AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1254 AM PST Thu Jan 19 2017

.SYNOPSIS...
A series of storms will bring rain and mountain snow, heavy at
times, a slight chance of thunderstorms, and strong, gusty
southerly winds to southwestern California through early next
week. The first storm will affect the area tonight into Thursday.
The second weather system can be expected Friday into early
Saturday. The third storm is expected late Saturday night into
early Monday, which should bring the heaviest precipitation
amounts. Temperatures will be below normal across the area into
next week.

&&

.SHORT TERM...(TDY-SAT)

A weak warm frontal boundary brought some light rain to the area
this afternoon and this evening. The warm frontal band put around
a tenth of an inch in the gage for most areas with some higher
totals in the San Luis Obispo County foothills. The cold front
sits north of the area this evening, stretching from the Bay Area
southwest out to near 30N and 130W. The front will push southeast
quickly tonight. Models solutions indicate the best instability
moving quickly from northwest to southeast between 10 pm this
evening and 8 am early Thursday morning. Rainfall will increase in
areal coverage and intensity later tonight as the stronger
dynamics arrive with the system and interact with the orographic
lift. A 500 mb cold pocket near -25 degrees Celsius brushes the
area, bringing the potential for isolated thunderstorms on late
tonight and Thursday morning. 700 mb temperatures cool to near -8
degrees Celsius in the latest model solutions which should drop
the snow level to between 4500 and 5000 feet on Thursday. Locally
the snow level could drop to around 4000 feet in heavier snow
showers. For those planning to travel on the Grapevine Thursday,
the Tejon Pass could be impacted heavier snow showers at times.
The forecast will update to reflect the change in snow levels,
otherwise snow totals between 5 and 10 inches of snow seems
reasonable above 7000 feet.

*** FROM PREVIOUS DISCUSSION ***

Rain and snow should taper off pretty rapidly Thursday morning
with mainly just some lingering afternoon showers over the higher
terrain. The second system will start bringing rain to NW SLO
County late Thursday night and to the remainder of the area
Friday, tapering off Friday afternoon and evening. The low lvl
southerly winds are a bit stronger with this second one and model
qpf is a quarter to half inch higher which makes sense. Once again
model instability wasn't super impressive but certainly enough to
warrant a slight chance of thunderstorms across the area Friday.
This will likely require another flash flood watch for the burn
areas. Rain and snow amounts expected to be slightly higher with
this second system.

Winds at low levels and aloft shift to the west Friday afternoon
and northwest Friday night which should help shower coverage
diminish, especially at lower elevations south of Pt Conception.
Additional drying and low lvl subsidence should keep most of the
area dry Saturday except for possibly some isolated showers over
the mountains and Central Coast. A cool and breezy day however
with lower elevations mostly in the 50s to low 60s.

.LONG TERM...(SUN-WED)

The biggest change in the models today came with the timing of the
third system, which had been pegged for a late Sunday through
early Monday arrival. However, today's runs have sped that up a
good 12 hours, so now most of Sunday looks wet with the heaviest
period in the morning up north and late afternoon and evening in
LA County. There's also a considerable spread in the models with
precip amounts. The operational GFS is by far the outlier, a good
2" higher than the ensemble mean as well as the ECMWF. So while
confidence is high in a decent rain event Sunday, not real
confident on the amounts. The ensemble mean and ECMWF would
support a rain event that is similar to the previous two storms.
But if the operational GFS prediction of 50-60kt south winds at
850 comes to fruition then certainly the higher amounts would be
more likely. The GFS is also showing higher pwats with this
system, around 1.4" Sunday, which is up a good half inch from the
two earlier storms.

This also leads to considerable uncertainty with snow levels as
the GFS is tapping into a much warmer subtropical air mass and
freezing levels rise to over 10000'. The other models keep the
snow level fairly similar as before but with less moisture to work
with. So low confidence on the details with storm #3.

Much colder air is expected to arrive Monday, though here again
significant model differences are leading to lower confidence in
amounts. Snow level should drop to at least 4000' Monday, perhaps
as low as 3000' as thicknesses drop to around 531dm. The ECMWF is
the more aggressive model here pushing through a 4th and colder
system Monday that could lead to some additional heavy rain and
snow into Monday evening.

Most areas should start drying out Tuesday as northerly flow takes
over. Still quite cool through about Wednesday then warming up
later in the week.

.AVIATION...19/0610Z.

Frontal system will sweep quickly through the region overnight,
reaching the Central Coast just after midnight, and the Los
Angeles Basin by mid morning. This front will bring widespread
MVFR cigs and moderate to heavy rain, with locally embedded IFR
conds. In the mountains and foothills, there will be widespread
LIFR to VLIFR conds through noon Thu. There is a slight chance of
tstms near the front. There will be a period of gusty southeast
winds ahead of and with the front, followed by gusty west winds.
Conds will improve to high MVFR to VFR in most areas by Thu
afternoon, but the threat of showers will linger through the
evening.

KLAX...Moderate confidence in the 06Z TAF. Expect widespread MVFR
conditions to develop by 12Z, with a 20 to 30 percent chance this
will occur as early as 09z. There is a 30 percent chance of IFR
conds between 12z and 17z.

Expect gusty southeast winds to develop, rising to 12 to 15 knots
by 12z. There is a 30 percent chance that will occur as early as
09z. There is a 20 percent chance that SE wind gusts could reach
25 to 30 knots at KLAX between 12z and 18z. There is a 20 percent
chance of tstms between 12z and 17z.

KBUR...Moderate confidence in the 06Z TAF. Expect widespread MVFR
conditions to develop by 12Z, with a 20 to 30 percent chance this
will occur as early as 09z. There is a 30 percent chance of IFR
conds between 12z and 17z.

Expect gusty southeast winds to develop, rising above 15 knots by
12z or so. There is a 30 percent chance that will occur as early
as 09z. There is a 20 percent chance that SE wind gusts could
reach 30 knots at KBUR between 12z and 18z. There is a 20 percent
chance of tstms between 12z and 17z.

&&

.MARINE...18/900 PM.

Southeast to south winds will continue to increase tonight across all
coastal waters ahead of a cold front. Gales are forecast for the
coastal waters northwest of the Channel Islands through early
Thursday morning. Winds will turn to the west and diminish some
between early Thursday morning and Thursday evening. There is a 40
percent chance that small craft advisory headlines may need to be
extended into Thursday night. Winds will increase again early
Friday across the entire coastal waters and remain elevated
through at least Saturday. A gale watch remains in effect for the
entire coastal waters from early Friday morning through Saturday
night. There is a slight chance of thunderstorms tonight into
Thursday and again on Friday.

A large long period swell will build across the coastal waters
through Thursday, then continue to build to very large levels
Friday night into Saturday. The swell will likely reach heights
of more than 20 feet over the northern outer waters late Friday
night into Saturday. West-to-northwest facing bays and harbors
may be impacted by the swell over the next coming days,
especially Morro Bay and Ventura Harbors.

.HAZARD POTENTIAL OUTLOOK...(SAT-WED)
For Saturday, very large and potentially damaging surf will likely
impact west-facing beaches. Minor coastal flooding is also
possible Saturday morning. There could also be some lingering
mountain snow showers on Saturday morning, with potential impacts
on the Interstate 5 corridor going over the Grapevine.

Another storm system will impact the region late Saturday night
through Monday. Potential impacts include flash flooding and
debris flows for the burn areas, urban and small stream flooding,
rock slides along canyons roads, downed trees and isolated power
outages, significant travel delays, and dangerous winter driving
conditions in the mountains.
