If there is enough afternoon sunshine, winds may be light enough, temperatures warm enough, and incoming background levels high enough for ozone to possibly reach "Moderate" levels on the west and southwest side of the Houston area and on the southwest side of the Dallas-Fort Worth area, with highest concentrations in the afternoon and early evening. Light amounts of smoke from agricultural burning in Mexico and Central America may continue in South Texas along the Rio Grande, but concentrations will likely not be high enough to raise fine particulate beyond the "Good" range. Elsewhere in the state, moderate winds and lower incoming background levels should help to keep air quality in the "Good" range.
