Forecast Discussion

*”Thursday 05/24/2018 “*
*An Ozone Action Day is in effect today for the Dallas-Fort Worth and El Paso areas.* Winds may be light enough and/or incoming background levels high enough for ozone to reach “Unhealthy for Sensitive Groups” on the north and northwest side of the Dallas-Fort Worth area and on the northeast side of the El Paso area; and “Moderate” in parts of the Amarillo, Lubbock, Midland-Odessa, Tyler-Longview, and, if there is enough afternoon sunshine, Houston areas, with highest concentrations in the afternoon and early evening.

Light amounts of patchy smoke from seasonal fires in central/southern Mexico could continue in West Texas, intermittently impacting spots mainly along and west of a line from Big Bend to Guadalupe Mountains National Parks, though the intensity of the smoke is not expected to be enough on its own to raise the daily PM2.5 AQI beyond the “Good” range in this region overall.

Elsewhere in the state, moderate winds, afternoon cloud cover, and/or lower incoming background levels should help keep air quality in the “Good” range in most spots.
