AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
147 PM PST Tue Jan 10 2017

.SYNOPSIS...
Precipitation chances will increase tonight into Wednesday, then
again Wednesday night through Thursday as a couple more low
pressure systems move across the region. Snow levels will lower
to mountain passes by Thursday afternoon with showers lingering
into Friday. Warming and drying is then likely this weekend.

&&

.SHORT TERM...(TDY-FRI)

Main weather concerns will be two storm systems to impact the
region late tonight to Wednesday and another Thursday into Friday
morning. Already seeing light rain across all four counties mainly
from coasts to foothills with a few hundredths each hour. This is
due to a continued moist westerly flow over southwest California
in advance of a cold front stretched across northern sections of
the state this afternoon. Steady rain has been occurring from SFO
Bay northward. As this system sags south tonight, rain will
increase over SLO/SBA Counties along with southwest winds. Rain
rates could reach 0.40 inch/hr as this system moves through
with most areas seeing 0.20-0.33 inch/hr rates. Not anticipating a
need for flash flood watches as would expect only minor mud and
debris flows from burn scars with these rates. Widespread rain
will give everyone 0.5-1 inch rain totals through Wednesday
morning with the steadier rain ending over LA County by late
morning. Foothills and northwest SLO Co. are likely to see
rainfall totals between 1-3 inches. Snow levels well above 8k feet
so no significant mountain snow issues. Gusty southwest winds
will reach advisory levels for SLO County valleys and all
mountains and Antelope Valley tonight through about midday
tomorrow.

Scattered rain showers are forecast for Wednesday afternoon with
temperatures remaining below normal. A closed low pressure system
will form over western Oregon and bring another fast-moving cold
front to southwest California by daybreak on Thursday. This system
will be the coldest of the week and is taking a more over-water
trajectory, therefore plenty of moisture to work with. The main
rain band with this one will be apparent Thursday morning along
the central coast and south of Pt Conception from midday Thursday
foward. Rainfall totals look similar to Wednesday's storm, right in
the 0.5-1.5 inch amounts, but it will be more showery in nature
overall. The main issue is the very cold air aloft at -25 to -28
degrees C late Thursday afternoon into the night. Snow levels
likely to be about 5k feet during steadier precipitation Thursday
then drop less than 3k feet by Friday morning. Snow showers are
likely to continue into Friday afternoon for mountains and this
could be a major impact to highway passes including the I-5
Grapevine, highway 14, and highway 33. In addition, unstable air
could generate graupel showers for valleys and coasts as the
center of the upper low moves directly over our region Thursday
night into Friday morning. Temperatures will be stuck in the 50s
for highs both Thursday and Friday.

.LONG TERM...(SAT-TUE)

Cool northerly flow and weak trough passage expected on Saturday,
but it looks dry. Stronger high pressure ridging will build over
the state on Sunday and Monday for warmer conditions. The ridge
seems to flatten out across the northern part of the state by
Tuesday as a storm system moves across the Pacific Northwest
states. Will have to see if this storm track starts to sag
southward later next week, but for now it will remain dry through
Wednesday with above normal temperatures.

&&

.AVIATION...10/1800Z.

At 1800Z at KLAX...There is no marine layer.

Extremely low confidence in the 18z TAF package. Occasional light
rain or drizzle will periodically drop the MVFR conditions to IFR
or LIFR at a moments notice. Frequent changes in ceilings and
visibility will continue for the next 24 hours.

KLAX... Low confidence in the 18z TAF. Timing of the
precipitation and of lowered CIGs/VSBYs are the primary
uncertainties. Precipitation will begin with drizzle in the
afternoon then light to moderate precipitation will develop in the
evening and overnight.

KBUR... Low confidence in the 18z TAF. Timing of the
precipitation and of lowered CIGs/VSBYs are the primary
uncertainties. Precipitation will begin with drizzle midday then
light to moderate precipitation will develop in the evening and
overnight.

&&

.MARINE...10/200 PM.

Increasing southerly winds today ahead of another frontal system
approaching the region. This system will move across the coastal
waters tonight and tomorrow and winds will likely reach advisory
levels in the northern outer waters during this period. A large
northwest swell arrives on Wednesday and may require a Small Craft
Advisory for Hazardous Seas...particularly over the northern
coastal waters.

&&

.LOX WATCHES/WARNINGS/ADVISORIES...
CA...Wind Advisory in effect until 7 AM PST Wednesday for zone
 37. (See LAXNPWLOX).
 Beach Hazards Statement in effect through Thursday morning for
 zones 40-41. (See LAXCFWLOX).

 (See LAXNPWLOX).
PZ...Small Craft Advisory in effect until 3 AM PST Wednesday for
 zones 645-670-673. (See LAXMWWLOX).

&&

.HAZARD POTENTIAL OUTLOOK...(FRI-TUE)
Friday there will be low snow levels and lingering impacts to
mountain travel. No significant hazards expected Saturday through
Tuesday.
