Official measurements from Houston Hobby Airport, the primary station for local climatological reports, recorded a daily maximum of 91°F on September 9, 2026, at 2:59 PM CDT—precisely within the 90-91°F bin that now carries full market-implied probability. This outcome aligns with near-normal conditions for the date, where the 1991-2020 average high is 90.5°F, and reflects limited afternoon heating amid typical late-summer humidity and partial cloud cover rather than extreme clear-sky radiation. National Weather Service data confirm no higher reading occurred, locking trader consensus around verified observations. Resolution could face challenge only from alternate station data or post-event quality-control revisions, though such adjustments remain rare for this airport site.
