Dec 5 to Dec 10 A low-pressure system over the central coast will continue to provide a mix of sun and some potential light rain on Monday to Tuesday with clear skies Wednesday as the system moves on to the east. Late this week there is some more potential for some mixed sun and rain from Thursday into the weekend. Temperatures may drop below freezing at night and reach highs in the 50s during the daytime. Because airflow is expected to be consistent, AQI for Ozone, PM2.5, and PM10 are expected to be GOOD during this time.
