Frequently Asked Questions

Everything you need to know about snow day predictions and how Snow Day Signal works.

How does Snow Day Signal predict school closures? +

Our algorithm analyzes multiple data points from the National Weather Service including snowfall amounts, ice accumulation, wind chill, and temperature forecasts. We then factor in your region's "snow preparedness" level-areas like Minnesota handle 6 inches of snow differently than Georgia. By combining real-time weather data with historical closure patterns, we calculate the probability of school closures or delays for your specific location.

How accurate are snow day predictions? +

Snow Day Signal uses the same weather data that school administrators rely on-National Weather Service forecasts, winter storm warnings, and local conditions. Our predictions improve as the forecast date approaches since weather data becomes more reliable. We continuously refine our algorithm based on actual closure patterns. Keep in mind that final closure decisions are always made by local school administrators who may consider factors beyond weather.

What time should I check for snow day predictions? +

For the most accurate prediction, check Snow Day Signal the evening before (around 8-10 PM) and again early in the morning (5-6 AM). Weather forecasts become more accurate as the event approaches, and many schools make their final closure decisions between 5-6 AM. Our data updates hourly, so you'll always see the latest forecast information available.

Does Snow Day Signal work for all schools? +

Snow Day Signal provides predictions for public and private K-12 schools across all 50 U.S. states. Our predictions are based on geographic location and local weather conditions. While individual schools may have different closure thresholds, our algorithm is calibrated to predict the most likely outcome for schools in your area. Colleges and universities often have different closure policies and may remain open when K-12 schools close.

What's the difference between a snow day and a delay? +

A snow day means school is completely closed for the day-no classes, no activities. A delay (typically 1-2 hours) means school starts later than normal to give road crews time to clear streets and allow safer travel conditions. Schools often opt for delays when snow is expected to taper off by mid-morning. Snow Day Signal shows both the probability of a full closure and the chance of a delay so you can plan accordingly.

Is Snow Day Signal free to use? +

Yes! Snow Day Signal is completely free with no account required. Just enter your ZIP code or use your device's location to get an instant prediction. We believe every family deserves access to accurate weather and closure information without barriers. There are no premium tiers, no paywalls, and no hidden fees.
