Latest China Meteorological Administration forecasts and international models like ECMWF and GFS project Chengdu's highest temperature on May 4 clustering around 27-29°C, driving the tight trader consensus with 36% implied probabilities for 26°C and 27°C amid a rebound from May 1's observed 20°C cool spell under cloudy conditions. This bunching reflects uncertainty in diurnal boundary layer heating within the Sichuan Basin's hazy, light-wind environment—persistent high pressure and urban heat island effects favor 28-30°C peaks, while potential afternoon cumulus clouds could suppress to 26-27°C. Early-May climatology averages 26°C highs, with resolution based on official Chengdu Shuangliu Airport observations; watch tomorrow's updated model ensembles for shifts.
