Today's Texas Air Quality Forecast

Cold to cool temperatures, widespread precipitation, and/or lower incoming background levels are forecast to be enough to keep ozone levels in the "Good" range for the majority of the state.

A stationary front currently extending across South Central Texas will eventually be overtaken by another, stronger cold front that's moving southward out of Southern Oklahoma and could reach Central Texas by the late afternoon/early evening hours and will bring gusty winds and widespread rain and wintry precipitation to most of Texas with coverage increasing through the evening and overnight. Dense fog is currently keeping PM2.5 concentrations slightly elevated in Central and North Central Texas, but the incoming precipitation will keep it from being sustained throughout the day. Light density smoke and aerosols could be transported over deep South Texas later today from burning, industrial, and urban activity in Southern Mexico as south/southeasterly winds prevail ahead of the aforementioned boundaries. The daily PM2.5 AQI may reach the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur and Houston areas and the upper end of the "Good" range in a majority of the Austin, Brownsville-McAllen, Corpus Christi, Dallas-Fort Worth, and Laredo areas.

Light to moderate winds may sustain slightly elevated urban fine particulate matter at times in far West Texas but likely precipitation and increased vertical mixing could result in the PM2.5/PM10 AQIs netting out in the upper end of the "Good" range in a majority of the El Paso area.

Cold temperatures, widespread precipitation, and/or lower incoming background levels are forecast to be enough to keep ozone levels in the "Good" range for the majority of the state.

Wintry precipitation will be present across most of Texas as the cold front pushes through the deep South region during the morning hours. Elevated relative humidity in South Texas could slightly elevate fine particulate matter briefly as the boundary moves through, but ongoing precipitation and gusty winds are expected to provide sufficient dispersion. The daily PM2.5 and PM10 AQIs are forecast to remain firmly in the "Good" range for most areas across the state.

Cold temperatures, widespread precipitation, and/or lower incoming background levels are forecast to be enough to keep ozone levels in the "Good" range for the majority of the state.

Lingering wintry precipitation will persist across a large portion of Texas Sunday morning as gusty northerly winds continue behind the cold front, which is expected to be located in Northern Mexico by this time. This precipitation will likely end by the early afternoon but with the lack of surface moisture and any significant pollutant sources, the daily PM2.5 and PM10 AQIs are expected to remain firmly in the "Good" range in most areas.

Light, variable afternoon and evening winds could slightly increase urban fine particulate matter in far West Texas as the daily PM2.5/PM10 AQIs net out in the upper end of the "Good" range in a majority of the El Paso area.

Cold temperatures, scattered cloud cover, and/or lower incoming background levels are forecast to be enough to keep ozone levels in the "Good" range for the majority of the state.

High pressure will build over Texas on Monday as northerly winds continue to prevail over the eastern two thirds of the state. Light to moderate winds will move into Central and North Central Texas and could slightly elevate urban fine particulate matter at times in the more populated parts of the region. Dry conditions will be present throughout all of Texas and with the lack of any significant pollutant sources, the daily PM2.5 AQI could net out in the upper end of the "Good" range for the majority of the Austin, Dallas-Fort Worth, Houston, San Antonio, Tyler-Longview, and Waco-Killeen areas.

Very light winds and limited vertical mixing are expected to elevate urban fine particulates in far West Texas with the daily PM2.5/PM10 AQIs increasing into the lower end of the "Moderate" range in parts of the El Paso area.

Cold to cool temperatures, scattered cloud cover, and/or lower incoming background levels are forecast to be enough to keep ozone levels in the "Good" range for the majority of the state.

Lingering high pressure is forecast to result in light, variable morning winds that will turn out of the south during the afternoon and evening hours. Urban fine particulate matter will be the primary pollutant source and could slightly elevate concentrations into the "Moderate" range in the more populated areas. The daily PM2.5 AQI is forecast to net out in the lower end of the "Moderate" range in parts of the Dallas-Fort Worth and Houston areas and the upper end of the "Good" range (possibly with an isolated low "Moderate") in a majority of the Austin, Brownsville-McAllen, San Antonio, Tyler-Longview, and Waco-Killeen areas.

Light, variable winds will elevate urban fine particulate matter as stable atmospheric conditions limit dispersion in far West Texas. The daily PM2.5/PM10 AQIs are forecast to remain in the lower end of the "Moderate" range in parts of the El Paso area.
