Forecast Discussion

Thursday 04/19/2018
Winds may be light enough and/or incoming background levels high enough for ozone to reach "Moderate" in parts of the Dallas-Fort Worth, El Paso, San Antonio, Tyler-Longview, and Waco-Killeen areas and the upper end of the "Good" range in the Houston and Victoria areas, with highest concentrations in the afternoon and early evening.

Elevated afternoon winds could generate and transport light amounts of patchy blowing dust across portions of West Texas and the South Plains, though the duration and intensity is not expected to be enough to raise the daily PM10 AQI beyond the "Good" range in most of the El Paso, Lubbock, and Midland-Odessa areas. However, slightly elevated urban fine particulate background levels combined with lingering dust and possible light smoke from fires in northern Mexico and the Southwestern US could raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the El Paso area.

Light smoke from continuing wildfires and seasonal burning across the Central US could briefly increase fine particulate levels across portions of the state, though the intensity is not expected to be enough to raise the daily PM2.5 AQI beyond the "Good" range in most spots. Otherwise, moderate to strong winds and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.

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 Waco-Killeen area, with highest concentrations in the afternoon and early evening.

Strong afternoon winds could generate and transport light amounts of patchy blowing dust into portions of West Texas, possibly raising the daily PM10 AQI to "Moderate" in parts of the El Paso 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 and Victoria areas and the upper end of the "Good" range at most elsewhere.

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


Saturday 04/21/2018 Outlook
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 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 04/21/2018 Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" in parts of the El Paso and San Antonio and the upper end of the "Good" range in the Corpus Christi 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.
