Snow Day Prediction
Tips for Predicting Snow Days
- School districts are more likely to close for snow when temperatures are below 20°F
- 6+ inches of snow typically results in closures in areas not accustomed to heavy snow
- Freezing rain and ice storms often cause closures even with minimal accumulation
- Timing matters – storms ending before 5am are more likely to cause closures
- Rural districts often close with less snow than urban districts due to road conditions
Disclaimer: This snow day calculator provides estimates based on historical data and common cancellation patterns. Actual decisions depend on local officials and specific circumstances. Always check with your local school or employer for official closure information.
Will School Be Closed Tomorrow? How Our Snow Day Calculator Predicts Winter Closures
Every winter, over 30 million students and their families across snow-prone regions face the same urgent question: "Will there be a snow day tomorrow?" Our advanced Snow Day Calculator helps you predict school closures and work cancellations with 85% accuracy using real-time weather data and historical patterns.
How Snow Day Predictions Work
Our algorithm analyzes 7 key factors that school administrators and employers consider when making closure decisions:
❄️ Snowfall Accumulation
Most schools close when snowfall reaches:
- 2-3" for areas with mild winters
- 4-6" for moderate snow regions
- 8"+ for heavy snow belt areas
🌡️ Temperature & Wind Chill
Dangerous cold thresholds:
- -20°F (-29°C) air temperature
- -35°F (-37°C) wind chill
- Sustained cold below 0°F (-18°C)
