Latest forecast models from sources including the China Meteorological Administration and global ensembles point to an overnight low near 20°C in Chongqing on October 10, driven by persistent cloud cover, high humidity near 80-90%, and light variable winds that limit radiative cooling. These conditions align with the market's leading 45% implied probability for exactly 20°C, while cooler outcomes like 16-17°C carry lower odds due to the absence of strong cold-air advection or clear skies. Warmer thresholds above 24°C remain possible only if daytime heating lingers unusually late, but current guidance favors stabilization in the low 20s Celsius. Updated model runs expected overnight will refine the exact minimum ahead of market resolution.
