DISCUSSION
Dense fog has developed near Tehachapi this evening, and a Dense Fog Advisory has been issued for that area until Saturday morning. Low clouds have also been forming in the Sierra to the Kern County mountains for the past couple of nights, along with patchy dense fog. Fog develops in the Central Valley later tonight, although visibility is largely 8 miles or better at the time of this writing. Latest high resolution guidance suggests fog and low clouds have a moderate probability to redevelop in the San Joaquin Valley tomorrow night into Sunday morning, or at a 30-40 percent chance of visibility at one quarter mile or less. As for the mountain areas, confidence is markedly lower, or at a 20 percent probability or lower. Above average temperatures will last until Sunday, with the warmest locations topping 80 degrees across the region, but confined generally to Kern County by Sunday.

Precipitation chances begin in the Sierra Nevada and adjacent foothills Sunday evening and last until Monday. Snow levels remain at 7,000 to 8,000 feet during this period, with the higher levels towards Sunday night into Monday morning before lowering by the afternoon. Precipitation amounts remain at 0.10 to 0.25 inch for areas from Yosemite to Fresno County and less than 0.10 inch to the south. There is a slight chance for light snow over the Sierra, mainly towards Yosemite, during Wednesday night into Thursday morning. Otherwise, expect little or no precipitation beyond early next week along with seasonably cool temperatures.

Latest CPC outlooks continue to show the odds tilted towards above average temperatures and below average precipitation for both the 6-10 and 8-14 day periods.
