Trader consensus on Polymarket prices a 46.5% implied probability for a 21°C high temperature at Milan Malpensa Airport on May 1, closely followed by 22°C at 29.0% and 20°C at 21.5%, driven by the latest ECMWF and GFS ensemble forecasts converging on daytime peaks of 20-22°C under a persistent high-pressure ridge fostering abundant sunshine and light southerly winds. AccuWeather aligns with a 21°C (70°F) maximum amid clear skies, while historical early May data at the station shows average highs near 20°C with a typical range of 18-23°C, tempered by springtime variability from Po Valley influences. Ensemble spreads reflect inherent model uncertainty, with new observational data and hourly updates through May 1 poised to refine outcomes before official airport measurements resolve the market.
