How It Works
The calculator combines two main factors to determine the likelihood of a snow day:
- Base Score: Calculated from your location and the current month
- Winter months have higher base scores
- Northern states and high-snowfall regions get higher location multipliers
- Weather Score: A secret formula that considers:
- Temperature and wind chill factors
- Current precipitation and its type
- Atmospheric conditions and cloud patterns
- Local weather patterns and historical data
- Real-time weather observations
Understanding the Results
The final percentage indicates the likelihood of a snow day:
- 0-25%: Very unlikely - normal school day expected
- 26-50%: Possible but not likely - monitor conditions
- 51-75%: Good chance - prepare for possible snow day
- 76-99%: Very likely - high probability of school closure
