Todays weather in Houston Texas - Thursday - 28 May 2026

An Air Quality Alert is active in Houston today, and if you're stepping outside — especially if you have asthma, allergies, or any respiratory sensitivity — this briefing is your essential 3-minute prep.Patchy morning fog will linger until around 9 a.m. before burning off to mostly sunny skies. But the air quality issue is separate from the fog and more persistent: with winds near zero to five miles per hour out of the north, the atmosphere simply isn't moving, trapping pollutants close to the ground. Limit outdoor time during midday peak hours if you can.Temperatures top out near 88°F today with humidity firmly in place and only a 12 percent chance of rain — you won't get wet, but you'll feel the heat. Tonight clears nicely to a low around 73°F with a light south breeze.Looking ahead, this pattern holds right through the weekend. Friday returns with patchy morning fog and a high near 90°F. Saturday and Sunday both reach 91°F. The stagnant air means that air quality concern could linger all weekend. Monday marks a shift, with showers and thunderstorms becoming possible — and by Tuesday, rain chances climb to 35 percent. That's the first meaningful rain threat in days.Today's bottom line: dress light, skip the outdoor workout if your lungs are sensitive, allow extra commute time while the morning fog clears, and keep Tuesday on your radar if you have plans that run into next week.This episode includes AI-generated content.
