Recent observational data and forecast model consensus from sources including the China Meteorological Administration point to a daily high of exactly 27°C in Chongqing on September 13, underpinning the market's near-certain implied probability. Overcast skies, light variable winds, and moderate humidity around 60-70% have limited further warming while preventing significant cooling, aligning with typical mid-September conditions for the region where average highs hover near 26-29°C. Official station reports through the afternoon have consistently registered this peak without upward revisions. Only a late-day measurement error, post-closure data adjustment, or highly localized microclimate anomaly at the primary reporting site could realistically alter the outcome before final verification.
