Forecast Discussion:

Fairly typical air quality yesterday, both PM10 and PM2.5 ended up in the Moderate AQI range, while ozone remained in the Good range. We are not expecting any significant changes to the weather and air quality the next couple days. On Friday, a trough moving through the region will bring gusty easterly winds to the area. These winds may be strong enough to kick up some localized dust, increasing PM10 concentrations.

Over the weekend, are are forecasting PM10 levels to lower into the Good AQI range due to less dust-generating work activities. However, PM2.5 is expected to hang on to the Moderate category due to more fireplace activity. Ozone, as is typical this time of year, is forecast to stay in the Good AQI range through the forecast period.
