The Snow Day Calculator Predictor Tool is an online resource that estimates the chances of school closures or delays during winter storms. By using local weather data—such as snowfall amounts, temperature, and storm timing—the tool generates a percentage predicting the likelihood of a snow day. Students, parents, and teachers often use it for a quick, fun way to see if bad weather might impact the school schedule. While it isn’t always exact, it offers an easy and entertaining way to check snow day possibilities.
