Today's Texas Air Quality Forecast

Slightly increased morning cloud cover and/or lower incoming background levels are forecast to be enough to keep ozone levels in the "Good" range for the majority of the state.

Elevated relative humidity levels associated with light morning winds is producing patchy morning fog over the eastern two-thirds of the state as well as the Permian Basin and promoting fine particulate formation, slightly raising PM2.5 levels across these regions of Texas. Additionally, small, isolated agricultural burning activities across parts of the eastern two-thirds of the state and the lower Mississippi River Valley are expected to produce very light density residual smoke and contribute slightly towards raising fine particulate matter, mainly for areas immediately downwind of any burning activities. Also, industrial activities across small parts of the Permian Basin may contribute slightly towards elevating PM2.5 levels over this region of the state. Meanwhile, aerosols attributed to emissions from urban and industrial activities as well as light smoke from scattered fire activities across parts of the central Mexico and the Mexican Coastal Plains may continue to be transported northward over small parts of deep South Texas and slightly raise PM2.5 levels. Periodic gusty winds over portions of these regions of the state is forecast to aid in dispersion of the aforementioned aerosols and therefore, the overall daily PM2.5 AQI is forecast to reach the lower end of the "Moderate" range in parts of the Houston, Midland-Odessa, and Tyler-Longview areas and 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, Laredo, San Antonio, Victoria, and Waco-Killeen areas.

Calm daytime winds over far West Texas are forecast to limit dispersion of urban fine particulate aerosols and raise the daily PM2.5/PM10 AQIs to the middle to upper end of the "Moderate" range in parts of the El Paso area.

Slightly increased morning cloud cover and/or lower incoming background levels are forecast to be enough to keep ozone levels in the "Good" range for the majority of the state.

Elevated relative humidity levels attributed to light morning winds may continue to produce patchy morning fog over the eastern two-thirds of the state as well as the Permian Basin and promote fine particulate formation, slightly raising PM2.5 levels across these regions of Texas. Additionally, potentially ongoing small, isolated agricultural burning activities across parts of the eastern two-thirds of the state and the lower Mississippi River Valley is forecast to continue producing very light density residual smoke that may contribute slightly towards raising fine particulate matter, mainly for areas immediately downwind of any burning activities. Also, industrial activities across small parts of the Permian Basin may produce light density smoke/aerosols that may slightly elevate PM2.5 levels over this region of Texas too. Meanwhile, newer model guidance suggests that wind patterns should limit dispersion of light density smoke and/or aerosols from urban and industrial activities as well as scattered fire activities across parts of the central Mexico and the Mexican Coastal Plains over portions of deep South Texas, so these aerosols should not impact PM2.5 levels at all over this region of Texas. Overall, the daily PM2.5 AQI may reach the lower end of the "Moderate" range in parts of the Austin, Brownsville-McAllen, Corpus Christi, Dallas-Fort Worth, Houston, Laredo, San Antonio, Tyler-Longview, and Waco-Killeen areas and the upper end of the "Good" range for the majority of the Beaumont-Port Arthur, Bryan-College Station, Midland-Odessa, and Victoria, areas.

Light daytime winds, limiting pollutant dispersion, some light urban pollutant carryover from the previous day, as well as some potentially very light density residual smoke from small, burning activities in the northern Mexico state of Chihuahua may filter over portions of far West Texas and raise the daily PM2.5/PM10 AQIs to the middle of the "Moderate" range in parts of the El Paso area.

Model guidance suggests that elevated relative humidity levels attributed to light morning winds over the eastern two-thirds of the state as well as the Permian Basin may continue to produce patchy morning fog and promote fine particulate formation, slightly raising PM2.5 levels across these regions of Texas. Additionally, depending on the potentially ongoing small, isolated agricultural burning activities across parts of the eastern two-thirds of the state and the lower Mississippi River Valley, very light density residual smoke may continue to contribute slightly towards raising fine particulate matter, mainly for areas immediately downwind of any burning activities. Also, industrial activities across small parts of the Permian Basin may produce light density smoke/aerosols that may slightly elevate PM2.5 levels over this region of Texas too. Meanwhile, depending on the urban and industrial activities as well as scattered fire activities across parts of the central Mexico and the Mexican Coastal Plains, light density smoke and/or aerosols may begin to filter and expand over portions of deep South Texas and along the lower coastal bend of Texas. Overall, the daily PM2.5 AQI may reach the lower end of the "Moderate" range in parts of the Brownsville-McAllen, Houston, Laredo, San Antonio, Tyler-Longview, and Waco-Killeen 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, Midland-Odessa, Victoria areas.

Depending on the small, burning activities in the northern Mexico state of Chihuahua, light density residual smoke may continue to filter and expand over small portions of far West Texas, slightly raising fine particulate matter. Meanwhile, light daytime winds combined with some light urban pollutant carryover from the previous days may contribute to keep fine particulate pollutants near the ground and raise the daily PM2.5/PM10 AQIs to the middle of the "Moderate" range in parts of the El Paso area.

Model guidance indicates that elevated relative humidity levels attributed to light morning winds over the eastern two-thirds of the state as well as the Permian Basin may continue to produce patchy morning fog and promote fine particulate formation, slightly raising PM2.5 levels across these regions of Texas. Additionally, should small, isolated agricultural burning activities across parts of the eastern two-thirds of the state and the lower Mississippi River Valley continue, very light density residual smoke may linger and contribute to slightly raise fine particulate matter, mainly for areas immediately downwind of any burning activities. Also, industrial activities across small parts of the Permian Basin may produce light density smoke/aerosols that may slightly elevate PM2.5 levels over this region of Texas too. Meanwhile, depending on the urban and industrial activities as well as scattered fire activities across parts of the central Mexico and the Mexican Coastal Plains, light density smoke and/or aerosols may continue to filter and linger over portions of deep South Texas and along the lower coastal bend of Texas.
