Latest ensemble forecasts from global models including GFS and ECMWF, aggregated by services like Weather.com and AccuWeather, project Shanghai's May 4 high temperature clustering around 23-26°C, driving the tight market-implied odds favoring 22-24°C outcomes. Recent observations show May 1 highs near 25°C under clear skies, with May 2 trending similarly at 25°C before partial cloudiness on May 3 potentially moderating diurnal heating. Key differentiators include light southerly winds (5-10 mph SSW) and afternoon cloud development, which could suppress peaks to 22°C if thicker cover persists or permit 24°C with more solar insolation. Early May climatology averages 23-24°C highs, underscoring inherent forecast uncertainty; watch China Meteorological Administration updates and tomorrow's model runs for shifts ahead of official station measurements.
