Latest weather models, including ECMWF and GFS ensembles, drive trader consensus toward a Shanghai high of 18-19°C on March 22, with minimal spread reflecting high confidence in mild southerly winds advecting warmer air masses amid low cloud cover. These outcomes edge out 17°C and 20°C due to historical March 22 averages around 15°C but recent anomalous warmth—Shanghai's early spring has seen +3-5°C deviations from norms, per China Meteorological Administration data. Differentiating factors include afternoon insolation potential boosting peaks above 19°C if clear skies persist, versus marine layer cooling risks holding at 17-18°C; traders await 00Z model runs for resolution clarity.
