How the odds are built

P(snow day) ≈ f(snow, cold, wind, forecast, district)

Each input earns points (heavy snow scores high, mild flurries score low), scaled against your area’s tolerance, then shifted by how trigger-happy the district is. The result is clamped between 2% and 98% — there is always a little uncertainty. It’s a heuristic for fun, not a real forecast.

🌬 Live gauge

A half-moon probability meter sweeps from “no chance” to “wake up late.”

🌡 Local tolerance

Buffalo vs. Atlanta: the same forecast scores very differently.

😅 Honest verdict

Readable one-liners from “bring your books” to “sleep in.”

❓ Transparent scores

See the sub-scores so the number doesn’t feel like magic.
