Forecast Discussion

Tuesday 04/07/2020

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 Lubbock area; possibly the lower end of the "Moderate" range in parts of the Amarillo and Houston areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Austin area, with highest concentrations in the afternoon and early evening.

Patchy smoke from agricultural burning in Mexico and Central America will continue in South and Southeast Texas while expanding northward into portions of Central and Northeast Texas to cover much of the eastern half of the state at varying intensities. Overall, depending on the intensity and coverage of the smoke, the daily PM2.5 AQI is forecast to reach the lower to middle end of the "Moderate" range in parts of the Austin, Brownsville-McAllen, Corpus Christi, Houston, San Antonio, and Victoria areas; possibly the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur, Laredo, 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 Dallas-Fort Worth area.

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.


Wednesday 04/08/2020

Light to moderate winds, warm temperatures, sufficient afternoon sunshine, and/or increased incoming 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 area; the lower to middle end of the "Moderate" range in parts of the Houston area; possibly the lower end of the "Moderate" range in parts of the Amarillo, 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 Brownsville-McAllen area, with highest concentrations in the afternoon and early evening.

Patchy smoke from agricultural burning in Mexico and Central America will continue across portions of the eastern half of the state and is forecast to raise the daily PM2.5 AQI to the lower to middle end of the "Moderate" range in parts of the Austin, Brownsville-McAllen, Corpus Christi, Houston, Laredo, San Antonio, and Victoria areas; possibly the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur area; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Waco-Killeen area.

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.


Thursday 04/09/2020 Outlook

Light to moderate winds, warm temperatures, sufficient afternoon sunshine, and/or increased 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 to middle end of the "Moderate" range in parts of the El Paso area; and possibly the lower end of the "Moderate" range in parts of the Dallas-Fort Worth area, with highest concentrations in the afternoon and early evening.

Patchy smoke from agricultural burning in Mexico and Central America will continue across the eastern half of the state ahead of and converging along the leading edge of an advancing cold front, resulting in increased particulate levels as the front approaches followed by a rapid drop behind the front. Overall, depending on the intensity of the smoke and the timing and movement of the front, the daily PM2.5 AQI is forecast to reach the middle to upper end of the "Moderate" range in parts of the Brownsville-McAllen and Corpus Christi areas; the lower to middle end of the "Moderate" range in parts of the Austin, Beaumont-Port Arthur, Houston, Laredo, San Antonio, and Victoria areas; possibly the lower end of the "Moderate" range in parts of the Big Bend and Waco-Killeen areas; and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Dallas-Fort Worth, Midland-Odessa, and Tyler-Longview areas. In all cases, the highest concentrations are expected prior to the arrival of the cold front.

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


Friday 04/10/2020 Outlook

Warm temperatures, abundant afternoon sunshine, and 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, with highest concentrations in the afternoon and early evening.

Light amounts of patchy smoke may continue mainly along and south of a stalling frontal bounday, primarily lingering over portions of South and Southeast Texas and possibly raising the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Brownsville-McAllen and Corpus Christi areas and the upper end of the "Good" range (perhaps with an isolated low "Moderate" or two) in parts of the Houston, Laredo, San Antonio, and Victoria areas.

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