Anatomy of a forecast.
This is what one prefecture receives: layers you can pull apart and check.
Seven days, seven colors. The week reads left to right.
How sure the model is, written on the forecast itself.
Rebuilt every morning from the newest official data.
Every outlook traces back to the Japan Meteorological Agency.
Every forecast shows its work.
Arovyx supports decisions, it does not replace them. Each outlook keeps the model's reasoning open for inspection.
Prediction is not authority.
Same day, same prefecture — two documents. One states facts. One is labeled a prediction. They never merge.
