.SYNOPSIS...14/128 PM.

Well above normal temperatures will continue in most areas through
next week. The next chance of rain will be the week of Christmas.

&&

.SHORT TERM (SUN-WED)...14/815 PM.

Another day of well above normal temperatures for all areas except
the coast where morning fog, cool ocean temps, and light onshore
flow kept highs in the 60s. Current satellite imagery showing
low clouds and fog returning this evening across the Central
Coast and portions of the LA county coast. As heights build and
the offshore flow strengthens overnight, looking for the marine
layer depth to become more shallow. As a result, any fog that does
form will have the potential to go dense, possibly requiring
some dense fog advisory issuances overnight.

Another warm up is on the way starting Monday as high pressure
builds into California and another weak Santa Ana wind event
develops. Not expecting advisory level winds as upper support is
almost nil but some gusts of 25 to 35 mph are likely in the
mountains and some of the valleys. Between the building high and
downslope warming from the offshore flow temperatures will warm up
quite a bit, especially at the coast. Overall, most areas will be
in the 70s and 80s which is 10-15 degrees above normal.
Humidities will be lowering as well with most areas between 10
and 20 percent during the afternoon.

Not a lot of change Tuesday and Wednesday, though gradients to
the north will be increasing which should generate some increasing
north winds through the Santa Ynez Range and the I5 corridor.
Temperatures will remain well above normal. May see a little bit
of cooling at the immediate coast as gradients start to trend
onshore.

.LONG TERM (THU-SUN)...14/224 PM.

Dry weather still expected through at least next weekend, however,
models continue to advertise at least one storm coming through on
or just before Christmas. There remains a fair amount of spread in
terms of arrival time and amounts, which is to be expected for a
storm that is still around 10 days out. Likely not a big snow
producer locally as the system is tapping into moisture coming in
from the southwest.

.MARINE...14/957 PM.

For the Outer Waters, moderate to high confidence in current
forecast. Winds were somewhat stronger than forecast, therefore
the start time of the Small Craft Advisory (SCA) was moved up to
tonight for PZZ673. SCA level winds expected to become more widespread
by late Monday afternoon. These conditions are likely to persist
through the work week. The waters from near Point Conception down
to San Nicolas and westward about 40 NM will see the worst
conditions. There is a 20% chance of low- end Gale force wind
gusts on Wednesday in this area. Seas may approach 10 ft across
the western portion of PZZ676 during this time.

For the Inner Waters north of Point Sal, moderate to high
confidence in current forecast. High confidence in winds & seas
remaining below SCA levels through Monday morning. SCA level wind
gusts are possible to likely beyond 5 NM south of Port San luis.
From Tuesday through Thursday, there is a 30% chance of SCA level
winds during the afternoon and evening hours.

For the Inner Waters south of Point Conception, high confidence
in winds and seas remaining below SCA levels through Monday.
From Tuesday through Thursday, there is a moderate chance of SCA
level winds across the western half of the Santa Barbara Channel.
Winds should be strongest and most widespread Wednesday with a
moderate chance of impacting eastern portions. High confidence
in winds and seas remaining below SCA levels elsewhere.
