Forecast Discussion

Monday 05/21/2018
Winds may be light enough and/or incoming background levels high enough for ozone to reach "Moderate" or possibly higher on the southwest side of the Dallas-Fort Worth area and "Moderate" in parts of the Amarillo, Lubbock, and Midland-Odessa areas and, if there is enough afternoon sunshine, in the parts of the El Paso and Houston areas, with highest concentrations in the afternoon and early evening.

Light amounts of patchy smoke from agricultural burning in Mexico and Central America may linger in deep South Texas, possibly maintaining the daily PM2.5 AQI at the lower end of the "Moderate" range in parts of the Brownsville-McAllen area. Additionally, slightly elevated urban fine particulate background levels along with increased relative humidity could be enough for the daily PM2.5 AQI to reach the lower end of the "Moderate" range in parts of the El Paso area as well.

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


Tuesday 05/22/2018
Winds may be light enough and/or incoming background levels high enough for ozone to reach "Moderate" or, if there is enough afternoon sunshine, possibly higher on the north and northwest side of the Dallas-Fort Worth area; and "Moderate" in parts of the Amarillo, El Paso, Lubbock, and Midland-Odessa areas and, if there is enough afternoon sunshine, in parts of the Houston and Tyler-Longview 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.


Wednesday 05/23/2018 Outlook

Slightly elevated urban fine particulate background levels associated with continental haze along with increased relative humidity could be enough for the daily PM2.5 AQI to reach the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur and Midland-Odessa areas as well.

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