Ensemble forecasts from the China Meteorological Administration, ECMWF, and GFS converge on Shanghai's highest temperature March 30 in the 18–20°C range—above the late-March climatological norm of 17°C under ENSO-neutral conditions—fueling tight trader sentiment with 19°C at 29% implied probability edging 18°C and 20°C at 25% each. A frontal passage ushered northwest winds (16–24 km/h), light rain, and 94% cloud cover, suppressing solar insolation after yesterday's 23°C peak; Xujiahui station logged 16°C by 8 AM. Differentiating factors include afternoon cloud persistence versus thinning during peak heating (2–4 PM local), where overcast skies limit maxima to 18°C but partial clearing enables 20°C via radiative warming. CMA hourly updates will clarify resolution trajectories.
