Trader consensus clusters tightly around 19-22°C for Chongqing's March 27 high, driven by global model ensembles like ECMWF and GFS projecting peaks in this narrow band amid springtime variability. Recent observations show preceding days topping 19-20°C under partly cloudy skies, with historical March averages at 18.5°C providing baseline context. Differentiating factors include the timing of a weak shortwave trough—potentially capping highs at 19-20°C via increased cloudiness and northerlies, or allowing 21-22°C under clearer conditions and urban heat island amplification. Diurnal ranges of 10-12°C further heighten uncertainty, with China Meteorological Administration's next update pivotal for resolution.
