Forecast models from ECMWF, GFS, and national agencies indicate a highest temperature in Milan on August 21 most likely between 23–25 °C, with ensembles showing a narrow spread around 24 °C amid thundery showers and increased cloud cover that limit daytime heating. This aligns with the closely matched market-implied odds favoring 23 °C and 24 °C, reflecting recent model runs that have trended slightly cooler than seasonal averages of 26–28 °C. Key variables include steering patterns and moisture from Atlantic or Mediterranean flows, which could either suppress or briefly enhance peaks depending on timing of convection. Updated high-resolution guidance over the next 24–48 hours will refine these probabilities ahead of resolution.
