Forecast models from agencies including the China Meteorological Administration and international ensembles show diurnal heating under partly cloudy conditions likely producing a maximum near 30–32°C in Zhengzhou on August 10, with isolated late-day thunderstorms introducing modest cooling potential. This tight clustering around 31°C or 32°C+ reflects the narrow spread in current guidance, as recent surface observations indicate temperatures tracking seasonal norms of about 30°C amid typical East Asian monsoon moisture and light winds. Key differentiating factors include afternoon convective development versus clearer skies that could allow slightly higher peaks, while urban heat-island effects in the city center add a small upward bias to official station readings used for resolution. Updated model runs and satellite trends over the next 12–24 hours will clarify whether instability suppresses or permits the higher end of the range.
