Weather-based planning signals for winter school mornings.
Mon, Oct 12
Why this score?
Snow is forecast overnight, with little or none shown in the morning window. Overnight precipitation overlaps freezing hours; this is a risk clue, not confirmed ice.
Forecast fetched 2026-10-11 22:13 UTC.
Weather inputs & calculation
Rules replay: 78/100 using the other state group. Overnight snow 3.77 in.; 6 AM–noon snow 0.00 in.; combined scoring-window snow 3.77 in. Overnight precipitation 0.54 in. and 11 hours at/below 32°F (an ice-risk proxy, not observed ice). Lowest overnight/morning temperature 29.1°F; peak window gust 9.2 mph; previous calendar-day snow 4.88 in. No low-snow/precipitation ceiling applies. Final score is rounded and limited to 0–100. Displayed new snow may be capped by the daily total; scoring uses the full window total. Weather fetched 2026-10-11 22:13 UTC. Not a measured closure probability; official district alerts decide school status.

Winter Forecast Overview
Saved outlook updated .
Each city shows its highest weekday planning score in the saved outlook—not today’s snow or an official closure. Scores are planning signals, not measured closure probabilities.
What Snow Day Alerts does
Enter a ZIP code to see an estimate of snow-day disruption risk for the next five weekdays. The percentage is a planning signal based on forecast conditions that often lead to closures — especially overnight snow/ice and morning-commute conditions.
Using your forecast: timing, sources & limitations
How to interpret the percent
70% doesn’t mean “guaranteed closed.” It is a rules-based planning signal, not a measured probability for your district. Districts still vary based on plows, buses, staffing, and local road conditions.
- When to check: the evening before and before leaving, following your district’s notification schedule.
- Not official: always rely on your district’s alerts for final decisions.
- More detail: see How It Works and FAQ.
What we look at (high level)
- Overnight snow & ice: accumulation and freezing conditions before buses roll.
- Timing: previous-day 6 PM–6 AM and target-day 6 AM–noon, in the forecast location’s time zone.
- Wind & cold: strong gusts and dangerous cold can push delays/closures.
Data sources & limitations
- Weather data: Open-Meteo (CC BY 4.0), used to calculate our own planning signals.
- ZIP lookup: Open-Meteo geocoding, with OpenStreetMap contributors via Nominatim as a fallback and for optional device-location lookup.
- Forecasts can shift quickly; local roads, staffing, and policies can override weather.
