How Our Prediction Works
A multi-factor scoring model combining real-time NWS/Open-Meteo data, historical patterns, and district behavior.
Hyperlocal Data Pull
We geocode your ZIP to lat/long and pull 24-hour hourly NWS + Open-Meteo data: snowfall, ice codes, temperature, wind speed/gusts, and weather alerts.
Multi-Factor Scoring
Our algorithm applies precise weights to each factor. Snowfall over 6 inches or freezing rain triggers high point values, while timing is crucial.
AI-Refined Output
Ensemble ML regression trained on 2 years of historical closures refines the raw score. District policy (Strict/Lenient) applies a final adjustment.
Accuracy Formula
Verified Data Sources
Proven Accuracy
Backtested against thousands of historical school closures across 50+ US school districts.
