Trader consensus on Polymarket prices a razor-thin contest between 22°C (30%) and 23°C (32%) for Shanghai's highest temperature at Pudong International Airport on May 3, driven by conflicting short-range forecasts from the China Meteorological Administration (CMA) projecting an overcast day with westerly winds at 16-24 km/h capping highs near 21°C after May 2's light-to-moderate rain, contrasted by international models like those implied in AccuWeather showing potential for 25°C if partial clearing occurs. Early May climatology at Pudong averages 23°C highs, but persistent cloud cover limits solar insolation and boundary layer heating, creating model divergence on peak afternoon temperatures. New CMA advisories expected later May 2 could sharpen this uncertainty before resolution via finalized Wunderground observations.
