Trader consensus heavily favors a Shanghai high of 12°C (66.5% implied probability) based on the latest forecasts from China's Meteorological Administration and global models like ECMWF and GFS, which project daytime highs peaking near 12°C amid lingering cool northerly winds and partial cloud cover following a recent cold snap. Supporting data shows March 18 highs around 11-12°C with overnight lows near 7°C, aligning with seasonal norms where mid-March averages hover at 12-13°C but current upper-air patterns suppress warming. Lower odds for 13°C (25.5%) or 14°C+ (4.7%) reflect model divergence on afternoon insolation, while sub-12°C outcomes trail due to expected diurnal warming; watch CMA's evening update for potential shifts.
