Forecast Discussion:

We have a weak trough moving through the region, which isn't enough for any rain or significant weather, but we will continue to see afternoon breezes. This pattern will generally persist through the forecast period. As a result, we don't expect to see a build up of ozone or PM10. Both pollutants are forecast to remain in the Good AQI range through the forecast period.

The next impactful weather changes looks like it will be during the later half of next week, when a low pressure system is forecast to move through the area. This will likely bring gusty winds, cooler temperatures, and potentially some rain. As for air quality, it will likely only result in a continuation of our great air quality.
