Recent ECMWF and regional model runs point to a daily maximum near 23°C in Milan, with increased cloud cover and scattered thundery showers suppressing solar heating in the Po Valley boundary layer. Ensemble spreads reflect modest uncertainty between 22–24°C, driven by small differences in predicted convective timing, moisture advection, and local urban heat island effects that can alter peak readings by 1–2°C. These factors explain the tightly matched market-implied odds around 22–23°C, as traders weigh the balance between partial clearing allowing brief warming versus sustained instability capping temperatures below seasonal averages near 28–30°C. Official updates from Italian meteorological services will refine resolution criteria before the day ends.
