Memphis: the models split by day 4
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 temperature. 50 means the models disagree as much as the ensemble expects.

Hover or tap the chart to read each model at that hour. The grey band is the range the ensemble puts 80% of its members in.
Day by day
Each model's high and low for the 24 hours ending at the time shown, °C. Δ is how much that model's high moved since its previous run, twelve hours earlier.
