China Meteorological Administration hourly observations from Shanghai's primary stations, including Xujiahui, confirm a midday peak of 22°C today, with temperatures falling amid evening cloud buildup and light southerly winds. This aligns with pre-dawn ensemble forecasts from ECMWF, GFS, and CMA models projecting capped warming under partly cloudy skies and typical late-March atmospheric patterns, where solar heating is moderated by urban heat island effects and sea breezes. The 99.8% market-implied probability reflects this observational consensus backed by real-time data, leaving minimal room for 23°C or higher. A rare clear-sky heat burst before sunset could challenge it, but declining sun angle and humidity make this improbable; final daily report due soon.
