Short-term weather models from Météo-France and ECMWF drive trader consensus toward a Paris high of 15°C (46% implied probability), with ensembles clustering peaks at 14-16°C amid a high-pressure ridge fostering mild spring conditions. Recent forecast updates, incorporating southerly flows and minimal cloud cover, shifted odds upward from cooler 13-14°C outlooks earlier this week, while historical late-March averages (~13°C) and low volatility cap extremes below 1% for 18°C+. Official measurements at Paris-Montsouris station will resolve the diurnal maximum, but model convergence tempers divergence risks as the date nears.
