Moderate onshore flow will continue through early Sunday with winds strengthening further Sunday night into Monday. 25 to 30 kt northwest wind gusts are likely on Monday along with steep seas of 10 feet or greater...resulting in conditions hazardous to small craft.

927 pm pdt Sat mar 25 2017

Synopsis
A low pressure trough passing to the north will bring more clouds,
gusty winds, and isolated showers through late this evening. A
repeat performance is expected on Monday as another system passes by
just to the north. Just a little precipitation is expected from both
systems. A break between the two should ensure fair and dry
conditions on Sunday. Strong winds are possible across the mountains
and deserts from Monday afternoon through Tuesday morning as the
second system digs southeast across arizona. Dry and warmer after
Monday under a weak high pressure ridge aloft. Later in the week, a
stronger storm system could impact the region but confidence is low
regarding impact.

Discussion For extreme southwestern california including orange...

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

Evening update...

cool and mostly cloudy conditions this evening with a few showers
redeveloping in the brisk NW flow in the wake of a weak upper level
trough that is now moving through arizona. These showers are very
small but have produced a few reports of measurable rain along the
coast. Expect the showers to flare up for the next couple of hours
and then dissipate after midnight. Some weak ridging should ensure
Sunday is mild and dry. Another weak upper level trough will bring
another chance of showers on Monday and cooler conditions with a
renewed deeper marine layer and strong onshore winds. No significant
updates were made this evening to the ongoing forecast database.

Previous forecast discussion issued at 111 pm pdt...

satellite imagery at 1 pm pdt still indicated extensive cloud cover
offshore, over the ca bight, drifting east. Echoes had diminished on
nws radar though. Farther east, clouds were scattered to broken
along and west of the mts with mostly clear skies over the deserts.

Surface pressure gradients were running 5-6 mbs onshore to the
deserts with a modest onshore trend. Peak westerly wind gusts were 35
to 45 mph in wind-prone desert pass areas, with more widespread and
20 to 25 mph gusts across the deserts.

Isolated showers are possible through this evening, especially along
the coastal slopes, otherwise, it will be partly cloudy with winds
subsiding overnight in the mts/deserts.

A weak low pressure trough will be moving east tonight, followed by
weak ridging aloft on Sunday. This will bring fair and slightly
warmer weather on Sunday, after morning marine clouds clear, with
light winds. Another trough will follow on Monday and looks like it
will be strengthening as it passes into az Mon night. This could
result in strong west to northerly winds over the mts and deserts
from late Mon into early tue. The models are developing a few light
showers as well, however they should mainly affect the coastal
slopes of the mts, and little accumulation is expected.

Current indications from our hires WRF are winds will increase over
the mts/deserts on Monday, peak late Monday and Monday night, then
slowly decrease on Tue morning. Peak wind gusts of 65 to 75 mph are
possible over sparsely populated northeast sections of the coachella
valley early Tue morning, but gusts to around 60 mph look possible
below the cajon pass as well Tue morning. These are wind-prone areas
so impacts are questionable, but blowing dust and sudden cross winds
could pose a significant hazard for travelers through the desert mon
night/tue. A high wind warning and/or advisory will likely be
needed for these areas.

Another weak ridge is forecast to build SE across ca on tue/wed with
fair skies, lighter winds and warmer days. Following the ridge will
be another digging short-wave trough. This one has proved to be
problematic for numerous model runs now. The track has been flip-
flopping with some model runs suggesting stronger digging to the sw.

This could bring light precip to the region and very strong onshore
winds across the coastal waters, mts/deserts thu/thu night. It would
also be much cooler than currently forecast on fri. Before
suggesting any impact this storm may have across socal, more
consistent model performance is needed to build confidence.

Aviation
260400z... Multiple low cloud bases, ranging from 1700-4500 ft msl,
will continue overnight mainly over and west of the mountains. An
isolated -shra is possible this evening, however confidence is
increasing that most areas will remain dry. Vis will lower to 1 sm
or less where low clouds near higher terrain.VFR conditions are
expected by late Sun morning.

Marine
West-northwest wind gusts near 20 kt will continue through this
evening over portions of the outer waters. Northwest winds will
restrengthen Sunday night through early Tuesday as another system
passes across the region. Gusts to 25-30 kt are possible late
Monday, in addition to combined seas rising to near or above 10 ft.

This will likely result in hazardous conditions for small craft
Monday through early Tuesday. Conditions improve late Tuesday.

Beaches
West-northwest swells from around 285-290 degrees will create
elevated surf of 3-6 feet Sunday through most of next week. This
will be accompanied by an increased risk of strong rip currents
through the period.

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