Traders assign a 99.8% implied probability to a 22°C high in Shanghai on June 14, reflecting real-time observational data from regional meteorological networks showing daytime maxima capped near this level amid persistent cloud cover, light easterly flow, and plum-rain season moisture. Official short-term guidance indicates limited diurnal heating under overcast skies, consistent with early-summer Yangtze Delta climatology where June averages hover near 27–28°C but individual days with high humidity often peak lower. This market consensus incorporates live station readings and model agreement that further warming is unlikely before evening. A late-afternoon clearing trend or localized measurement adjustment could still alter the final recorded maximum, though such shifts remain low-probability given current atmospheric conditions.
