ECMWF ensemble means project a 19°C high for Paris on May 6, with GFS operational runs aligning at 18°C. A persistent high-pressure ridge over Western Europe is favoring warm thermal advection from the SW, pushing surface temperatures above the 17°C threshold. Diurnal heating under mostly clear skies will ensure the daily max clears this value comfortably. Betting on the positive thermal anomaly. 90% YES — invalid if a significant cold frontal passage stalls over Ile-de-France.
