Official observations from Weather Underground at Houston's William P. Hobby Airport (KHOU) confirm the highest temperature on April 15, 2026, reached 82-83°F, aligning with National Weather Service forecasts of partly sunny skies, southerly winds at 5-15 mph gusting to 20 mph, and a building high-pressure ridge over Texas suppressing further warming. Mid-afternoon peak temperatures matched model consensus from GFS and ECMWF runs, which projected low-80s highs amid typical springtime advection of Gulf moisture keeping humidity elevated around 60-70%. Slightly above the 1991-2020 April normal of 79°F, this reflects seasonal climatology without anomalous heat. Realistic challenges would require rare post hoc data revisions from automated ASOS sensors, though such adjustments are infrequent for established daily maxima.
