Trader consensus has converged on a 100% implied probability for 26°C as Wuhan's highest temperature on May 9, backed by real-time METAR observations from Wuhan Tianhe International Airport (ZHHH), the market's official resolution source, which recorded a peak of 26°C (78°F) during afternoon hours under partly cloudy skies, moderate 50% relative humidity, and light northerly winds. This aligns with China Meteorological Administration forecasts and ensemble guidance from GFS and ECMWF models, which projected maxima in the 25–28°C range amid a stable high-pressure ridge following recent cooler weather on May 8 (22°C high). Current evening readings near 19°C with clear conditions preclude further heating. Realistic challenges would require an official data revision or anomalous late-day spike from unforecast downslope effects, both exceedingly unlikely as solar insolation wanes. The China Meteorological Administration's daily summary, due post-midnight, will confirm resolution.
