**Official forecasts from the Wuhan Meteorological Observatory drive the overwhelming 95.5% market-implied probability for a 35°C high on August 23.** The agency issued a high-temperature yellow warning at 6:50 a.m. local time, projecting most areas would reach or exceed 35°C with localized peaks near 37°C under partly cloudy skies and scattered showers or thunderstorms. Multiple numerical models and real-time observations align on an afternoon maximum around this threshold, consistent with typical late-August climatology for the Yangtze River region where daytime heating peaks before evening convection or northerly winds moderate conditions. A realistic challenge would require stronger-than-expected insolation, delayed showers, or revised observational data pushing the official recorded high to 36°C, though current guidance and timing of precipitation keep that outcome low-probability. Traders appear to treat the authoritative forecast as the most likely resolution outcome given the market's tight clustering.
