Today's Texas Air Quality Forecast

Moderate afternoon winds and/or lower incoming background levels are forecast to be enough to keep ozone levels in the "Good" range for the majority of the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, El Paso, Houston, Midland-Odessa, San Antonio, and Waco-Killeen areas.

The small, scattered agricultural burnings and isolated wildfire activities across parts of Louisiana, East and Southeast Texas continue to produce light density residual smoke that will filter over small portions of these regions of Texas, slightly elevating fine particulate background levels at times during the day. Light morning winds and/or patchy morning fog over portions of Northeast Texas, South Central Texas, and Southeast Texas may at times raise urban fine particulate background levels to the "Moderate" range too. Meanwhile, light density smoke aerosols attributed to industrial activities across the Permian Basin may at times elevate fine particulate levels to the "Moderate" range, however these aerosols are not expected to remain elevated throughout the entire day. Additionally, slightly increased relative humidity levels along coastal regions of Texas may continue to promote fine particulate formation and at times raise PM2.5 levels to the "Moderate" range. The overall daily PM2.5 AQI is forecast to net out in the lower end of the "Moderate" range in parts of the Houston area and the "Good" range (possibly with an isolated low "Moderate") for the majority of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Bryan-College Station, Corpus Christi, Dallas-Fort Worth, Laredo, Midland-Odessa, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas.

Slightly elevated urban fine particulate background levels over portions of far West Texas associated with light daytime winds, lower morning vertical mixing heights, along with some light urban pollutant carryover from the previous days may be enough to briefly raise PM10 levels at times to the "Unhealthy for Sensitive Groups" range. The overall daily PM10 AQI, however, is forecast to net out in the middle to upper end of the "Moderate" range in parts of the El Paso area. The daily PM2.5 AQI is forecast to reach the lower to middle of the "Moderate" range in parts of the El Paso area as well.

Moderate afternoon winds and/or lower incoming background levels are forecast to be enough to keep ozone levels in the "Good" range for the majority of the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, El Paso, Houston, Midland-Odessa, San Antonio, and Waco-Killeen areas.

Should the small, scattered agricultural burnings and isolated wildfire activities across parts of Louisiana, East and Southeast Texas continue, light density residual smoke may continue filtering and lingering over small portions of these regions of Texas and slightly elevate fine particulate background levels. Light morning winds and/or patchy morning fog over portions of South Central Texas, Northeast Texas, and Southeast Texas may at times raise urban fine particulate background levels to the "Moderate" range too. Meanwhile, light density smoke aerosols attributed to industrial activities across the Permian Basin may at times elevate fine particulate levels to the "Moderate" range, however these aerosols are not expected to remain elevated throughout the entire day. Additionally, slightly increased relative humidity levels along coastal regions of Texas may continue to promote fine particulate formation and at times raise PM2.5 levels to the "Moderate" range. The overall daily PM2.5 AQI is forecast to net out in the lower end of the "Moderate" range in parts of the Houston area and the "Good" range for the majority of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Bryan-College Station, Corpus Christi, Dallas-Fort Worth, Laredo, Midland-Odessa, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas.

Depending on the amount of on-going small, scattered agricultural burnings and isolated wildfire activities across parts of Louisiana, East and Southeast Texas, light density residual smoke may continue filtering and lingering over small portions of these regions of Texas and slightly elevate fine particulate background levels. Light morning winds and/or patchy morning fog over portions of North Central, South Central, Northeast, and Southeast Texas in addition to along the Rio Grande Valley may at times raise urban fine particulate background levels to the "Moderate" range. Meanwhile, light density smoke aerosols attributed to industrial activities across the Permian Basin may at times elevate fine particulate levels to the "Moderate" range, however these aerosols are not expected to remain elevated throughout the entire day. Additionally, slightly increased relative humidity levels along coastal regions of Texas may continue to promote fine particulate formation and at times raise PM2.5 levels to the "Moderate" range. The overall daily PM2.5 AQI is forecast to reach the lower end of the "Moderate" range in parts of the Brownsville-McAllen and Houston areas and the "Good" range for the majority of the Austin, Beaumont-Port Arthur, Bryan-College Station, Corpus Christi, Dallas-Fort Worth, Laredo, Midland-Odessa, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas.

Slightly elevated urban fine particulate background levels over portions of far West Texas associated with light morning winds, lower morning vertical mixing heights, along with light urban pollutant carryover from the previous days, ahead of a Pacific cold front forecast to move through the region during the afternoon hours, may be enough to keep PM2.5/PM10 levels slightly elevated. Additionally, gusty afternoon and evening winds associated with the cold front may be enough to generate and transport patchy blowing dust across portions of the region. Overall, the daily PM2.5/PM10 AQIs may rise to the middle to upper end of the "Moderate" range in parts of the El Paso area.

Moderate afternoon winds and/or lower incoming background levels are forecast to be enough to keep ozone levels in the "Good" range for the majority of the Austin, Dallas-Fort Worth, El Paso, Houston, Midland-Odessa, San Antonio, and Waco-Killeen areas.

A cold front will move into West Texas Monday but will gradually diffuse as southerly winds ahead of it advect warm, moist air out of the Gulf. Depending on the isolated wildfire activities across parts of Louisiana, East and Southeast Texas, light density residual smoke may continue filtering and lingering over small portions of these regions of Texas and slightly elevate fine particulate background levels. The higher relative humidity in South Texas as well as along the coast could make conditions more conducive for fine particulate formation and occasionally spike PM2.5 levels into the "Moderate" range but increasing afternoon wind speeds will likely provide sufficient pollutant dispersion for most areas. The overall daily PM2.5 AQI is forecast to reach the lower end of the "Moderate" range in parts of the Brownsville-McAllen and Houston areas and the upper end of the "Good" range for the majority of the Austin, Beaumont-Port Arthur, Bryan-College Station, Corpus Christi, Dallas-Fort Worth, Laredo, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas.

Gusty morning winds behind the aforementioned cold front could continue producing areas of patchy blowing dust across far West Texas in addition to any lingering dust kicked up the previous day. Additionally, with wind speeds expected to decrease during the afternoon and evening hours, fine particulate concentrations are anticipated to remain elevated due to lighter winds and limited vertical mixing. Overall, the daily PM2.5/PM10 AQIs may remain in the middle to upper end of the "Moderate" range in parts of the El Paso area.

Moderate afternoon winds and/or lower incoming background levels are forecast to be enough to keep ozone levels in the "Good" range for the majority of the Dallas-Fort Worth, El Paso, and Houston areas.

Depending on the isolated wildfire activities across parts of Louisiana, East and Southeast Texas, light density residual smoke may continue filtering and lingering over small portions of these regions of Texas and slightly elevate fine particulate background levels. Moisture advection will continue as southerly winds persist in the eastern two thirds of Texas and could promote fine particulate formation, but increased vertical mixing due to an incoming trough could temper overall fine particulate concentrations. Lighter winds in Central, North Central, and Northeast Texas could increase urban fine particulates, but the effects will likely remain limited and not sustain elevated PM2.5 levels throughout the entire day. The overall daily PM2.5 AQI is forecast to reach the upper end of the "Good" range for the majority of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Bryan-College Station, Corpus Christi, Dallas-Fort Worth, Houston, Laredo, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas.

Light morning winds and pollutant carryover from the previous day in far West Texas could sustain elevated fine particulate matter, but the incoming trough will increase vertical mixing and dispersion. Overall, the daily PM2.5/PM10 AQIs may net out in the lower end of the "Moderate" range in parts of the El Paso area.
