How Accurate Is Our Calculator?

Our Snow Day Calculator has been refined over many years to deliver highly accurate predictions. By combining data from the National Weather Service with our proprietary algorithm, we account for:

  • Real-time weather forecasts
  • Regional snow removal capabilities
  • School district policies and history
  • Weather patterns specific to your area
  • Timing of precipitation
  • Temperature and wind conditions

While no prediction tool is perfect, our calculator typically achieves 85-90% accuracy for predictions made within 24 hours of potential snow events.

Tips for Using Our Calculator

Check Forecasts Regularly

Weather forecasts become more accurate as the event approaches. Check back within 12 hours of a potential snow event for the most accurate prediction.

Provide Accurate School Information

The calculator considers your school type and district history. Be accurate about previous snow days used and district leniency.

Use Your ZIP Code

Weather conditions can vary significantly even within a small area. Using your exact ZIP code ensures the most relevant forecast data.

Remember: Nothing is 100% Certain

Always check your school's official announcements. Our calculator is a prediction tool, but the final decision rests with school administrators.
