The National Weather Service official climate summary for Dallas/Fort Worth recorded a maximum temperature of 86°F on October 5, 2026, observed at 3:48 PM under clear skies with light northeast winds and no precipitation. This value aligns precisely with the market's dominant 86-87°F outcome at 100% implied probability, reflecting trader consensus on verified observational data rather than forecasts. The reading sits 3°F above the 1991-2020 normal high of 83°F yet well below the date's all-time record of 97°F, consistent with recent model guidance showing stable high-pressure conditions. Resolution criteria focus on the official NWS maximum at the primary station; alternative station readings or post-analysis revisions remain the only realistic paths to a different outcome, though historical precedent indicates such adjustments are rare for this metric.
