AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1248 PM PST Thu Feb 16 2017
.SYNOPSIS...
Rain across San Luis Obispo County will sag southward today to
all of southwestern California by evening. Heavy rain and strong
winds will impact the entire region on Friday and taper off early
Saturday. Scattered showers will linger through Sunday ahead of
another system moving into the region on Monday.
&&
.SHORT TERM...(TDY-SUN)
So here we go with the start of what looks to be an impressive
period of rain and wind across our area. This initial band will
remain fairly benign with just light amounts of precip through
this evening. The rain is currently as far south as the Santa
Barbara area and will continue trekking southeast into Ventura and
LA Counties later today and this evening.
Precip will ramp up in intensity later tonight into Friday as the
next upper low that's still a good 1000 nm west of the Bay Area
this afternoon gets closer. At the same time a 987mb surface low
will move into the coastal waters tightening up the surface
gradient and kicking up a strong east to southeast wind. Strongest
winds will be at higher elevations and high wind watches will be
converted to warnings this afternoon. For lower elevations wind
advisories will be in effect all day Friday before decreasing in
the evening as the gradients weaken. While the surface winds do
have a decidedly east component to them, the winds just off the
surface will veer rapidly to the south and southwest providing a
strong orographic component to help enhance precip rates south of
the transverse ranges from SB to LA Counties. With pwats in the
1-1.4" range the combination of the upslope effects, good energy
and difluence aloft it should be a very efficient precip producer.
Models have been fairly consistent with this, though the NAM did
tack backwards slightly on the amounts. But see no reason to
make any significant changes to the forecast at this time.
Rainfall rates peaking around 1 inch per hour still seem
reasonable. Thunderstorm chances don't look great initially but
better later Friday into Saturday as the upper low moves into the
area with colder more unstable air.
Overall rain rates expected to start tapering off Friday night
with just showers and possible thunderstorms Saturday, though best
chances for storms would be over the mtns. Rain amounts Saturday
really variable, but overall not too excessive except where
thunderstorms occur. Mostly a quarter inch or less.
Snow levels will start out around 6000' then rise to around 8000
Friday night when that warmer plume of moisture moves through,
then dropping back down to 6000 or slightly lower Saturday with
the colder air arriving.
Sunday looks dry in most areas with plenty of sunshine but some
lingering clouds over the mountains and possibly some increasing
stratocu across the valleys in the afternoon.
.LONG TERM...(MON-THU)
Weak ridging will develop Monday while a storm tries to push
through from the west. Models have been struggling with this one
going back and forth on the strength. The GFS today was a little
stronger than yesterday but the ECMWF is still pretty weak. Hard
to see too much from this given the position of the ridge aloft so
will keep pops as they are but amounts will likely be a quarter
inch or less most areas.
Low confidence forecast continues Tue-Thu. A series of weak
systems will move through associated with a fairly deep upper
trough along the west coast. Not seeing much moisture with any of
these systems but enough to warrant at least some rain chances
each day until we closer and can refine the forecast and get a
better idea on timing. Temps should remain below normal through
the period.

.AVIATION...16/1800Z.
At 17Z, there was an inversion at KLAX at around 700 ft deep. The
top of the inversion was around 1800 ft with a temperature of
17C.
Moderate confidence on general timing and flight categories
through Friday, but will likely have randomly changing CIGS, VIS,
and winds with the upcoming strong storm. Forecast reflects
middle road, most common conditions...with a chance of being
occasionally worse.
KLAX...Moderate confidence in general thinking, but likely will
see flight cats vary a lot after 12Z. High confidence in strong
SE winds on Friday, with an 07-12Z onset window of going above 10
KT. Heaviest rain and lowest flight cats expected 20-03Z Fri...with
CIGS likely down to 008-012, VIS down to 1/2-2SM, and SE gusts
25-35KT.
KBUR...High confidence in VFR conditions through at least 06Z.
Moderate confidence in general thinking after than, but likely
will see flight cats vary a lot after 12Z. Heaviest rain and
lowest flight cats expected 20-03Z Fri...with CIGS likely down to
008-012, VIS down to 1/2-2SM, and SE gusts 20-30KT.
&&
.MARINE...16/100 PM.
...Very Dangerous Conditions Late Tonight through Friday...
A very dangerous storm system will bring strong SE winds, very
steep seas, low visibility due to rain, and thunderstorms to the
area on Friday. High confidence in widespread strong Gale Force
SE Winds on Friday, with a 30 percent chance of exceeding Storm
Force (48 KT). Channels and passages between islands will likely
see locally enhanced winds. This is a dangerous situation, as such
winds will create very steep seas exceeding 10 feet. These winds
will weaken significantly Friday night but steep seas will likely
linger. Gusty NW winds should form quickly NW of San Nicolas
Island Saturday night and Sunday. High confidence in a moderately
large west to northwest long period swell building in Saturday and
Sunday as well...which will create dangerous breaking waves near
shore.
Moderate confidence of thunderstorms forming over the coastal
waters Friday afternoon through Saturday...but confidence is low
in terms of timing and severity.
