*Discussion*
*”Tuesday 12/12/2017 “*
Moderate winds, cooler temperatures, and/or low incoming background levels associated with a weak cold front should help keep air quality in the “Good” range in most spots statewide.

*”Wednesday 12/13/2017 “*
Light winds and limited vertical mixing could allow sufficient local add-on for the daily PM2.5 AQI to reach the “Moderate” range in parts of the El Paso area, with highest concentrations in the morning and evening.

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

*”Thursday 12/14/2017 Outlook”*
Light winds and limited vertical mixing along with a possible slight increase in urban fine particulate background levels could be enough for the daily PM2.5 AQI to reach the lower end of the “Moderate” range in parts of the Houston area, with highest concentrations in the morning and evening.

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

*”Friday 12/15/2017 Outlook”*
Light winds and limited vertical mixing could allow sufficient local add-on for the daily PM2.5 AQI to reach the “Moderate” range in parts of the El Paso area, with highest concentrations in the morning and evening.

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