The ridge of high pressure that has persisted over the West Coast will begin to break down starting Wednesday as a weak trough embedded within the ridge approaches the West Coast. As it does so, expect gradual cooling from Wednesday into Friday or Saturday, as well as afternoon breezes and increasing high clouds. On Saturday night to Sunday a cold front is expected to move across the state, bringing further cooling, with breezes strengthening and shifting from southwesterly to westerly, with a slight chance of light rain showers. No significant precipitation is expected for at least the next 10 days.

We may see temperatures dropping well into the 30s in some areas on Monday morning before high pressure rebuilds and temperatures warm back up into the upper 70s or low 80s during the first half of next week.
