Trader consensus on Polymarket assigns a near-certain implied probability to a 22°C high in Chengdu on April 30, backed by China Meteorological Administration observations at Shuangliu International Airport showing midday peaks near 21°C amid persistent overcast skies, 99% cloud cover, and north-northeasterly winds that curb solar insolation and convective heating. ECMWF and GFS ensemble forecasts align with a maximum of 22–23°C under this cooler synoptic pattern, diverging from April's typical 23–24°C average due to incoming light rain suppressing further warming. Final CMA data after midnight will confirm resolution; a sudden cloud break enabling brief insolation spikes could realistically push to 23°C, though model uncertainty ranges deem this low-probability.
