How calculators analyze live weather to predict school closures.
The real factors superintendents weigh during snowstorms.
Stay safe before, during, and after winter storms.
Our calculator pulls live weather data from OpenWeatherMap with Open-Meteo fallback, including temperature, snowfall forecasts, wind speed, visibility, and precipitation. A multi-factor model analyzes these variables against common school district closure thresholds to generate a probability score with detailed explanations.
No prediction is guaranteed. School closure decisions depend on district-specific policies, local road conditions, and superintendent judgment. Use our calculator as one tool among many - always follow official district announcements.
We support any location in the United States and Canada. Enter a city name, state/province, or ZIP/postal code. You can also use GPS to detect your current location automatically.
Weather data comes from OpenWeatherMap first, with Open-Meteo as a live fallback provider. Data is updated continuously and never hardcoded or randomly generated.
