Current numerical weather prediction models, including recent ECMWF and GFS runs, indicate a warm air mass advecting over southern Germany, supporting a June 23 maximum near 32 °C in Munich with light rain or showers possible midday. This consensus underpins the market’s tight clustering around 31–33 °C, where small differences in cloud timing, boundary-layer mixing, and precipitation onset create the observed spread between leading outcomes. Ensemble variability remains modest two days out, yet traders weigh the risk that earlier or heavier showers could cap the peak at 31 °C versus clearer intervals allowing 33 °C, with official DWD observations on the day serving as the resolution source.
