Latest Météo-France forecasts and ECMWF ensemble model runs position a high of 11°C as the market-implied frontrunner at 40.5% for Paris on March 28, reflecting a consensus on persistent cloud cover and scattered showers suppressing daytime heating amid a weak Atlantic low-pressure influence. Updated GFS and UKMO outputs from the past 24 hours show minimal divergence, with ensemble means clustering around 10–12°C, down slightly from earlier warmer outlooks due to increased northerly flow and soil moisture from recent rains. Historical late-March averages hover near 12°C, but current conditions favor the cooler cluster; traders await hourly observations from official stations like Roissy for final resolution, with model refreshes overnight potentially refining the 10–12°C range amid typical spring forecast uncertainty.
