Winds may be light enough and incoming background levels high enough for ozone levels to reach "Unhealthy for Sensitive Groups" on the south and southwest side of the Houston area and in the Beaumont-Port Arthur area, and "Moderate" or possible higher on the west and southwest side of the Dallas-Fort Worth area, with highest concentrations in the afternoon and early evening. Ozone should also reach "Moderate" levels on the west sides of the Austin and San Antonio areas, in the El Paso, Victoria, and Waco-Killeen areas, and in parts of Northeast Texas. Elsewhere in the state, moderate winds and low incoming background levels should help to keep air quality in the "Good" range.
