Latest numerical weather prediction ensembles from global and regional models indicate peak surface temperatures in Chengdu on August 5 clustered in the 32–35 °C range, driving the tight distribution of market-implied probabilities across 33–35 °C+ outcomes. Subtropical monsoon humidity and soil moisture limit afternoon radiative heating while favoring scattered convection that can cap extremes below 36 °C, consistent with historical August highs averaging 30–34 °C. Light steering winds and urban heat-island effects add modest upward bias, yet model spread remains sensitive to exact timing of any cloud build-up or brief showers. Updated CMA guidance and 48-hour ensemble runs ahead of resolution will likely refine the final distribution as the event window narrows.
