Ensemble forecasts from Météo-France's high-resolution Arôme and Arpège models, alongside ECMWF and GFS guidance, place Paris highs around 18°C today at Charles de Gaulle Airport station, the market's resolution source, under a stabilizing high-pressure ridge fostering clear skies and efficient solar heating from morning temperatures near 14-15°C. Trader consensus reflects this at 44% implied probability for 18°C versus 35.5% for 19°C, with close positioning driven by model spread—some runs capping below 17°C due to potential afternoon cumulus development or lighter southerly winds—amid April climatological averages of 15-16°C. Key differentiators include exact timing of peak insolation and cloud onset; watch METAR updates and Météo-France hourly bulletins this afternoon for shifts ahead of evening resolution.
