Area forecast discussion, Dec 29, 3:34 PM PST, 4 hours 28 minutes before
Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
334 PM PST Sun Dec 29 2019
.SYNOPSIS...29/307 PM.
Rain, mountain snow, and gusty winds will move into the region
through Monday, lingering into early Tuesday in some locations.
There will be gusty northeast winds on Tuesday that will be
strongest over portions of Ventura and Los Angeles Counties. New
Years Day will be breezy but dry.
&&
.SHORT TERM (TDY-WED)...29/228 PM.
Clouds on the increase this afternoon ahead of the next pacific
storm system which is currently centered off the coast of Northern
California. As of 2 pm, doppler radar already showing the leading
edge of shower activity moving into Monterey County, and will be
arriving this evening across SLO County.
All models continue to agree that a 549 DM upper low will rapidly
move down the Central Coast waters about 100 miles from the coast.
It will start out west of the Bay Area this evening and will be
near Pt Conception by dawn. As the upper low approaches the
Central Coast tonight, there will likely be fairly widespread rain
developing across SLO and SBA counties during the overnight hours
into early Monday morning. While the core of the upper low will
remain offshore of the Central Coast, the proximity of the cold
air aloft will bring increasing instability to the Central Coast.
This along with precipitable water values between 0.75-0.90 inches
and increasing upper level diffluence will bring the threat of
brief heavy downpours and a slight chance of thunderstorms to the
Central Coast overnight, although the best threat of thunderstorms
will remain over the adjacent coastal waters. Latest model
guidance showing the potential for a large spread of precipitation
totals for SLO/SBA counties, generally ranging between 0.25 and
1.00 inches, with the higher amount likely focused over the
Central Coast. Peak hourly rates are expected to range between
0.10 and 0.50 inches per hour for SLO/SBA counties, with the
higher rates likely favored over the Central Coast. A winter
weather advisory will be in effect for the SBA county mountains
later this evening into Monday, where 4 to 8 inches of snow is
expected above 5000 feet, with lighter accumulations possibly down
to 4000 feet.
The latest NAM/GFS models continue to track the upper low almost
due south on Monday away from our coast, and eventually tracking
it eastward into northern baja late Monday night. This track will
maintain the best instability, moisture, and dynamics over the
coastal waters, with less rainfall projected for Ventura and LA
counties. In fact, this track will bring increasing offshore flow
to Ventura and LA counties, which will add to the low level drying
for these areas. At this point, the best chance of any showers
for LA/Ventura counties appears to be late tonight through Monday
morning, but amounts are generally expected to remain less than
0.25 inches. The one exception to this could be the Ventura County
mountains which could see locally higher QPF amounts, mainly in
the form of snow. Despite the southerly track of this system, the
northeast low level flow is expected to bring some wrap around
moisture into the Antelope Valley and interior mountains of LA
county on Monday, with rapidly lowering snow levels down to 2500
feet in these areas. As a result, we could see some minor snow
accumulations in the LA County mountains, foothills of the
Antelope Valley, and possibly the Antelope Valley floor. Have
added winter weather advisories for the Ventura and LA county
mountains for later tonight into Monday. While snow accumulations
are not overly impressive (2-4 inches for Ventura mountains, 1-3
inches for LA mountains), there could still be significant impacts
with accumulating snow and strong winds affecting some of the
lower passes, including Interstate 5 near the Grapevine and Hwy 33
in the Ventura mountains. Highways 14 and 138 could also see some
minor snow accumulations in the foothills of the Antelope Valley.
The other concern for Monday will be the increasing offshore winds
across LA/Ventura counties with continued gusty offshore winds
into Tuesday. Wind gusts of 35 to 50 mph will be likely for the
most wind prone coastal/valley areas, with local gusts up to 60
mph across the LA county mountains. The winds in the mountains are
handled by the winter weather advisories in the short term, but
the remaining wind prone coastal and valley areas will likely need
wind advisories for this event. There is a good chance of these
gusty offshore winds reaching Avalon Harbor due to the cooler
nature of this wind event.
New Year's Day is shaping up to be nice, with dry and mild
conditions, with weakening offshore winds during the day.
.LONG TERM (THU-SUN)...29/233 PM.
Dry northwest flow will set up over the state, keeping Southwest
California rain free during the extended period. Northerly winds
will be on the increase Wednesday night into Thursday.
Heights are expected to rise to 584-586 DM Friday through Sunday.
The rising heights combined with some offshore flow near the
surface will bring a warming trend to the region, with highs
potentially climbing above 70 degrees in some coastal/valley
areas by next weekend.
&&
.AVIATION...29/2333Z.
At 2315Z, there was no marine layer or marine inversion at KLAX.
Overall, low to moderate confidence in 00Z TAFs. High confidence
in rain this evening and overnight north of Point Conception with
low confidence in timing of flight category changes (conditions
varying between MVFR and IFR). For sites south of Point Conception,
low to moderate confidence in rain and low confidence in timing
of flight category changes (conditions will vary between MVFR and
VFR levels). There is a slight chance of TSTMs 02Z-12Z for sites
across Santa Barbara and San Luis Obispo counties.
Gusty northeast winds will develop Monday morning with LLWS/turbulence
likely through and below passes and canyons. Additionally,
easterly winds will likely impact KLAX.
KLAX...Low confidence in 00Z TAF. Low confidence in timing of
light showers and MVFR CIGs overnight (there is a 30% chance that
showers will not develop and CIGs remain at VFR levels). Moderate
confidence in easterly winds 8-10 knots 12Z-23Z.
KBUR...Low confidence in 00Z TAF. Low confidence in timing of
light showers and MVFR CIGs overnight (there is a 30% chance that
showers will not develop and CIGs remain at VFR levels). Moderate
confidence in northeast wind surfacing after 16Z with LLWS and
turbulence possible.
&&
.MARINE...29/114 PM.
Moderate-to-high confidence in the current forecast. Winds and
seas will likely remain below Small Craft Advisory (SCA) levels
through late tonight, then east to northeast winds will increase
to SCA levels between late tonight and Monday as a storm system
moves into the region. Hazardous seas will likely develop across
the inner waters inside the southern California bight Monday
afternoon and Monday night. There is a 30 percent chance of gale
force gusts nearshore between Rincon Point and Pacific Palisades.
Northeast winds and hazardous seas will likely create significant
problems in east facing harbors, such as Avalon Harbor and Two
Harbors on Catalina Island. SCA level winds and local wind-driven
seas will likely continue through Tuesday morning or Tuesday
afternoon, then hazardous seas will build from north to south,
highest west of the Channel Islands.
Seas will build to hazardous levels across the outer and northern
waters for an extended period of this week, possibly into Friday.
There is a 50 percent chance that seas may reach SCA levels
across portions of the inner waters inside the southern California
bight Thursday and Thursday night.
SCA level winds are likely to redevelop again across the northern
and outer waters between Wednesday and Thursday night.
Isolated thunderstorms are possible across the outer and northern
waters tonight and into Monday. Any thunderstorms that form may
produce local wind gusts to 40 knots, rough seas, dangerous
lightning, heavy rainfall with reduced visibility, and
waterspouts.
&&
.BEACHES...29/110 PM.
An extended period of high surf is possible much of this week.
Surf is expected to develop Monday night along the Central Coast,
then spread south into Ventura County beaches on Tuesday. There is
a chance that Los Angeles County beaches could see high surf
develop, as well. Strong rip currents are likely.
The surf will subside somewhat for Tuesday night and Wednesday,
then there is a better chance of higher surf at all beaches for
Wednesday night through Friday. A longer period swell will likely
arrive on Wednesday night, peak Thursday and Thursday night, then
subside through Friday. While there is still much uncertainty,
there is a chance that local damaging sets could develop at
Central Coast beaches.
&&
