Synopsis
A series of weak low pressure systems will bring showers this
evening, Saturday night and again Sunday. The coldest and
strongest of these systems will be on Sunday with widespread
showers and snow levels as low as 3500 feet. Monday and Tuesday
will be dry but cold. More precipitation is possible Wednesday
afternoon through Friday.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

as we take a breath from the copious rains and strong winds of
the past two days, we are greeted by three layers of clouds this
morning. Ground fog had visibility near zero for some areas of the
valleys. Stratocumulus clouds at two to three thousand feet are
out as well, and those produced a few showers only a few hours
ago. Then there are the high clouds way up there, hinting at the
next wave of precipitation coming down the coast for later today.

A broad trough of low pressure continues over the west coast and
embedded shortwaves rotating within this trough will continue to
bring episodes of precipitation and wind this weekend. Wave
number one arrives this afternoon and evening. Precipitation
amounts a tenth to a quarter inch in the lowlands, and up to about
a half inch in the mountains. Snow level drops to 4,500 feet. On
late Saturday wave number two arrives but less than a quarter
inch is expected and snow level down to 4,000 feet or so. On
Sunday wave number three is actually the final lobe of the massive
trough, a cold front that has more energy and an even lower snow
level. Amounts will be a quarter to a half inch for most areas,
and maybe up to one inch in the mountains of san diego county. All
three waves will come in northwest flow, which favors san diego
county for harvesting the most precip. Total snowfall through the
weekend will accumulate above 4,000 feet with about a foot at
bases of ski resorts and up to about 20 inches above 9,000 feet.

Strong winds will be mostly on ridgetops and adjacent desert
slopes where top gusts at the windiest spots will exceed 60 mph.

Monday and Tuesday promise fair and dry weather, but rather chilly
behind Sunday's cold front in cold northerly flow. The big western
trough never GOES away and it develops the next trough to come
down the west coast during the middle of the week. Of course
there is less certainty for timing and precip amounts, but it
looks cold for more showers and mountain snow. It could arrive
Wednesday or Thursday.

Aviation
151630z... Isolated -shra will develop today, with local bkn-ovc cigs
2000-3000 ft msl. Patchy 1-3 sm and local 1 4 sm vis will continue
in the valleys through mid-morning. Otherwise, sct-bkn clouds 4000-
7000 ft msl through the period. Shra will become more widespread
this evening with CIGS lowering to 2000-2500 ft msl and vis 2-4 sm
in heavier showers. Terrain will be obscured at times.

Marine
West-northwest winds will increase early Saturday morning and
continue through Monday morning, with strongest gusts to 30 kt
possible Saturday and Sunday evenings. A combination of steep wind
waves and a mix of westerly swells will result in choppy seas. A
small craft advisory is in effect from 2 am Saturday through 10 am
Monday. Winds and waves will lower through the day Monday.

Beaches
Elevated surf of 3 to 6 ft will continue through Saturday due to a
short period west swell from 260 degrees. A new west-northwest swell
of around 10-12 ft 8-9 sec from 290 degrees will generate larger
surf late Saturday into Sunday, mainly in southern san diego county
where sets of around 8 ft possible. A beach hazards statement
remains in effect for the elevated surf and strong rip currents
through Sunday afternoon.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.
