Austin & Central Texas Region GOOD PM2.5 PM2.5

TUESDAY 5/21/2019
Warm to hot temperatures, sufficient afternoon sunshine, and elevated incoming background levels could be enough for ozone to reach the lower to middle end of the “Moderate” range in parts of the Midland-Odessa area and possibly the lower end of the “Moderate” range in parts of the Big Bend, El Paso, Lubbock, and San Antonio areas, with highest concentrations in the afternoon and early evening.

Transported smoke from agricultural burning in Mexico and Central America is expected to linger over South and Southeast Texas ahead of an advancing but slowing Pacific front, with the heaviest concentrations remaining over deep South Texas. In addition, as the front moves across the state, it will transport dust generated the previous day as it pushes out the lingering smoke. Overall, depending on the timing of the front, the intensity of the transported dust, and the coverage and intensity of the lingering smoke, the daily PM2.5 AQI is forecast to reach the middle to upper end of the “Moderate” range in parts of the Brownsville-McAllen area; the lower to middle end of the “Moderate” range in parts of the Big Bend, Corpus Christi, Laredo, and Victoria areas; and possibly the lower end of the “Moderate” range in parts of the Houston area.

Strong afternoon winds could generate and transport new areas of blowing dust into far West Texas, possibly raising the daily PM10 AQI to the upper end of the “Moderate” range or possibly higher and the daily PM2.5 AQI to the lower to middle end of the “Moderate” range in parts of the El Paso area, with highest concentrations in the afternoon and evening.

Elsewhere in the state, moderate to strong winds, lingering cloud cover with precipitation, and/or lower incoming background levels should help keep air quality in the “Good” range in most spots.

WEDNESDAY 5/22/2019
Warm to hot temperatures, sufficient 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 Amarillo area; the lower to middle end of the “Moderate” range in parts of the Lubbock and Midland-Odessa areas; and possibly the lower end of the “Moderate” range in parts of the Big Bend and El Paso areas, with highest concentrations in the afternoon and early evening.

Transported smoke from agricultural burning in Mexico and Central America (mixed with very light amounts of early season African dust) is expected to surge rapidly back into and through the eastern two-thirds of the state as the frontal boundary weakens and retreats northward as a warm front, with the heaviest smoke remaining over South Texas. Overall, depending on the timing and progression of the front and the resulting coverage and intensity of the resurgent smoke and weak African dust, the daily PM2.5 AQI is forecast to reach the middle to upper end of the “Moderate” range in parts of the Brownsville-McAllen and Laredo areas; the lower to middle end of the “Moderate” range in parts of the Corpus Christi, San Antonio, Tyler-Longview, and Victoria areas; possibly the lower end of the “Moderate” range in parts of the Austin, Big Bend, and Dallas-Fort Worth areas; and the upper end of the “Good” range (perhaps with an isolated low “Moderate” or two) in parts of the Houston area.

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

THURSDAY 5/23/2019
Light to moderate winds, warm to hot temperatures, abundant afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the lower to middle end of the “Moderate” range in parts of the Amarillo and El Paso areas and possibly the lower end of the “Moderate” range in parts of the Midland-Odessa area, with highest concentrations in the afternoon and early evening.

Transported patchy smoke from agricultural burning in Mexico and Central America (mixed with very light amounts of early season African dust) is expected to continue at varying intensities over portions of the eastern two-thirds of state, with the heaviest smoke remaining over South Texas. Overall, depending on the coverage and intensity of the smoke and weak African dust, the daily PM2.5 AQI is forecast to reach the middle to upper end of the “Moderate” range in parts of the Brownsville-McAllen and Laredo areas; the lower to middle end of the “Moderate” range in parts of the San Antonio and Victoria areas; possibly the lower end of the “Moderate” range in parts of the Austin area; and the upper end of the “Good” range (perhaps with an isolated low “Moderate” or two) in parts of the Corpus Christi, Houston, and Tyler-Longview areas.

Otherwise and elsewhere in the state, moderate to strong winds, increased cloud cover, and/or lower incoming background levels should help keep air quality in the “Good” range in most spots.
