.KEY MESSAGES...

1. Fog, while dense at times, and low clouds will continue each
night and morning across the San Joaquin Valley into the
foothills up to 1,500 feet through Tuesday.

2. Above average temperatures will continue across the
mountains and desert until Tuesday, as the high pressure
pattern persists over the region.

3. Precipitation makes its return to Central California by the
middle of the week after having a dry start to December.

&&

.DISCUSSION...
The consistent stable pattern over the southwest will continue
through at least the beginning of next week, with strong ridging
keeping the low stratus clouds in place for the center of the San
Joaquin Valley with dense fog on the edge of the Valley from
elevations of 500 feet to 1500 feet. This stratus will also
lower further down during the nighttime hours and lead to fog in
the Valley itself.

A small pattern change is likely in store for Central
California, with the ridging over the Southwest weakening
somewhat as a small trough passes through the Pacific Northwest.
This weaking may lead to slight troughing in Northern California
into Central California, which may lead to a small amount of
precipitation for the northern-most Counties in our CWA, mainly
in Mariposa County and Yosemite Nation Park. This small
disturbance may also provide elevated winds aloft to break the
inversion over the Valley and lead to the stratus deck clearing
out, though it`s unclear if those winds will be strong enough.

The next potential system is expected to move through the region
by Friday afternoon into the weekend, with most long term
ensemble models, including the Euro, GFS and Canadian, all
indicating precipitation from the next weekend onwards into day
14 on the 28th of December. This kind of agreement shows a
confidence form these ensembles that precipitation may occur,
even if the amount is not agreed upon just yet. This time period
will be watched closely for consistency over model runs, which
would strengthen the confidence in that forecast.
