Official National Weather Service data from the Austin-Bergstrom International Airport station (KAUS) confirms the highest temperature on April 4, 2026, reached 78-79°F, as detailed in the preliminary daily climatological report (CLI) issued overnight, solidifying trader consensus at 100% implied probability for this outcome. Morning temperatures started in the 50s under partly cloudy skies with light southerly winds fostering moderate warming, peaking mid-afternoon before incoming storms and increased cloud cover capped further rises, aligning with forecast model consensus from NOAA sources. This positioning reflects the reliability of ASOS observations, with historical April 4 normals around 77°F. Realistic challenges are negligible—only a verified sensor malfunction or post-audit revision by NWS climatologists could shift it, though quality controls make this improbable; watch for the monthly climate summary next week.
