Official National Weather Service observations recorded a maximum temperature of 86°F in Denver on September 8, 2026, at 3:31 PM MDT, aligning precisely with the market's 86-87°F resolution and 100% implied probability. This value exceeded the 1991–2020 climatological normal of 83°F by 3°F under partly cloudy skies with light winds and no significant precipitation, consistent with seasonal late-summer patterns influenced by high-pressure dominance and downslope warming. Trader consensus reflects the definitive post-event data release rather than forecasts, as the climatological report issued that evening confirmed the reading from the Denver International Airport station. While rare revisions to preliminary observations or station-specific adjustments could theoretically alter the final value, the close agreement across multiple NWS updates and historical analogs makes such shifts improbable once the report is finalized.
