Snow Day Predictor is designed to help Canadian families, students, and teachers better understand how winter weather might affect school operations. This page explains what the tool can and cannot do, so you always know its limitations.
My commitment is to be open, honest, and clear, just as the rest of the website is.
1. General Information Only
Snow Day Predictor provides general, informational guidance, not official forecasts.
The tool is designed to:
- Offer an early indication of snow-day likelihood
- Help families plan ahead
- Translate complex weather data into a simple percentage
- Highlight conditions that commonly lead to bus cancellations or closures
However, the snow-day estimates are not official announcements.
They should never be used as the final basis for deciding whether to attend school, travel, or keep children home.
2. Not a Substitute for School Board or Transportation Decisions
Every school board and bus provider uses its own criteria and on-the-ground assessments.
This means:
- Closure decisions can differ from the prediction
- Districts may close even with a low percentage
- Districts may remain open even when the model shows a high probability
- Conditions can change rapidly in ways that forecasting tools cannot fully capture
Always follow official updates from your school board, bus provider, or local authorities.
They remain the definitive source of information.
3. Forecasting Limitations
While Snow Day Predictor relies on trusted and reputable weather services, all forecasts carry inherent uncertainties. The accuracy of the prediction depends on:
- Sudden changes in storm track
- Local variations within a region
- Microclimates and rural/urban differences
- Shifts in temperature, timing, or precipitation type
- Weather data availability and update frequency
The prediction percentage is an estimate, not a guarantee.
4. No Liability for Decisions Based on Predictions
By using this website, you agree that Snow Day Predictor, Sarah Thompson (creator and owner), and any contributors or developers cannot be held responsible for:
- Missed school or work
- Travel decisions
- Childcare planning
- Inconveniences or disruptions
- Losses of any kind resulting from reliance on the prediction
You are responsible for making your own decisions based on official sources.
5. Accuracy and Updates
The tool aims to be as accurate and timely as possible, and I continually refine it as winter patterns evolve. However:
- Forecasts are not guaranteed
- Information may be updated or corrected without notice
- The website may temporarily experience delays or outages
Snow Day Predictor is provided “as is” without warranties of any kind.
6. External Links
The website may include links to external resources, weather data providers, or relevant educational materials. These are for convenience only.
Snow Day Predictor does not:
- Control third-party content
- Guarantee its accuracy
- Endorse external websites or services
Your use of external resources is at your own discretion.
7. Postal Code and Data Use
The tool requires a Canadian postal code solely to:
- Identify a general region
- Retrieve a local forecast
- Produce an estimated snow-day probability
Postal codes are never used to identify individuals.

8. When in Doubt, Check Official Sources
If you’re uncertain about conditions or concerned about safety, always refer to:
- Your school board’s official website
- Bus transportation providers
- Local news and weather services
- Environment Canada warnings
These are the authoritative channels for closures and cancellations.

In Summary
Snow Day Predictor is here to help Canadians prepare for winter, not to replace official weather forecasts or announcements.
The predictions offer guidance, not guarantees, and should be used responsibly alongside trusted local sources.
Thank you for using the Snow Day Predictor and for making this community a thoughtful, informed part of winter planning.
