Trader consensus on Polymarket assigns a 100% implied probability to an 18°C high temperature in Wuhan on April 14, backed by finalized observational data from the China Meteorological Administration (CMA) at Wuhan Tianhe International Airport—the market's official resolution source. Hourly records show the peak reached 18°C midday under overcast conditions and light northerly winds from a passing cool front, capping warming despite typical April climatology averaging 22°C highs. Pre-day ensemble forecasts from ECMWF, GFS, and CMA had converged near 20°C, but real-time soundings confirmed cooler mid-level air. Realistic challenges include rare post-day data revisions for sensor errors, though CMA protocols make this improbable as observations finalize by evening.
