How Our Snow Day Prediction Algorithm Works
Our proprietary algorithm integrates real-time NOAA weather API data with machine learning models trained on historical school closure patterns. Here's what we analyze:
Snowfall Analysis
Total accumulation, snowfall rate per hour, and timing relative to school hours.
Ice & Freezing Rain
Ice accumulation probability, freezing rain advisories, and road treatment status.
Wind Chill & Temperature
Extreme cold warnings, wind chill advisories, and dangerous temperature thresholds.
Historical Patterns
District-specific closing thresholds based on 10+ years of historical data.
Data sources: National Oceanic and Atmospheric Administration (NOAA), National Weather Service (NWS) regional offices, and Open-Meteo weather API. Updated every 15 minutes during active winter weather events.
Snow Day Predictions by State
Get localized predictions with state-specific weather data and school closing patterns.
Frequently Asked Questions about Snow Day Predictions
It depends on when it falls. 3 inches at 5 AM is more dangerous than 5 inches at 5 PM. Our algorithm weights timing heavily. Early morning snowfall that affects the morning commute has a much higher impact on school closures than afternoon snow. Additionally, whether roads have been treated and local district policies play a significant role.
We don't just look at snow depth. We track icing updates and wind chill advisories live to give you the most precise percentage available in 2025. Our AI algorithm analyzes multiple weather factors including snowfall amount, ice conditions, temperature, wind speed, and storm timing. While no predictor can guarantee 100% accuracy (school districts make their own decisions), our model is designed to give you the best possible estimate based on current weather data.
