Forecast Discussion:

Particulate levels stayed a little higher than anticipated yesterday with both PM10 and PM2.5 ending up in the Moderate AQI range. However, so far this morning particulate levels are looking better. This is due to the weather system currently moving through the area helping clear out the air a bit. PM10 is forecast to drop into the Good range today and remain there through the weekend with less dust generating work activities. PM10 will likely return to the Moderate range again on Monday and Tuesday. PM2.5 on the other hand, will likely increase pretty quick beginning tonight with more fireplace usage and calmer conditions settling in as the trough moves off to the east. PM2.5 is forecast to remain in the Moderate category through the forecast period.
