.SYNOPSIS...01/120 PM.

Slightly cooler temperatures are expected Monday with some
patches of dense morning fog near the coast. Another warming
trend will kick off on Tuesday, with near record high temperatures
possible by Wednesday along with moderate Santa Ana winds.
Another more pronounced cooling trend to follow after Thursday.

&&

.SHORT TERM (TDY-WED)...01/149 PM.

Offshore flow continues to weaken this afternoon as a weak system
moves through the Pac NW. Onshore trends will continue into Monday
possibly resulting in some patchy low clouds and dense fog along
the coast south of Pt Conception. Temperatures will continue their
downward trend as well but still 5-10 degrees above normal in most
areas.

Then quickly returning back to previous programing Tue-Thu with
increasing offshore flow, gusty Santa Ana winds in the usual
areas, and unseasonably warm temperatures as much as 10-20 degrees
above normal. The hottest day will be Wednesday when highs may
touch 90 degrees across inland coast and valley areas of
LA/Ventura counties. The Santa Ana winds will have better upper
support this time, also peaking on Wednesday with gusts up to 50
mph in the mountains and 25-40 mph elsewhere in the favored
Santa Ana wind areas. Could see some isolated peaks around 60 mph
in the San Gabriel Mountains and the Santa Monicas. This Santa Ana
event also has more of an easterly trajectory to it which usually
also favors the Oxnard/Camarillo plain for gusty winds.

.LONG TERM (THU-SUN)...01/210 PM.

Another very warm Santa Ana type day on Thursday, though likely
at least a little cooler with less wind as high pressure aloft
will be shifting east as another trough approaches the Pac NW.
May still be some advisory level winds Thursday but upper support
is weakening at that point.

More pronounced cooling Friday but still at least 5-10 degrees
below normal. Beyond that there are some mixed signals in the
models. While there are still a few ensemble solutions indicating
at least a chance of some light rain by next weekend, the vast
majority push that potential into the following week around the
11th or 12th of Feb. In the meantime, it looks like the most
likely outcome for next weekend is continued dry weather with
temperatures still well above normal and possibly another light to
moderate Santa Ana wind event.

.AVIATION...01/2349Z.

At 2340Z at KLAX, there was no marine layer or inversion.

Moderate to high confidence in TAFs. There is a 40% chance of VFR
conditions through the period at KPRB. With pressure gradients
trending onshore, there is increasing confidence of LIFR
cigs/vsbys returning to coastal areas south of Point Conception
late tonight into Monday morning. For KSMO, KLAX, KLGB, KOXR,
KCMA, and KSBA there is a 20 percent chance of no cigs, but also
an equal 20 percent chance of VLIFR vsbys down to 1/4SM in fog.
Otherwise VFR conditions expected at other airfields.

KLAX...Moderate confidence in TAF. Increasing confidence of
LIFR cigs/vsbys returning late tonight or early Monday morning.
However, there is a 20 percent chance of no cigs, but also a
20 percent chance of VLIFR vsbys down to 1/4SM in fog.

KBUR...High confidence in TAF.

&&

.MARINE...01/149 PM.

For all the Outer Waters and the Inner Waters north of Point
Conception, high confidence in current forecast. From this
afternoon through Monday night, a combination of Small Craft
Advisory (SCA) level winds and seas is expected to develop. For
Tuesday through Thursday, winds and seas are expected to drop
below SCA levels, except for a 30-40% chance of SCA level
northeast winds across the nearshore waters Tuesday through
Wednesday and potentially into Thursday morning. Another round of
SCA level winds and seas across the outer waters will be possible
Friday into Saturday morning.

For the Inner Waters south of Point Conception, moderate to high
confidence in current forecast. Tonight through Monday a
moderately long-period W swell will bring seas of 4-8 feet to the
southern inner waters. Then Tuesday night through Wednesday and
potentially into Thursday morning, local areas of SCA level
northeast winds will be possible from Ventura Harbor south through
Malibu and off the coast of Orange County. Otherwise, winds and
seas will remain below SCA levels through Thursday.
