**Current atmospheric conditions over eastern China feature stable southerly flow and weak pressure gradients, supporting minimum temperatures near 19–22°C in Qingdao on September 19.** Multiple forecast models consistently project overnight lows in this range under partly cloudy skies, with daytime highs of 25–27°C and light to moderate southeast winds limiting radiative cooling. The market’s near-even split between sub-14°C and 24°C+ outcomes, alongside clustered probabilities around 18–23°C, reflects residual ensemble spread in short-range guidance—particularly regarding possible shifts in coastal marine influence or minor cold-air intrusions. No strong synoptic features, such as typhoon remnants or sharp fronts, are expected to alter this pattern before resolution. Updated model runs from regional meteorological centers will provide the next key data points for refining these temperature thresholds.
