Recent National Weather Service and ensemble forecast guidance from the GFS and ECMWF models indicate Houston will reach a high near the climatological normal of 87°F under continued subsidence and mostly sunny skies, driving the strong market consensus for 86°F or higher. Light southerly winds and low morning humidity are supporting efficient daytime heating with minimal cloud interference expected through peak afternoon hours. This aligns with the ongoing warm pattern that produced multiple upper-80s and low-90s readings earlier in the month, while the narrow spread in latest model runs reduces downside risk to the mid-80s. Traders are monitoring the final 12Z updates and evening soundings ahead of tomorrow’s resolution, with any unexpected increase in onshore flow or convective activity the primary variables that could shift outcomes.
