Discussion

Thursday 10/19/2017
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or possibly higher on the north and northwest side of the Dallas-Fort Worth area and on the west side of the Houston area; and "Moderate" in parts of the Austin, San Antonio, Tyler-Longview, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

Elevated urban fine particulate background levels associated with continental haze (with contributions from light amounts of patchy smoke from seasonal agricultural burning across the Southeastern United States, including Texas) combined with sufficient local add-on could also be enough to raise the daily PM2.5 AQI to the lower end of the "Moderate" range in parts of the Dallas-Fort Worth area as well.

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

Friday 10/20/2017
Moderate winds, heavy cloud cover with increasing precipitation, and/or low incoming background levels should help to keep air quality in the "Good" range statewide.

Saturday 10/21/2017 Outlook
Moderate winds, heavy cloud cover with lingering precipitation, and/or low incoming background levels should help to keep air quality in the "Good" range statewide.

Sunday 10/22/2017 Outlook
Moderate to strong winds, lingering cloud cover, and/or low incoming background levels should help to keep air quality in the "Good" range statewide.
