Discussion

Friday 10/20/2017
Slightly elevated particulate levels are lingering across parts of North Central and Northeast Texas this morning, likely due to residual smoke from seasonal fires during the previous few days. Presuming the absence of significant new fires today, the particulate levels should drop over the course of the day, resulting in daily PM2.5 AQIs at the upper end of the "Good" range overall for most spots in the affected region.

Otherwise, moderate winds, heavy cloud cover with precipitation, and/or low incoming background levels should help to keep air quality in the "Good" range statewide.

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

Monday 10/23/2017 Outlook
Increasing background levels and decreasing winds along with plentiful sunshine in the wake of the cold front could be enough to raise ozone to "Moderate" or possibly higher in parts of the Brownsville-McAllen, Corpus Christi, Houston, and San Antonio areas and "Moderate" in parts of the Austin, Dallas-Fort Worth, 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 to keep air quality in the "Good" range.

Tuesday 10/24/2017 Extended Outlook
Incoming background levels ahead of a reinforcing front may remain high enough for ozone to reach "Moderate" or possibly higher in parts of the Corpus Christi and Houston areas and "Moderate" in parts of the Austin, Beaumont-Port Arthur, Brownsville-McAllen, Dallas-Fort Worth, San Antonio, Victoria, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

Depending on the reemergence of smoke from seasonal burning across the Southeastern United States, wind patterns may be favorable for increasing fine particulate background levels across parts of Southeast Texas and could raise the daily PM2.5 AQI to the lower end of the "Moderate" range primarily in parts of the Beaumont-Port Arthur area.

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