Recent numerical weather prediction runs from models including ECMWF and GFS indicate a peak temperature near 29–31 °C in Milan on September 2 under stable high-pressure conditions, light easterly flow, and partly cloudy skies that limit strong diurnal heating while allowing modest boundary-layer warming. Ensemble spreads remain modest, with most members clustering in this narrow range consistent with late-summer climatology for the Po Valley, where September daily maxima average around 27–28 °C. Slight model-to-model differences in cloud cover and mixing depth introduce the residual probability mass at 32 °C or higher, yet no major pattern shift has emerged in the latest 24–48-hour updates. Final surface observations tomorrow will resolve the exact maximum, with traders weighting the tight consensus heavily.
