Latest China Meteorological Administration guidance, updated at 8:00 AM on April 3, projects Shanghai's highest temperature on April 5 at 23°C under overcast skies, aligning with the market's leading trader consensus where 23°C (24%) edges 24°C (22.5%) and 25°C (17.5%). Ensemble forecasts from ECMWF and GFS models show a tight spread around 23-25°C, driven by persistent low-level cloud cover from a lingering frontal system over the East China Sea, which caps solar heating despite mild southeasterly flow. Differentiation hinges on potential breaks in overcast conditions allowing extra insolation for 24-25°C, versus thicker clouds holding at 22-23°C; historical April highs average 18-20°C, but current synoptic patterns favor the warmer side. Traders await afternoon CMA updates and evening model runs for resolution clarity.
