Forecast Discussion

Warm temperatures, abundant afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the upper end of the "Good" range (perhaps with an isolated low "Moderate") in parts of the Austin, Corpus Christi, Dallas-Fort Worth, Houston, and San Antonio areas, with the highest concentrations in the afternoon and early evening.

Depending on the amount of seasonal fire activity across portions of Oklahoma, light residual smoke may expand southward over portions of North Central Texas, slightly raising PM2.5 concentrations at times to the "Moderate" range. Additionally, as a weak cold front moves over South Texas and into the northern Gulf of Mexico, increased fine particulate aerosols in the vicinity of the frontal boundary associated with the light to moderate density residual smoke from the seasonal fire activities across the state yesterday are raising PM2.5 levels across portions of Southeast Texas, Deep South Texas, and the Coastal Plains region. The density of the lingering fine particulate matter is forecast to be enough to raise the daily PM2.5 AQI to the lower to middle end of the "Moderate" range in parts of the Brownsville-McAllen area; to the lower end of the "Moderate" range in parts of the Houston area; and to the upper end of the "Good" range for the majority of the Beaumont-Port Arthur, Corpus Christi, Dallas-Fort Worth, and Victoria areas, with the highest concentrations in the morning.

Otherwise across the state, moderate to strong northerly winds behind the frontal boundary, cool to mild temperatures, and/or lower incoming background levels should help keep air quality in the "Good" range for most areas.

Light winds, warm temperatures, abundant 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 Houston area; the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Bryan-College Station, Dallas-Fort Worth, San Antonio, Tyler-Longview, and Waco-Killeen areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate") for the majority of the Amarillo, Brownsville-McAllen, Corpus Christi, El Paso, Laredo, Lubbock, Midland-Odessa, and Victoria areas, with the highest concentrations in the afternoon and early evening.

As a high-pressure system moves over the state, light morning winds and an overnight temperature inversion will limit atmospheric mixing and dispersion at the surface and slightly raise fine particulate background levels, particularly in more urban locations. The overall daily PM2.5 AQI is forecast to reach the lower end of the "Moderate" range in parts of the El Paso and Houston areas and net out at 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, Tyler-Longview, Victoria, and Waco-Killeen areas.

Otherwise across the Texas Panhandle, Permian Basin, and South Plains, moderate winds, mild temperatures, and/or lower incoming background levels should help keep air quality in the "Good" range for most areas.

Warm temperatures, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the upper end of the "Good" range in parts of the Amarillo, Austin, Beaumont-Port Arthur, Big Bend, Bryan-College Station, Corpus Christi, Dallas-Fort Worth, El Paso, Houston, Laredo, Lubbock, Midland-Odessa, San Antonio, Tyler-Longview, and Waco-Killeen areas, with the highest concentrations in the afternoon and early evening.

Depending on seasonal burning activities across the eastern two-thirds of the state, as the aforementioned high-pressure system moves over the northern Gulf of Mexico and Southeastern U.S., southerly winds may steer light residual smoke over portions of these parts of the state. Additionally, slightly elevated urban fine background levels may slightly elevate PM2.5 concentrations over these same portions of the state as well. Gusty afternoon conditions should help with dispersion of the fine particulate matter associated with any residual smoke and urban aerosols to keep the overall daily PM2.5 AQI in 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.

Otherwise across the state moderate winds, mild temperatures, and/or lower incoming background levels should help keep air quality in the "Good" range for most areas.

Depending on the agricultural burning activities across portions of Mexico and Central America, model guidance suggests that light amounts of residual smoke may arrive over portions of Deep South Texas and along the southern coastal bend of Texas. Additionally, depending on seasonal burning activities across the eastern two-thirds of the state, light residual smoke from these potential sources may contribute PM2.5 aerosols over some parts of these regions of the state as well. Overall, the daily PM2.5 AQI is forecast to reach the lower end of the "Moderate" range in parts of the Brownsville-McAllen area 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.

As a North Pacific low-pressure system moves over the western U.S., gusty winds out ahead of the system over the Texas Panhandle and Far West Texas may generate and transport patchy blowing dust through these portions of the state. The intensity and duration of the possible blowing dust however are not expected to be enough to raise the overall daily PM2.5/PM10 AQIs beyond the "Good" range throughout most of these regions, which includes the Amarillo, El Paso, and Lubbock areas.

Otherwise and elsewhere across the state, moderate winds, mild temperatures, and/or lower incoming background levels should help keep air quality in the "Good" range for most areas.

As the aforementioned North Pacific low-pressure system moves over the desert Southwest U.S., strong daytime winds ahead of the approaching system may generate and transport blowing dust from northern Chihuahua in Mexico, portions of southeast New Mexico, as well as the Texas Panhandle, Far West Texas, and the Permian Basin through these same regions of the state. The PM2.5/PM10 AQIs may spike briefly at times to the upper end of the "Unhealthy for Sensitive Groups" range in parts of Far West Texas and to the upper end of the "Moderate" range to the lower end of the "Unhealthy for Sensitive Groups" range in parts of the Texas Panhandle and the Permian Basin. The density and duration of the blowing dust are forecast to raise the PM2.5 AQI to the upper end of the "Moderate" range in parts of the El Paso area; to the lower end of the "Moderate" range in parts of the Amarillo, Lubbock, and Midland-Odessa areas; and net out at the upper end of the "Good" range for the majority of the Big Bend region. The daily PM10 AQI could reach the lower end of the "Unhealthy for Sensitive Groups" range in parts of the El Paso area as well.

Depending on the agricultural burning activities across portions of Mexico and Central America, model guidance suggests that the possible light residual smoke may continue to filter over Deep South Texas, along the southern coastal bend of Texas, and expand northward over portions of Southwest, South Central, and Southeast Texas. Additionally, depending on seasonal burning activities across the eastern two-thirds of the state, light residual smoke from these potential sources may contribute PM2.5 aerosols over some parts of these regions of the state as well. Overall, the daily PM2.5 AQI is forecast to reach the lower end of the "Moderate" range in parts of the Brownsville-McAllen, Corpus Christi, Laredo, and Victoria areas and the upper end of the "Good" range for the majority of the Austin, Beaumont-Port Arthur, Bryan-College Station, and San Antonio areas.

Otherwise and elsewhere across the state, moderate to strong winds, mild temperatures, and/or lower incoming background levels should help keep air quality in the "Good" range for most areas.
