Trader sentiment on Shanghai's highest temperature March 25 tightly clusters around 15-17°C, driven by converging global ensemble forecasts from ECMWF and GFS models projecting peaks near 16.5°C amid mild southerly flow. Late March climatology in Shanghai averages 15-18°C highs, with current jet stream positioning over East Asia suppressing extremes and favoring this narrow band. Differentiating factors include low model spread (standard deviation ~1.5°C), urban heat island effects boosting city readings 1-2°C above rural stations, and minimal cloud interference per satellite data. Recent runs discount 20°C+ outliers (1.8% odds) due to cooler East China Sea surface temperatures, while CMA updates tomorrow may refine hourly maxima ahead of verification.
