About Snow Day Score

Snow day predictors have existed for years, and most of them ask you to trust a percentage without explaining anything behind it. We built this site because that felt backwards. A number is only useful if you understand what's driving it, and a tool is only trustworthy if it's willing to show you when it gets things wrong, not just when it gets them right.

What we actually do differently

Our approach is built around named data sources, transparent explanations, and publicly tracked outcomes. First, every data source is named, not vaguely described as "advanced weather modeling."

Second, once the accuracy system is live, predictions will be logged against verified outcomes and published on an ongoing basis, including the misses.

Third, the core prediction tool can be used without providing your name, email address, or creating an account, just a city or postal code, because a snow day check shouldn't require a sign-up

Why we publish our reasoning, not just a number

A percentage on its own doesn't help anyone plan. Every result on this site comes with a plain explanation of which specific factor is driving it, whether that's an overnight snowfall total, an incoming ice storm, or a wind chill drop past a known danger threshold. Our full methodology page goes into complete detail for anyone who wants to see exactly how an estimate is built.

Who this is built for

Parents planning childcare the night before a storm. Students hoping for a snow day and checking obsessively. Teachers deciding whether to prep a backup lesson plan. School staff weighing the same forecast their district is. We built this to serve all four of those groups honestly, without selling any of them an inflated sense of certainty.

A commitment to accuracy over confidence

We could market this tool as "the most accurate snow day predictor available" without ever showing evidence behind that claim. Instead, our plan is to publish a real, dated accuracy record once it exists and let it speak for itself, including in the seasons it shows an estimate getting something wrong.

If you're a district administrator willing to share your district's actual closure thresholds, we'd genuinely like to hear from you, since real, named policy data is what makes this whole site more useful than a generic percentage

1Who runs SnowDayScore?
This site is built and maintained by a small team focused on winter weather planning tools. Full methodology and data source details are available on our methodology page.
2Do you sell or share user data?
No. The tool only uses the city, ZIP code, or postal code you enter to look up local weather data. No account, name, or email address is required or collected for that purpose. See our Privacy Policy for full detail.
3Can I suggest a correction or share district data?
Yes, through the contact page. District-specific policy information is especially valuable and will be added to the relevant page with a citation to your district.
