.KEY MESSAGES...
1. Dense Fog Advisory issued for the San Joaquin Valley valid
through 1 PM Thursday due to persistent chances for fog each
night and morning through that timeframe.

2. Temperatures near to just below season averages through the
week.

3. Indications for back-to-back dry low pressure systems sliding
in over the weekend to end the month and Tuesday into Wednesday
to begin December.

.DISCUSSION...
Stratus lingered around again yesterday which helped keep
things cool. This was due to the ridge of high pressure over the
West Coast. The stratus is anticipated to break today due to
warmer temperatures with the higher cloud deck and the change
over the weekend. Yet, we have a 70 to 95 percent chance of
highs of at least 60 degrees for most of the Valley in the NBM.

However, latest model ensembles have changed as a shortwave
trough that has been monitored the past few days remains weak in
the latest runs and goes over the Rockies instead. However, two
new troughs are of note. The first one is a faster moving
trough to the west of the ridge which will cutoff early Friday
before shifting well south and parks itself between Hawaii and
Baja California. At the same time, a new shortwave slides in
from Alaska on Saturday as an inside slider through Sunday into
Monday. However, the models continue to back off with any
precipitation as there is now a less than 10 percent chance of
any rain in the Valley and even a 20 percent or less chance of
any snow accumulation.

The ensembles have another shortwave trough sliding down Tuesday
into Wednesday. Both have it being an inside slider but the
precip chances are still low with this one as it will have a
drier flow from Alaska and interior Canada than from the Gulf of
Alaska or the Central Pacific.

IFR to MVFR ceilings and visibilities will persist in most
Valley locations through 18Z Thursday. After 18Z, conditions
