Synopsis 26 738 am.

There will be scattered showers today across the region with
isolated afternoon and evening thunderstorms and a chance of
mountain snow. Conditions will be generally warmer and drier this
week though with patchy overnight and morning coastal fog most
days and a slight chance of mountain showers midweek.

Short term (tdy-tue) 26 831 am.

***update***
there have been several reports of light rain or drizzle
occurring across the forecast area this morning except for the
antelope valley. Forecast looks on track for increasing showers
this afternoon and evening as the upper low moves overhead across
interior portions of the forecast area. Showers will increase
late this morning and afternoon as the upper low moves closer to
the region this afternoon. Made minor changes to the forecast in
respect to precipitation amounts by trending down amounts slightly
through this morning. Forecast looks on track for increasing
showers this afternoon and evening as the upper low moves overhead
across interior portions of the forecast area. Slight chance for
thunderstorms remains in effect across interior locations across
all counties. 500 mb temps peak around -22 to -24 degrees celcius
late this afternoon and evening across interior locations which
should cause some marginal instability to occur. Best convective
indices remain over the ventura and western portion of l.A. County
mountains this afternoon and evening. One fly in the ointment
will be if cloud cover remains in tact over the mountains, that
thunderstorm chances could be hindered with less warming across
the surface. This will likely be the case across coast and coastal
valleys as cloud cover should remain intact hindering afternoon
convection chances and 500 mb temps are slightly warmer towards
the coast. Although there are high pops in the forecast the
actual rain totals should remain light to locally moderate overall
today except near thunderstorms where up to an inch of rain could
fall most likely across the mountains. If thunderstorms do
develop, not anticipating any flash flooding as steering winds
will be relatively fast moving from W NW to E se.

Gusty SW winds will develop across the antelope valley and la vtu
county mountains later this morning and continue through this
evening. Since there is a winter weather advisory in effect for
the l.A. And ventura county mountains which includes wind wording,
have added a wind advisory for the antelope valley from 10 am this
morning through 9 pm this evening. Expect gusty SW winds 20 to 30
mph with gusts to 45 mph. Local gust to 50 mph around lake
palmdale and adjacent mountains.

***from previous discussion***
moderate onshore flow both to the east and the north along with
lowering hgts have conspired to lift the marine layer to over 3000
feet. Marine layer stratus has developed and covers all of the
coasts and vlys and penetrates deep into the mountain passes.

A cold (for this time of year) 544 dm upper low is currently north
of the bay area. A weak impulse rotating around the low is
bringing a band of rain to the central coast. The low will also
bring just enough lift this morning to squeeze drizzle or light
rain across the coast and vlys ESP close to the foothills.

The low will spin into the monterey bay area this afternoon. This
will allow multiple PVA lobes to move through the forecast area.

This will generate numerous showers during the afternoon. There
will be enough cold air aloft this afternoon to warrant a slight
chc of tstms along the kern county line.

The upper low will make its closest approach early this evening as
the low center moves over kings county. 500 mb temps will dip to
minus 26 over northern border this will keep the threat of tstms
going this evening near the kern county line. The showers and
tstms will diminish later the evening and then end after midnight
as the low pulls to the east and NVA washes over the area.

Rainfall totals will generally be between 0.10 to 0.25 inch for
the coast and vlys, except up to 0.50 inch in some foothill areas,
and 0.25 to 0.75 inch in the mtns with local amounts up to 1.00
inch possible. Snow levels will fall to 6000 to 6500 feet, then
drop further to 4500 to 5500 feet tonight, with accumulating snow
expected over a wide area above 5000 to 5500 feet. Up to 1 inch
of snow is possible form 5000 to 6000 feet, with about 2 to 4
inches between 6000 and 6500 feet, and about 3 to 6 inches with
local higher amounts above 6500 feet. The highest peaks may see
accumulations up to 8 or 9 inches. This snow along with gusty
sub-advisory level winds will bring hazardous winter weather
conditions to the mtns and a winter weather advisory is in effect
through 300 am Monday. Please see the latest winter weather
message (laxwswlox) for further details.

Dry NW flow will bring fair skies and dry weather to southern ca
Monday.

A good eddy and onshore flow will generate a stratus deck that
will cover most of the coasts and vlys Monday night and Tuesday
morning. There should be some offshore trends later in the morning
which will help clear the stratus out and make for a sunny
afternoon.

Max temps will be below normal through the period despite a
warming trend. Today will be the coldest day with MAX temps 10 to
20 degrees blo normal (25 degrees blo normal for lancaster and
palmdale!) there should be about 5 degrees of warming on Monday
and then another 5 or so degrees on Tuesday.

Long term (wed-sat) 26 346 am.

The GFS and the ec agree in the synoptic pattern for extended
period.

On Wednesday a little trof will retrograde out from nevada. The
day will start off with a good deal of morning stratus which will
clear by late morning. The cold air associated with the trof will
produce a slight chc of tstms over the vta mtns in the afternoon.

After that dry NW flow sets up between a weak ridge to the NW and
a weak trof to the se. Not much will happen during this time there
will be varying degrees of morning marine layer stratus. More
importantly there will be a warming trend with MAX temps rising to
normal values by Thursday and then holding pretty steady through
Saturday.

Aviation 26 1203z.

At 1130z at klax, the marine layer was 3000 feet deep. The top of
the inversion was at 4100 feet with a temp of 9c. There was a
moist layer above the marine inversion up to about 6000 feet.

Widespread CIGS across just about the entire region this morning.

Conds were mostly MVFR, although there were local ifr cigs. In the
foothills and mountains, lifr to vlifr conds were widespread.

Expect these conds to cont for much of the day.

Showers will become likely this morning, continue thru the
afternoon, then end from northwest to southeast this evening. Snow
showers are expected above 6000 feet. There is a sight chance of
tstorms in the northern mtns this afternoon. Strong and gusty
southwest to west winds will affect the mountains and antelope
valley through this evening.

Conds are expected to improve toVFR in most areas this evening,
though there will likely still be some local MVFR CIGS in coastal
and valley areas, and some ifr to vlifr CIGS in the mtns.

Klax... Low to moderate confidence in taf. Conds are expected to be
mostly MVFR through this evening, then should improve to MVFR
before midnight. There is 20% chance of brief ifr conds today,
especially near showers. There is a 20-30% chance that MVFR conds
could persist through late tonight.

Kbur... Low to moderate confidence in taf. Conds are expected to
be mostly MVFR through this evening, then should improve to MVFR
before midnight. There is 20% chance of brief ifr conds today,
especially near showers. There is a 20-30% chance that MVFR conds
could persist through late tonight.

Marine 26 803 am.

For the outer waters, high confidence in current forecast.

Northwest winds will increase to small craft advisory (sca) levels
today and will remain at SCA levels through Thursday with the
occasional slight lull during the overnight hours.

For the inner waters north of point sal, moderate confidence in
current forecast. There is a 70% chance of SCA level winds today
through this evening. For Tuesday through through Thursday, there
is a 30% chance of SCA level winds each afternoon and evening.

For the inner waters south of point conception, moderate
confidence in current forecast. There is a 70% chance of sca
level winds this afternoon and evening and a 50% chance of sca
level winds Monday afternoon and evening. For Tuesday through
Thursday, winds and seas are expected to remain below SCA levels.
