Trader sentiment clusters tightly around 16°C and 17°C for Paris's highest temperature on March 20, driven by the latest ECMWF and MeteoFrance ensemble forecasts projecting peaks of 15.5–17.5°C amid a mild southerly airflow. This reflects a high-pressure ridge stabilizing over Western Europe, displacing cooler Atlantic influences, with historical March 20 averages near 12°C but recent mild winters elevating baselines. Differentiating factors include model spread on afternoon cloud cover—thicker stratus could cap at 16°C, while clearer skies favor 17–18°C—and subtle jet stream shifts, per GFS updates. Low probabilities for extremes underscore ensemble consensus on moderate warmth, though diurnal timing remains key to resolution.
