DISCUSSION
Another foggy morning is currently taking place in the San Joaquin Valley. Expect partial clearing at most valley locations this afternoon with a return to dense fog by early this evening or around sunset. Latest high resolution model guidance shows the probability for visibility below 1/4 mile in the valley is near 100 percent once again from late tonight until late Monday morning. Elsewhere, above average daytime temperatures will continue, although the chances for highs in the 70s in the Kern County desert and Sierra Nevada foothills are about 25-35 percent for the next couple days. High pressure will remain in control for the next several days.

This high pressure pattern along with the valley fog will last until next weekend with minor changes in temperatures. Latest CPC outlooks continue to favor above average temperatures for both the 6-10 day and 8-14 day periods. A slight tilt in the odds (33-40 percent chance) towards below average precipitation continues for the 6-10 day period, but shifts to towards above average precipitation for the 8-14 day periods. Perhaps we'll see a pattern change, including some precipitation, sometime next week.
