Both PM10 and PM2.5 managed to end up in the Good AQI range yesterday, and we even got a little rain in the area yesterday. Today, we are forecasting particulate levels to remain on the lower side, then increase sharply on Friday and over the weekend due to increased wood burning. Then on Monday, particulate levels will like trend back down.
