Recent National Weather Service observations and model guidance for central Texas on September 28 indicated a maximum of 96–97 °F at Austin-Bergstrom International Airport under partly cloudy skies, southeasterly flow, and dew points in the upper 60s that limited afternoon mixing. This aligned with climatological norms for late September and short-range ensemble consensus showing no strong warm-air advection or subsidence to push readings higher. The 100 % market-implied probability for this narrow bin reflects traders’ confidence in the verified official reading once preliminary data confirmed the peak occurred near 3:36 PM CDT. A last-minute model shift, station instrumentation revision, or microscale urban heat-island effect exceeding 1–2 °F could still alter the final certified value before resolution.
