Forecast Discussion

Moderate winds, mild temperatures, and/or low incoming background levels should help keep air quality in the "Good" range in most spots statewide.

Strong afternoon winds could generate and transport intense blowing dust into portions of West Texas and the South Plains, and could raise the daily PM10 AQI to the upper end of the "Moderate" range or possibly higher in parts of the Lubbock area and the middle to upper end of the "Moderate" range in parts of the El Paso and Midland-Odessa areas. The associated PM2.5 AQI could also reach the lower to middle end of the "Moderate" range in parts of the Lubbock area and possibly the lower end of the "Moderate" range in parts of the El Paso and Midland-Odessa areas as well.

Light amounts of residual smoke from potential seasonal fires across the Southeast U.S. may filter into portions of Southeast Texas mainly along the coast, possibly raising the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Houston area and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Beaumont-Port Arthur and Corpus Christi areas.

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

Slightly increased fine particulate background levels may build up along and ahead of an advancing cold front that is expected to stall/dissipate over Deep South Texas, where the daily PM2.5 AQI could reach the lower to middle end of the "Moderate" range in parts of the Brownsville-McAllen area.

Elsewhere in the state, moderate winds, mild to cool temperatures, increased cloud cover with precipitation over Southeast Texas, and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.

Light to moderate winds, warm temperatures, abundant afternoon sunshine, and slightly 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 Austin, San Antonio, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

A slight increase in urban fine particulate background levels associated with light morning winds, increasing humidity, and limited vertical mixing could possibly raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Austin area and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Corpus Christi and San Antonio areas, with highest concentrations in the morning and evening.

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

This forecast was last updated at 9:00 AM on Monday, November 23th, 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.
