National Weather Service observations confirm Houston's William P. Hobby Airport (KHOU) recorded a high temperature of at least 90°F on May 13, 2026, under a dominant high-pressure ridge that ensured clear skies, light winds, and efficient daytime heating from morning lows in the upper 60s to low 70s°F. This exceeded the mid-May climatological normal of 87°F, aligning with forecast model consensus projecting peaks near 91°F and driving trader consensus to 100% implied probability for 90°F or higher. While robust surface and upper-air data support this positioning, realistic challenges include potential data revisions from Weather Underground's final archive or station metadata adjustments revealing a borderline 89°F maximum, though such discrepancies are rare post-preliminary reporting.
