Houston, Texas – Dense haze and near-record heat will grip Houston on Thursday, with temperatures climbing to 91°F and visibility dropping across major roadways including I-10 and I-45. Drivers and outdoor workers are advised to take precautions as stagnant air and rising pollution levels trigger air quality concerns across Southeast Texas.
According to the National Weather Service, widespread haze will develop Thursday morning, becoming most noticeable by noon as south winds remain calm at 5 mph. This stagnant pattern — driven by a ridge of high pressure — will trap pollutants near the surface. Sensitive groups, including children and those with respiratory issues, should avoid prolonged outdoor activity.
Heat will intensify into the weekend. Thursday’s high reaches 91°F, but Friday and Saturday could peak at 94°F. Combined with the haze, conditions may feel oppressive, especially in urban areas. Houston ISD has not announced any schedule changes, but officials are urging limited recess and after-school outdoor events.
Showers may offer some relief Friday night into early Saturday, but chances remain low at 20%. Until then, residents are urged to stay hydrated, check on vulnerable neighbors, and limit strenuous activities outdoors between 11 a.m. and 4 p.m.
More advisories are possible as haze lingers through Saturday.
