Forecast models for Chengdu on September 5 show a narrow range of daily maximum temperatures centered on 33–35 °C, with limited precipitation and partly cloudy skies under residual subtropical high influence. This produces closely matched market probabilities for 34 °C and 35 °C as the leading outcomes. Local guidance from the Chengdu Meteorological Bureau emphasizes 32–33 °C with increasing cloud cover, while some international ensembles indicate potential for brief afternoon warming to 35 °C or slightly above before the Huaxi autumn rain pattern strengthens later in the week. Key variables include model spread on boundary-layer mixing and exact timing of increasing moisture, with updated numerical guidance and official China Meteorological Administration briefings expected to refine the peak value ahead of resolution.
