TUESDAY 4/16/2019
An Ozone Action Day is in effect today for the Houston area. Winds may be light enough and/or incoming background levels high enough for ozone to reach “Unhealthy for Sensitive Groups” on the north side of the Houston area; the upper end of the “Moderate” range or possibly higher on the north side of the San Antonio area and in parts of the El Paso area; the middle to upper end of the “Moderate” range in parts of the Beaumont-Port Arthur, Dallas-Fort Worth, Midland-Odessa, and Waco-Killeen areas; the lower to middle end of the “Moderate” range in parts of the Amarillo, Austin, Big Bend, Corpus Christi, Lubbock, and Tyler-Longview areas; and the lower end of the “Moderate” range in parts of the Victoria area, with highest concentrations in the afternoon and early evening.

Elsewhere in South and Southwest Texas along the Rio Grande, moderate to strong winds and/or lower incoming background levels should help keep air quality in the “Good” range in most spots.

WEDNESDAY 4/17/2019
Incoming background levels may remain high enough for ozone to reach the upper end of the “Moderate” range or possibly higher on the north and northwest side of the Houston area; the lower to middle end of the “Moderate” range in parts of the El Paso, Lubbock, and Tyler-Longview areas; the lower end of the “Moderate” range in parts of the Amarillo, Beaumont-Port Arthur, Big Bend, Dallas-Fort Worth, Midland-Odessa, and Waco-Killeen 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.

Smoke from agricultural burning in Mexico and Central America will surge back into Texas from south to north on Tuesday, impacting mainly parts of South, South Central, and Southwest Texas, but the smoke could spread far enough inland to reach parts of the Permian Basin and South Plains. Overall, depending on the timing, duration, and intensity 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 Brownsville-McAllen, Laredo, and San Antonio areas; the lower end of the “Moderate” range in parts of the Austin, Big Bend, Corpus Christi, Lubbock, Midland-Odessa, and Victoria areas; and the upper end of the “Good” range (perhaps with an isolated low “Moderate” or two) in parts of the Waco-Killeen area.

Strong afternoon winds could generate and transport patchy blowing dust into far West Texas, possibly raising the daily PM10 AQI to the middle to upper end of the “Moderate” range and the daily PM2.5 AQI to the lower to middle end of the “Moderate” range in parts of the El Paso area, with highest concentrations in the afternoon and evening.

THURSDAY 4/18/2019
Incoming background levels may be high enough for ozone to reach the lower to middle end of the “Moderate” range in parts of the Big Bend, Brownsville-McAllen, Lubbock, and Midland-Odessa areas; the lower end of the “Moderate” range in parts of the El Paso area; and the upper end of the “Good” range (perhaps with an isolated low “Moderate” or two) in parts of the Houston area, with highest concentrations in the afternoon and early evening.

Smoke from agricultural burning in Mexico and Central America will continue over much of the eastern half of Texas but will begin retreating eastward as a strong cold front moves across the state, rapdily decreasing particulate levels from the northwest to southeast as the front arrives. At times over the course of the day, the smoke will impact portions of Texas along and east of a line from Eagle Pass to Wichita Falls, with the most dense smoke lingering the longest over mainly South and Southeast Texas. Overall, depending on the timing, duration, and intensity of the smoke (along with lingering precipitation), the daily PM2.5 AQI is forecast to reach the upper end of the “Moderate” range or possibly higher in parts of the Brownsville-McAllen and Corpus Christi areas; the middle to upper end of the “Moderate” range in parts of the Laredo and Victoria areas; the lower to middle end of the “Moderate” range in parts of the Beaumont-Port Arthur, Houston, Tyler-Longview, and Waco-Killeen areas; and the lower end of the “Moderate” range in parts of the Austin, Dallas-Fort Worth, and San Antonio areas, with highest concentrations occurring during the first half of the day.

Lingering suspended blowing dust generated the previous day is expected to be transported across the state along and behind the advancing front, possibly raising particulate levels at times as it progresses, though the intensity and duration of the dust is not expected to be enough to raise the daily PM10 AQI beyond the “Good” range.

Elsewhere in the northern Panhandle, moderate to strong winds, cool temperatures, and/or lower incoming background levels should help keep air quality in the “Good” range in most spots.
