Numerical weather prediction models from the China Meteorological Administration and global ensembles show a daytime high near 30°C for Wuhan on May 16, driven by moderate southerly flow across the Yangtze River basin and partial cloud cover that limits peak solar heating. Ensemble spread arises mainly from uncertainties in afternoon humidity levels near 75 percent and the exact timing of any scattered showers, which could suppress the maximum by 1–2°C or allow brief clearing to push readings to 31°C. This transitional May pattern aligns with historical averages of 26–29°C for the date, though recent days have trended slightly warmer. Traders therefore assign the highest implied probability to 30°C while keeping 31°C close behind, pending final hourly observations from Wuhan Tianhe International Airport.
