Forecast Discussion

*”Tuesday 05/21/2019 “*
Light to moderate winds, warm to hot temperatures, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the middle to upper end of the “Moderate” range in parts of the Big Bend area; the lower to middle end of the “Moderate” range in parts of the Midland-Odessa area; possibly the lower end of the “Moderate” range in parts of the El Paso, Lubbock, and San Antonio areas; and the upper end of the “Good” range (perhaps with an isolated low “Moderate” or two) in parts of the Dallas-Fort Worth and Laredo areas, with highest concentrations in the afternoon and early evening.

Transported smoke from agricultural burning in Mexico and Central America is expected to linger over South and Southeast Texas ahead of an advancing but slowing Pacific front, with the heaviest concentrations remaining over deep South Texas. In addition, as the front moves across the state, it will transport dust generated the previous day as it pushes out the lingering smoke. Finally, very light patches of early season African dust are continuing along the lower Texas coast. Overall, depending on the timing of the front, the intensity of the transported blowing and African dust, and the coverage and intensity of the lingering smoke, the daily PM2.5 AQI is forecast to reach the upper end of the “Moderate” range or possibly higher in parts of the Brownsville-McAllen area; the lower to middle end of the “Moderate” range in parts of the Corpus Christi, Laredo, and San Antonio areas; possibly the lower end of the “Moderate” range in parts of the Dallas-Fort Worth, Houston, and Victoria areas; and the upper end of the “Good” range (perhaps with an isolated low “Moderate” or two) in parts of the Austin, Beaumont-Port Arthur, Big Bend, Tyler-Longview, and Waco-Killeen areas.

Strong afternoon winds could generate and transport blowing dust into portions of the northern Panhandle, possibly raising the daily PM10 AQI to the lower to middle end of the “Moderate” range and the daily PM2.5 AQI to the upper end of the “Good” range (perhaps with an isolated low “Moderate” or two) in parts of the Amarillo area, with highest concentrations in the afternoon and evening.

Otherwise in parts of Central and East Texas, moderate to strong winds, lingering cloud cover with precipitation, and/or lower incoming background levels should help keep air quality in the “Good” range in most spots.
