Today's Texas Air Quality Forecast

An Ozone Action Day is in effect today for the Dallas-Fort Worth area. Light winds, warm to hot temperatures, sufficient afternoon sunshine, and/or lingering elevated incoming background levels could be enough for ozone to reach the lower to middle end of the "Unhealthy for Sensitive Groups" range on the west and northwest side of the Dallas-Fort Worth area; the middle to upper end of the "Moderate" range in parts of the El Paso, Midland-Odessa, and Tyler-Longview areas; the lower to middle end of the "Moderate" range in parts of the Amarillo area; possibly the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur and Lubbock areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Bryan-College Station area, with highest concentrations in the afternoon and early evening.

Slight increased urban fine particulate background levels associated with lingering continental haze with contributions from dissipating weak African dust over coastal portions of South and Southeast Texas and light amounts of transported residual smoke from ongoing wildfire activity in the Western U.S. and Canada filtering into the state from the northeast could be enough to raise the daily PM2.5 AQI to the lower to middle end of the "Moderate" range in parts of the Tyler-Longview area; possibly the lower end of the "Moderate" range in parts of the Corpus Christi and Laredo areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Houston area.

Otherwise and elsewhere in the state, increased cloud cover and/or decreased incoming background levels should help keep air quality in the "Good" range in most spots.

An Ozone Action Day will be in effect on Friday for the Dallas-Fort Worth area. Light to moderate winds, hot temperatures, abundant afternoon sunshine, and/or lingering elevated incoming background levels could be enough for ozone to reach the lower to middle end of the "Unhealthy for Sensitive Groups" range on the northwest side of the Dallas-Fort Worth area; the middle to upper end of the "Moderate" range in parts of the El Paso area; and the lower to middle end of the "Moderate" range in parts of the Amarillo, Lubbock, Midland-Odessa, and Tyler-Longview areas, with highest concentrations in the afternoon and early evening.

Light amounts of transported residual smoke from ongoing wildfire activity in the Western U.S. and Canada may continue filtering into the Upper Panhandle and Northeast Texas in patches, possibly raising the daily PM2.5 AQI to the lower to middle end of the "Moderate" range in parts of the Tyler-Longview area and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Amarillo area.

Elsewhere in the state, increased cloud cover and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.

Light to moderate winds, hot temperatures, sufficient afternoon sunshine, and/or lingering elevated incoming background levels could be enough for ozone to reach the upper end of the "Moderate" range or possibly higher in parts of the El Paso area; the middle to upper end of the "Moderate" range in parts of the Midland-Odessa area; the lower to middle end of the "Moderate" range in parts of the Amarillo and Dallas-Fort Worth 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.

Light amounts of transported residual smoke from ongoing wildfire activity in the Western U.S. and Canada may continue filtering into the Upper Panhandle and Northeast Texas in patches, possibly raising the daily PM2.5 AQI to the lower to middle end of the "Moderate" range in parts of the Tyler-Longview area and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Amarillo area.

Elsewhere in the state, moderate winds and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.

If there is enough afternoon sunshine, light to moderate winds, warm to hot temperatures, and/or sufficient elevated 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; and possibly the lower end of the "Moderate" range in parts of the Amarillo, Lubbock, and Midland-Odessa areas, with highest concentrations in the afternoon and early evening.

Light amounts of transported residual smoke from ongoing wildfire activity in the Western U.S. and Canada may continue filtering into the Upper Panhandle and Northeast Texas in patches, possibly raising the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Tyler-Longview area and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Amarillo area.

Elsewhere in the state, moderate winds, increasing cloud cover, and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.
