Trader consensus on Polymarket overwhelmingly favors highs of 21°C or higher in Milan today at 94.5% implied probability, driven by the latest guidance from Italy's official Servizio Meteorologico dell'Aeronautica Militare (MeteoAM) projecting around 20-21°C alongside upside from ECMWF and other model ensembles showing peaks to 22°C under a persistent high-pressure ridge over northern Italy. Morning observations at Milan Malpensa Airport indicate starting temperatures near 14°C with ample solar insolation and light winds enabling strong diurnal heating typical of spring anticyclonic conditions. This aligns with recent days' mild pattern, exceeding April climatological averages of 17°C. Realistic challenges include late-afternoon cloud buildup or isolated thunderstorms reducing peak temperatures to exactly 20°C, though model agreement remains robust with hourly updates through evening.
