Forecast Discussion

Friday 04/20/2018
Winds may be light enough and/or incoming background levels high enough for ozone to reach "Moderate" in parts of the Beaumont-Port Arthur, El Paso, Houston, and Tyler-Longview areas and the upper end of the "Good" range in the Austin, Dallas-Fort Worth, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

Strong afternoon winds could generate and transport patchy blowing dust into portions of West Texas, possibly raising the daily PM10 AQI to "Moderate" or possibly higher and the daily PM2.5 AQI to "Moderate" in parts of the El Paso area; the limited duration and intensity of the dust along with associated precipitation should keep the AQI in the "Good" range overall in the Midland-Odessa area.

Slightly increased fine particulate background levels associated with continental haze, including contributions from residual light smoke should seasonal burning across the South and Southeastern US continue, could be enough to raise the daily PM2.5 AQI to the lower end of the "Moderate" range primarily in parts of the Corpus Christi area.

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


Saturday 04/21/2018
Incoming background levels may be high enough for ozone to reach "Moderate" in parts of the El Paso area, with highest concentrations in the afternoon and early evening. Slightly elevated urban fine particulate background levels combined with lingering suspended dust and light amounts of smoke from fires in northern Mexico and the Southwestern US could also be enough to raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the El Paso area as well.

Slightly increased fine particulate background levels associated with continental haze, including contributions from residual light smoke should seasonal burning across the South and Southeastern United States continue, could be enough to raise the daily PM2.5 AQI to the lower end of the "Moderate" range primarily in parts of the Beaumont-Port Arthur and Houston areas depending on the duration and intensity of expected precipitation.

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


Sunday 04/22/2018 Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" in parts of the El Paso, Houston, and San Antonio areas, with highest concentrations in the afternoon and early evening.

Light amounts of smoke from agricultural burning in Mexico and Central America is forecast to briefly return to deep South Texas by Sunday, though an arriving cold front will drop fine particulate levels rapidly in the afternoon. Overall, the daily PM2.5 AQI could reach the lower end of the "Moderate" range in parts of the Brownsville-McAllen area.

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


Monday 04/23/2018 Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or possibly higher in parts of the San Antonio area and "Moderate" in parts of the Austin, Beaumont-Port Arthur, Corpus Christi, El Paso, Houston, and Victoria areas, with highest concentrations in the afternoon and early evening.

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


Tuesday 04/24/2018 Extended Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Unhealthy for Sensitive Groups" in parts of the San Antonio area; "Moderate" or possibly higher in parts of the Houston area; and "Moderate" in parts of the Austin, Beaumont-Port Arthur, Corpus Christi, Dallas-Fort Worth, El Paso, and Victoria areas; and the upper end of the "Good" range in the Waco-Killeen area, with highest concentrations in the afternoon and early evening.

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