Forecast models from sources including Open-Meteo and GFS consensus currently indicate a Saturday overnight low near 13°C in Milan, driven by clear to partly cloudy skies overnight that permit radiative cooling after daytime highs around 21°C, light variable winds under 5 km/h, and typical autumn Po Valley conditions favoring modest temperature drops without strong advection. This aligns with the market-implied 45.5% on 13°C as the leading outcome, while the 39% on 17°C or higher reflects residual uncertainty from potential model spreads or slight warming if cloud cover increases. Historical October baselines show average lows near 10–12°C, placing the current setup slightly above climatology amid a stable high-pressure pattern. Updated National Meteorological Service guidance and evening model runs expected tonight will refine resolution criteria for the exact minimum.
