Discussion

Tuesday 04/25/2017
Strong afternoon winds will generate and transport areas of blowing dust into parts of West Texas and the Panhandle, where the duration and intensity of the dust may be enough for the overall daily PM10 AQI to reach "Unhealthy" levels in the El Paso area and "Moderate" in the Lubbock and Midland-Odessa areas, with highest concentrations in the afternoon and evening hours.

Lingering background levels may remain high enough for ozone to reach "Moderate" levels in the Beaumont-Port Arthur, Dallas-Fort Worth, Houston, San Antonio, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening. Elevated fine particulate background levels associated with the continental haze may also be high enough for the daily PM2.5 AQI to reach the lower end of the "Moderate" range in the Tyler-Longview area, as well as a few spots in the Beaumont-Port Arthur and Houston areas.

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

Patchy smoke from agricultural and industrial burning in Mexico and Central America will begin to spread into South Texas ahead of an advancing frontal boundary. Smoke levels will drop rapidly late in the day behind the front, 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, and Victoria areas.

Incoming background levels may be high enough for ozone to reach "Moderate" levels 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 an advancing cold 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.

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.

Thursday 04/27/2017 Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or possibly higher in the Houston area, and "Moderate" in the Austin, Dallas-Fort Worth, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

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

Patchy smoke from agricultural and industrial burning in Mexico and Central America may filter back into parts of the Rio Grande Valley of South Texas, where the overall daily PM2.5 AQI may reach the "Moderate" range in parts of the Brownsville-McAllen and Laredo areas. Smoke levels may begin increasing later in the day in other parts of South Texas, spreading into Central Texas, but levels should be low enough overall for the daily PM2.5 AQI to remain in the "Good" range in these areas.

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

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. While there is some uncertainty at this time about the overall coverage and density of the smoke, levels may be high enough to raise the daily PM2.5 AQI to the "Moderate" range generally east of a line from Del Rio to Gainesville.

Strong afternoon winds could once again generate and transport blowing dust into parts of West Texas and the Panhandle, where the overall daily PM10 AQI may reach "Moderate" or possibly higher in the El Paso area and "Moderate" in the Lubbock area, with the PM2.5 AQI expected to reach "Moderate" in these areas as well. The overall daily AQI is expected to remain in the "Good" range in the Amarillo and Midland-Odessa areas.
