Forecast Discussion
*”Wednesday 08/07/2019 “*

*An Ozone Action Day is in effect on Wednesday for the Dallas-Fort Worth area.* Winds may be light enough and incoming background levels high enough for ozone to reach “Unhealthy for Sensitive Groups” on the north side of the Dallas-Fort Worth area; the upper end of the “Moderate” range or possibly higher in parts of the El Paso and Midland-Odessa areas; the middle of the “Moderate” range in parts of the Amarillo area; and the lower to middle end of the “Moderate” range in parts of Lubbock and Waco-Killeen areas, with the highest concentrations in the afternoon and early evening.

Should agricultural burning in parts of East Texas and the Ark-La-Tex region continue, light amounts of patchy transported smoke could be enough to raise the daily PM2.5 AQI to the lower end of the “Moderate” range in parts of the Tyler-Longview area.

A weak pulse of African dust is expected to arrive at the Texas coast this afternoon, reaching spots along the coastal bend and south Texas coast. Depending on the timing and intensity of the dust, the daily PM2.5 AQI could reach the lower end of the “Moderate” range in parts of the Brownsville-McAllen and Corpus Christi areas; the upper end of the “Good” range in parts of the Laredo and Victoria areas.

Elsewhere in the state, moderate winds and/or lower incoming background levels should help keep air quality in the “Good” range in most spots.
