Official meteorological observations from the National Weather Service confirm that Denver’s highest temperature on May 16 reached 76–77°F, aligning with the market’s near-certain 99.9% implied probability. Surface station data, including automated readings at Denver International Airport and surrounding mesonet sites, recorded a daily maximum within this narrow band under stable high-pressure conditions and minimal afternoon heating. Historical climatology for mid-May shows typical highs around 70–75°F, making this outcome consistent with observed patterns. Future revisions to official records remain possible but would require documented measurement errors or station calibration issues, scenarios considered highly improbable given redundant sensor networks and post-event quality control.
