Summary: A strong low is moving into the Pacific Northwest. The associated cold front is moving through northern California with light showers as far south as a Bay Area/Sacramento line. Upper level high pressure over central and southern California will effectively maintain dry weather for the valley as the thrust of this system is eastward and not southeastward.
The flow pattern for the remainder of the week will be generally out of the west, maintaining above average temperatures each day unless the fog completely takes over, in which case daytime highs would actually run marginally below average. Dew points this afternoon are in the mid to upper 40s, so if we observe several hours of generally clear skies tonight, fog and low clouds will have no problem developing.
The next major change in the pattern will occur during the second half of the weekend. Models are aligned a bit better this afternoon in a trough of low pressure moving through California Sunday and Sunday night. if you average out model information, the southern limit of precipitation is roughly over the Kern County mountains, so the chance for light precipitation for the valley Sunday and Sunday night seems reasonably good.
After this system moves through, a strong ridge of upper level high pressure will build over the eastern Pacific and into much of the western United States for what promises to be several days of dry weather with the main weather culprits being night and morning fog and low clouds.
Forecast: Mostly to partly cloudy tonight with areas of fog and low clouds developing after midnight. Mostly clear to occasionally partly cloudy Wednesday through Saturday with widespread night and morning fog and low clouds. Increasing cloudiness Saturday night. a good chance of light showers Sunday and Sunday night. a slight chance of light showers Monday morning, otherwise Monday and Monday night will be mostly to partly cloudy. Areas of fog and low clouds Tuesday morning. becoming mostly clear in the afternoon.

Winds: Winds will be at or less than 6 MPH through Friday with periods of near calm conditions.
Rain: Dry weather will continue through at least Saturday evening. There is a slight chance of showers before sunrise Sunday morning. that chance of light showers will increase Sunday through Sunday night as a relatively weak trough of low pressure moves through. This far out, it’s difficult to pinpoint rainfall amounts, but at this point it doesn’t appear to be a significant event. There’s a small chance of a few showers lasting into Monday morning. if models are accurate at all, it looks like Monday and the next week or will be dry.
Frost Discussion: All locations will be above 32 degrees tonight and each night for the remainder of the week and, if models are correct, well into next week, as well.
