Recent forecasts from multiple models indicate Qingdao will experience partly to mostly cloudy conditions on September 23 under southerly flow, with daytime highs most likely reaching 25–27°C as a seasonal cooling trend follows warmer, sunnier days earlier in the week. This positions the 27°C outcome near the center of current guidance, while the slight edge for 31°C or higher reflects residual model uncertainty around cloud thickness and any late-day clearing that could allow brief warming. Lower probabilities assigned to 26°C and below align with the consensus against significant marine-layer strengthening or increased precipitation before the period ends. Updated runs from agencies like the China Meteorological Administration and global ensembles will clarify whether modest warming or persistent cloud cover tips the daily maximum across the closely bunched 27–30°C thresholds.
