Official National Weather Service observations for Houston on September 10 showed a daily maximum in the upper 80s, aligning with the market's near-certain 88-89°F outcome. Scattered showers, persistent cloud cover, and elevated humidity from an unsettled pattern suppressed afternoon heating, holding readings below the 1991–2020 climatological average high of roughly 90°F. This outcome matches historical analogs for similar late-summer convective days and reflects real-time model consensus that steered temperatures away from the 90–91°F bin. Realistic challenges remain limited to minor post-analysis revisions in official station data or differences across reporting sites, though such adjustments rarely exceed a degree or two once preliminary values are confirmed.
