What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis 24 340 am.

Low pressure moving across the eastern pacific will push into
central california Saturday. Skies will generally be mostly
cloudy through early Saturday, except partly cloudy in the
antelope valley. There is a chance of showers north of point
conception tonight and Friday, with patchy night through morning
drizzle elsewhere. It will be quite cool through Friday, then
there will be a warming trend this weekend into early next week.

Short term (tdy-sat) 24 406 am.

Very deep marine layer across the region again early this morning,
and the depth has risen to 5000 feet. With the deep marine layer
and some cyclonic low level flow, there could be some patchy
drizzle this morning, especially in the foothills. Models show
plenty of moisture lingering, so expect skies to remain mostly
cloudy west of the mountains today. If there is any clearing, it
would mostly likely be across the coastal plain. MAX temps will be
down across most of the region today, with temps as much as 10 to
15 degrees below normal in the valleys. Gusty winds will affect
the mtns and antelope valley this afternoon and evening, but will
probably remain below advisory levels.

A sharpening upper trough in the eastern pacific will evolve into
an upper low about 400 nm west of pt conception later this
morning. This low will drift eastward, and be centered about 100
nm west of monterey by late tonight, while taking on somewhat of a
negative tilt as it does so. Some upper level diffluence and
decent low and mid level lift should be sufficient to produce at
least isolated shower activity north of pt conception late
tonight and fri. Elsewhere, deep moisture and strongly cyclonic
flow will likely allow for patchy drizzle late tonight Fri morning
from the coastal slopes west and south. Have left pops out of the
forecast for now, but a case could certainly be made for some
slight chance pops, especially in the foothills of l.A. County.

Skies will likely remain mostly cloudy west of the mountains again
on fri. MAX temps will change little on fri, except there will be
several degrees of cooling in the mountains and antelope valley.

Gusty winds in the mtns and antelope valley may get close to
advisory levels Fri afternoon and evening.

The upper low will move across central ca Fri night and early sat
Saturday, with a trough extending southward into the forecast
area. Expect the marine layer to remain very deep, but a weakening
inversion could make for a more ragged cloud field. Still, there
should be a fair amount of night through morning clouds in coastal
and valley areas. There could still be some patchy drizzle in
coastal and valley areas of l.A. And vtu counties. Developing n-s
gradients Fri night should bring some gusty winds to the santa
ynez range and adjacent south coast of sba county Fri night, which
could keep skies clear there, or at least delay clouds until morning.

Expect better clearing on Sat as the trough axis moves east of the
region in the afternoon. North to south offshore gradients will
continue to sharpen, and there should be gusty northwest to north
winds across southern sba county and the i-5 corridor late sat
into Sat night. MAX temps will likely be up a few degrees in most
areas on sat, but should still be below normal, except possibly
across the south coast of sba county due to downsloping northerly
flow.

Long term (sun-wed) 24 421 am.

The upper low will move eastward into northern utah on Sunday,
then will move very little thru mon. Height rises and weakening
onshore flow should allow for a warming trend Sun and mon, with
somewhat of a decrease in coverage and inland extent of the night
thru morning low clouds and fog. By Mon and tue, MAX temps should
be near or a bit above normal, especially across the interior.

However, latest models keep some weak troughing across the region,
with a very weak upper low forming just west of the area by tue.

This may have the affect of keeping MAX temps down a bit, but
heights will be fairly high. A more significant trough will
approach the pacific wed, bringing cooling to the region.

Aviation 24 1314z.

At 1238z, the marine layer depth was around 4300 feet deep at
klax. The top of the inversion was around 4800 feet with a
temperature near 12 degrees celsius. The marine layer is expected
to deepen to around 5000 ft.

Moderate-to-high confidence in the current forecast. Highest
confidence in MVFR conditions at coastal and valley terminals
through much of today. MVFR CIGS will becomeVFR in many
locations. Moderate confidence that valley TAF sites will stay
cloudy most of the day with a 40% chance for some clearing across
coastal sites S of point conception this afternoon.

Klax... MVFR conditions will persist through this morning and
likely becomeVFR late this morning or early afternoon hours.

There is a 40% chance that there will be some clearing by mid
afternoon.

Kbur... MVFR conditions will persist through most of this morning
then becomeVFR and likely linger through much of the day.

Marine 24 244 am.

For the outer waters, high confidence in the current forecast.

Winds and seas will remain below small craft advisory levels
through at least Friday. There is a 60 percent chance of small
craft advisory level northwest winds across the southern portion
of the outer waters from point conception to san nicolas island
from Friday night through Sunday. Confidence is somewhat lower
for advisory level gusts for the northern portion of the outer
waters from Saturday afternoon through Sunday.

For the inner waters, generally high confidence in the current
forecast. For the waters north of point sal, winds and seas will
remain below SCA levels through Monday, except for a 40 percent
chance of SCA level winds Saturday night.

For the waters south of point conception, winds and seas will
remain below SCA levels through Friday. For Friday night through
Sunday, there is a 60 percent chance of SCA level winds at times,
especially across western sections of pzz650.

A long period southerly swell will continue to move through the
coastal waters through early Friday. Locally rough conditions may
occur at local harbor entrances, especially those with southerly
exposure.

Lox watches warnings advisories
Ca... Beach hazards statement in effect through this evening for
zones 40-41-87. (see laxcfwlox).

Pz... None.

Hazard potential outlook (sat-wed)
Advisory level sundowner winds are possible for western portions
of the sb south coast this weekend.

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.
