Forecast Discussion:
Surprisingly, ozone managed to reach the low Moderate AQI range yesterday with breezy winds. Ozone did still improve a little from the day prior though, and we expect the improvement to continue. Breezy southeasterly winds will continue due to the position of the high pressure system to our northeast. Good ventilation with these winds also help lower particulate levels as well. Both ozone and PM10 are forecast to trend down through tomorrow, then slowly start to trend up with weaker winds over the area. Overall though, we expect both pollutants to stay in the Good AQI range.- R. Nicoll
