Recent forecasts from the China Meteorological Administration point to persistent low-level cloud cover and light drizzle over Chongqing on May 17, sharply limiting daytime solar heating and anchoring the official maximum near 23 °C at the Jiangbei International Airport station. This stable atmospheric setup, typical of the region’s subtropical spring pattern with high humidity and orographic influence from surrounding mountains, has driven the market-implied probability for a 23 °C peak above 99 percent. Traders appear confident because official observations through the day have remained within a narrow range, with only modest variability expected before the measurement window closes. A late-day clearing that allows stronger insolation or an unanticipated shift in the steering flow could push readings slightly higher, though current model consensus shows little support for such a change.
