Today's Texas Air Quality Forecast

Light winds, warm temperatures, 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 area, with the highest concentrations in the afternoon and early evening.

Most of the smoke attributed to wildfires in the Canadian Northwest Territories, central and southern Ontario, and central Saskatchewan as well as Manitoba that may be over the state will be very light in density and remain aloft. Newer satellite and model guidance suggests the burning activities across southern Mexico and Cuba are expected to continue to produce residual smoke while the very light density plumes may filter mainly over portions of deep South Texas and should also remain mostly aloft as well. Meanwhile, the plume of Saharan dust that is lingering over the entire state is beginning to weak end disperse, however a slightly denser plume of Saharan dust is forecast to arrive along coastal regions of Texas and move inland over the southern half of Texas. Light morning winds and/or elevated relative humidity levels are forecast to remain over the eastern two-thirds of the state as well as the Permian Basin, contributing towards slightly raising urban fine particulate matter as well. The overall daily PM2.5 AQI may rise to the middle of the "Moderate" range in parts of the Brownsville-McAllen, Corpus Christi, and Houston areas; the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Bryan-College Station, Dallas-Fort Worth, Laredo, Midland-Odessa, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas; and the upper end of the "Good" range in parts of the Amarillo, Big Bend, and Lubbock areas. New lower morning concentrations suggest that the daily PM10 AQI may only rise to the lower end of the "Moderate" range in parts of the Brownsville-McAllen area and the upper end of the "Good" range in parts of the Austin, Beaumont-Port Arthur, Corpus Christi, Dallas-Fort Worth, Houston, and San Antonio areas as well.

Slightly elevated urban fine particulate levels over far West Texas associated with light daytime winds, some very light density residual smoke from wildfires in Colorado, possibly very light fine particulates attributed to Saharan dust, and/or patchy blowing dust attributed to gusty outflows from local thunderstorms could at times raise PM2.5/PM10 levels to the "Moderate" range, however should only raise the daily PM2.5/PM10 AQIs to the upper end of the "Good" range for most of the region, which includes the El Paso area.

Light winds, warm temperatures, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the lower to middle of the "Moderate" range in parts of the El Paso area and the upper end of the "Good" range in parts of the Amarillo area, with the highest concentrations in the afternoon and early evening.

Very little light density residual smoke associated with the smoke from the wildfires in the Canadian Northwest Territories, central and southern Ontario, and central Saskatchewan as well as Manitoba should remain over the state and will remain mostly aloft. Should the burning activities across southern Mexico and Cuba continue, very light density residual smoke may continue to filter and linger mainly over deep South Texas and should remain mostly aloft too. Meanwhile, the plume of Saharan dust is forecast to filter and expand over most of the state, with the exception of far West Texas. Light morning winds and/or elevated relative humidity levels are forecast to remain over the eastern two-thirds of the state as well as the Permian Basin, contributing towards slightly raising urban fine particulate matter as well. The overall daily PM2.5 AQI may rise to the middle of the "Moderate" range in parts of the Brownsville-McAllen, Corpus Christi, Houston, Laredo, San Antonio, and Victoria areas; the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Bryan-College Station, Dallas-Fort Worth, Lubbock, Midland-Odessa, Tyler-Longview, and Waco-Killeen areas; and the upper end of the "Good" range in parts of the Amarillo and Big Bend areas. The daily PM10 AQI could reach the middle of the "Moderate" range in parts of the Brownsville-McAllen, Corpus Christi, and Houston areas and the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, and San Antonio areas as well.

Slightly elevated urban fine particulate levels over far West Texas associated with light daytime winds, limiting local dispersion of pollutants, some very light density residual smoke from wildfires in Colorado, and/or patchy blowing dust associated with gusty outflows from local thunderstorms may be enough to at times raise PM2.5/PM10 levels to the "Moderate" range, however the daily PM2.5/PM10 AQIs are forecast to remain in the upper end of the "Good" range for most of the region, which includes the El Paso area.

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

Model guidance indicates that most of the residual smoke associated with the smoke from the wildfires in the Canadian Northwest Territories, central and southern Ontario, and central Saskatchewan as well as Manitoba that may be over Texas will be very light in density and should remain mostly aloft. Depending on the burning activities across southern Mexico and Cuba continue, very light density residual smoke may continue to filter and linger over deep South Texas, however, should remain mostly aloft as well. Meanwhile, the plume of Saharan dust is forecast to continue lingering over most of the state, with the exception of far West Texas. Light morning winds and/or elevated relative humidity levels are forecast to remain over the eastern two-thirds of the state as well as the Permian Basin, contributing towards slightly raising urban fine particulate matter as well. The overall daily PM2.5 AQI may rise to the middle of the "Moderate" range in parts of the Beaumont-Port Arthur, Brownsville-McAllen, Bryan-College Station, Corpus Christi, Houston, Laredo, San Antonio, and Victoria areas; the lower end of the "Moderate" range in parts of the Austin, Dallas-Fort Worth, Midland-Odessa, Tyler-Longview, and Waco-Killeen areas; and the upper end of the "Good" range in parts of the Amarillo, Big Bend, and Lubbock, areas. The daily PM10 AQI could reach the lower end of the "Moderate" range in parts of the Brownsville-McAllen, Corpus Christi, and Houston areas and the upper end of the "Good" range in parts of the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, and San Antonio areas as well.

Slightly elevated urban fine particulate levels over far West Texas associated with light daytime winds, limiting dispersion, may be enough to at times raise PM2.5/PM10 levels to the "Moderate" range, however the daily PM2.5/PM10 AQIs are forecast to remain in the upper end of the "Good" range for most of the region, which includes the El Paso area.

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