Latest short-range forecasts from regional meteorological models indicate a daily minimum temperature in Chongqing near 24–25°C on September 27, supported by persistent cloud cover, high humidity near 80%, and light northerly winds that limit nighttime radiative cooling. Scattered showers and a moderating southerly flow keep conditions mild, aligning with late-September climatology where typical lows range 21–23°C. No strong cold advection or clear-sky conditions are expected to drive sharper drops. Official China Meteorological Administration updates and final model consensus before resolution will clarify any micro-scale variations across the municipality, sustaining trader focus on the 24°C outcome while the 19°C-or-below and warmer bins reflect remaining forecast spread.
