Discussion

Monday 10/16/2017
Increasing incoming background levels behind the departing cold front could be high enough for ozone to reach the lower end of the "Moderate" range mainly in parts of the Austin and San Antonio 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 10/17/2017
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or possibly higher on the south and southwest side of the Houston area and "Moderate" in parts of the Austin, Beaumont-Port Arthur, Corpus Christi, Dallas-Fort Worth, San Antonio, Victoria, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

Increasing urban fine particulate background levels associated with building continental haze 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 Austin, Dallas-Fort Worth, Houston, and San Antonio areas as well.

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

Wednesday 10/18/2017 Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Unhealthy for Sensitive Groups" on the west and northwest side of the Houston area and on the north and northwest side of the San Antonio area; "Moderate" or possibly higher on the north and northwest sides of the Austin and Dallas-Fort Worth areas and in parts of the Corpus Christi and Victoria areas; and "Moderate" in parts of the Beaumont-Port Arthur and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

Slightly elevated urban fine particulate background levels associated with continental haze 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 Austin, Beaumont-Port Arthur, Houston, San Antonio, and Victoria areas as well.

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

Thursday 10/19/2017 Outlook
Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or possibly higher in parts of the Houston area and "Moderate" in parts of the Dallas-Fort Worth and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

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.
