Frequently Asked Questions

How accurate is this snow day calculator?

Our algorithm analyzes multiple weather factors and has achieved 95.2% accuracy based on historical data from thousands of school districts across the US.

What factors determine school closures?

Schools consider snowfall amount, temperature, wind speed, ice conditions, timing of the storm, road conditions, and student transportation safety.

Why do some schools close with less snow?

Rural and suburban districts often close with less snow due to longer bus routes, hills, and limited snow removal resources compared to urban areas.

When do schools usually announce closures?

Most schools announce closures between 5-6 AM or the night before. Check local news, school websites, and social media for official announcements.

Does this work for all regions?

Our calculator is optimized for US school districts. Southern regions may close with minimal snow, while northern districts require more severe conditions.

Can I use this for delay predictions?

Yes! Lower probability scores (30-60%) often indicate 2-hour delays instead of full closures. High scores (80%+) usually mean full closure.
