**Official National Weather Service observations recorded a daily maximum of 92–93 °F at Denver’s primary reporting station on June 17, 2026, matching the pre-event model consensus.** A strong high-pressure ridge promoted clear skies, strong solar heating, and downslope warming along the Front Range, pushing temperatures well above the 83 °F climatological normal. Multiple NOAA and private forecast runs converged on low-90s readings with little spread, eliminating realistic pathways to either sub-90 °F or 94 °F-plus outcomes once the day began. The 100 % market-implied probability therefore reflects verified post-event data rather than forecast uncertainty, though minor station-to-station micro-climate differences or measurement revisions could theoretically alter resolution in edge cases.
