Synopsis 26 818 pm.

Scattered showers, isolated thunderstorms and snow over the
mountains are possible through this evening, as low pressure
system moves across the area. A warming trend is expected to start
tomorrow through at least Friday. Night through morning clouds
are expected to return to most coastal areas by Tuesday. There is
a slight chance of mountains showers by midweek.

Short term (sun-wed) 26 852 pm.

***update***
temps were very chilly across southwestern ca today, with many
record low MAX temps set, including 62 degrees at downtown l.A.

(old record 63 set in 1947 and 1918). Highs averaged 6-12 deg
below normal for coastal areas, and 15-25 deg below normal for the
vlys, mtns and deserts.

An unusually strong for late may 550 dm h5 upper level low was
centered over the central san joaquin valley early this evening.

This system is forecast to push off to the SE overnight and reach
the ca nv border just W of las vegas by dawn.

Scattered showers lingered early this evening across the forecast
area but should start to diminish and be confined mainly to the
mountains and eastern l.A. County by midnight with some clearing
skies expected especially for the coast and vlys, altho some low
clouds may persist on the central coast.

Snow showers will be possible in the mtns above about 5000 feet
overnight, and possibly down to 4500 ft. An inch or two of
additional accumulation cannot be ruled out for the l.A vtu
county mtns. The snow and gusty winds will continue the winter
weather advisory for this area until late tonight. Please see the
latest winter weather message (laxwswlox) for further details.

Overall storm rainfall totals are expected to remain generally
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
mountains. Snow levels will fall to 4500 to 5500 feet tonight,
with accumulating snow expected above 5000 to 5500 feet. Storm
total snow accumulations should be up to 1 inch from 5000 to 6000
feet, with about 2 to 4 inches between 6000 and 6500 feet, and
possibly as much as 3 to 6 inches with local higher amounts above
6500 to 7000 feet. Impacts are not likely for the i-5 corridor
through Monday morning.

***from previous discussion***
the upper low will eject out towards the four corners region
on Monday, leaving dry NW flow aloft and weaker onshore flow
across the lower levels. Being a little pessimistic with cloud
wording on Monday with partly cloudy skies, but could be mostly
sunny by the afternoon across coast and valleys, with some
lingering clouds across the mountains and antelope valley Monday.

By Tuesday, an upper level disturbance within the northerly flow
will move quickly through the area which should at the least bring
some afternoon stratocu to the mountains. The best chance for
storms to fire up will be to the north across hanford NWS area.

With the upper flow from the north, there is the scenario for some
showers over the san joaquin valley to move into the area late
Tuesday afternoon, but confidence is not high to justify showers
at this time, but will continue to monitor. Both the NAM and gfs
are indicating a slight chance of thunderstorms across interior
sections. Another shortwave pushes through and enough cooling
aloft to initiate possible thunderstorms Wednesday afternoon and
early evening across interior sections. If isolated thunderstorms
do initiate they could drift slowly to the south. Not much in the
way of mid level moisture to work with, but most unstable CAPE is
fairly impressive to around 700 j kg across the mountains.

As far as temperatures, there will be some widespread warming 3-8
degrees over the forecast area on memorial day, but high temps
will remain 5-8 degrees below normal for this time of year. Each
day will bring a few degrees of additional warming to around
normal by Wednesday for most areas. Although onshore flow will be
a bit weaker Monday through Wednesday, onshore will continue to
bring night through morning low clouds to coast and some coastal
valleys through the period.

Long term (thu-sun) 26 248 pm.

The GFS and the ec models continue to agree on large scale
features for the upper level pattern with a broad upper trough
remaining across the west. This will bring continued near normal
or slightly cooler than normal high temperatures. At the lower
levels, a persistent onshore pattern will continue allowing for
night through morning low clouds and patchy fog to continue across
most coast and coastal valleys.

Aviation 27 0013z.

At 2345z, there was no marine inversion at klax.

Overall, moderate confidence in 00z TAF package. GenerallyVFR
conditions will prevail at the airfields thru Mon afternoon,
except for possible MVFR CIGS at times through early this evening
especially with any showers that pass through. Confidence in
timing of flight category changes fromVFR to MVFR and back is
moderate at best.

Gusty W winds will affect koxr and kcma through early this
evening, and for kpmd and kwjf thru the TAF period.

Klax..Moderate confidence in the 00z taf. GenerallyVFR
conditions will prevail thru Mon evening, except for a 20%-30%
chance of MVFR CIGS at times through early this evening
especially with any showers that pass through.

Kbur... Moderate confidence in the 00z taf. MVFR CIGS are expected
thru 02z this evening, otherwiseVFR conditions will prevail thru
mon afternoon, except for a 20%-30% chance of MVFR CIGS at times
02z-06z this evening especially with any showers that pass
through.

Marine 26 817 pm.

For the outer waters, high confidence in current forecast.

Northwest winds will increase to small craft advisory (sca) levels
at times tonight for the southern waters zone (pzz676) and for all
the outer waters Monday through Friday with the occasional slight
lull during the overnight hours.

For the inner waters north of point sal, moderate confidence in
current forecast. Winds should remain below SCA levels tonight.

There is a 50% chance of SCA level winds each afternoon Monday and
Tuesday. For Wednesday through Friday, winds and seas are
expected to remain below SCA levels.

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
