Forecast Discussion

*”Monday 12/17/2018 “*
Elevated urban fine particulate levels associated with light winds and limited vertical mixing could be enough for the daily PM2.5 AQI to reach “Moderate” in parts of the Beaumont-Port Arthur, El Paso, Houston areas, and San Antonio areas, and the upper end of the “Good” range in the Tyler-Longview and Victoria areas, with the highest concentrations in the morning and evening. The stagnant conditions could also allow PM10 levels to increase in the El Paso area during the morning and evening as well, though the daily PM10 AQI is not expected to reach beyond the “Good” range overall.

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