Forecast models from agencies tracking the region show Milan’s minimum temperature on September 16 likely settling near 18–19 °C, driven by increased cloud cover and scattered thunderstorms that limit overnight radiative cooling after daytime highs reach 25–27 °C. Light easterly winds and rising humidity from approaching low pressure reduce the potential for sharp drops below 17 °C, while the absence of strong cold-air advection keeps extremes above 13 °C or 23 °C improbable. Recent model runs converge on this range, with precipitation probabilities of 50–80 % overnight supporting modest cooling but not widespread clearing that could produce lower readings. Traders appear to weigh these ensemble signals against typical early-September climatology, where Milan minima average near 16 °C, creating tight implied odds across the 14–22 °C outcomes. Updated high-resolution guidance expected in the next 24–48 hours will refine the exact minimum.
