Forecast Discussion

An Ozone Action Day is in effect today for the El Paso area. Light winds, hot temperatures, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the lower end of the "Unhealthy for Sensitive Groups" range in parts of the El Paso area; the upper end of the "Moderate" range or, if incoming background levels are high enough and depending on shower and thunderstorm activity this afternoon, on the East and Northeast side of the Houston area and on the West to Northwest side of the Dallas-Fort Worth area; the middle to upper end of the "Moderate" range in parts of the Beaumont-Port Arthur area; the middle of the "Moderate" range in parts of the Austin, San Antonio, and Waco-Killeen areas; the lower to middle of the "Moderate" range in parts of the Amarillo, Lubbock, and Midland-Odessa 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.

Light winds, limited vertical mixing, and increased incoming background levels associated with elevated continental haze combined with light amounts of patchy smoke from seasonal fires across portions of the Southeast U.S. (including in eastern Texas) slightly enhancing fine particulate levels could possibly raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Dallas-Fort Worth area and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Beaumont-Port Arthur, Houston, Tyler-Longview, and Waco-Killeen areas, with highest concentrations in the morning and evening.

Otherwise and elsewhere in South Texas and along the coastal bend of Texas, moderate winds and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.

An Ozone Action Day will be in effect Thursday for the Dallas-Fort Worth area. Light winds, hot temperatures, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the lower to middle of the "Unhealthy for Sensitive Groups" range on the Northwest and 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 Houston areas; the middle of the "Moderate" range in parts of the Beaumont-Port Arthur area; the lower to middle of the "Moderate" range in parts of the Amarillo, Lubbock, Midland-Odessa, and San Antonio areas; the lower end of the "Moderate" range in parts of the Austin 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.

Patchy residual smoke associated with seasonal fire activity scattered across the Southeastern U.S. (including in eastern Texas) combined with slightly elevated urban fine particulate background levels associated with continental haze could raise fine particulate matter across portions of North Central, East, and Southeast Texas. Depending on the intensity and duration of the possible smoke, the daily PM2.5 AQI could reach the lower end of the "Moderate" range in parts of the Dallas-Fort Worth and Tyler-Longview areas and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Beaumont-Port Arthur, Houston, and Waco-Killeen areas, with highest concentrations in the morning and evening.

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.

Light to moderate winds, warm to hot temperatures, abundant afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the lower end of the "Unhealthy for Sensitive Groups" range in parts of the El Paso area; the upper end of the "Moderate" range or possibly higher in parts of the Houston area; the middle of the "Moderate" range in parts of the Dallas-Fort Worth area; the lower to middle of the "Moderate" range in parts of the Beaumont-Port Arthur area; the lower end of the "Moderate" range in parts of the San Antonio area, and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Amarillo, Austin, Lubbock, Midland-Odessa, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

Should the seasonal fire activity continue across the Southeastern U.S. (including in eastern Texas), patchy residual smoke combined with slightly elevated urban fine particulate background levels associated with continental haze could raise fine particulate matter across portions of North Central, East, and Southeast Texas. Depending on the intensity and duration of the possible smoke, the daily PM2.5 AQI could reach the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur and Tyler-Longview areas and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Dallas-Fort Worth, Houston, and Waco-Killeen areas, with highest concentrations in the morning and evening.

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.

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

Should the seasonal fire activity continue across the Southeastern U.S. (including in eastern Texas), patchy residual smoke combined with slightly elevated urban fine particulate background levels associated with continental haze could raise fine particulate matter across portions of North Central, East, and Southeast Texas. Depending on the coverage and density of the possible smoke, the daily PM2.5 AQI could reach the lower end of the "Moderate" range in parts of the Tyler-Longview area and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Beaumont-Port Arthur, Dallas-Fort Worth, and Houston areas, with highest concentrations in the morning and evening.

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.

This forecast was last updated at 1:50 PM on Wednesday, August 5th, and is updated daily on normal TCEQ work days and may also be updated on weekends or holidays when air pollution levels are high. Regardless of our forecast, we always recommend that each individual determine what level of activity they should conduct based on the actual local conditions.
