Recent forecasts indicate Chongqing's overnight low on August 28 will likely fall between 27–29°C, with close market-implied odds reflecting uncertainty in the exact minimum. Incoming moisture and scattered thunderstorms or rain are expected to increase cloud cover, limiting radiative cooling while enhancing evaporative effects and moderating temperatures relative to recent hot, clear nights near 29–30°C. High regional humidity and light winds typical of the Sichuan Basin further constrain overnight drops, though model differences in precipitation timing and coverage create the narrow spread among leading outcomes. Updated runs from agencies like the China Meteorological Administration and international ensembles will clarify resolution criteria over the next 48 hours.
