Probability of Snow Day

FAQ

How is the snow day probability calculated?

We use National Weather Service (NOAA) data (snowfall, precipitation chance, and winter alerts) and apply a transparent heuristic to estimate the chance of a closure. It is an estimate, not an official decision.

Which areas are supported?

United States only, because we rely on NWS/NOAA. Results outside the US are not supported.

Do you store my location?

No. Your location/ZIP is used only to fetch weather and compute your result in real time.

Is this free?

Yes. It is free to use. We may support it with ads later, but ads are currently disabled.

What if the result seems wrong?

This is an estimate. Always check your school district's official announcements.
