Tight clustering of market-implied probabilities around 17–19°C for Chongqing's March 25 high temperature stems from consensus across ECMWF and GFS ensemble forecasts, which project mild highs amid early spring southerly flow and partial cloud cover. Recent model runs show a 1–2°C spread due to urban heat island amplification in the megacity versus cooler rural sensors, with weak ridging aloft preventing stronger warming. Differentiating factors include diurnal timing of peak insolation and potential afternoon showers capping 19°C, while historical March norms (average 16–18°C) and no anomalous fronts keep extremes like 23°C+ below 15% odds. Hourly observations from CMA stations will refine trader consensus as the date nears.
