Recent forecasts from Chinese meteorological services and global models show Shanghai under increasing cloud cover with light rain or showers expected on August 28, limiting solar insolation and capping maximum temperatures near 31–32 °C. Persistent easterly flow and elevated humidity further suppress peak heating compared with the prior clear, hotter days around 33 °C. This aligns with the market-implied probabilities, where 31 °C leads at 54.5 % and 32 °C follows at 22.5 %, reflecting model consensus on modest cooling from precipitation timing and coverage. Resolution hinges on the precise hour of maximum temperature and any late-day clearing, both of which remain sensitive to small shifts in steering patterns over the next 48 hours.
