Houston, TX – Morning humidity clings to the air across Southeast Texas this Sunday, with a warm haze hinting at another steamy day ahead. But change is on the way — subtle shifts in Gulf moisture will bring light showers Tuesday before a cooler, drier Halloween weekend sets in for Houston and nearby suburbs.
According to the National Weather Service, Sunday stays mostly cloudy near 80°F before skies clear Monday. Winds will remain light out of the north, keeping conditions warm but calm. By Tuesday, a weak disturbance moves in from the Gulf, sparking scattered showers and isolated thunderstorms mainly through the afternoon and early evening. Roads along I-45 and Beltway 8 may become slick during rush hour, so drivers should plan extra time.
Temperatures dip slightly midweek, with highs around 83°F Tuesday and cooling to the upper 60s by Wednesday night. Dry air then dominates through Thursday and Friday, setting the stage for a near-perfect Halloween night — clear skies, light breezes, and readings near 67°F at sunset. Costumes with lighter sleeves should be fine early, but parents may want a jacket handy as evening winds pick up.
By Saturday, highs settle near 78°F under bright skies — ideal for post-Halloween events or early fall decorating. Models suggest the first true cool front could arrive next week, signaling the start of a mild but unmistakably chilly November ahead.
