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

Slightly elevated urban fine particulate levels associated with light winds and limited vertical mixing could be enough to 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 El Paso area.

Otherwise in the state, moderate winds, cool temperatures, lingering cloud cover, and/or low incoming background levels should help keep air quality in the "Good" range in most spots.

Light winds, abundant afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the lower end of the "Moderate" range in parts of the Houston area, with highest concentrations in the afternoon and early evening.

Slightly elevated urban fine particulate background levels over portions of Far West Texas associated with light winds and limited vertical mixing could be enough to raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the El Paso area.

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

Light winds, sufficient afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the lower end of the "Moderate" range in parts of the Houston area, with highest concentrations in the afternoon and early evening.

Suspended blowing dust being generated and transported from parts of Arizona and New Mexico, associated with elevated winds along and behind an advancing cold frontal boundary filtering into portions of the Texas Panhandle and Northwest Texas, along with patchy blowing dust being generated in and transported through portions of Far West Texas, may raise the daily PM10 levels to the lower end of the "Moderate" range in parts of the El Paso, 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 Amarillo area, with highest concentrations in the afternoon and evening hours. Associated PM2.5 levels could also reach the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Amarillo, El Paso, Lubbock, and Midland-Odessa areas too.

Depending on the amount of agricultural and industrial burning activity across portions of Mexico and Central America, light amounts of transported smoke could contribute towards slightly increased particulate matter over portions of Deep South and Southwest 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 Brownsville-McAllen area and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Laredo area.

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

Light amounts of suspended dust generated the previous day associated with the passing of the frontal boundary, along with persistent elevated morning and afternoon winds, could be enough to raise the daily PM10 AQI to the lower to middle of the "Moderate" range in parts of the Amarillo, Lubbock and Midland-Odessa areas.

Slightly elevated fine particulate background levels associated with lingering amounts of smoke from agricultural and industrial burning in Mexico and Central America may persist ahead of an advancing cold front in portions of Deep South as well as Southwest Texas and could be enough for the daily PM2.5 AQI to reach the lower to middle of the "Moderate" range in parts of the Brownsville-McAllen area and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Laredo area.

Elsewhere in the state, moderate winds, mild to cool temperatures, building 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 9:55 AM on Tuesday, March 2nd, 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.
