National Weather Service forecasts project a high temperature of 80°F at Houston's William P. Hobby Airport (KHOU) on April 11, 2026, driving trader consensus to 98.6% implied probability for 76°F or higher, backed by GFS and ECMWF ensemble agreement on 77-81°F amid building high pressure and warm, humid southerly flow. Current observations show morning readings around 71°F under mostly cloudy skies with east-southeast winds at 7 mph, leaving ample daytime heating potential despite 20-60% scattered shower chances. Realistic challenges include persistent heavy thunderstorms or thickening marine stratus capping insolation, though model runs indicate low likelihood; monitor hourly NWS updates and live KHOU data for intraday shifts.
