Official National Weather Service observations for Denver on September 28 recorded a daily maximum of 71°F under cloudy conditions with light rain and a modest southerly flow, aligning closely with the 68–69°F market bin at full consensus. This outcome reflects direct station data from Denver International Airport, consistent with regional model guidance showing limited diurnal warming amid elevated moisture and a passing frontal boundary that suppressed temperatures several degrees below the 74°F seasonal normal. With the observation period now closed, no further model revisions or measurement adjustments can alter the result, though traders would have monitored real-time ASOS updates and preliminary climate summaries for confirmation. Historical analogs indicate September highs near 74°F on average, underscoring how the observed cool anomaly locked in the narrow range.
