Trader consensus on Polymarket has locked in a 100% implied probability for a highest temperature of 20°C in Chongqing on April 20, driven by official observations at Chongqing Jiangbei International Airport—the market's resolution station—confirming this peak amid persistent cloud cover and rainfall from the region's first major spring storm system. China Meteorological Administration data shows widespread showers and thunderstorms since April 19 suppressed daytime heating, with overcast skies limiting solar insolation and southerly flows bringing cooler, moist air under a high-altitude trough. Forecast models from NMC accurately anticipated subdued highs below seasonal norms of 22–25°C. While final daily reports could theoretically revise upward due to station microclimate variations, late-evening readings around 19°C render higher outcomes implausible, solidifying the positioning.
