Latest ensemble forecasts from global models like ECMWF and GFS pinpoint a Shanghai high of 16°C on March 27, driving its 38% implied probability as traders price in moderating northerly winds after a cold front. Recent observations show March 26 highs near 17°C with clear skies transitioning to partly cloudy conditions, aligning with seasonal norms of 12-15°C but elevated by persistent mild air masses from the East China Sea. Lower odds for 17°C (22.5%) and 15°C (17.5%) reflect model spread amid urban heat island effects boosting nighttime mins to 10°C, while extremes like 21°C+ (1.5%) fade due to no heatwave signals in upper-air data. Key watch: afternoon humidity spikes could cap peaks.
