Latest China Meteorological Administration (CMA) guidance and global forecast models like GFS and ECMWF show consensus for a Shanghai high temperature around 25°C today, positioning it as the market's leading outcome at 40% implied probability, with 24°C (29.5%) and 26°C (21%) close behind. Partial cloudiness lingering from yesterday's early showers caps solar insolation, limiting daytime heating, while light northerly winds at 15-20 km/h moderate the boundary layer after recent highs near 24°C. Mid-May historical averages hover at 25-26°C amid East Asian monsoon transition and urban heat effects from Shanghai Pudong station observations. Uncertainty stems from potential afternoon clearing boosting to 26°C+ or enhanced sea breeze cooling to 24°C; watch CMA's evening update and hourly data for resolution shifts.
