Forecast Discussion

*”Wednesday 09/19/2018 “*
*An Ozone Action Day is in effect today for the Houston area.* 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 Houston area; “Moderate” in parts of the Dallas-Fort Worth, Tyler-Longview, and, if there is enough afternoon sunshine, Beaumont-Port Arthur areas; and the upper end of the “Good” range (with perhaps an isolated low “Moderate” or two) in parts of the Waco-Killeen area, with the highest concentrations in the afternoon and early evening.

Residual smoke from agricultural fires across the South Central and Southeastern United States (including in Texas) is expected to continue with increased fine particulate background levels primarily in East Texas, possibly raising the daily PM2.5 AQI to the “Moderate” range on average in parts of the Tyler-Longview area and the upper end of the “Good” range on average in parts of the Beaumont-Port Arthur area.

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