecast data from Open-Meteo to estimate the probability of a snow day. It considers snowfall amount, temperature, wind speed, and day of week. While no prediction is perfect, the calculator gives you a data-driven estimate based on conditions that historically lead to school closings.

The main factors are total snowfall (the biggest driver), temperature and wind chill, road conditions, timing of the storm, and whether it falls on a Friday (less likely to cancel) or Monday (more likely). District policies and regional snow tolerance also play a role.

In most regions, 3-4 inches of snow significantly increases cancellation chances. 6+ inches almost guarantees a snow day in areas not accustomed to heavy snow. However, northern states with robust snow removal may need 8-12 inches before cancelling.

Yes, enter any US ZIP code and we will fetch the weather forecast for that exact location. The calculator works for all 50 states.
