ECMWF and GFS ensemble means show a persistent thermal trough driving significant warm air advection into the Sichuan basin. Current boundary layer dynamics and suppressed cloud cover from a developing high-pressure ridge indicate strong surface heating potential. While the median forecast sits at 27-28°C, a substantial 35% of ensemble members cross the 29°C isotherm, indicating a higher probability than suggested by the mean. 70% YES — invalid if a sudden cold front or significant precipitation event develops within 24 hours.
ECMWF ensemble centroid indicates 30°C+ for Chengdu. Strong warm advection fuels a developing thermal ridge. Over 29°C is a high-confidence play. 95% YES — invalid if unexpected cold advection occurs.
