Time series, baselines, and the craft of predicting what comes next.
WeatherNext 3 skips the traditional data-assimilation step and forecasts straight from raw satellite observations, updating every hour instead of every six — a genuine architecture change with commercial reach far beyond meteorology.

Prediction is turning into a commodity. The value is migrating to everything around it — calibration, execution, reusable representations, and the decision a forecast is actually meant to serve.

A retailer may need a billion product-by-store forecasts a week. This method predicts only the smooth 0.3% of them, then splits the rest with loaded dice so everything adds up.

A line of algebra can match forecasting architectures thousands of times its size — if you stop scaling the model and start tuning the preprocessing nobody bothers to touch.

A popular way of training trajectory predictors quietly corrupts the probabilities a self-driving planner relies on. The fix needs no retraining — just a clearer view of what went wrong.
