.DISCUSSION...
High temperatures across the San Joaquin Valley on Friday were
generally around 7 to 12 degrees above climatological averages
for this time of the year. This was due to an upper ridge of
high pressure along with strong low level warm air advection
ahead of the approaching system. This warming was most evident
in the southern SJ Valley due to downsloping flow. Bakersfield
was 80 degrees on Friday, which was 16 degrees above average
and tied the record high for the date.

Precipitation has overspread much of the district north of Kern
County as of this writing. Rainfall amounts have generally been
around one third to one half of an inch thus far across mainly
Merced, Mariposa, and Madera Counties. The snow level is near
6500 feet around Yosemite NP rising up to around 7000 feet near
Sequoia NP. The moisture plume is currently located along the
central CA coast with radar imagery showing strong orographic
enhancement as it reaches the Sierra. Precipitation will shift
south through the morning with high resolution guidance keeping
showers going mainly across the mountains through the afternoon
and into the evening.

Ensembles keep the deep upper low spinning just off the Pacific
Northwest coast through Tuesday. Precipitation looks to take a
break across central CA on Sunday with just a few light showers
generally. Ensemble members focus on Monday for the next round
of moderate to heavy precipitation. This activity looks to last
into Tuesday as the upper low finally fills and shifts inland.
Ensembles indicate a short wave ridge may shift over central CA
on Thanksgiving for a dry day. But they also show a weak upper
low just upstream that brushes the coast with precipitation on
the day after.
