Recent forecasts from the Chengdu Meteorological Bureau and global models indicate the highest temperature on September 7 will likely reach 33–35°C under lingering subtropical high pressure, the so-called “autumn tiger” pattern, before a cold front increases cloud cover and brings scattered showers later in the day. Official outlooks cite daytime maxima of 34–35°C with partly cloudy skies and minimal precipitation early, while ensemble guidance shows slight cooling if rain arrives earlier or intensifies. This distribution of model solutions—centered near 33–34°C but with tails toward 32°C or 35°C—explains the market’s spread, as traders weigh the timing of frontal passage against current heat persistence and historical September maxima around 32°C. Updated CMA briefings and afternoon model runs will be key.
