Recent meteorological forecasts from China's national weather service indicate a daytime high of 28°C for Wuhan on May 17, driven by stable high-pressure conditions and light southerly winds that limit heat accumulation. Ensemble models show tight agreement around this value, consistent with mid-May climatology for the Yangtze River valley where typical maxima fall between 26–29°C. The market's near-100% implied probability on 28°C reflects traders' assessment of these consensus projections and limited upside risk. An unexpected surge in solar insolation or a late-developing warm front could still push readings to 29°C or above, though current guidance assigns low odds to such deviations before resolution.
