Forecast Discussion

Wednesday 09/19/2018
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 and northwest side of the Houston area; "Moderate" in parts of the Dallas-Fort Worth, Tyler-Longview, and, if there is enough afternoon sunshine, Beaumont-Port Arthur areas; and the upper end of the "Good" range (with perhaps an isolated low "Moderate" or two) in parts of the Waco-Killeen area, with the highest concentrations in the afternoon and early evening.

Residual smoke from agricultural fires across the South Central and Southeastern United States (including in Texas) is expected to continue with increased fine particulate background levels primarily in East Texas, possibly raising the daily PM2.5 AQI to the "Moderate" range on average in parts of the Tyler-Longview area and the upper end of the "Good" range on average in parts of the Beaumont-Port Arthur area.

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


Thursday 09/20/2018
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 northwest side of the Houston area, and the lower end of the "Moderate" range in parts of the Dallas-Fort Worth area, with the highest concentrations in the afternoon and early evening.

Residual smoke from agricultural fires across the South Central and Southeastern United States (including in Texas) is expected to linger with increased fine particulate background levels primarily in East Texas, possibly raising the daily PM2.5 AQI to the "Moderate" range on average in parts of the Tyler-Longview area and the upper end of the "Good" range on average in parts of the Beaumont-Port Arthur area.

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


Friday 09/21/2018 Outlook
Moderate to strong winds, heavy cloud cover with precipitation, and/or lower incoming background levels should help keep air quality in the "Good" range in most spots statewide.


Saturday 09/22/2018 Outlook
Winds may be light enough and/or incoming background levels high enough for ozone to reach the lower end of the "Moderate" range in parts of the El Paso area, with the highest concentrations in the afternoon and early evening.

Light amounts of residual smoke from agricultural fires across the South Central and Southeastern United States (including in Texas) is expected to briefly return over portions of North Central and East Texas, though the limited intensity of the smoke along with continuing precipitation in the area should help keep the daily PM2.5 AQI at the upper end of the "Good" range overall on average in the affected areas, which includes parts of the Beaumont-Port Arthur, Dallas-Fort Worth, and Tyler-Longview areas.

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