Forecast Discussion

Light to moderate winds, warm temperatures, abundant afternoon sunshine, and/or increased incoming background levels could be enough for ozone to reach the lower to middle end of the "Moderate" range in parts of the Dallas-Fort Worth area; possibly the lower end of the "Moderate" range in parts of the El Paso, Lubbock, and Midland-Odessa areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of Houston area, with highest concentrations in the afternoon and early evening.

Light to moderate amounts of smoke from ongoing widespread wildfire activity across the Western U.S. may continue over the northern half of the state generally along and north of a line from Presidio to Galveston, with heavier amounts possibly beginning to filter into the Panhandle through Northeast Texas. The majority of the smoke will likely remain aloft, but enough could reach the surface for the daily PM2.5 AQI to reach the middle to upper end of the "Moderate" range in parts of the Amarillo, Dallas-Fort Worth, Lubbock, and Tyler-Longview areas; the lower to middle end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, El Paso, Midland-Odessa, and Waco-Killeen areas; possibly the lower end of the "Moderate" range in parts of the Houston area; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Big Bend, San Antonio, and Victoria areas.

Otherwise and elsewhere across South and Southwest Texas, moderate winds, heavy cloud cover with precipitation, and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.

Light to moderate winds, warm temperatures, abundant afternoon sunshine, and/or increased incoming background levels could be enough for ozone to reach the lower to middle end of the "Moderate" range in parts of the Dallas-Fort Worth, El Paso, and Midland-Odessa areas and possibly the lower end of the "Moderate" range in parts of the Lubbock area, with highest concentrations in the afternoon and early evening.

Moderate amounts of smoke from ongoing widespread wildfire activity across the Western U.S. may continue to spread over much of the state, with heavier amounts possibly continuing over portions of the Panhandle through North Central and Northeast Texas. The majority of the smoke will likely remain aloft, but enough could reach the surface for the daily PM2.5 AQI to reach the upper end of the "Moderate" range or possibly higher in parts of the Dallas-Fort Worth area; the middle to upper end of the "Moderate" range in parts of the Amarillo, Austin, Beaumont-Port Arthur, Brownsville-McAllen, Corpus Christi, Houston, Laredo, Lubbock, Midland-Odessa, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas; and the lower to middle end of the "Moderate" range in parts of the Big Bend and El Paso areas.

Light to moderate winds, warm temperatures, abundant afternoon sunshine, and/or increased incoming background levels could be enough for ozone to reach the middle to upper end of the "Moderate" range in parts of the El Paso area; the lower to middle end of the "Moderate" range in parts of the Dallas-Fort Worth area; possibly the lower end of the "Moderate" range in parts of the Lubbock area; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Midland-Odessa area, with highest concentrations in the afternoon and early evening.

Light to moderate amounts of smoke from ongoing widespread wildfire activity across the Western U.S. may continue over much of the state, but may begin to weaken and clear out along and just inland from the Texas coast as a potential tropical storm meanders around the upper western Gulf of Mexico. The majority of the smoke will likely remain aloft, but enough could reach the surface for the daily PM2.5 AQI to reach the middle to upper end of the "Moderate" range in parts of the Dallas-Fort Worth and Lubbock areas; the lower to middle end of the "Moderate" range in parts of the Amarillo, Austin, Big Bend, El Paso, Laredo, Midland-Odessa, San Antonio, Tyler-Longview, and Waco-Killeen areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Beaumont-Port Arthur, Brownsville-McAllen, Corpus Christi, and Victoria areas.

Otherwise and elsewhere along the Texas coast, strong winds, heavy cloud cover with precipitation, and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.

Light amounts of smoke from ongoing widespread wildfire activity across the Western U.S. may continue over western and northern portions of the state, generally along and northeast of a line from Langtry to Texarkana, as a potential tropical system pushes the smoke out of the remaining areas of the state. The majority of the lingering smoke will likely remain aloft, but enough could reach the surface for the daily PM2.5 AQI to reach the lower to middle end of the "Moderate" range in parts of the Amarillo, Big Bend, Lubbock, and Midland-Odessa areas; possibly the lower end of the "Moderate" range in parts of the El Paso area; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Dallas-Fort Worth and Tyler-Longview areas.

Otherwise across North Central and Northeast Texas and elsewhere in the state, moderate to strong winds, milder temperatures, heavy cloud cover with precipitation, and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.

Light winds, warm temperatures, sufficient afternoon sunshine, and/or increased incoming background levels could be enough for ozone to reach the lower to middle end of the "Moderate" range in parts of the El Paso and Midland-Odessa areas, with highest concentrations in the afternoon and early evening.

Light amounts of smoke from ongoing wildfire activity in the Western U.S. may linger over portions of West Texas and the Panhandle as tropical storm activity otherwise weakens and pushes out the smoke over remaining areas of the state. Much of the lingering smoke will remain aloft, but enough could reach the surface for the daily PM2.5 AQI to reach possibly the lower end of the "Moderate" range in parts of the Amarillo area and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the El Paso, Lubbock, and Midland-Odessa areas.

Otherwise and elsewhere in the state, moderate to strong winds, heavy cloud cover with precipitation, and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.

This forecast was last updated at 9:30 AM on Friday, September 18th, and is updated daily on normal TCEQ work days and may also be updated on weekends or holidays when air pollution levels are high. Regardless of our forecast, we always recommend that each individual determine what level of activity they should conduct based on the actual local conditions.
