Today's Texas Air Quality Forecast

An upper level storm system with an associated frontal boundary currently stalled over the Texas Panhandle and North Texas along with slightly increased fine particulate levels from elevated relative humidity with low-level cloud cover, pockets of fog, and light background urban fine particulate matter carried over from yesterday may cause the daily PM2.5 AQI to reach the lower end of the "Moderate" range in parts of the El Paso area and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts 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 and elsewhere in the state, moderate winds, mild temperatures, and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.

As the frontal boundary slowly retreats north, slightly increased fine particulate levels from elevated relative humidity with low-level cloud cover, patchy fog, in addition to some light background urban fine particulate carryover from the previous days along the boundary may raise PM2.5 levels into the upper end of the "Good" range in 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.

Slightly elevated afternoon and evening winds associated with another frontal boundary approaching from the north could generate and transport patchy blowing dust into and through portions of the Texas Panhandle, however the intensity and duration of the possible blowing dust is not expected to be enough to raise the daily PM10 AQI beyond the "Good" range throughout the Amarillo and Lubbock areas.

Fine urban particulate levels owing to limited dispersion from light winds and pockets of morning fog could increase the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the El Paso area.

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

Depending on precipitation associated with the aforementioned frontal boundary as it possibly stalls near the I-35 corridor, slightly elevated fine particulate levels associated with increased relative humidity, light winds, areas of patchy fog, and light carry over of particulate matter from the previous day may raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Dallas-Fort Worth and Tyler-Longview areas.

Very light amounts of smoke from seasonal fires across the Southeast U.S. may filter briefly into the Texas coastal areas, which may raise the daily PM2.5 AQI to the lower end of the "Moderate" range in the Brownsville-McAllen and Houston areas. Elsewhere along the coast, the daily PM2.5 AQI is not expected to exceed the upper end of the "Good" range, which includes the Beaumont-Port Arthur, Corpus Christi, and Victoria areas.

Fine urban particulate levels owing to limited dispersion from light winds could increase the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the El Paso area.

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

As the second stalled frontal boundary slowly retreats north, depending on scattered showers, slightly increased fine particulate levels from elevated relative humidity with low-level cloud cover, patchy fog, in addition to some light background urban fine particulate carryover from the previous days may raise PM2.5 levels into the lower end of the "Moderate" range for the Dallas-Fort Worth and Tyler-Longview areas and the upper end of the "Good" range in the Austin, Bryan-College Station, Laredo, San Antonio, and Waco-Killeen areas.

The very light amounts of smoke from seasonal fires across the Southeast U.S. may continue to expand and filter briefly into the Texas coastal areas, which may raise the daily PM2.5 AQI to the lower end of the "Moderate" range in the Brownsville-McAllen and Houston areas. Elsewhere along the coast, the daily PM2.5 AQI is not expected to exceed the upper end of the "Good" range, which includes the Beaumont-Port Arthur, Corpus Christi, and Victoria areas.

Fine urban particulate levels owing to limited dispersion from light winds and pockets of morning fog could increase the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the El Paso area.

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