Denver: the models broadly agree this week
Four forecasts from the 16 Sep 12Z run: ECMWF's learned model (AIFS), its physics model (HRES), Google DeepMind's WeatherNext 2, and the ECMWF ensemble mean, with the ensemble's 10–90% range shaded behind them.
Driven by pressure. 50 means the models disagree as much as the ensemble expects.
