Recent forecasts from agencies including the Jinan Meteorological Bureau and international models point to an overnight low near 21–22°C on August 28 under mostly cloudy skies with scattered showers and thunderstorms, which moderate radiative cooling and explain the tight clustering of market-implied odds around 20–21°C. Light northerly winds and high humidity near 80% further limit temperature drops, while urban heat effects at the official station introduce small uncertainty between those two values. Historical late-August climatology shows typical lows of 21–23°C, and the absence of clear-air conditions or stronger cold advection keeps probabilities for 19°C or below low. Updated model runs and official minimum readings expected by early morning will provide final resolution data.
