Discussion

Friday 04/28/2017
Smoke, mainly from agricultural burning in Mexico and Central America, has spread across much of the eastern two-thirds of the state this morning. Smoke may be heavy at times today, especially in South and Southeast Texas. Overall, the daily PM2.5 AQI is forecast to reach "Moderate" 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 far West Texas, where dust duration and intensity may be great enough for the overall daily PM10 and PM2.5 AQIs to reach "Moderate" in the El Paso area.

In the remainder of West Texas and the Panhandle, moderate winds and lower incoming background levels should keep air quality in the "Good" range.

Smoke, heavy at times, will continue across much of the eastern two-thirds of the state, although an advancing cold front and accompanying precipitation will help to reduce smoke levels in some areas, especially across parts of North and Northeast Texas. Overall, the daily PM2.5 AQI is expected to reach "Moderate" or possibly higher in parts of the Brownsville-McAllen, Corpus Christi, and Laredo areas, and "Moderate" elsewhere generally southeast of line from Del Rio to Texarkana.

Strong afternoon winds may once again generate and transport blowing dust into parts of far West Texas, although the wind direction is forecast to be less favorable for dust transport on Saturday. Overall, the overall daily PM10 and PM2.5 AQI may reach the lower end of the "Moderate" range in the El Paso area. Incoming background levels may be high enough for ozone to reach the lower end of "Moderate" in the El Paso area as well, with highest concentrations in the afternoon and early evening.

In the remainder of West Texas and the Panhandle, moderate to strong winds, cool temperatures, heavy cloud cover with precipitation, and/or lower incoming background levels should help to keep air quality in the "Good" range.

Sunday 04/30/2017 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 evening. Light winds and accompanying urban air stagnation may allow the overall daily PM2.5 AQI to reach "Moderate" in parts of the El Paso area as well, with highest concentrations in the morning and overnight hours.

Lingering smoke from agricultural and industrial burning in Mexico and Central America may cause elevated fine particulate levels during the predawn hours along parts of the Gulf coast and far East Texas, but levels will drop quickly behind an advancing cold front, and the overall daily PM2.5 AQI should net out in the "Good" range in these areas.

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

Monday 05/01/2017 Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Unhealthy for Sensitive Groups" mainly on the north and northeast side of the Houston area; "Moderate" or possibly higher in the Austin, Beaumont-Port Arthur, San Antonio, and Tyler-Longview areas; and "Moderate" in the Brownsville-McAllen, Corpus Christi, Dallas-Fort Worth, El Paso, Laredo, Victoria, and Waco-Killeen areas. In all cases, highest concentrations are expected in the afternoon and early evening.

Light winds and accompanying urban air stagnation may again allow the overall daily PM2.5 AQI to reach "Moderate" in parts of the El Paso area as well, with highest concentrations in the morning and overnight hours.

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

Tuesday 05/02/2017 Extended Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" in the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, Houston, San Antonio, Tyler-Longview, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

Light winds and accompanying urban air stagnation may again allow the overall daily PM2.5 AQI to reach "Moderate" in parts of the El Paso area as well, with highest concentrations during in the morning hours. Lingering background levels could also allow ozone to reach the lower end of the "Moderate" range in the El Paso area as well, with highest concentrations in the morning and overnight.

Smoke, mainly from agricultural burning in Mexico and Central America, is forecast to return to deep South Texas, where the overall daily PM2.5 AQI could reach "Moderate" in the Brownsville-McAllen, Corpus Christi, and Laredo areas.

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