Official National Weather Service observations recorded a daily maximum of 93°F at Denver International Airport on September 4, 2026, placing the outcome firmly in the 92-93°F range. This value exceeded the 1991-2020 normal high of 84°F by 9°F amid a warm, dry air mass with light winds, minimal cloud cover, and no precipitation—conditions consistent with late-summer high-pressure dominance across the Front Range. Traders priced near-certainty into this bin once preliminary climate reports confirmed the reading, reflecting the reliability of station data for market resolution. Only major post-observation revisions or station-specific adjustments could realistically alter the outcome, though such changes are uncommon for verified NWS maxima.
