Trader consensus on Polymarket tilts toward 11°C (27% implied probability) as Paris's highest temperature on March 27, closely trailed by 12°C (24.5%), reflecting the latest ECMWF and GFS ensemble forecasts projecting peaks of 10-12°C under a persistent northerly flow and mid-level clouds. Météo-France's AROME model corroborates this, showing midday maxima near 11°C with light showers suppressing warmer outliers. Key differentiators include jet stream undulations nudging cooler maritime air southward, reducing 13°C+ odds to 23% combined, while soil moisture from recent rains limits diurnal heating. Historical March 27 averages hit 12°C, but current upper-air patterns favor the lower end of that range amid model convergence.
