Official National Weather Service observations from the Automated Surface Observing System at William P. Hobby Airport (KHOU) confirm Houston's highest temperature on March 30 reached 82.9°F at 2:53 PM CDT, locking in the 82-83°F outcome with near-certainty among traders. This peak occurred under partly cloudy skies and southerly winds of 10-15 mph, which advected warm Gulf air into southeast Texas amid a weak high-pressure ridge, pushing readings 6-7°F above the March climatological average of 76°F. Model forecasts from NOAA's Global Forecast System had anticipated this mild warmth in the days prior, aligning trader consensus early. While ASOS data is highly reliable, a rare quality-control revision could theoretically adjust the record, though such changes are exceptional post-finalization.
