Latest numerical weather prediction models, including ECMWF and GFS ensembles, project Chengdu's March 23 high temperature around 19-21°C under persistent high-pressure ridging and southerly winds, fueling 68.5% market-implied odds for 19°C or higher as the frontrunner. Recent observations show daytime highs of 18-22°C over the past week, aligning with spring climatology where March averages 17-19°C amid urban heat effects in the Sichuan Basin. The 22% probability on exactly 18°C reflects trader hedging against potential afternoon cloudiness or light showers hinted in some model members, while lower outcomes carry slim odds absent any cold front. Key resolution hinges on official China Meteorological Administration observations at 00Z March 24.
