Latest short-range forecasts from ECMWF and GFS model ensembles, corroborated by China's Meteorological Administration, center on a Shanghai high of 14-16°C on March 23, driving the tight race among these outcomes with 28%, 25%, and 23% implied probabilities respectively. This consensus reflects weakening Siberian High influence and a passing upper-level trough, tempering daytime heating amid partly cloudy skies and light southerly winds, per official guidance. Differentiation hinges on 1-2°C uncertainty from microscale factors like urban heat island effects at Xujiahui station and potential low cloud persistence, against a March 23 historical average of 13.5°C; traders weigh recent model runs showing slight bullish bias toward 15°C amid spring variability.
