Discussion

Wednesday 07/26/2017
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or possibly higher on the east and northeast side of the El Paso area and "Moderate" in the Dallas-Fort Worth area, with highest concentrations in the afternoon and early evening.

Dissipating and increasingly patchy African dust will linger over parts of the state, with decreasing fine particulate levels from south to north as the dust moves out of the state. However, the daily PM2.5 AQI could still reach the lower end of the "Moderate" range for the day in parts of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Dallas-Fort Worth, Houston, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas, and the upper end of the "Good" range with isolated "Moderate" levels elsewhere in South Texas, the Permian Basin, and the Panhandle.

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

Very light amounts of residual returning patchy African dust may recirculate over parts of Southeast Texas, potentially raising the daily PM2.5 AQI to the lower end of the "Moderate" range primarily in parts of the Victoria area and the upper end of the "Good" range with isolated "Moderate" levels elsewhere in the region mainly along the coast.

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

Friday 07/28/2017 Outlook
If there is enough afternoon sunshine, winds may be light enough and incoming background levels high enough for ozone to reach "Unhealthy for Sensitive Groups" on the east and northeast side of the Houston area; "Moderate" or possibly higher on the north and northwest side of the San Antonio area; and "Moderate" in the Dallas-Fort Worth and El Paso areas, with highest concentrations in the afternoon and early evening.

Very light amounts of residual returning patchy African dust may recirculate over parts of South and Southeast Texas, potentially raising the daily PM2.5 AQI into the lower end of the "Moderate" range primarily in parts of the Beaumont-Port Arthur, Brownsville-McAllen, Corpus Christi, Houston, Laredo, and Victoria areas. Additionally, slightly increased urban fine particulate background levels, perhaps with limited contributions from lingering light African dust as well, could also raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Dallas-Fort Worth area as well.

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