Snow Day Calculator
Predict school closure likelihood from snowfall, temperature, and forecast inputs.
How Does the Snow Day Calculator Work?
Our snow day calculator uses a logistic regression model to estimate the probability of school closures based on weather conditions. It factors in temperature, snowfall amount, wind speed, and your school's historical flexibility with weather-related closures. The model weighs snowfall most heavily, followed by cold temperatures, school flexibility, and wind speed to produce an accurate probability percentage.
Factors That Influence Snow Days
Several factors determine whether schools close for snow. Heavy snowfall is the primary driver, as roads and sidewalks become dangerous for buses and pedestrians. Extremely cold temperatures can also trigger closures due to frostbite risk. High winds combined with snow create whiteout conditions and dangerous wind chills. Finally, each school district has its own threshold for closures — some cancel at the first sign of accumulation while others require significant snowfall before shutting down.
Tips for Preparing for a Snow Day
Even if the probability is high, it's wise to prepare for either outcome. Check your school's official communication channels the night before and early morning for closure announcements. Have your homework and materials ready in case school is open. Stock up on essentials like food, batteries, and warm clothing. If school is cancelled, use the time productively by catching up on assignments or enjoying safe outdoor activities.
