How the Snow Day Calculator Works
This calculator estimates the probability of school cancellation based on several weather factors. It's a fun prediction tool — not a replacement for official school closure announcements.
Factors That Affect Snow Days
- Snowfall amount: More snow = higher chance. Even 2-3 inches can close schools in areas that rarely get snow.
- Temperature: Extreme cold can cause closures even without snow due to dangerous wind chills.
- Ice: Freezing rain and ice storms are more dangerous than snow and often lead to closures.
- Timing: Overnight storms that end by morning give plows time to clear roads; early morning storms are worse.
- Region: Southern states close with less snow since they have less snow removal infrastructure.
