How Our Snow Day Tools Work

As described earlier, we have three types of tools to help you identify the next snow day. Let’s dive into the details of how they work!

Snow Day Predictor

The first tool in your arsenal is our global snow day prediction tool, which helps you calculate the snow day percentage quickly and automatically anywhere in the world. Just enter your ZIP code, city or town name, the exact latitude and longitude of your area, and your school or college district policy if available (or leave it set to default). Along with the percentage, it also provides useful information such as:

  • Probability Score (0–100%): shows how accurate the prediction may be
  • Snow Days History: how many times your city has experienced snow days recently
  • 5-Day Weather Forecast: an extended outlook to help you plan ahead
  • Detailed Weather Outlook: today’s forecast at a glance

Manual Snow Day Calculator

This tool is interactive and fun, allowing you to select and control weather variables such as expected snowfall, low temperature, wind speed, ice accumulation, and wind chill, as well as conditions like blizzard warnings or storms during the morning commute. You can also choose your district policy and see how the percentage changes as these factors influence the chances of a snow day.

In simple terms, you play the meteorologist, adjusting the variable sliders or running what-if scenarios to increase or decrease each factor.

Frequently Asked Questions

It uses real-time weather forecasts plus two years of historical snow day data for your area. While no tool can predict with 100% certainty, it provides a reliable probability based on snowfall, ice, wind chill, and timing.

Freezing rain and ice are often more dangerous than snow because they create slick surfaces that are harder to clear and drive on.

School administrators consider safety first, road conditions, bus schedules, storm timing, and active weather alerts like Blizzard Warnings or Ice Storm Advisories.
