Current ensemble forecasts from global and regional models indicate a probable daily maximum near 34–35 °C for Chongqing on August 18, with scattered thundershowers and increased cloud cover expected to moderate peak heating. Subtropical monsoon conditions, high humidity, and local orographic effects around the Yangtze and Jialing river valleys create sensitivity to the exact timing and coverage of convection, producing the tight market clustering between 34 °C and 36 °C. Official guidance from the China Meteorological Administration and international centers will update through the next 48 hours; any shift in storm initiation or steering flow could alter the realized high by 1–2 °C and shift implied probabilities accordingly.
