Current numerical weather prediction models, including GFS guidance, indicate overnight lows in Milan on September 27 around 13–16°C under clear skies, light northeasterly winds, and stable high pressure favoring moderate radiative cooling. These conditions align with late-September climatology for the Po Valley, where calm nights typically produce minima several degrees below daytime highs of 24–25°C. The 50% market-implied odds on 7°C or below versus 17°C or higher reflect uncertainty in exact boundary-layer cooling rates and any last-minute shifts in wind or cloud cover, while specific bins clustered around 13–16°C capture the consensus range. Updated model runs and local observations over the next 48 hours will refine minimum thresholds ahead of resolution.
