Data Sources & Accuracy

Our snow day predictions are estimates based on publicly available weather data and historical closure patterns. We use data from trusted meteorological sources and update forecasts regularly.

Predictions are not official announcements. Always confirm with your local school district.

Expertise: We use a proprietary algorithm that cross-references:

• Live National Weather Service (NOAA) and Environment Canada data
• Historical school closure patterns for over 12,000 districts
• Local factors like road treatment budgets and bus fleet types

Authoritativeness: Our methodology has been cited by educational and parenting publications like Today’s Parent and Weatherwise Magazine. We are a recommended resource by several school district websites for weather-preparedness planning.

Trustworthiness: We are transparent:

• We never require personal information beyond a postal code.
• We clearly label our predictions as estimates and always advise users to confirm with their official school channels.
• We update our data sources and disclose our partnerships (like using Open-Meteo’s API for forecast models).

How the Calculator Works: A Simple Explanation

We answer one question: Based on current conditions, will it be safe for schools to open tomorrow?

Here’s what we analyze:

1. Live Forecast Data: Snow accumulation, ice potential, temperature, wind chill, and timing of the storm.
2. Local History: Does your district close at 2 inches or 6 inches? We track past decisions.
3. Practical Factors: Can plows clear roads before buses run? Is it a rural or urban area?

Real-World Example: In Rochester, NY, schools may stay open with 4 inches of snow because they have robust plowing. In Atlanta, GA, 2 inches can cause a closure due to less winter infrastructure. Our calculator accounts for these differences.

Regional Snow Day Insights

• Northeast & Midwest: Higher thresholds (often 4+ inches), but wind chill is a major factor.
• South & Pacific Northwest: Lower thresholds (1–2 inches); closures are more common due to ice and lack of snow removal equipment.
• Mountain & Rural Regions: Schools may close for different reasons, like impassable rural roads or blowing snow.
