**Forecast models and official outlooks indicate Wuhan will remain under a persistent subtropical high-pressure ridge on August 28, supporting afternoon highs in the mid- to upper-30s °C amid continued post-Sanfu heat.** Local meteorological guidance projects 34–37 °C with partly cloudy skies and scattered showers or thunderstorms that could cap peak readings if convection develops early. Recent observations show daily maxima of 36–38 °C, consistent with the fifth-hottest Sanfu period since 1961, while ensemble guidance highlights modest cooling potential from increased boundary-layer moisture and light northeasterly flow. The spread across forecast highs (roughly 34–37 °C) creates genuine uncertainty across the 34–38 °C bins, as small shifts in cloud timing or storm initiation can alter the daily maximum by 1–2 °C. Updated model runs and the official China Meteorological Administration briefing on the 27th will provide the key data ahead of market resolution.
