Latest National Weather Service guidance and ensemble model consensus from GFS and ECMWF project a high temperature near 82°F at Houston's William P. Hobby Airport (KHOU) on April 13, driving trader sentiment toward 80°F or higher at 81.5% implied probability. This reflects building high pressure over Texas following scattered showers and thunderstorms on April 12, with partial clearing, warm advection, and light southeasterly winds supporting highs in the low 80s amid above-normal April conditions—recent daily maxima reached 82°F on April 9 and a record 86°F earlier. Lingering clouds or isolated storms could cap peaks at 78-79°F (13.5%), per model spread; new forecast updates and evening model runs will refine uncertainty ahead of resolution using official KHOU observations.
