Forecast Discussion

Warm temperatures, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the upper end of the "Good" range (perhaps with an isolated low "Moderate") in parts of the Amarillo, Austin, El Paso, Dallas-Fort Worth, Lubbock, Midland-Odessa, and San Antonio areas.

Suspended blowing dust generated the previous day along with persistent elevated daytime winds across Far West Texas, the Permian Basin, and the lower Texas Panhandle is expected to continue to generate blowing dust and transport the fine particulate matter eastward towards the South Central and North Central parts of the state associated with the advancing cold frontal boundary, raising PM2.5/PM10 levels as the front arrives. PM2.5/PM10 spikes may possibly rise into the "Unhealthy for Sensitive Groups" range at times primarily across the Permian Basin with lighter amounts in the "Moderate" range over the lower Texas Panhandle, Big Bend region, Far West Texas, Texas Hill Country region, and North Central Texas. With the timing of thundershowers over North Central Texas associated with the cold front expected to be over by early afternoon, the intensity and duration of the generated and transported blowing dust is forecast to contribute enough fine particulate matter to raise the overall daily PM2.5 AQI to the middle of the "Moderate" range in parts of the Midland-Odessa area; to the lower end of the "Moderate" range in parts of the Big Bend and El Paso areas, and net out in the upper end of the "Good" range for the majority of the Dallas-Fort Worth and Lubbock areas. The daily PM10 AQI is forecast to net out in the upper end of the "Good" range for the majority of the El Paso area as well.

The residual smoke from seasonal burning activity across the Lower Mississippi Valley, Southeast U.S., and Southeast and East Texas in addition to agricultural burning activity across portions of Mexico and Central America filtering over South Texas is expected to linger ahead of the advancing cold front, with associated fine particulate levels dropping later in the day from west to east behind the front. Although intermittent heavy precipitation associated with the cold front should significantly reduce fine particulate levels at times, light amounts of smoke along with elevated relative humidity levels may linger over South Texas, South Central Texas, Southeast Texas, and along the coastal bend of Texas long enough for the daily PM2.5 AQI to still reach the lower end of the "Moderate" range in parts of the Austin, Brownsville-McAllen, Corpus Christi, Houston, Laredo, San Antonio, and Victoria areas and the upper end of the "Good" range (perhaps with an isolated low "Moderate") in parts of the Beaumont-Port Arthur, Bryan-College Station, Dallas-Fort Worth, Tyler-Longview, and Waco-Killeen areas.

Otherwise and elsewhere in the upper Texas Panhandle, moderate winds, mild temperatures, and/or lower incoming background should help keep air quality in the "Good" range in most spots.

An Ozone Action Day will be in effect on Saturday for the Houston-Galveston area. Light winds, warm 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 on the East to Southeast side of the Houston area, the middle to upper end of the "Moderate" range in parts of the Austin and San Antonio areas, the lower to middle end of the "Moderate" range in parts of the Beaumont-Port Arthur, Bryan-College Station, and Dallas-Fort Worth areas, the lower end of the "Moderate" range in parts of the Brownsville-McAllen, Corpus Christi, Laredo, Tyler-Longview, Victoria, and Waco-Killeen areas, and the upper end of the "Good" range (perhaps with an isolated low "Moderate") in parts of the Amarillo, El Paso, Lubbock, and Midland-Odessa areas.

Enough suspended dust generated the previous day over the Permian Basin may linger over portions of South Central Texas, North Central Texas, and the upper portion of the Rio Grande Valley, with the higher concentrations expected over North Central Texas. PM2.5/PM10 levels may reach the upper end of the "Moderate" range or possibly higher in the morning hours with decreasing concentrations forecast during the afternoon and evening. The intensity and duration of the suspended dust is forecast to raise the overall daily PM2.5 AQI to the lower to middle end of the "Moderate" range in parts of the Dallas-Fort Worth and Waco-Killeen areas and net out in the upper end of the "Good" range throughout the majority of the Austin and San Antonio areas. The daily PM10 AQI is forecast to reach the lower end of the "Moderate" range in parts of the Dallas-Fort Worth area as well.

Fine urban particulate levels owing to limited dispersion from light winds and/or limited vertical mixing are expected to increase the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Houston area and to the upper end of the "Good" range (perhaps with an isolated low "Moderate") in parts of the Beaumont-Port Arthur area.

Lingering residual smoke is expected to weaken and dissipate throughout the majority of the state although isolated patches of the weakening smoke could be enough to raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Brownsville-McAllen area.

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

Light winds, warm temperatures, sufficient afternoon sunshine, and/or elevated lingering background levels could be enough for ozone to reach the middle of the "Moderate" range in parts of the Dallas-Fort Worth area, the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Bryan-College Station, Houston, San Antonio, Tyler-Longview, and Waco-Killeen areas, and the upper end of the "Good" range (perhaps with an isolated low "Moderate") in parts of the Amarillo, El Paso, Lubbock, and Midland-Odessa areas.

Light amounts of lingering residual smoke from agricultural burning activity across portions of Mexico and Central America over South Texas and along the Rio Grande Valley as well as coastal bend of Texas combined with elevated relative humidity could enhance fine particulate background levels enough to raise the overall daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Brownsville-McAllen, Corpus Christi, Laredo, and Victoria areas.

Light winds, limiting pollutant dispersion, along with some light urban pollutant carryover from the previous day combined with residual smoke from seasonal fires across portions of Southeast Texas may be enough to raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur area and to the upper end of the "Good" range (perhaps with an isolated low "Moderate") in parts of the Austin, Bryan-College Station, Dallas-Fort Worth, Houston, San Antonio, Tyler-Longview, and Waco-Killeen areas.

Otherwise and elsewhere in Big Bend region, moderate winds, mild to warm temperatures, and/or lower incoming background should help keep air quality in the "Good" range in most spots.

Light winds, warm 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 Houston area, the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Bryan-College Station, Dallas-Fort Worth, San Antonio, and Waco-Killeen areas, and the upper end of the "Good" range (perhaps with an isolated low "Moderate") in parts of the Tyler-Longview area.

Patchy residual smoke from agricultural burning in Mexico and Central America is expected to continue expanding northward over Deep South Texas, along the Rio Grande Valley and coastal bend of Texas, and over portions of South Central Texas. Meanwhile, residual smoke associated with seasonal fire activity across East and Southeast Texas is forecast to elevate fine particulate levels over these portions of the state. Combined with rising relative humidity levels over the eastern two-thirds of the state, the coverage and intensity of the smoke is forecast to raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Bryan-College Station, Corpus Christi, Houston, Laredo, San Antonio, Tyler-Longview, and Victoria areas and to the upper end of the "Good" range (perhaps with an isolated low "Moderate") in parts of the Dallas-Fort worth and Waco-Killeen areas.

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

Slightly increasing fine particulate levels over the eastern two-thirds of the state due to a combination of expanding smoke from agricultural burning activity in Mexico and Central America as well as seasonal fire activity across East and Southeast Texas in addition to elevated relative humidity levels will raise PM2.5 levels for most areas in these regions of the state. The overall density and coverage of the smoke is forecast to raise the daily PM2.5 to the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Bryan-College Station, Corpus Christi, Dallas-Fort Worth, Houston, Laredo, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas.

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