Trader consensus on Polymarket tilts toward 17°C (28.5%) and 18°C (21.5%) as the highest temperature at Amsterdam Airport Schiphol on May 3, reflecting KNMI's latest short-range guidance projecting a maximum near 21°C amid moderate showers and 80% precipitation chance, interspersed with sun. However, ECMWF and GFS ensemble means introduce uncertainty through variable cloud cover and southerly winds at force 3, potentially reducing insolation and capping peaks 2-4°C below deterministic runs—especially if Atlantic moisture lingers from the weekend transition. Historical early May averages hover at 15-16°C, but recent high-pressure warmth has set a warmer baseline; new 12Z model updates today and tomorrow's observations will clarify if partial clearing favors 18°C over 17°C.
