Snow Day Calculator

Will school be cancelled tomorrow? Get real-time predictions based on live weather data!

When we were kids, winter nights meant peeking out the window, listening to the forecast, and hoping the morning brought that magical announcement: snow day. This tool is a small nod to that feeling—now with better data.

How Our Snow Day Calculator Works

Our advanced snow day predictor uses real-time weather data from Open-Meteo combined with historical school closure patterns to calculate the probability of a snow day in your area.

Real Weather Data

We fetch live temperature, snowfall predictions, and wind speed data for your exact location to provide the most accurate forecast.

Regional Patterns

Different regions have different thresholds. Southern states close schools with less snow, while northern states need more severe conditions.

Historical Data

Our algorithm considers typical closure patterns based on decades of school closing decisions across the United States.

Smart Algorithm

We analyze temperature, snowfall amount, wind conditions, day of week, and regional factors to generate an accurate probability score.

Snow Day Thresholds by Region

🏔️ Northeast (NY, MA, PA)

Typical closure threshold: 6+ inches

Schools are well-equipped for snow. Closures usually occur only with heavy snowfall, dangerous temperatures below 10°F, or severe wind conditions.

❄️ Midwest (IL, MI, OH)

Typical closure threshold: 5+ inches

Similar to the Northeast, Midwest schools are prepared for winter weather but close with significant accumulation or dangerous wind chill.

🌵 South (TX, GA, FL)

Typical closure threshold: 2+ inches

Limited snow infrastructure means even light snow causes closures. Any accumulation or icy conditions typically result in school cancellations.

🏔️ West (WA, CO, CA)

Typical closure threshold: 4+ inches

Varies greatly by altitude and location. Mountain areas handle snow well, but urban areas close more readily.

Frequently Asked Questions

How accurate is this snow day calculator?

Our calculator provides probability estimates based on real weather data and historical patterns. While highly informative, final decisions are made by individual school districts based on local conditions.

When should I check for the best prediction?

Check the evening before (around 8-10 PM) and again early morning (5-6 AM) for the most accurate forecast as weather predictions become more precise closer to the event.

Why do southern states close schools with less snow?

Southern regions lack snow removal infrastructure (plows, salt trucks) and drivers have less experience with winter conditions. Even 1-2 inches can create dangerous situations.

Does this work for snow delays or just closures?

Scores between 50-70% often indicate possible delays rather than full closures. Check your local school district's website or news for official announcements.
