TCEQ Daily Air Quality Forecast Update

Light winds, warm temperatures, sufficient afternoon sunshine, and/or elevated incoming background levels may be enough for ozone to reach the middle of the “Moderate” range in parts of the El Paso and Houston areas, the lower end of the “Moderate” range in parts of the Austin, Bryan-College Station, Corpus Christi, Dallas-Fort Worth, Midland-Odessa, San Antonio, and Waco-Killeen areas, and the upper end of the “Good” range for the majority of the Amarillo, Beaumont-Port Arthur, Lubbock, and Victoria areas, with the highest concentrations expected in the afternoon and evening.

Northerly winds will persist in the eastern two thirds of Texas as the cold front exits into the Gulf of Mexico and Lower Mississippi Valley. Light to moderate smoke is anticipated to remain over most of Texas, possibly with higher surface concentrations as building high pressure increases subsidence. Light morning winds could contribute urban fine particulate matter in the North Central and Northeast regions, but any effects are likely to be limited to the most populated areas. Overall, the daily PM2.5 AQI is forecast to reach the upper end of the “Good” range for the majority of the Austin, Beaumont-Port Arthur, Corpus Christi, Dallas-Fort Worth, El Paso, Houston, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas.
