Patchy smoke from agricultural burning in Mexico and Central America should cover much of the middle of the state and will likely spread into Northwest Texas to mainly along and east of a line from Big Bend to Pecos to Dalhart and along and west of a line from Port Lavaca to Sherman and fine particulate could possibly reach "Moderate" levels in portions of this area, with highest concentrations most likely in South, Central, and Southwest Texas. Elsewhere in the state, moderate winds and lower incoming background levels should help to keep air quality in the "Good" range.
