Snow Day Heuristic Calculator
Weather
This tool does not fetch weather data, road conditions or school notices. It adds fixed points to the values and context you enter, then clamps the total to 0–100. Treat that number as a transparent heuristic score, never as a scientific probability, forecast or school-closure decision.
Use the manual score carefully
-
1
Bring your own forecast
Enter inches, degrees Fahrenheit and mph from a source you trust.
-
2
Describe local context
Choose broad area, timing, district tendency and any signal you have already verified.
-
3
Check official sources
Use the score only as a checklist, then follow your district, road authority and emergency alerts.
What the number means
The code assigns fixed points to ranges of snowfall, ice, temperature and wind, then adds hand-set adjustments for area type, timing, assumed district tendency and selected local signals. These weights were not trained or validated against closure outcomes. A score of 70/100 does not mean a 70% probability.
No location, forecast time, precipitation type, road temperature, plowing capacity, terrain, bus routes, staffing, power status or district policy is measured. Selecting “district already announced” forces 100/100, but the tool cannot verify that claim.
Use the National Weather Service forecast and winter alerts in the US, or the official meteorological and road services for your country. Only the school authority can announce a closure, delay or remote-learning plan. Values are sent to the server through Livewire; funnel mode also places them in the URL.
