How the Snow Day Calculator Works
Our snow day calculator uses a sophisticated algorithm that weighs multiple weather factors to generate accurate snow day predictions:
- Snow accumulation (65% weight): Higher totals raise the chance of school closures
- Ice risk (20% weight): Freezing rain between 28-33°F is the most dangerous condition
- Temperature (10% weight): Extremely cold temperatures affect road conditions
- Wind gusts (10% weight): High winds create dangerous driving conditions and reduce visibility
- Timing (8% bonus): Overnight snow that hits the morning commute is more disruptive
- School type: Different institutions have different closure thresholds
The calculator provides an estimated probability based on historical school closure patterns and weather data analysis.
Snow Day Probability Scale
0% - No chance due to low precipitation
1-54% - Little to no chance, but possible
55-74% - Delay likely (2-hour delay expected)
75-86% - Possibility of no school
87-100% - No school or early dismissal likely
