Trader consensus on Polymarket reflects the latest ensemble forecasts from ECMWF and Italian meteorological services, pricing a high of 15°C at 30% implied probability amid tight clustering around 14–16°C due to a persistent cool air mass over northern Italy. A late-April cold front ushered northerly winds and showers, suppressing temperatures well below the May climatological average of 22°C; recent model runs show daytime highs varying by 1–2°C based on cloud cover evolution and boundary layer mixing. Official guidance indicates light rain possible on May 15, potentially capping peaks at 14°C, while partial clearing could push toward 16°C. New 12Z ECMWF and GFS updates expected today may refine this uncertainty before resolution via Milan Linate Airport observations.
