Trader sentiment clusters tightly around 20–22°C for Chengdu's March 27 high temperature, driven by ensemble weather models like ECMWF and GFS forecasting maxima in this narrow band amid transitioning spring patterns. Recent model runs show a slight warming trend from southerly winds advecting mild air masses over Sichuan Basin, tempered by lingering stratiform cloud cover and residual soil moisture from prior rains, which cap peak heating. Historical late-March norms hover near 19°C, but urban heat island effects in Chengdu add 1–2°C uplift; low odds for extremes reflect stable upper-air ridge suppressing heatwaves or cold snaps. Key differentiator: hourly solar insolation forecasts, with clearer skies favoring 22°C over cooler 20°C outcomes. Watch CMA updates for final resolution nudge.
