Your 7 Day Hill Country Weather Forecast | Wednesday, October 9

WEDNESDAY 10/9/2019
An Ozone Action Day will be in effect on Wednesday for the Houston area. Light to moderate winds, warm temperatures, abundant afternoon sunshine, and/or elevated incoming background levels could be enough for ozone to reach the middle to upper end of the “Unhealthy for Sensitive Groups” range on the northwest side of the Houston area; the lower to middle end of the “Moderate” range in parts of the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, and Waco-Killeen areas; and possibly the lower end of the “Moderate” range in parts of the Corpus Christi, Tyler-Longview and Victoria areas, with highest concentrations in the afternoon and early evening.

Increased incoming urban fine particulate background levels associated with continental haze (including contributions from residual light smoke from seasonal fires across the South and Southeast U.S.) may briefly filter into portions of East, Southeast, and Central Texas and could raise the daily PM2.5 AQI to the lower to middle end of the “Moderate” range in parts of the Austin and Beaumont-Port Arthur areas and the upper end of the “Good” range (perhaps with an isolated low “Moderate” or two) in parts of the Houston and Tyler-Longview areas.

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

THURSDAY 10/10/2019
Should the seasonal burning continue across the South and Southeast U.S., very light amounts of residual smoke may linger across portions of East Texas, although despite potential brief spikes in hourly fine particulate levels, the intensity of the smoke is not expected to be enough to raise the overall daily PM2.5 AQI beyond the upper end of the “Good” range throughout most of affected region, which primarily includes parts of the Beaumont-Port Arthur and Tyler-Longview areas.

Otherwise across East Texas and elsewhere in the state, moderate to strong winds, cooler temperatures, and low incoming background levels associated with an approaching cold front should help keep air quality in the “Good” range in most spots statewide.

FRIDAY 10/11/2019
Should the seasonal burning continue across the South and Southeast U.S., very light amounts of residual smoke may linger across portions of East Texas, although despite potential brief spikes in hourly fine particulate levels, the intensity of the smoke is not expected to be enough to raise the overall daily PM2.5 AQI beyond the upper end of the “Good” range throughout most of affected region, which primarily includes parts of the Beaumont-Port Arthur and Tyler-Longview areas.

Otherwise across East Texas and elsewhere in the state, moderate to strong winds, cooler temperatures, increased cloud cover with precipitation, and low incoming background levels associated with an advancing cold front should help keep air quality in the “Good” range in most spots statewide.
