Current forecasts from European models indicate Milan’s overnight minimum on September 2 will likely settle between 18–21 °C, with the tight clustering of market-implied odds around 15–23 °C reflecting modest uncertainty in boundary-layer cooling. Clear to partly cloudy skies and light northeasterly winds under high pressure favor efficient radiative heat loss after sunset, while any increase in low-level moisture or lingering cloud could limit the drop by 1–2 °C. These conditions align closely with early-September climatology for the Po Valley, where average lows hover near 18 °C. Updated model runs and the evening sounding from Milano Linate will provide the final data points before the market resolves.
