**Recent forecasts from the Chongqing Meteorological Station indicate that August 28 will feature continued hot daytime conditions (highs 35–38°C) under subtropical high influence, followed by the onset of widespread rain and thunderstorms from the evening onward.** This system, linked to peripheral flows from prior typhoon remnants, is expected to bring mid-to-heavy rainfall (locally 50–80 mm) especially in western areas, initiating cooling overnight. Official guidance projects a daily temperature range of roughly 21–38°C citywide and 27–32°C in the urban core, with the minimum likely occurring late in the period as moisture and incoming cooler air suppress temperatures. **Model consensus and historical August climatology for Chongqing (typical overnight lows 25–27°C) support a narrow band around 27–29°C as the most probable minimum on the 28th, before fuller cooling materializes on the 29th.** The market-implied probabilities—led by 28°C at 51.5%—reflect trader aggregation of these short-term dynamics, where the exact timing of rain onset and cold-air advection introduces modest uncertainty. Newer model runs or official updates from the National Meteorological Center could shift the distribution if precipitation arrives earlier or intensifies more rapidly than currently anticipated.
