Today's Texas Air Quality Forecast

Light winds, warm temperatures, sufficient afternoon sunshine, and/or slightly 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.

A weak high-pressure system is moving overhead that will produce light east to southeast daytime winds over the eastern two-thirds of Texas while a cooler airmass and moisture produces scattered showers across most of the eastern two-thirds of the state. While slightly elevated relative humidity levels and/or urban fine particulates associated with the light winds may slightly raise PM2.5 levels over the more populated areas for these regions of Texas, the precipitation should help was out most of the fine particulates and better afternoon vertical mixing should help disperse the urban fine particulates. Overall, the daily PM2.5 AQI could reach the lower end of the "Moderate" range in parts of the Dallas-Fort Worth area and should remain in the "Good" range for the majority of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Bryan-College Station, Corpus Christi, Houston, Laredo, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas.

Light daytime winds may limit pollutant dispersion over the more populated areas of far West Texas, slightly raising PM2.5/PM10 levels at times. The overall daily PM2.5/PM10 AQIs may rise to the lower end of the "Moderate" range in parts of the El Paso area.

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

Light morning winds and/or slightly rising relative humidity levels over the eastern two-thirds of the state may continue to slightly raise fine particulate matter, primarily over the more populated areas. Additionally, burning, gas flaring, and industrial activities across portions of southern and central Mexico as well as the Bay of Campeche may produce light density residual smoke that could start filtering over parts of deep South Texas. While the scattered rain showers are forecast to continue over the eastern two-thirds of the state and should help washout some of the fine particulates, the overall daily PM2.5 AQI may rise to the lower end of the "Moderate" range in parts of the Brownsville-McAllen and Corpus Christi areas and is expected to remain in the "Good" range for the majority of the Austin, Beaumont-Port Arthur, Bryan-College Station, Dallas-Fort Worth, Houston, Laredo, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas.

Light daytime winds may again limit pollutant dispersion over the more populated areas of far West Texas, slightly raising PM2.5/PM10 levels. The overall daily PM2.5/PM10 AQIs are forecast to remain in the lower end of the "Moderate" range in parts of the El Paso area.

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

A combination of light morning winds and elevated relative humidity levels over the majority of the state with the exception of far West Texas could continue to raise fine particulate matter, especially over the more populated areas. Additionally, depending on the amount of burning, gas flaring, and industrial activities across portions of southern and central Mexico as well as the Bay of Campeche, light density residual smoke may continue filtering over deep South Texas and the Coastal Plains. While the rain showers are forecast to weaken and decrease over the eastern two-thirds of the state, the overall daily PM2.5 AQI may reach the lower end of the "Moderate" range in parts of the Brownsville-McAllen, Bryan-College Station, Corpus Christi, Houston, Laredo, San Antonio, and Victoria areas and is expected to remain in the "Good" range for the majority of the Austin, Beaumont-Port Arthur, Big Bend, Dallas-Fort Worth, Midland-Odessa, Tyler-Longview, and Waco-Killeen areas.

Slightly gusty afternoon and evening winds across portions of far West Texas and the northern Mexico state of Chihuahua could generate and transport light density patchy blowing dust into and through parts of the region. The intensity and duration of the possible blowing dust may be enough to raise the daily PM2.5/PM10 AQIs to the lower to middle of the "Moderate" range in parts of the region, which include the El Paso area.

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

Light morning winds combined with elevated relative humidity levels over the eastern two-thirds of the state could continue to elevate fine particulate matter, especially over the more populated areas. Additionally, should the burning, gas flaring, and industrial activities across portions of southern and central Mexico as well as the Bay of Campeche continue, light density residual smoke may continue lingering and filtering over deep South Texas, the Coastal Plains, the lower Rio Grande Valley, and parts of Southeast Texas. The overall daily PM2.5 AQI may reach the lower end of the "Moderate" range in parts 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.

Slightly elevated afternoon and evening winds across portions of far West Texas and the Permian Basin, associated with the development of a dryline frontal boundary, could generate and transport patchy blowing dust into and through parts of the regions. The intensity and duration of the possible blowing dust may be enough to raise the daily PM2.5 AQI to the lower to middle of the "Moderate" range in parts of the El Paso area and to the upper end of the "Good" range in parts of the Midland-Odessa area. The daily PM10 AQI could reach the lower to middle of the "Moderate" range in parts of the El Paso area as well.
