Your 7 Day Hill Country Weather Forecast | Friday, October 18

FRIDAY 10/18/2019
Light winds, warming temperatures, and abundant afternoon sunshine could be enough for ozone to reach the lower to middle end of the “Moderate” range in parts of the Houston and Waco-Killeen areas; possibly the lower end of the “Moderate” range in parts of the San Antonio area; and the upper end of the “Good” range (perhaps with an isolated low “Moderate” or two) in parts of the Austin area, with highest concentrations in the afternoon and early evening.

Light winds and limited vertical mixing may allow fine particulate matter to increase in urban portions of the state, particularly in parts of the San Antonio area where the daily PM2.5 AQI could possibly reach the lower end of the “Moderate” range, with highest concentrations in the morning and evening.

Slightly elevated afternoon winds could generate and transport very light amounts of patchy blowing dust into portions of the South Plains and Permian Basin, though the duration and intensity of the possible dust is not expected to be enough to raise the daily PM10 AQI beyond the upper end of the “Good” range throughout most of the Lubbock and Midland-Odessa areas.

Otherwise and 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.

SATURDAY 10/19/2019
Light winds, warm temperatures, and abundant afternoon sunshine could be enough for ozone to reach the lower to middle end of the “Moderate” range in parts of the Houston area, with highest concentrations in the afternoon and early evening.

A Slight increase in fine particulate background levels across portions of Northeast Texas associated with briefly building continental haze (featuring light amounts of residual smoke from seasonal burning across the Southeast U.S) could raise the daily PM2.5 AQI to the upper end of the “Good” range (perhaps with an isolated low “Moderate” or two) in parts of the Tyler-Longview area.

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

SUNDAY 10/20/2019
Light to moderate winds, warm temperatures, and sufficient afternoon sunshine could be enough for ozone to reach the upper end of the “Good” range (perhaps with an isolated low “Moderate” or two) in parts of the Houston area, with highest concentrations in the afternoon and early evening.

Otherwise, moderate to strong winds, increasing cloud cover, and/or low incoming background levels should help keep air quality in the “Good” range in most spots statewide.
