Forecast Discussion

Tuesday 06/18/2019
While an Ozone Action Day is not officially in effect, the latest information available this morning indicates that winds may be light enough and incoming background levels high enough for ozone to possibly reach "Unhealthy for Sensitive Groups" on the north and northeast side of the Dallas-Fort Worth area, with highest concentrations in the afternoon and early evening. Additionally, 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 upper end of the "Moderate" range or possibly higher on the northeast side of the Houston area; the middle to upper end of the "Moderate" range in parts of the El Paso and Midland-Odessa areas; the lower to middle end of the "Moderate" range in parts of the Amarillo, Austin, and Lubbock areas; possibly the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur, San Antonio, and Waco-Killeen areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Tyler-Longview area, with highest concentrations in the afternoon and early evening.

Very light amounts of African dust may continue to linger in patches along and just off the Texas coast, possibly increasing fine particulate levels at times, though the intensity and duration of the dust is not expected to be enough to raise the daily PM2.5 AQI beyond the upper end of the "Good" range throughout most of the Beaumont-Port Arthur, Brownsville-McAllen, and Corpus Christi areas.

Otherwise and elsewhere in the state, moderate winds and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.


Wednesday 06/19/2019
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 El Paso and Midland-Odessa areas; the lower to middle end of the "Moderate" range in parts of the Big Bend and Lubbock areas; possibly the lower end of the "Moderate" range in parts of the Amarillo, Austin, Dallas-Fort Worth, Houston, and San Antonio areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Waco-Killeen area, with highest concentrations in the afternoon and early evening.

Light to moderate amounts of African dust may continue to linger just off the Texas coast and could begin moving back into the state, primarily in South Texas. Overall, depending on the movement and intensity of the returning dust, the daily PM2.5 AQI is forecast to reach the middle to upper end of the "Moderate" range in parts of the Brownsville-McAllen and Corpus Christi areas and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Beaumont-Port Arthur and Victoria areas.

Otherwise and elsewhere in the state, moderate winds and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.


Thursday 06/20/2019 Outlook
Light to moderate winds, hot temperatures, abundant afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the upper end of the "Moderate" range or possibly higher in parts of the Lubbock and Midland-Odessa areas; the middle to upper end of the "Moderate" range in parts of the Amarillo and El Paso areas; and the lower to middle end of the "Moderate" range in parts of the Big Bend area, with highest concentrations in the afternoon and early evening.

Light to moderate amounts of returning African dust will continue along the Texas coast while spreading inland primarily into portions of South, South Central, and East Texas, with the heaviest dust arriving in deep South Texas. Overall, depending on the timing, duration, and intensity of the dust, the daily PM2.5 AQI is forecast to reach the middle to upper end of the "Moderate" range in parts of the Brownsville-McAllen area; the lower to middle end of the "Moderate" range in parts of the Corpus Christi and Victoria areas; possibly the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur and Houston areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Laredo, San Antonio, and Tyler-Longview areas.

Otherwise and elsewhere in the state, moderate winds and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.


Friday 06/21/2019 Outlook
Warm to hot temperatures, sufficient afternoon sunshine, and elevated incoming background levels could be enough for ozone to reach the lower to middle end of the "Moderate" range in parts of the Amarillo and El Paso areas; possibly the lower end of the "Moderate" range in parts of the Big Bend area; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Lubbock area, with highest concentrations in the afternoon and early evening.

Light to moderate amounts of African dust will continue spreading inland through Texas on Friday, possibly impacting spots at varying intensities generally along and east of a line from Del Rio to Wichita Falls, with the heaviest dust remaining along the lower Texas coast. Overall, depending on the movement and intensity of the dust, 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 middle to upper end of the "Moderate" range in parts of the Corpus Cristi area; the lower to middle end of the "Moderate" range in parts of the Beaumont-Port Arthur, Dallas-Fort Worth, Houston, Laredo, San Antonio, and Victoria areas; possibly the lower end of the "Moderate" range in parts of the Austin, Tyler-Longview, and Waco-Killeen areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Big Bend area.

Strong afternoon winds could generate and transport light amounts of patchy blowing dust into portions of West Texas, possibly raising the daily PM10 and PM2.5 AQIs to the lower to middle end of the "Moderate" range in parts of the Midland-Odessa area and possibly the lower end of the "Moderate" range in parts of the El Paso area, with highest concentrations in the afternoon and evening.

Otherwise in the South Plains, moderate to strong winds and lower incoming background levels should help keep air quality in the "Good" range in most spots.
