An asterisk (*) indicates that an Ozone Action Day is or will be in effect for the indicated region.
A caret (^) indicates that levels of PM may exceed the applicable short-term NAAQS. For more information see the following TCEQ websites:Air Pollution from Particulate Matter and Voluntary Tips for Citizens and Business to Reduce Emissions.

Forecast Discussion

Light to moderate winds, warm temperatures, sufficient afternoon sunshine, and/or elevated lingering background levels could be enough for ozone to reach the middle to upper end of the "Moderate" range in parts of the Dallas-Fort Worth and Houston areas; the lower to middle end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Bryan-College Station, El Paso, San Antonio, 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 Amarillo, Lubbock, and Midland-Odessa areas, with highest concentrations in the afternoon and early evening.

Light winds and slightly increased urban fine particulate background levels may allow the daily PM2.5 AQI to reach the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, El Paso, Houston, San Antonio, and Tyler-Longview areas and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Bryan-College Station and Waco-Killeen areas. Additionally, very light amounts of smoke from seasonal agricultural fire activity across portions of the Southeastern U.S. including in Northeast Texas may linger over parts of East Texas while beginning to filter into portions of North Central Texas. Fine smoke particulates combined with slightly increased urban fine particulate background levels may help elevate the daily PM2.5 AQI to possibly reach the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur, Dallas-Fort Worth, and Tyler-Longview areas as a result.

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 elevated incoming background levels could be enough for ozone to reach the middle of the "Moderate" range in parts of the Dallas-Fort Worth and Houston areas and the lower end of the "Moderate" range in parts of the Amarillo, Austin, Beaumont-Port Arthur, Bryan-College Station, El Paso, Lubbock, Midland-Odessa, San Antonio, Tyler-Longview, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

Light winds and limited atmospheric mixing enhancing urban fine particulate concentrations could be sufficient for the daily PM2.5 AQI to reach the lower end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Bryan-College Station, Dallas-Fort Worth, El Paso, Houston, San Antonio, and Tyler-Longview areas and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Waco-Killeen area. Additionally, depending on the amount of seasonal burning activity across the Southeastern U.S., easterly windflow expected to develop could begin to push light amounts of residual smoke over portions of eastern Texas. For this reason, smoke contributions with the slightly elevated urban fine particulate concentrations would help elevate the daily PM2.5 AQI to possibly reach the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur 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.

Depending on the seasonal burning activity across the Southeastern U.S., southerly winds may continue to steer light amounts of smoke into portions of Northeast and Southeast Texas that could elevate the daily PM2.5 AQI into the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur 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.

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

This forecast was last updated at 10:10 AM on Thursday, October 21st, 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.
