Discussion

Monday 07/24/2017
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" in the Dallas-Fort Worth and El Paso areas, with highest concentrations in the afternoon and early evening.

The fairly intense African dust cloud will continue to spread to cover much of the state except for far West Texas and is expected to raise the daily PM2.5 AQI to "Moderate" or possibly higher levels in the Corpus Christi area, into the otherwise "Moderate" range in most spots along and east of a line from Del Rio to Killeen to Nacogdoches, and into the upper end of the "Good" range with isolated "Moderate" levels elsewhere in all but the El Paso area.

Tuesday 07/25/2017
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" in the Dallas-Fort Worth and El Paso areas, with highest concentrations in the afternoon and early evening.

African dust will continue over most of the state, including lighter amounts arriving in far West Texas, resulting in the overall daily PM2.5 AQI reaching "Moderate" or possibly higher levels in parts of the Corpus Christi area and the "Moderate" range in most remaining spots along and east of a line from Langtry to Abilene to Wichita Falls and the upper end of the "Good" range with isolated "Moderate" levels elsewhere in West Texas and the Panhandle.

Wednesday 07/26/2017 Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" in the El Paso area, with highest concentrations in the afternoon and early evening.

African dust will linger over much of the state, with the more intense dust cloud moving out of South Texas. Overall, the daily PM2.5 AQI is expected to reach "Moderate" levels in the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, Houston, Lubbock, Tyler-Longview, and Victoria areas, and the upper end of the "Good" range elsewhere in South and West Texas and the Panhandle.

Thursday 07/27/2017 Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" in the Dallas-Fort Worth and El Paso areas, with highest concentrations in the afternoon and early evening.

Lingering but diminishing and increasingly patchy African dust will persist over portions of the state, potentially raising the daily PM2.5 AQI into the "Moderate" range primarily in parts of the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, Houston, Tyler-Longview, and Victoria areas.

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