Today's Texas Air Quality Forecast

Warm to hot temperatures, light winds, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the middle of the "Moderate" range in parts of the El Paso area; the lower end of the "Moderate" range in parts of the Midland-Odessa area; and the upper end of the "Good" range in parts of the Amarillo, Dallas-Fort Worth, Houston, and Lubbock areas, with the highest concentrations in the afternoon and early evening.

A weakening and dispersing plume of Saharan dust is lingering over the majority of the state, with the exception of the Texas Panhandle and far West Texas. Meanwhile, very light density residual smoke from fires in northern California and the Madre fire in southern California combined with some from the wildfire activities across central Alaska and the Canadian central provinces of Yukon, Northwest Territories, Alberta, Saskatchewan, and Manitoba are filtering and lingering over the Texas Panhandle, South Plains, Permian Basin, far West Texas as well as East Texas, North Central Texas, Southeast Texas, and along the coastal bend of Texas, however most of these aerosols should remain aloft. Additionally, slightly elevated relative humidity levels and light daytime winds will occur across the majority of the state and are expected to contribute towards raising fine particulate matter too. Overall, the daily PM2.5 AQI is forecast to reach the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Big Bend, Brownsville-McAllen, Bryan-College Station, Corpus Christi, Dallas-Fort Worth, Houston, Laredo, Midland-Odessa, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas and the upper end of the "Good" range for the majority of the Amarillo, El Paso, and Lubbock areas. The daily PM10 AQI could reach the upper end of the "Good" range in parts of the Austin, Brownsville-McAllen, Corpus Christi, Dallas-Fort Worth, Houston, and San Antonio areas as well.

Warm to hot temperatures, light winds, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the lower end of the "Moderate" range in parts of the El Paso and Midland-Odessa areas and the upper end of the "Good" range in parts of the Amarillo, Dallas-Fort Worth, and Lubbock areas, with the highest concentrations in the afternoon and early evening.

Very little of the aerosols from the light density plume of Saharan dust are forecast to remain over the state. Meanwhile, very light density residual smoke attributed to the fires in California, northern and southern New Mexico, along with the wildfire activities across central Alaska and the Canadian central provinces of Yukon, Northwest Territories, Alberta, Saskatchewan, and Manitoba are forecast to linger over most of the state, however the aerosols should remain aloft. Additionally, slightly elevated relative humidity levels and light daytime winds are forecast across the majority of the state and should contribute towards raising fine particulate matter too. Overall, the daily PM2.5 AQI is forecast to reach the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Big Bend, Brownsville-McAllen, Corpus Christi, Dallas-Fort Worth, Houston, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas and the upper end of the "Good" range for the majority of the Amarillo, Bryan-College Station, Laredo, Lubbock, and Midland-Odessa areas. The daily PM10 AQI could reach the upper end of the "Good" range in parts of the Brownsville-McAllen, Corpus Christi, Dallas-Fort Worth, and Houston areas as well.

Fine urban particulate levels owing to light daytime winds and very light density residual smoke may raise the daily PM2.5 AQI to the upper end of the "Good" range (perhaps with an isolated low "Moderate") in parts of the El Paso area.

Warm to hot temperatures, light winds, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the lower end of the "Moderate" range in parts of the Dallas-Fort Worth area and the upper end of the "Good" range in parts of the Amarillo, El Paso, Lubbock, and Midland-Odessa areas.

Model guidance suggests that very light density residual smoke associated with potentially on-going fire activities in California, New Mexico, and across central Alaska as well as Canada may continue to linger over most of the state, however the aerosols should continue to remain aloft. Meanwhile, the leading edge of another moderately dense plume of Saharan dust may arrive over deep South Texas and begin moving over the lower coastal bend of Texas later on in the evening. Additionally, slightly elevated relative humidity levels and light daytime winds are forecast to persist across the majority of the state and should contribute towards raising fine particulate matter too. Overall, the daily PM2.5 AQI is forecast to reach the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Corpus Christi, Dallas-Fort Worth, Houston, Laredo, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas and the upper end of the "Good" range for the majority of the Amarillo, Big Bend, Bryan-College Station, Lubbock, and Midland-Odessa areas. The daily PM10 AQI could reach the upper end of the "Good" range in parts of the Brownsville-McAllen, Corpus Christi, and Houston areas as well.

Slightly elevated urban fine particulate background levels over portions of far West Texas associated with light winds along with potentially lingering very light density residual smoke could maintain the daily PM2.5 AQI at the upper end of the "Good" range (perhaps with an isolated low "Moderate") in parts of the El Paso area.

Warm to hot temperatures, light winds, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the lower end of the "Moderate" range in parts of the Dallas-Fort Worth and El Paso areas and the upper end of the "Good" range in parts of the Amarillo, Lubbock, and Midland-Odessa areas.

Model guidance suggests that the very light density residual smoke associated with potentially on-going fire activities in California, New Mexico, and across central Alaska as well as Canada may continue to linger mainly over the northern half of the state, however the aerosols are expected to remain aloft. Meanwhile, the moderately dense plume of Saharan dust is forecast to move farther inland, possibly reaching as far north as portions of the upper Rio Grande Valley, the Permian Basin, as well as North Central Texas. Additionally, slightly elevated relative humidity levels are forecast to persist across the eastern two-thirds of the state and should contribute towards raising fine particulate matter too. Overall, the daily PM2.5 AQI is forecast to reach the middle of the "Moderate" range in parts of the Austin, Brownsville-McAllen, Corpus Christi, Laredo, San Antonio, and Victoria areas; the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur, Bryan-College Station, Dallas-Fort Worth, Houston, Tyler-Longview, and Waco-Killeen areas; and the upper end of the "Good" range for the majority of the Amarillo, Big Bend, Lubbock, and Midland-Odessa areas. The daily PM10 AQI could reach the lower end of the "Moderate" range in parts of the Brownsville-McAllen and Corpus Christi areas and the upper end of the "Good" range in parts of the Austin, Houston, and San Antonio areas as well.

Light daytime winds and lower morning vertical mixing heights over far West Texas, slightly raising urban aerosols, along with possible light density residual smoke may raise the daily PM2.5/PM10 AQIs to the lower end of the "Moderate" range in parts of the El Paso area.
