**Trader sentiment for Chongqing's October 12 lowest temperature centers on incoming cold air and a shear line triggering cooling and scattered rain, with official forecasts pointing to overnight lows near 19–20°C.** Multiple models show the minimum falling to around 19°C amid persistent cloud cover that limits radiative cooling, while light winds and high humidity in the Sichuan Basin moderate sharper drops. Recent updates from local meteorological agencies highlight a shift from warmer prior days, with daytime highs near 25°C giving way to cooler nights. This aligns with market-implied odds clustering tightly around 18–20°C, reflecting genuine uncertainty in precise model outputs and local station variations rather than a strong consensus on any single value. Updated observations through the evening will clarify whether the low settles at 19°C or edges lower.
