Forecast Discussion

*”Friday 08/24/2018 “*
*An Ozone Action Day is in effect today for the Houston area.* Winds may be light enough and/or incoming background levels high enough for ozone to reach “Unhealthy for Sensitive Groups” on the north and northwest side of the Houston area; “Moderate” or possibly higher on the north side of the Dallas-Fort Worth area and in parts of the El Paso and Tyler-Longview areas; “Moderate” in parts of the Beaumont-Port Arthur, San Antonio, and Waco-Killeen areas; and the upper end of the “Good” range in the Amarillo, Austin, and Lubbock areas, with the highest concentrations in the afternoon and early evening.

Smoke from ongoing wildfires across the Western United States is expected to continue over the eastern third of the state, impacting spots generally along and east of a line from Wichita Falls to Pearsall to Kingsville, with the strongest smoke remaining over parts of Northeast Texas. Overall due to the smoke, the daily PM2.5 AQI is forecast to reach the middle to upper end of the “Moderate” range in parts of the Tyler-Longview area; the lower to middle end of the “Moderate” range in parts of the Austin, Beaumont-Port Arthur, Corpus Christi, Dallas-Fort Worth, Houston, Victoria, and Waco-Killeen areas; and the upper end of the “Good” range in general with an isolated “Moderate” or two in parts of the Brownsville-McAllen, Laredo, and San Antonio areas.

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