Official observations from National Weather Service stations, including Austin Bergstrom International Airport, recorded a daily maximum of 91–92°F on October 7, 2026, under clear skies with light northeast winds and low humidity. This placed the high well above the 1991–2020 normal of 85–86°F but within the narrow 90–91°F bin that captured the precise peak reading used for market resolution. Strong model consensus from the prior 48 hours and absence of any frontal passage or cloud cover supported the outcome, aligning with recent warm October patterns across central Texas. A measurement revision from an alternate station, revised quality-control adjustment, or use of a different official site could shift the final bin, though such changes remain unlikely after preliminary climatological reports.
