How the Snow Day Calculator Works

Our proprietary algorithm evaluates five critical factors:

Snowfall Amount - Measures predicted accumulation. Schools typically close when 6+ inches expected overnight.

Temperature Analysis - Examines low temperatures and wind chill. Extreme cold (-10°F/-23°C) often triggers closures.

Wind Speed Impact - Strong winds (25+ mph) reduce visibility and create dangerous wind chills.

Timing Factor - Snow during peak commute hours (6-9 AM) significantly increases closure likelihood.
