Forecast Discussion:

High pressure is building over the region today and its position will cause breezy easterly winds this afternoon and into tomorrow morning. This will likely increase PM10 levels a little, but we don't expect concentrations to be high enough to lift it out of the Good AQI range. Then, with calmer conditions on Sunday, particulate levels should drop down a little further into the Good range. Light afternoon breezes are expected Monday and Tuesday as a low pressure system begins to move down the west coast and into our region. These winds may again increase PM10 a little, but we do expect it to remain in the Good range. Overall, all pollutants are forecast to remain in the Good AQI range through the forecast period.
