Recent forecasts indicate a sharp cooldown in Chongqing on September 10 driven by the arrival of cold air after days of “autumn tiger” heat exceeding 38 °C. Official guidance projects a high between roughly 26–34 °C under increasing cloud cover and scattered light rain, with the exact maximum hinging on the timing and strength of the frontal passage, boundary-layer moisture, and any embedded convection that could suppress daytime warming. Numerical models diverge modestly on the peak value, reflecting uncertainty in how quickly the cooler, moister air mass overrides the residual heat and whether measurable precipitation arrives before the daily maximum is reached. Traders are therefore splitting probability across the 29–31 °C range while assigning notable weight to outcomes at or below 23 °C if heavier rain or faster advection materializes. Updated model runs and Chongqing Meteorological Bureau briefings over the next 48 hours will likely narrow the range.
