National Weather Service observations recorded a minimum temperature of 62°F in Denver on September 7, 2026, well above the September normal low near 53°F and far from historical extremes like the 34°F record set in 1929. This outcome aligns with above-average warmth persisting into early September, driven by clear skies, light winds, and minimal nocturnal cooling under high pressure. Trader consensus at 95.5% implied probability for the 64-65°F bin reflects these verified measurements from official stations, with only minor uncertainty from potential microclimate variations or final data revisions. Scenarios that could shift resolution remain limited to late reporting adjustments or alternative station readings outside the primary NWS summary.
