Everything you need to know about our snow day predictions
Our predictor achieves approximately 85-95% accuracy depending on the region and timing. Predictions made the evening before are most accurate as weather models have the freshest data. We continuously improve our algorithm based on actual school closing outcomes.
For the most accurate prediction, check between 7-10 PM the evening before. This is when weather models have the best data for overnight snowfall. We also update predictions at 5 AM for early morning checks.
We cover all public school districts in the United States and most Canadian provinces. Private schools and universities may have different closing thresholds, but our predictions still provide a strong baseline estimate for any location.
We aggregate data from the National Weather Service (NWS), Environment Canada, NOAA weather models, local weather stations, and historical school district closing records. Our AI model combines all of these inputs to generate each prediction.
