Forecast Discussion:

Low pressure moves into California today and into Nevada and Utah by Sunday. Winds pick up this afternoon and continue to be gusty throughout Saturday and into Sunday. Higher winds bring some additional background ozone into the area this afternoon allowing for Moderate AQI values. Winds increase and persist through Saturday and Sunday providing more dispersion/ventilation across the region and reducing the ozone threat on both Saturday and Sunday and allowing for Good AQI values. No precipitation is expected through the weekend. Winds subside for Monday.
