What Is a Snow Day Calculator?
A Snow Day Calculator is an online prediction tool that estimates the likelihood of school closures caused by severe winter weather. By combining local weather forecasts with common school-closing factors, it generates a simple percentage that tells you your chance of a snow day tomorrow.

- Students & Parents – plan ahead and avoid early-morning surprises.
- Teachers – stay informed about potential cancellations.

How Does the Snow Day Calculator Work?
Our snow day predictor uses advanced models to analyze real-time weather data from multiple trusted sources, including snowfall chances, snow storm conditions, and temperature forecasts. We built a powerful algorithm specifically to calculate your chance of a snow day, so you can plan with confidence.
- 🌨 Snow Accumulation – heavy overnight snow often means cancellations.
- ❄️ Ice & Freezing Rain – dangerous road conditions trigger school closures.
- 🌡 Temperature & Timing – snowstorms hitting during early morning hours are most disruptive.
- 💨 Wind & Visibility – strong winds and white-outs increase safety risks.
- 🏫 Local Policies – some school districts close earlier than others.
These factors are analyzed alongside historical accuracy data to give you a percentage chance of school being closed in your area.
What We Consider:
- Total snowfall in centimeters
- Conditions like blizzards or ice storms
- Below freezing temperatures
- Weather alerts or wind speeds
- School-specific closures in your region (where applicable)
- Typical winter months: November to April
