Forecast Discussion

Tuesday 08/20/2019

Light to moderate winds, warm to hot temperatures, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the upper end of the "Moderate" range or possibly higher on the north and northwest side of the Dallas-Fort Worth area and in parts of the El Paso area; the middle to upper end of the "Moderate" range in parts of the Lubbock area; the lower to middle end of the "Moderate" range in parts of the Midland-Odessa area; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Amarillo area, with the highest concentrations in the afternoon and early evening.

African dust is expected to strengthen across South Texas while spreading northward inland and along the coast to reach portions of Southwest, Central, and East Texas, possibly approaching the Permian Basin and Big Bend region by day's end. Additionally, light amounts of patchy residual smoke associated with lingering continental haze may slightly increase fine particulate background levels in parts of East and Southeast Texas as well. Overall, depending on the movement and intensity of the dust (combined with the patchy light smoke/haze in East/Southeast Texas), the daily PM2.5 AQI is forecast to reach the middle to upper end of the "Moderate" range in parts of the Brownsville-McAllen, Corpus Christi, Houston, Laredo, and Victoria areas; the lower to middle end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, San Antonio, and Tyler-Longview areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Big Bend and Midland-Odessa areas.

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

Light to moderate winds, warm to hot temperatures, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the upper end of the "Moderate" range or possibly higher on the north and northwest side of the Dallas-Fort Worth area and in parts of the El Paso area; the middle to upper end of the "Moderate" range in parts of the Midland-Odessa area; and the lower to middle end of the "Moderate" range in parts of the Houston and Lubbock areas, with the highest concentrations in the afternoon and early evening.

Patchy and slightly weakening African dust will spread to cover much of the state (with the exception of far West Texas and the northern Panhandle) at varying intensities, with the heaviest dust remaining along and east of a line from Del Rio to Temple to Jasper. Additionally, light amounts of patchy residual smoke associated with lingering continental haze may slightly increase fine particulate background levels in parts of East and Southeast Texas as well. Overall, depending on the intensity and coverage of the dust (combined with the patchy light smoke/haze in East/Southeast Texas), the daily PM2.5 AQI is forecast to reach the middle to upper end of the "Moderate" range in parts of the Brownsville-McAllen, Corpus Christi, Houston, and Victoria areas; the lower to middle end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Laredo, Midland-Odessa, San Antonio, and Waco-Killeen areas; possibly the lower end of the "Moderate" range in parts of the Big Bend, Dallas-Fort Worth, and Tyler-Longview areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Lubbock area.

Elsewhere in the northern Texas Panhandle, moderate winds and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.


Thursday 08/22/2019 Outlook

Light to moderate winds, hot temperatures, abundant afternoon sunshine, and elevated incoming background levels could be enough for ozone to reach the upper end of the "Moderate" range or possibly higher in parts of the El Paso area; the middle to upper end of the "Moderate" range in parts of the Dallas-Fort Worth area; and the lower to middle end of the "Moderate" range in parts of the Midland-Odessa area, with the highest concentrations in the afternoon and early evening.

Patchy lingering African dust will persist over much of the state (with the exception of far West Texas) while continuing to gradually weaken. Additionally, light amounts of patchy residual smoke associated with lingering continental haze may slightly increase fine particulate background levels in parts of East Texas as well. Overall, depending on the intensity and coverage of the lingering dust (combined with the patchy light smoke/haze in East Texas), the daily PM2.5 AQI is forecast to reach the lower to middle end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Corpus Christi, Houston, Laredo, Lubbock, San Antonio, Victoria, and Waco-Killeen areas; possibly the lower end of the "Moderate" range in parts of the Big Bend, Dallas-Fort Worth, Midland-Odessa, and Tyler-Longview areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Amarillo area.

Otherwise in the northern Texas Panhandle, moderate winds and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.


Friday 08/23/2019 Outlook

Light to moderate winds, warm to hot temperatures, sufficient afternoon sunshine, and elevated incoming background levels could be enough for ozone to reach the middle to upper end of the "Moderate" range in parts of the El Paso area; the lower to middle end of the "Moderate" range in parts of the Dallas-Fort Worth area; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Midland-Odessa area, with the highest concentrations in the afternoon and early evening.

Very light amounts of patchy weakening African dust will continue to linger mainly in the Texas Panhandle while dissipating elsewhere. Additionally, very light amounts of patchy residual smoke associated with lingering continental haze may slightly increase fine particulate background levels in parts of East Texas as well. However, the intensity of the lingering dust and smoke/haze is not expected to be enough to raise the daily PM2.5 AQI beyond the upper end of the "Good" range across most of the primary impacted areas, including the Amarillo, Lubbock, Beaumont-Port Arthur, and Tyler-Longview areas.

Otherwise and elsewhere in the state, moderate winds, heavy cloud cover with increased precipitation, and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.
