How Snow Day Calculations Work

Our snow day forecast calculator uses multiple factors to determine the likelihood of closures. Here’s how each factor influences the calculation:

Temperature

Colder temperatures increase snow accumulation and reduce melting. Below 20°F significantly increases snow day probability.

Snowfall Amount

More snowfall means higher probability. Even 1-2 inches can cause delays, while 6+ inches often results in closures.

Wind Speed

High winds create dangerous wind chills and drifting snow, making travel hazardous even with moderate snowfall.

Precipitation Type

Freezing rain creates ice hazards. Sleet reduces visibility. Different types affect road conditions differently.

Timing

Storms overnight give crews time to clear roads. Morning storms during commute hours increase closure likelihood.

Region Type

Urban areas clear roads faster. Rural and mountain regions may close with less snow due to limited resources.

Snow Day Thresholds by Region (USA & International)

Region Type Delay Threshold Closure Threshold Notes
Northeastern US 2-3 inches 6+ inches Well-equipped for snow but cautious with timing
Southern US 1 inch 2+ inches Limited snow removal equipment
Midwestern US 3-4 inches 8+ inches Experienced with snow but cautious with wind chill
Western US/Mountain 6+ inches 12+ inches Well-equipped but concerned about avalanche risk
Canada/Scandinavia 4-5 inches 10+ inches Excellent infrastructure but cautious with extreme cold
UK/Western Europe 1-2 inches 4+ inches Limited experience with heavy snow
