Latest official forecasts from the China Meteorological Administration and ensemble model runs converge on a peak of 27°C in Chengdu today, driven by stable subtropical high pressure, light southeasterly flow, and typical mid-May insolation levels in the Sichuan basin. This consensus matches historical climatology, where daily highs average 26–28°C under partly cloudy skies with minimal convective activity. Real-time surface observations and satellite data through early afternoon show no significant deviation, supporting the market’s overwhelming 99.8% implied probability for 27°C. A sudden increase in cloud cover or localized showers could cap the reading at 26°C, while stronger solar heating or reduced humidity might push it to 28°C, though both remain low-probability outcomes given current atmospheric stability.
