Latest ensemble forecasts from ECMWF and GFS models drive trader consensus toward 17°C (56.5% implied probability) as Paris's highest temperature on March 21, with 16°C close behind at 32.5%, reflecting mild westerly flows ushering Atlantic warmth into Western Europe. Météo-France guidance aligns, projecting highs 4-5°C above the March 21 climatological normal of ~13°C amid a high-pressure ridge and positive North Atlantic Oscillation phase. Recent 00Z model runs reduced 18°C+ odds to 9% by tightening the temperature spread, while negligible probabilities below 15°C match the absence of cold-air outbreaks in current synoptic patterns. Traders eye afternoon soundings and 12Z updates for final conviction.
