Trader consensus on Polymarket overwhelmingly backs a 22°C high in Chengdu on March 20 (92.6% implied probability), driven by the latest numerical weather prediction models from China's Meteorological Administration and ECMWF ensembles, which consistently forecast mild highs under a persistent high-pressure ridge and lingering El Niño warmth. Radiosonde data from nearby stations and satellite-derived cloud cover metrics support this, showing minimal convective activity or cold air advection, aligning with Chengdu's March climatology of 16-22°C peaks. Realistic challenges include a sudden shortwave trough introducing cloudiness or northerly winds, potentially limiting peaks to 20-21°C as in similar 2023 events, though model spreads indicate under 5% odds for such divergence.
