Discussion

Friday 05/26/2017
If there is enough afternoon sunshine, lingering background levels may be high enough for ozone to reach the low end of the "Moderate" range on the north side of the Dallas-Fort Worth area, with highest concentrations in the afternoon and early evening.

Patchy smoke from agricultural burning in Mexico and Central America has spread across parts of South, Central, and Southeast Texas, and lingering continental haze has also slightly raised fine particulate levels across parts of North and East Texas. Overall, the daily PM2.5 AQI is forecast to reach the "Moderate" range today in most areas generally east of a line from Del Rio to Waco to Gainesville.

Strong afternoon winds are forecast to generate and transport patchy blowing dust into parts of West Texas and the Panhandle, including the El Paso area, where the intensity and duration of the dust may be enough to raise the overall daily PM10 and PM2.5 AQI into the "Moderate" range. Dust may also raise PM10 levels at times in the Lubbock area, but the overall daily PM10 AQI is forecast to remain in the "Good" range there. In all cases, highest dust concentrations are expected during the afternoon and evening.

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

Smoke from agricultural burning in Mexico and Central America is forecast to continue spreading across much of the southeastern two-thirds of the state, possibly mixing with some patchy light African dust moving later in the day into parts of South and Southeast Texas. Overall, the daily PM2.5 AQI is forecast to reach "Moderate" or possibly higher in parts of the Brownsville-McAllen, Corpus Christi, and Victoria areas; and "Moderate" otherwise in most areas east of a line from Sanderson to Wichita Falls.

The combination of light amounts of lingering dust, patchy light smoke from fires in Central Mexico, and local fine particulate add-on may be enough to raise the PM2.5 AQI to the low end of the "Moderate" range in the El Paso area. In addition, incoming background levels may be high enough for ozone to reach "Moderate" in the El Paso area as well, with highest concentrations in the afternoon and early evening.

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

Sunday 05/28/2017 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.

Elevated levels of fine particulate matter, mainly comprising smoke from agricultural burning in Mexico and Central America mixed with some patchy light African dust, are expected to continue across much of the southeastern half of the state, but levels are expected to drop behind a frontal boundary as it moves southward into the heart of the state. 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 state, moderate winds, heavy cloud cover, and/or lower incoming background levels should help to keep air quality in the "Good" range.

Monday 05/29/2017 Outlook
If there is enough afternoon sunshine, winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" 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 parts of South 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, 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.

Tuesday 05/30/2017 Extended Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or, if there is enough afternoon sunshine, possibly higher in the Dallas-Fort Worth area. If there is enough afternoon sunshine, winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" in the Houston and Waco-Killeen areas as well. In all cases, highest concentrations are expected in the afternoon and early evening.

Lingering smoke from agricultural burning in Mexico and Central America, perhaps mixed with some patchy light African dust, is forecast to raise the daily PM2.5 AQI forecast into the "Moderate" range in the Brownsville-McAllen, Corpus Christi, and Victoria areas. In addition, local fine particulate add-on due to urban air stagnation, possibly combined with patchy light Afrtican dust, may raise the daily PM2.5 AQI to "Moderate" in the Houston area as well.

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