Forecast Discussion: After a couple days of Good ozone levels, we expect to move back up into the Moderate category due to winds shifting out of the west. Wind will be breezy today and tomorrow though so we don't expect ozone to increase too much. However, with lighter winds on Sunday and Monday, we forecast ozone levels to increase into the mid Moderates. On Tuesday, winds are forecast to once again shift to a southerly direction which should lower ozone.

As for PM10, today and tomorrow are the days to watch. The breezy winds associated with a trough moving through may kick up a little dust. We don't expect winds to be strong enough for any major dust issues, but we do expect PM10 to reach Moderate levels today and tomorrow. By Sunday PM10 should drop back into the Good range with the lighter winds and remain there through the rest of the forecast period.
