Latest forecast ensembles from global models like ECMWF and GFS, corroborated by China Meteorological Administration guidance, drive trader consensus toward an 18°C high in Shanghai on March 29 (31% implied probability), reflecting mild spring conditions with southerly winds transporting warmer air masses amid neutral ENSO patterns. Recent observations show daily highs stabilizing in the 15–19°C range over the past week, following a brief cool spell from northerly outflows, boosting confidence in mid-teens outcomes while capping extremes. High uncertainty stems from model spread on cloud cover and frontal timing—clear skies could push toward 20°C+ (12.5–7%), while overcast conditions or stalled systems favor 17°C or below (16.5–6.5%). Traders eye tomorrow's updated runs for shifts before resolution.
