Recent short-range ensemble forecasts place Milan's July 13 maximum near 32–33 °C at official stations, creating the tight 36.5 %–30 % split in market-implied odds. Clear skies and subsiding high pressure favor strong daytime insolation and limited cloud cover, while modest southeasterly flow and urban heat-island effects in the Po Valley add 1–2 °C locally. Model spread arises mainly from small differences in boundary-layer moisture and timing of any weak frontal passage, which could shave or add a degree at peak afternoon heating. Updated runs from ECMWF and GFS over the next 24 hours will likely tighten or shift the distribution ahead of market resolution.
