Latest ECMWF and GFS ensemble forecasts point to a Chengdu high of 20-21°C on March 24, driven by southerly winds advecting mild air masses post-cold front, fueling trader optimism for 21°C+ at 27% implied probability amid low cloud cover expectations. However, closely matched odds across 11-21°C reflect model divergence—GFS warmer, ECMWF slightly cooler—and historical March variability, with average highs near 18°C but urban heat island effects often adding 1-2°C. Urban pollution trapping heat differentiates upper bins, while any afternoon shower could cap at 18-19°C; monitor China Meteorological Administration updates for resolution-critical peaks.
