Persistent cloud cover, light to moderate rain, and high humidity across Chongqing on October 14 are moderating diurnal temperature swings and anchoring the overnight low near 20°C, according to consensus from regional forecast models. These conditions limit radiational cooling under a subtropical airmass with light northeasterly flow, keeping minimums from dropping sharply while also capping daytime peaks. Official station readings will resolve the market, and slight differences in model timing of showers or boundary-layer moisture explain the tight clustering around 18–20°C outcomes. Historical mid-October baselines in the region show similar mild lows under comparable synoptic patterns.
