No guarantee
We work to keep the formulas correct and publish them at how we calculate, but the site is provided as is. The snow day chance is an estimate built on a public forecast and a published model; it is not a school announcement. Check your district's own channels before you act on it.
The site is not affiliated with the National Weather Service or any school district.
