Discussion

Monday 10/23/2017
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" in parts of the Corpus Christi, Dallas-Fort Worth, Houston, 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
Incoming background levels ahead of a reinforcing front may remain high enough for ozone to reach "Moderate" or possibly higher on the south and southeast side of the Houston area and in parts of the Corpus Christi area and "Moderate" in parts of the Beaumont-Port Arthur and Victoria 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 and Houston areas.

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

Wednesday 10/25/2017 Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or possibly higher on the south and southeast sides of the Austin, Houston, and San Antonio areas and in parts of the Brownsville-McAllen and Corpus Christi areas; and "Moderate" in parts of the Beaumont-Port Arthur, Dallas-Fort Worth, Victoria, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.
