Trader consensus on Polymarket tilts toward an 11°C high in Paris on March 28 at 22.5% implied probability, edging out 12°C and 10°C amid tight clustering, primarily driven by the latest ECMWF and GFS ensemble forecasts converging on 10-12°C under a cool northerly airflow from a lingering low-pressure system over northern Europe. Météo-France's official projection aligns at 12°C with partly cloudy conditions, matching March historical averages of 11°C while accounting for urban heat island effects. Key differentiators include ECMWF's slightly cooler bias versus GFS's warmer tilt, with 2-3°C model spread reflecting uncertainty from jet stream waviness; traders await 12Z updates for potential refinements.
