Recent heavy rainfall and associated cooler air advection from a mid-latitude system have driven down overnight temperatures across Chongqing, shifting trader focus toward a daily minimum of 19–23 °C. Official forecasts from the Chongqing Meteorological Observatory indicate 20–24 °C lows for August 30 amid lingering cloud cover and scattered showers, with model consensus favoring modest further cooling overnight before clearing. Historical late-August baselines near 26 °C have been depressed by 4–6 °C due to the ongoing precipitation event, increasing the implied probability of sub-20 °C readings while limiting upside to 25 °C or higher. Final resolution hinges on the 24-hour minimum recorded at official stations as skies clear into the evening.
