Official observations from Austin-Bergstrom International Airport (KAUS), the market's resolution source, confirm the highest temperature on April 28, 2026, reached 89°F around 5 PM CDT, driving trader consensus to 100% on the 88-89°F outcome. National Weather Service forecasts had converged on upper-80s highs amid a southerly flow bringing hazy skies and partial cloud cover that capped solar heating, despite a broader warming trend in Central Texas. Model ensembles from NOAA accurately captured this moderation from earlier projections nearing 90°F+. Realistic challenges are minimal post-event but could include rare data revisions from quality control audits; final National Weather Service climatological reports, expected soon, will solidify this.
