.SYNOPSIS...04/650 PM.

Breezy Santa Ana Winds will continue to taper off through late this
evening, with sub advisory northerly winds continuing into Friday
morning across mountain areas. Freezing conditions will occur
across some interior areas Friday morning. A significant warming
trend will begin this weekend with temperatures well above normal
through next Thursday, peaking next Tuesday and Wednesday.

.SHORT TERM (THU-SUN)...04/850 PM.

***UPDATE***

Offshore winds are diminishing across the area this evening, with
many sites shifting from northeast to a more northerly direction.
A couple of standouts in the Santa Monica Mountains are still
gusting 30 to 40 mph but most sites in the Santa Ana wind corridor
are gusting 15 to 25 mph as of 700 PM. Winds may pick up again for
a few hours later tonight, but should begin to weaken more
substantially between 800 to 1000 AM Friday morning.

Clear skies are expected for most areas tonight, except for the
Salinas Valley where light winds may allow for another night of
dense fog for a few hours after midnight through around 900 AM.
However, there is a chance the fog will not materialize, making
this a lower confidence forecast.

Chilly overnight temperatures are expected across the area
tonight thanks to efficient radiational cooling, in particular
the wind sheltered interior valleys, including the Antelope
Valley. See below for details on the Freeze Warnings in effect for
tonight. A Frost Advisory was added for the Ojai Valley based on
last night`s low of 32 degrees and similar to slightly warmer lows
expected there tonight.

***From Previous Discussion***

Another chilly night is on tap. The coasts and coastal valleys,
especially south of Point Conception, will cool a couple degrees
as the weakening offshore winds have less of downslope warming
affect on these areas. This will likely be the last night that
Frost/Freeze products will be needed for the forecast period. The
Freeze Watch for the Antelope Valley, southern Salinas Valley, and
Interior San Luis Obispo County valleys has been converted to a
Freeze Warning. The Freeze Warning is somewhat marginal for the
southern Salinas Valley, with temperatures likely in the 30-35
degree range. Higher confidence in widespread freezing
temperatures across the Antelope Valley and interior SLO County
valleys tonight with lows in the 25-32 degree range common.

High temperatures will be anything but remarkable into Saturday,
with some minor fluctuations day to day. Weaker offshore flow and
eventually weak onshore flow Friday and Saturday afternoons will
lead to a few degrees of cooling at the coasts though. Highs
across coastal valleys will yo-yo a degree or two here and there
through Saturday, depending on how far inland the marine influence
makes it. Interior portions including the Antelope Valley will
see the largest increase in temps, where an increase up to 10
degrees over the next couple of days will be common.

A significant warming trend will begin Sunday as a very powerful
(for this time of year) ridge overhead builds across the West
Coast, sending most of the coastal valleys into the 70s, while
the coasts and interior valleys will top out in the mid to high
60s.

.LONG TERM (MON-THU)...04/153 PM.

Focus will shift to high temperatures next week as Monday through
Thursday are looking very warm for this time of year. The upper
level ridge will be fully parked along the west coast, with the
highest 500 mb heights just off of the Central California coast.
Over Southwest California, 500 mb heights will likely reach the
95th-97th percentile during this period. In addition to the
synoptic pattern favoring a warm and dry spell, offshore winds
will increase from the east and particularly the north Monday and
Tuesday, with northerly flow continuing into Thursday. As of right
now, the most likely outcome would be weak to occasionally
moderate north-northeast winds.

Temperatures will be 10 to 15 and locally 20 degrees above normal
through Thursday except for 5 to 10 degrees above normal near the
coasts. Widespread upper 70s to at least low 80s will be common
across coastal valleys, while coasts will likely top out in the
low to mid 70s. Mid 80`s cannot be ruled out for warmest valley
locations. There is considerable agreement amongst ensembles
that the ridge will persist through the work week, but begin to
break down into more zonal flow over the weekend. It might be a
good idea to keep those winter coats in the closet next week.

.AVIATION...05/0249Z.

At 2353Z at KLAX, there was no marine layer or inversion.

High confidence in the current forecast, except low-to-moderate
confidence for KPRB. There is a 40% chance that low clouds will
not form over the site and conds remain VFR tonight at KPRB.

Periods of moderate low- level wind shear will be possible over
the mountains for the overnight period.

KLAX...High confidence in the 00Z TAF. There is a 20% chance of
east wind component between 6-8 kt from 05Z-15Z Fri.

KBUR...High confidence in the 00Z TAF.

&&

.MARINE...04/118 PM.

Across the Outer Waters, Small Craft Advisory (SCA) level winds
are likely from Friday afternoon through late Saturday,
especially north of the Channel Islands. There is a 50% chance
that SCA winds may persist through Sunday and Monday.

For the Inner Waters, there is a 30 percent chance of SCA winds
briefly returning tonight through Friday morning for Rincon Point
to Santa Monica and into the San Pedro Channel. Nearshore north of
Point Sal, there is a 20-40% chance of SCA winds during the
afternoons/evenings Friday through Monday. Otherwise, winds and
seas will likely remain below SCA levels through the weekend.
