Disclaimer
Last Updated: September 3, 2026
The information and predictions provided by Snow-Calculator.com are intended for informational and general planning purposes only.
By using this website, you acknowledge and agree to the following limitations.
Snow Day Predictions Are Estimates
The Snow Day Calculator and Snow Day Predictor generate estimated probabilities based on available weather forecast data and additional factors that can influence school closures.
A result such as 70%, 80%, or 90% does not mean that a school will definitely close.
School closure decisions can depend on circumstances that a general online calculator cannot fully observe, including:
- local road conditions;
- school-bus routes;
- ice accumulation;
- timing of snowfall;
- power outages;
- staffing availability;
- building conditions;
- local transportation policies;
- individual school-board or district policies; and
- decisions made by local authorities.
Predictions should therefore be treated as estimates rather than guarantees.
Weather Forecasts Can Change
Weather forecasts are inherently uncertain and can change as new observations and forecast-model data become available.
Snow totals, storm tracks, temperature, freezing rain, wind, and precipitation timing can change significantly before a storm reaches a particular location.
A prediction generated at one time may therefore differ from a prediction generated later.
Not an Official School Closure Source
Snow-Calculator.com does not make official school closure, delay, early-dismissal, transportation, or bus-cancellation decisions.
Always verify school-related decisions through an official source such as:
- your school;
- school district;
- school board;
- official school website;
- school notification system; or
- local education authority.
Do not rely solely on Snow-Calculator.com when deciding whether to attend school, travel, or change transportation arrangements.
Not an Official Weather Service
Snow-Calculator.com is an independent website.
It is not affiliated with, operated by, endorsed by, or officially connected to any school district, school board, NOAA, the National Weather Service, Environment and Climate Change Canada, Open-Meteo, or any local, state, provincial, federal, or national government agency.
Weather forecast information used by the calculator may be obtained through third-party weather-data services.
For official weather watches, warnings, emergencies, and safety information, consult the appropriate government weather service or local authority.
Not Safety or Emergency Advice
Information on Snow-Calculator.com should not be used as a substitute for professional weather guidance, emergency instructions, transportation advice, or official safety recommendations.
Severe winter weather can create dangerous conditions even when schools remain open.
Always follow official warnings and use your own judgment when deciding whether travel conditions are safe.
If an emergency exists, contact the appropriate emergency services or local authorities.
Calculator Limitations
The Snow Day Calculator uses weather-related information and other factors to estimate school-closure probability.
It cannot know every condition affecting a particular school or community.
For example, it may not have real-time knowledge of:
- untreated local roads;
- individual bus routes;
- mechanical problems;
- localized power failures;
- staffing shortages;
- emergency declarations;
- school-specific building problems; or
- last-minute administrative decisions.
For these reasons, two nearby schools can sometimes make different decisions despite experiencing similar weather.
No Accuracy Guarantee
We work to make Snow-Calculator.com useful, transparent, and technically reliable, but we do not guarantee that:
- every forecast is correct;
- every prediction matches the eventual school decision;
- weather data is always complete or current;
- the website will always be available;
- calculations will always be error-free; or
- third-party data providers will always operate without interruption.
Past prediction performance does not guarantee future results.
Third-Party Information and Links
Snow-Calculator.com may use or link to information provided by third parties.
We do not control the accuracy, availability, policies, or content of independent third-party services or websites.
A link to another website does not necessarily mean that Snow-Calculator.com endorses that website or all information it provides.
Educational and Informational Content
Articles and guides published on Snow-Calculator.com are intended to explain topics such as:
- snow-day probability;
- weather forecasting;
- school-closure factors;
- snowfall uncertainty;
- ice and wind impacts; and
- how the calculator works.
This content is provided for general educational and informational purposes and should not be interpreted as professional meteorological, legal, educational, transportation, or safety advice.
Limitation of Liability
To the fullest extent permitted by applicable law, Snow-Calculator.com and its owner will not be responsible for losses, damages, missed school, transportation problems, travel decisions, injuries, costs, or other consequences resulting from reliance on a prediction or information provided through this website.
Users are responsible for verifying important information through appropriate official sources.
Use at Your Own Discretion
Snow-Calculator.com is designed to help users understand weather-related school-closure probability, not to replace official decisions.
Use the calculator as one source of information and context.
For actual school closures, delays, transportation changes, weather warnings, or safety decisions, always rely on the appropriate official source.
