The market has converged on a highest temperature of 76-77°F in Denver on May 16 because official National Weather Service observations recorded a daily maximum squarely in that range under stable high-pressure conditions and typical mid-May westerly flow along the Front Range. These verified readings eliminate model uncertainty and directly match the resolution criteria, leaving negligible room for outcomes above 78°F. Historical climatology for the period shows average highs near 72°F, so the modest above-normal warmth aligns with current seasonal baselines without triggering any record or anomaly flags. Only an unexpected late-day thermal spike or post-observation data revision could alter the result, but no such developments have appeared in monitoring agency reports.
