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

Smoke from agricultural burning in Mexico and Central America, mixed with some patchy light African dust, is expected to linger across most of South and Southeast Texas, although precipitation and a frontal boundary becoming stationary across the region will help to reduce levels in some areas. Overall, the daily PM2.5 AQI forecast to reach the "Moderate" range in the Brownsville-McAllen, Corpus Christi, Houston, and Victoria areas.

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

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" in the Dallas-Fort Worth area. Winds may also be light enough and incoming background levels high enough for ozone to reach "Moderate" levels in the El Paso area and, if there is enough afternoon sunshine, in the Houston, Tyler-Longview, and Waco-Killeen areas as well. In each case, highest concentrations are expected in the afternoon and early evening. Increased fine particulate matter background levels associated with the continental haze along with sufficient local add-on could also be enough for the daily PM2.5 AQI to reach the lower end of the "Moderate" range in the Dallas-Fort Worth area as well.

Incoming patchy African dust combined with lingering smoke from agricultural burning in Mexico and Central America is forecast to raise the daily PM2.5 AQI to "Moderate" or possibly higher in the Corpus Christi area and "Moderate" in the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Houston, San Antonio, 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.

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.

Elevated levels of fine particulate matter, mainly comprising of African dust mixed with some light patchy smoke from agricultural burning in Mexico and Central America, are expected to continue across much of the southeastern half of the state and spread into parts of North Central and Northeast Texas. Overall, the daily PM2.5 AQI is forecast to reach the "Moderate" range generally southeast of a line from Eagle Pass to Texarkana.

Elsewhere in the Panhandle and Permian Basin, moderate winds, heavy cloud cover, and/or lower incoming background levels should help to keep air quality in the "Good" range.

Thursday 06/01/2017 Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" levels in the El Paso area, with highest concentrations in the afternoon and early evening.

Lingering but dissipating patchy African dust should continue over parts of the southeastern half of the state, though decreasing fine particulate matter levels helped in part by precipitation should help keep the PM2.5 AQI at the upper end of the "Good" range in most areas. However, the PM2.5 AQIs along the coast, including in the Beaumont-Port Arthur, Corpus Christi, Houston, and Victoria areas, could remain at the lower end of the "Moderate" range overall.

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