Discussion

Wednesday 04/26/2017
Smoke from agricultural and industrial burning in Mexico and Central America has spread into parts of South, Southeast, and Central Texas this morning. Smoke levels will drop rapidly from west to east today behind an advancing frontal boundary, but may be high enough overall for the daily PM2.5 AQI to reach the "Moderate" range in parts of the Brownsville-McAllen, Corpus Christi, Houston, and Victoria areas.

Incoming background levels may be high enough for ozone to reach "Moderate" in the El Paso area, with highest concentrations in the afternoon and early evening. Lingering fine particulate matter may also raise El Paso's daily PM2.5 AQI into the "Moderate" range as well.

Dust raised on Tuesday across West Texas will likely spread eastward across the state behind the advancing front, but dust concentrations are not expected to be high enough to raise the overall daily PM10 or PM2.5 AQI out of the "Good" range in areas not already affected by smoke.

Elsewhere in the state, moderate to strong winds, heavy cloud cover with precipitation, 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" or possibly higher in northern and northwestern sections of the Houston area, and "Moderate" in the Beaumont-Port Arthur, Tyler-Longview, and Victoria areas. In addition, while increasing afternoon winds will limit local add-on, incoming background levels may still be high enough for ozone to reach the lower end of the "Moderate" range in parts of the Austin, San Antonio, and Waco-Killeen areas. Ozone is forecast to remain generally in the upper part of the "Good" range in the Dallas-Fort Worth area, although a few isolated areas mainly north of the Metroplex could reach the low end of the "Moderate" range. In all cases, highest concentrations are expected in the afternoon and early evening.

Strong afternoon winds are forecast to again generate and transport blowing dust into parts of West Texas and the Panhandle. Dust duration and intensity may be great enough for the overall daily PM10 and PM2.5 AQIs to reach "Moderate" or possibly higher in the El Paso area. In the Panhandle, while dust concentrations may be elevated at times, overall levels are not expected to be high enough to raise the overall PM10 and PM2.5 AQI beyond the upper part of the "Good" range in the Amarillo, Lubbock, or Midland areas.

Smoke from agricultural and industrial burning in Mexico and Central America is forecast to spread back into parts of South and Central Texas, where the overall daily PM2.5 AQI may reach the "Moderate" range in parts of the Brownsville-McAllen, Corpus Christi, and Laredo areas, perhaps also reaching the lower end of the "Moderate" range in the San Antonio area. Smoke levels in all areas will likely be highest in the evening hours.

Friday 04/28/2017 Outlook
Smoke from agricultural and industrial burning in Mexico and Central America is forecast to spread rapidly north and northeastward across much of the eastern two-thirds of the state. Smoke levels may be high enough to raise the daily PM2.5 AQI into the "Moderate" range generally east of a line from Del Rio to Gainesville.

Strong afternoon winds are once again expected to generate and transport blowing dust into parts of West Texas. Dust duration and intensity may be great enough for the overall daily PM10 and PM2.5 AQIs to reach "Moderate" or possibly higher in the El Paso area. Brief periods of dust may also occur in the Panhandle, but the overall PM10 and PM2.5 AQI are not expected to exceed the "Good" range in the Amarillo, Lubbock, or Midland areas.

Saturday 04/29/2017 Outlook
Smoke from agricultural and industrial burning in Mexico and Central America will continue across much of the eastern two-thirds of the state, although an advancing frontal boundary and accompanying precipitation will tend to reduce smoke levels, particularly across North, Central, and East Texas. Overall, the daily PM2.5 AQI may reach the "Moderate" range generally south of an Eagle Pass-Austin-Baytown line.

Strong afternoon winds may once again generate and transport blowing dust into parts of West Texas, although the wind direction is forecast to be less favorable for dust transport. Overall, the overall daily PM10 and PM2.5 AQI may reach "Moderate" in the El Paso area. 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 to strong winds, heavy cloud cover with precipitation, and/or lower incoming background levels should help to keep air quality in the "Good" range.
