Latest ensemble forecasts from ECMWF and Météo-France indicate a high temperature around 10-11°C in Paris on March 28, propelled by a cool northerly airflow and persistent cloud cover, closely aligning with the top market-implied odds of 28% for 11°C and 25.5% for 10°C. These differentiate from 12°C (18%) due to model consensus on limited insolation from overcast skies and weak diurnal heating, against historical late-March averages of 12-13°C. GFS runs show slight bullish bias toward 12°C, but operational updates emphasize overnight clearing risks remaining low, with resolution hinging on 12Z model refreshes; trader caution reflects typical spring forecast uncertainty within 1-2°C spreads.
