Latest ensemble forecasts from Météo-France and ECMWF models peg Paris's highest temperature on March 28 around 10-11°C, driving trader consensus toward those outcomes amid tight competition. A persistent northerly flow ushering cooler maritime air has suppressed daytime heating, with extensive cloud cover—evident in recent satellite imagery and model soundings—limiting solar insolation and capping boundary layer temperatures. GFS runs show minor divergence, hinting at possible afternoon clearing that could nudge highs to 12°C, while historical late-March averages hover near 11°C under similar synoptic patterns. Inherent forecast uncertainty stems from cloud evolution and exact wind shear; check Météo-France's 12Z update tomorrow for refined hourly guidance as resolution nears.
