**Trader sentiment for Shanghai's June 18 daily maximum centers on the latest forecast models showing persistent overcast skies and isolated thunderstorms, which limit solar heating and keep the peak near 27–28°C.** These conditions suppress daytime temperature rise compared with clearer scenarios, aligning with typical June averages of 27–30°C under humid, plum-rain-influenced patterns. The close spread between 27°C (41.5%) and 28°C (32.5%) reflects uncertainty in the precise timing and intensity of any brief cloud breaks or light rain, which can shift the recorded high by 1°C. Official readings from the China Meteorological Administration station network will determine resolution, with traders weighting recent model consensus over longer-term climatology.
