.SYNOPSIS...17/123 PM.

Skies will be partly to mostly cloudy through Friday with a
slight chance of showers through this evening. Temperatures will
remain well below normal. Warmer temperatures are expected
Saturday through the middle of next week but still 3 to 6 degrees
below normal across the coast and valleys.

&&

.SHORT TERM (TDY-SUN)...17/156 PM.

A couple of upper lows will be influencing our weather over the
next couple days but with minimal to no impacts. There have been a
few showers today mainly just in the LA mountains and foothills.
Yesterday`s deep marine layer has evolved into a 9000" moist layer
but there`s not enough upward motion or moisture at lower layers
to get precip much below 3000 feet elevation. Still can`t rule out
a brief shower through this evening but again mostly at higher
elevations. Otherwise just a lot of clouds and cooler than normal
temperatures. And breezy conditions again across the Antelope
Valley with gusts between 30-45 mph, strongest where Hwy 14 and
the AV meet near Lake Palmdale.

The second upper low is just moving into far northeast Nevada this
afternoon. This is quite a bit farther east than the models had
advertised earlier this week. Due to this eastward adjustment rain
chances have dropped to under 10% for Friday in most areas except
the far eastern San Gabriels near Wrightwood where there could be
just enough moisture and instability to generate a brief shower
in the afternoon. Otherwise, likely still a lot of clouds in the
morning before clearing in the afternoon with temperatures still
below normal.

Weak high pressure will develop behind that for the weekend along
with much weaker onshore flow leading to a 10-15 degree increase
in high temperatures for the valleys and interior areas and 3-5
degrees of warming near the coast. This will bring highs to near
normal for the valleys and interior but still slightly below
normal for the coast. Uncertain about marine layer coverage but a
lower marine inversion may take at least until Sunday to develop
when weak troughing returns along the west coast.

.LONG TERM (MON-THU)...17/302 AM.

Good agreement with the deterministic and ensemble mdls for the
extended fcst. A series of trofs will move through the PACNW and
will bring weak, but dry, cyclonic flow over the Srn CA. Onshore
flow will increase as well and the night through morning low
cloud pattern will return to the coasts and probably the lower
vlys. Skies otherwise will be mostly clear. Moderate to strong
onshore flow in the afternoon will bring gusty winds to the mtns
and Antelope vly. Temperatures will not change too much each day
with a few degrees of warming Sun and Mon followed by a few
degrees of cooling Tue/Wed. Monday will be the warmest day of the
next 7 with plenty of 70s across the csts and vlys except for 60s
at the beaches.

.AVIATION...17/2345Z.

At 2251Z at KLAX, there was a 6500 ft deep moist layer.

Overall, moderate confidence in 00Z TAF Package. VFR cigs >030-070
with periods of MVFR possible for all terminals except KPMD and
KWJF (low chance). There is a 20-30% chance for night through
morning MVFR cigs north of Point Conception.

KLAX...High confidence in 00Z TAF. Best chances for MVFR cigs
BKN/OVC015-025 from 08Z to 18Z Fri. No significant east wind
component is expected.

KBUR...High confidence in 00Z TAF. There could be periods of MVFR
cigs BKN/OVC015-025 thru 18Z Fri.

&&

.MARINE...17/1247 PM.

For the Outer Waters, moderate to high confidence in current
forecast. Through Friday, high confidence in winds and seas
remaining below Small Craft Advisory (SCA) levels. For Monday
into Tuesday, there is a 30-50% chance of SCA level winds.

For the Inner Waters north of Point Sal, high confidence in
current forecast as winds and seas are expected to remain below
SCA levels through Tuesday.

For the Inner Waters south of Point Conception, high confidence in
current forecast as winds and seas are expected to remain below
SCA levels through Tuesday.
