Forecast Discussion:

The rain the past couple days has helped bring Good air quality across the entire state. We expect showers to become more isolated throughout the day as the low pressure system moves off to the east. Air quality should continue to be great today, but we do expect to see changes beginning tomorrow. As the low moves off to the east, cool, calm conditions will settle in over the region and allow particulate levels to trend back up. PM2.5 will be the main pollutant to watch because there will likely be an increase in fireplace usage due to the cooler temperatures. As a result, we forecast PM2.5 to reach into the Moderate AQI category starting tomorrow. PM10 is forecast to remain in the Good range with more stable soils from the rain.
