The Snow Day Predictor is an online tool that uses historical weather data and statistical analysis to predict the likelihood of a snow day occurring in a particular area based on the zip code or city entered. However, it does not take into account real-time or local weather conditions.

The Snow Day Predictor uses data such as average snowfall, temperature, and historical snow day data to make its predictions. It can provide a general idea of the likelihood of a snow day occurring in a particular area, but it should not be relied on as the only source of information.
