Official National Weather Service observations recorded a maximum temperature of 81°F in Denver on October 2, 2026, at 2:07 PM local time under clear skies and dry conditions, aligning precisely with the market's 80-81°F resolution and driving the 100% implied probability. This reading exceeded the 1991-2020 climatological normal of 72°F by 9 degrees, reflecting persistent above-average warmth across the Front Range without significant cloud cover or precipitation to moderate daytime heating. Trader consensus reflects confidence in the authoritative NWS station data, with no model uncertainty remaining post-observation. Realistic challenges would require revised official measurements or station-specific discrepancies, though such adjustments are rare once preliminary climatological reports are issued.
