Forecast Discussion:

Good air quality expected to continue through the forecast period for both ozone and PM10. High pressure centered to the north will create calm weather with mostly light easterly winds today. Beginning tonight, we will start to see an increase in cloud cover as an upper-level trough moves into the region. This trough will be fairly weak, and we don't anticipated any significant weather associated with it. After the trough moves through, a ridge will settle back over the area on Sunday and Monday. This should bring a return of mostly clear skies along with light and variable winds. Another trough will begin to move into the area on Tuesday, but again, it doesn't look strong enough to have any meaningful impact on air quality.
