Synopsis 21 1237 pm.

Low pressure will keep cool temperatures and chances of
intermittent showers over the area into memorial day weekend.

Today into tonight will be windy, and showers should be limited to
the mountains and north of ventura. By Thursday, the mountains
and southern areas have a slight chance of showers. Friday looks
mostly dry.

Short term (tdy-fri) 21 151 pm.

A series of troughs will keep a cool, unsettled weather pattern
going through early next week. The first one will come through
later tonight into Wednesday morning. It's taking an "inside"
track so it doesn't have a lot of moisture to work with but
there's pretty good cold air and energy aloft with it that showers
are a good bet at least across our interior areas bordering kern
county from southeast slo county to northwest la county and also
along the central coast as well. North to northwest flow will tend
to weaken and dissipate these showers as they move south over the
ridges of the transverse ranges and around pt conception but
areas near the foothills and the southwestern portion of sb county
could see some light showers Wednesday morning. Amounts expected
to be generally a quarter inch or less, except locally higher
across northern ventura county. Snow is expected to fall at
unusually low elevations for this time of year, reaching as low as
5000' with a mixture of rain and snow possible as low as 4500'
early Wednesday. Impacts pretty minimal as accumulations are
expected to remain above the major pass levels and generally under
3 inches.

By Wednesday afternoon most of the precip should be east and south
of the area but cool and breezy conditions expected again with
highs mostly in the 60s at lower elevations.

Models showing a weaker impulse coming through Thursday and
there's enough low level moisture and south to southwest flow for
a chance of light showers especially up against the foothills of
ventura and la counties. Otherwise just another cool day but not
as breezy.

On Friday the trough remains over the area but weakens and the air
mass dries out a little before the next system over the weekend.

As a result Friday is expected to be the "warmest" day of the next
several with plenty of sunshine and light winds but temps still a
few degrees below normal.

Long term (sat-tue) 21 157 pm.

Models are showing another upper low dropping south along the west
coast Saturday. It should bring a return to damp weather to the
area by Saturday night or Sunday but possibly as early as Saturday
afternoon north of pt conception. Since the low is semi-cutoff by
Sunday it will be very slow moving and will keep a threat of
precip across the area, especially the southern portion Sunday
night into early Monday. Low confidence in timing and amounts at
this point but most of the solutions, including the ensembles keep
rain totals under a half inch through Monday. This one isn't quite
as cold as the system tonight and Wednesday but snow levels could
fall to as low as 6000' or so.

Aviation 21 1901z.

At 1800z, there was no marine inversion at klax, but there was a
moist layer up to around 6000 feet.

Low to moderate confidence in 18z TAF package. Deep moist layer
will bring general bkn-ovc skies to most sites with flight
categories varying between MVFR andVFR. Confidence in timing of flight category
changes is low.Some coastal sites will have sct skies andVFR
conditions, however with pretty strong gusty winds in the
afternoon. Strong gusty winds are also expected in the antelope
valley, along with possible MVFR vsbys in blowing dust or sand at
kwjf kpmd through this afternoon.

Klax... Low confidence in 18z taf. Timing of change from MVFR to
vfr CIGS is low confidence as flight categories will vary through
21z. For tonight, there is a 20% chance of MVFR cigs. Strong west
winds (gusting up to 30 kt) are possible 18z-04z.

Kbur... Low confidence in 18z taf. Timing of change from MVFR to
vfr CIGS is low confidence as flight categories will vary through
21z. For tonight, there is a 20% chance of MVFR cigs.

Marine 21 147 pm.

For the outer waters, moderate to high confidence in current
forecast. High forecast in winds remaining at small craft
advisory (sca) levels through Wednesday night with a 70% chance of
gale force winds this afternoon tonight across pzz673 676.

Additionally, seas will remain at SCA levels through Wednesday.

On Thursday, there is a 40% chance of SCA level winds. On Friday
and Saturday, winds and seas are expected to remain below sca
levels.

For the inner waters north of point sal, high confidence in
current forecast. Winds will increase to SCA levels this afternoon
and remain at SCA levels through Wednesday night. Additionally,
seas will build to SCA levels today and Wednesday. For Thursday
through Saturday, winds and seas are expected to remain below sca
levels.

For the inner waters south of point conception, moderate to high
confidence in current forecast. High confidence in winds remaining
at SCA levels today through Wednesday night with a 60% chance of
gale force winds this afternoon tonight. Through Wednesday night,
the strongest winds will occur across western sections. For
Thursday through Saturday, winds and seas are expected to remain
below SCA levels.

Beaches 21 147 pm.

Another northwest swell will bring high surf advisory conditions
to the west and northwest facing beaches on the central coast
from late tonight through Wednesday night.

A combination of gale force winds in the southern california
bight and increased northwest oceanic swells will increase the
breakers enough for elevated surf and a beach hazards statement
for west facing beaches of la ventura counties tonight through
Wednesday night.

Despite the decreasing surf conditions, strong and dangerous rip
currents will persist along area beaches.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
