Today's Texas Air Quality Forecast

As the previously stalled frontal boundary slowly retreats north along and just north of the I-35 corridor as a weak warm front, 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 in the Austin, Dallas-Fort Worth, Laredo, San Antonio, Tyler-Longview, and Waco-Killeen areas and the upper end of the "Good" range in the Beaumont-Port Arthur, Brownsville-McAllen, Bryan-College Station, Corpus Christi, Houston, 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.

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 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.

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 a second weak frontal boundary slowly advances southeastward, 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 Austin, Beaumont-Port Arthur, Bryan-College Station, Dallas-Fort Worth, Houston, Laredo, San Antonio, Tyler-Longview, and Waco-Killeen areas and the upper end of the "Good" range in the Brownsville-McAllen, 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 weak frontal boundary diffuses along the coast of Southeast Texas, persistent 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 Austin, Beaumont-Port Arthur, Bryan-College Station, Dallas-Fort Worth, Houston, Laredo, San Antonio, Tyler-Longview, and Waco-Killeen areas and the upper end of the "Good" range in the Brownsville-McAllen, 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.
