The Houston area will have another hot day with potential ozone issues this Thursday. Gulf breeze will strengthen over the weekend and could pave the way for more rain next week.
Houston will have another hot day and potential air quality issues this Thursday, after Wednesday recorded unhealthy ozone levels in the city.
The forecast calls for highs in the low 90s Fahrenheit, with abundant sunshine for much of the day. Conditions could favor new ozone problems in Houston-area neighborhoods, especially near and north of Interstate 10.
Ground-level ozone can irritate the lungs and cause dry coughs or asthma attacks in sensitive individuals, including children, older adults, and residents with respiratory illnesses.
Ozone can affect people with asthma or breathing problems
Air quality should improve during the morning, but afternoon conditions could allow ozone pollution to form again.
The day began with temperatures in the mid to upper 60s Fahrenheit. Humidity near 100% could also produce light fog in some areas, especially outside Houston.
As the day progressed, the sun and light southerly winds can contribute to surface ozone formation. This type of pollution is not always visible, but it can be felt by people with respiratory sensitivity.
People with asthma, lung disease, older adults, children, and those who work outdoors can reduce exposure by avoiding strenuous activities during the hottest and most polluted hours.
Those with symptoms such as persistent coughing, chest pressure, shortness of breath, or strong irritation should follow their doctor’s instructions and seek care if symptoms worsen.
Gulf breeze will help clear the air over the weekend
Conditions will start to change on Friday, when the Gulf breeze strengthens. That air flow will help improve air quality in Houston and reduce ozone problems over the weekend.
The increased wind will also bring more humidity to the area. For Saturday and Sunday, small chances of rain are expected, 10% on Saturday and 20% on Sunday, according to the local forecast.
Humidity will be more noticeable by Sunday. Although the air will feel heavier, the stronger winds could partially offset that sensation. Gusts could reach up to 40 mph at times.
The shift in pattern will also mark the start of a more active week in the forecast. The arrival of more Gulf humidity will set the stage for more widespread rainfall.

Wider rains could reach Southeast Texas next week
Local meteorologists are monitoring a system in the upper levels of the atmosphere that could affect Southeast Texas starting Monday and into much of the workweek.
Details may still change, but the forecast holds rain chances between 40% and 60% for several days next week. The rains could arrive accompanied by thunderstorms in parts of the area.
The updated forecast for Houston shows highs of 93°F this Thursday and 88°F on Friday. For Saturday and Sunday, storms are expected in parts of the area, with highs between 86°F and 87°F.
The rainfall trend continues for Monday, Tuesday and Wednesday, with highs in the mid-80s Fahrenheit and conditions favorable for showers or thunderstorms.
Heat, humidity and air quality define the end of the week
The weekend closing will combine heat, humidity and changes in air quality. Thursday will be the day with the most ozone attention, while Friday and the weekend will bring more wind from the Gulf.
On days with ozone alerts, sensitive individuals can check local alerts before going out, limit intense outdoor exercise in the afternoon, and keep respiratory medications on hand if they use them under medical guidance.
Drivers and outdoor workers should also take breaks, drink water, and avoid staying outdoors for long periods under the sun during the hottest hours.
The forecast remains for heat this Thursday, stronger gulf breeze over the weekend, and a higher chance of rain for Houston and Southeast Texas in the coming week.
