Latest ensemble forecasts from ECMWF and GFS models project Shanghai's nocturnal minimum on May 17 around 18-20°C, fueling trader consensus on 19°C (37%) and 18°C (29.5%) as frontrunners amid a tight spread. Recent clear skies over May 15-16 have enabled radiative cooling to 19-20°C lows, but partial cloudiness and persistent southerly breezes (15-22 km/h) on May 17 may temper further drops by mixing the boundary layer and invoking urban heat island effects. Mid-May climatology averages 17-21°C lows, with uncertainty hinging on overnight wind deceleration and cloud evolution; new 00Z model runs and China Meteorological Administration observations expected within 24 hours could shift the balance.
