Forecast Discussion

Light winds, warm temperatures, abundant afternoon sunshine, and/or increased incoming background levels could be enough for ozone to reach the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the El Paso area, with highest concentrations in the afternoon and early evening.

Light to moderate amounts of patchy smoke from wildfires in Colorado and New Mexico may continue lingering over the Texas Panhandle and the Permian Basin while filtering over portions of North Central and Central Texas, mainly behind and south of a stalling frontal bounday across Central Texas, though much of the smoke may remain aloft. Depending on the density and duration of the smoke, the daily PM2.5 AQI could rise to the lower end of the "Moderate" range in parts of the Amarillo, Dallas-Fort Worth, Lubbock, and Waco-Killeen areas; and possibly the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Austin, Midland-Odessa, and San Antonio areas.

Light amounts of remnant smoke from seasonal fires across the Southeast U.S. (including in Texas) may continue over portions of East and Southeast Texas and could raise the daily PM2.5 AQI to the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Beaumont-Port Arthur and Tyler-Longview areas. Additionally, light winds and limited vertical mixing could increase urban fine particulate background levels enough for the daily PM2.5 and PM10 AQIs to reach the lower to middle of the "Moderate" range in parts of the El Paso area, 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 winds, warm temperatures, sufficient afternoon sunshine, and/or increased incoming background levels could be enough for ozone to reach the lower to middle of the "Moderate" range in parts of the El Paso area; the lower end of the "Moderate" range in parts of the Houston and Midland-Odessa areas; and possibly the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Amarillo, Austin, Dallas-Fort Worth, and San Antonio areas, with highest concentrations in the afternoon and early evening.

Depending on the amount of continuing fire activity across the Southwest U.S. as well as seasonal fires across the Southeast U.S. (including in Texas), light amounts of transported smoke could contribute towards slightly increased particulate matter over portions of the Texas Panhandle, Southeast, and East Texas. The duration and density of the possible smoke could raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Amarillo, 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 Dallas-Fort Worth and Tyler-Longview areas. Additionally, light winds and limited vertical mixing could increase urban fine particulate background levels enough for the daily PM2.5 and PM10 AQIs to reach the lower to middle of the "Moderate" range in parts of the El Paso area as well.

Limited vertical mixing, elevated relative humidity with fog, and light amounts of building continental haze over the Northern two-thirds the state respectively could enhance morning fine particulate levels over the majority of the state with the exception of Far West Texas and Deep South Texas, though the daily PM2.5 AQI is expected to remain in the "Good" range overall in the Austin, Dallas-Fort Worth, Laredo, Lubbock, Midland-Odessa, San Antonio, Victoria, and Waco-Killeen areas with moderate afternoon winds and deeper vertical mixing.

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 temperatures, sufficient afternoon sunshine, and/or increased incoming background levels could be enough for ozone to reach the lower to middle end of the "Moderate" range in parts of the El Paso area; the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur, Dallas-Fort Worth, Houston, San Antonio areas; and possibly the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Austin, San Antonio, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

Depending on the amount of continuing fire activity across the Southeast U.S. (including in Texas), light amounts of transported smoke could contribute towards slightly increased particulate matter over portions of Southeast and East Texas. The duration and density of the possible smoke could raise the daily PM2.5 AQI to 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.

Suspended blowing dust transported along an advancing strong cold frontal boundary could arrive in the Panhandle early in the day, though the intensity and duration of the suspended dust is not expected to be enough to raise the daily PM10 AQI beyond the "Good" range throughout most of the impacted region, which includes parts of the Amarillo and Lubbock 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.

This forecast was last updated at 11:00 AM on Monday, October 19th, 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.
