Forecast Discussion

Thursday 07/19/2018
Winds may be light enough and/or incoming background levels high enough for ozone to reach "Moderate" or possibly higher in parts of the El Paso area and "Moderate" in parts of the Amarillo, Dallas-Fort Worth, and Lubbock areas, with highest concentrations in the afternoon and early evening.

Another fairly intense pulse of African dust is expected to arrive in South and Southeast Texas along the coast before pushing inland into parts of Central and Southeast Texas, with at least light amounts lingering in patches across the remainder of the state. Overall, the daily PM2.5 AQI is forecast to reach "Moderate" or possibly higher in parts of the Laredo area; the middle to upper end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Corpus Christi, Dallas-Fort Worth, Houston, San Antonio, Victoria, and Waco-Killeen areas; the lower to middle end of the "Moderate" range in parts of the Big Bend, Lubbock, Midland-Odessa, and Tyler-Longview areas; and the upper end of the "Good" range in parts of the Amarillo and El Paso areas. The daily PM10 AQI associated with the dust could also reach the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Corpus Christi, Dallas-Fort Worth, Houston, Laredo, San Antonio, Victoria, and Waco-Killeen areas as well.

Additionally, smoke from isolated fires (particularly those in the southeastern Panhandle and central part of the state) may intermittently and locally increase PM2.5 levels at locations in the vicinity and immediately downwind of the fires, adding to the already elevated particulates associated with African dust.


Friday 07/20/2018
An Ozone Action Day will be in effect on Friday for the Dallas-Fort Worth, El Paso, and Houston areas. Winds may be light enough and/or incoming background levels high enough for ozone to reach "Unhealthy for Sensitive Groups" on the northeast sides of the Dallas-Fort Worth and Houston areas and in parts of the El Paso area; and "Moderate" in parts of the Amarillo and Lubbock areas, with highest concentrations in the afternoon and early evening.

African dust is expected to persist across the entire state, with the heaviest dust forecast to shift further inland into portions of Central, North Central, and East Texas. Overall, the daily PM2.5 AQI is forecast to reach "Moderate" or possibly higher in parts of the Beaumont-Port Arthur area; the middle to upper end of the "Moderate" range in parts of the Austin, Dallas-Fort Worth, San Antonio, Tyler-Longview, and Waco-Killeen areas; the lower to middle end of the "Moderate" range in parts of the Big Bend, Brownsville-McAllen, Corpus Christi, Houston, Laredo, Midland-Odessa, and Victoria areas; and the upper end of the "Good" range in parts of the Amarillo, El Paso, and Lubbock areas. The daily PM10 AQI associated with the dust could also reach the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, San Antonio, Tyler-Longview, and Waco-Killeen areas as well.


Saturday 07/21/2018 Outlook
