Forecast Discussion:
All pollutants ended up in the Good AQI range yesterday. Looking ahead, we don't anticipate any major changes. We expect to see mostly sunny skies, afternoon highs in the mid 60's, and only occasional breezes. Overall, we are forecasting ozone and PM10 to stay in the Good AQI range, while PM2.5 will continue to have potential to reach the low Moderates range.
