Recent numerical weather prediction models from agencies like the China Meteorological Administration converge on a peak temperature of 28–29°C in Wuhan for May 17, reflecting light southerly flow, partly cloudy skies, and modest afternoon instability. This setup supports gradual daytime warming but introduces uncertainty from potential scattered showers that could suppress maximum heating by limiting solar insolation. Mid-May climatology places historical highs near 27–28°C, providing a stable baseline against which current observations align closely. Traders price the narrow spread between 27°C, 28°C, and 29°C outcomes because minor shifts in cloud cover or convective timing—common in transitional spring patterns—can alter the exact daily maximum by 1–2°C before official station readings finalize.
