Latest ensemble forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) and China Meteorological Administration drive the 75% implied probability for Chengdu's March 24 high reaching 21°C or higher, projecting daytime maxima of 22-24°C under persistent high-pressure ridging and southerly winds advecting warm air from the Yangtze basin. Historical March highs average 17-19°C at Chengdu's Longquan station, but recent observations show a +3-5°C anomaly fueled by low cloud cover and urban heat effects. Lower probabilities for 19-20°C (22% combined) stem from minor model spread introducing possible afternoon clouds, with negligible odds below 17°C absent any cold front intrusion, per GFS updates as of March 23.
