Snow day questions, answered
How accurate is the snow day predictor?
It’s a transparent probability estimate, not an official announcement. The model weighs forecast snowfall, ice, overnight timing, wind, existing snow, and extreme cold, adjusted for your region and district type. Real closures also depend on local judgment calls, so treat the percentage as a well-informed guess — and always confirm with your district.
What counts as a snow day vs. a 2-hour delay?
A “snow day” is a full school closure. A “2-hour delay” is a late start, which districts use for marginal storms — enough to plow and de-ice but not enough to cancel. We show both, because the delay odds peak exactly when a storm is borderline.
Why is the chance ~0% on weekends?
There’s no school to cancel, so Saturdays and Sundays are forced to zero. The 5-day outlook still shows them for context.
