Forecast Discussion

Wednesday 04/25/2018
An Ozone Action Day will be in effect for the Houston area on Wednesday, April 25th. Winds may be light enough and/or incoming background levels high enough for ozone to reach "Unhealthy for Sensitive Groups" on the southeast side of the Houston area, and "Moderate" or possibly higher in parts of the Beaumont-Port Arthur and El Paso areas, and "Moderate" in the Austin and San Antonio areas, with highest concentrations in the afternoon and early evening.

Slightly increased fine particulate background levels associated with continental haze, including contributions from residual light smoke from seasonal burning across the South and Southeastern US, combined with building particulate along and ahead of an advancing front, could be enough to raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the El Paso and Beaumont-Port Arthur areas.

Elsewhere in the state, moderate to strong winds, cooler temperatures, increasing cloud cover, and/or lower incoming background levels should help keep air quality in the "Good" range in most spots.


Thursday 04/26/2018
An Ozone Action Day will be in effect for the El Paso area on Thursday, April 26th. Winds may be light enough and increasing incoming background levels behind the departing front high enough for ozone to reach "Unhealthy for Sensitive Groups" in parts of the El Paso area, and "Moderate" in parts of the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, Houston, Lubbock, San Antonio, Victoria, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

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


Friday 04/27/2018 Outlook
Lingering elevated incoming background levels when combined with sufficient local add-on could be enough for ozone to reach "Unhealthy for Sensitive Groups" on the southeast side of the Houston area, and "Moderate" in parts of the Amarillo, Austin, Beaumont-Port Arthur, Corpus Christi, Dallas-Fort Worth, El Paso, Lubbock, Midland-Odessa, San Antonio, Victoria, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

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


Saturday 04/28/2018 Outlook
Lingering elevated incoming background levels behind a second departing front when combined with sufficient local add-on could be enough for ozone to reach the "Moderate" range in parts of the Amarillo, Austin, Beaumont-Port Arthur, Corpus Christi, Dallas-Fort Worth, El Paso, Houston, Lubbock, San Antonio, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

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