Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or possibly higher on the north and northeast side of the Houston area and "Moderate" in parts of the Dallas-Fort Worth and El Paso 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.

Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" in parts of the Dallas-Fort Worth and El Paso areas, with highest concentrations in the afternoon and early evening. Slightly increased urban fine particulate background levels 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 and/or lower incoming background levels should help to keep air quality in the "Good" range.
