Official observations from the National Weather Service confirmed a daily maximum of 86–87°F at the designated Denver station on September 14, aligning precisely with the 100% market-implied outcome for that range. Pre-event forecasts from NOAA anticipated highs near 88–89°F under partly cloudy conditions with limited afternoon heating, but actual readings fell just below due to persistent cloud cover and modest wind patterns that suppressed peak temperatures. Historical September averages near 80°F and the absence of strong downslope warming or clear-sky radiative heating reinforced this outcome. Minor measurement revisions or station discrepancies remain the primary scenarios that could shift resolution, though official data finalized the result with high confidence.
