Forecast Discussion:

The airport reported several hours yesterday with wind gusts over 30mph! This provided plenty of dispersion, preventing any accumulation of air pollution. Both ozone and PM10 easily stayed in the Good AQI range yesterday.

Looking ahead, we don't expect much change in the forecast. Easterly breezes are expected the next couple days, but not as strong as yesterday. However, on Saturday we will once again likely see gusts over 30mph. Overall, stable soils from all the rain recently and good ventilation from the winds should cause particulates to stay in the Good range. As for ozone, there just isn't enough sunlight (shorter day lengths and lower sun angle) this time of year to create enough ozone to be a concern. Both pollutants should stay in the Good AQI range through the forecast period.
