Recent forecasts from major models indicate scattered showers and thundery activity over southern Germany on August 21, suppressing daytime heating after warmer conditions earlier in the week. This setup favors a maximum around 21–22°C in Munich, consistent with market-implied odds where those outcomes lead at 32% and 22.5%. Key differentiators among the tightly bunched probabilities include the timing and coverage of convective clouds, which reduce solar insolation, and modest variations in low-level moisture advection from the west. Ensemble spreads show limited potential for clearer skies that could push highs to 23°C or above, while stronger rain timing keeps some scenarios near 20°C. Updated runs from agencies like the DWD and ECMWF will refine these details ahead of resolution.
