Predict snow day likelihood based on snowfall, temperature, wind, and region type.
A snow day predictor estimates the likelihood of school closings based on forecasted snowfall, temperature, wind speed, day of week, and region type using a weighted scoring system.
Good chance of a snow day. Keep an eye on announcements.
| Score | Likelihood | Meaning |
|---|---|---|
| 80–100 | Very Likely | Heavy snow, extreme cold, or high winds |
| 60–79 | Likely | Significant snowfall with cold temps |
| 40–59 | Possible | Moderate snow, could go either way |
| 20–39 | Unlikely | Light snow or mild conditions |
| 0–19 | Very Unlikely | Minimal snow or warm temps |
Formula
Score = Snowfall (0–40) + Temp (0–20) + Wind (0–15) + Day (0–15) + Region (0–10)Snowfall = 0–40 points based on inches of forecasted snow
Temperature = 0–20 points based on how far below freezing
Wind = 0–15 points for blowing/drifting snow potential
Day = 15 points if it's a weekday (school day)
Region = 0–10 points: rural > suburban > urban
Worked Example
4 in snow, 25°F, 15 mph wind, Tuesday, suburban
Did you know? The average US school district calls about 4–5 snow days per year, though some northern districts in states like Minnesota and Michigan may use up to 10 (source: Education Week).
