💡 How Snow Day Prediction Works

Predicting a snow day involves much more than just looking at total inches of snow. School superintendents make cancellation decisions based on road safety, bus routing, and sidewalk conditions for walking students. For example, a heavy snowfall at 3:00 AM might result in a closure because crews cannot clear the roads in time, while the same amount falling at 8:00 PM the night before gives plows enough time to prepare. Our algorithm mimics this administrative logic by combining accumulation totals with temperature thresholds and ice risks to calculate a highly realistic probability.

💡 Administrative Disclaimer

Keep in mind that every school district has its own unique policies regarding weather closures. While our calculator provides a highly accurate estimate based on meteorological data, the final decision always rests with your local school superintendent. Always check your local news or school website for official announcements!
