All major global models, particularly the ECMWF operational run and GFS ensemble mean, project robust thermal advection pushing 850 hPa temperatures well above climatological norms for Île-de-France by May 11. Persistent high-pressure ridging establishes favorable anticyclonic subsidence, clearing skies and maximizing insolation. We're observing a consistent +3 to +5°C positive temperature anomaly in the mid-troposphere, translating to surface highs confidently exceeding 20°C. Market is underpricing this synoptic setup. 90% YES — invalid if a sudden cut-off low develops west of France.
