.DISCUSSION...
The San Joaquin Valley saw dense fog once again this morning,
with widespread dense fog at a quarter mile visibility or less
throughout much of the valley. Due to the trough passing through
northern California, chances of valley fog tonight into tomorrow
morning drop significantly, with only a 10-20 percent chance of
northern areas seeing visibilities lower than a quarter mile.
This trough will bring light snow to the highest elevations of
the Sierra Nevada today through tomorrow afternoon, with Tioga
Pass and Tuolumne Meadows having a 10-20 percent chance of 4
inches or more of snow while the rest of the northern Sierra
could see a dusting.

A stronger trough will dip further south and into our forecast
area, making our Christmas Eve a wet one. As of right now model
ensemble guidance has precipitation starting Monday evening,
continuing through Christmas Eve, and ending very early on
Christmas morning. This storm will bring rain to much of the San
Joaquin Valley, with many areas north of Bakersfield seeing a 45
percent chance of a quarter inch of rain or more, with those
chances increasing as you go northward.

Additionally, this system will bring snow to the Sierra Nevada,
particularly above 7,000 feet. There is a 30-60 percent chance
of 8 inches of snow or more above this elevation. The timing of
this snow, which is the same as the timing with the rain, could
create an issue with holiday travel plans, so keep an eye out
for any winter headlines and plan for possible delays and road
closures in the mountains.
