HOUSTON, Texas – Dawn breaks warm and muggy across the city this Sunday morning, with clouds hanging low over the skyline and air so thick you can almost feel it. It’s another humid Gulf sunrise — and it marks the start of a week that will feel more like August than late October.
According to the National Weather Service in Houston, high pressure will dominate through midweek, sending temperatures climbing into the upper 80s and even touching 90°F by Monday and Tuesday. Winds will shift southeast, drawing in moist air from the Gulf and keeping humidity levels uncomfortably high. Afternoon heat indices may briefly push into the mid-90s in areas along I-45 and the inner loop.
Tuesday looks to be the week’s warmest day before subtle changes begin midweek. Clouds increase by Wednesday as a weak boundary drifts in from central Texas. While rain chances remain low early, models hint at rising instability by late Thursday into Friday — the first sign of a pattern change that could bring scattered storms and a minor cooldown heading into the weekend.
For now, residents should plan for warm commutes, sticky evenings, and a late-week chance for slick roads if showers do materialize. The next few days will also favor yard work, early Halloween decorating, or outdoor events before humidity peaks again late Thursday. By Saturday, drier air may briefly slip back in, setting up a more comfortable, fall-like close to the week.
