Marine Weather and Tides
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 22 921 am.
An upper level trough continues to move east of california
bringing a continued onshore flow and below normal temperatures
throughout the week. Night to morning low clouds will continue
through Friday for the coast and valley areas.
Short term (tdy-thu) 22 923 am.
a deep marine layer remains entrenched across coastal and valley
areas through to the coastal lower slopes. Low clouds were present
for all areas except across much of the sba south coast south to
the channel islands. Locally gusty southwest winds continue across
the foothills of the antelope valley near lake palmdale this
morning. Local advisory strength onshore winds are likely again
this afternoon into early evening across this area. Agree with the
previous thinking that a reverse clearing scenario south of point
conception is the most likely scenario for today but by no means a
slam dunk. Forecast is in good shape and will be issuing an update
to tweak low clouds, namely to remove low clouds sba south coast
and adjacent waters where they have failed to form.
***from previous discussion***
sort of an easy three day forecast with relentless may grey
stratus, but there will likely be a few little surprises each day
as the marine layer clouds react to slightly different forces.
The marine layer is so deep right now (4800 feet) that is
qualifies more as a moist layer rather than a marine layer. The
capping inversion is very weak. This will likely but not for
certain lead to a reverse clearing pattern with the vlys staying
clouds and the coasts clearing or at least tuning from cloudy to
partly cloudy. Not much lift but still cannot rule out a little
drizzle near the i-210 corridor. One thing is for sure... It will
be cool with lower than normal hgts and onshore flow conspiring
with the deep moist layer. MAX temps will be 6 to 8 degrees blo
Onshore flow will increase Wednesday. There will be dry SW flow
aloft. There does not look like the inversion will lower or
strengthen so expect a similar cloudy morning and reverse clearing
Very strong onshore flow (9-10mb) develops Thursday ahead of an
approaching cut off low. Wind advisory level gusts will occur in
the antelope vly and the stratus will have a hard time clearing.
Max temps will continue 6 to 8 degrees blo normal.
Long term (fri-mon) 22 255 am.
The ec and the GFS are back in agreement about the handling of the
east pac cut off low. Both mdls move it to the bay area by Friday
afternoon and open it up into a trof. The trof is then forecast to
move over nv where it entrains a little energy from the a pac nw
trof and cuts off into a closed low again Saturday evening. This
low then spins around the nv ut area Sunday and Monday.
The upper low over the bay area on Friday will bring a trof to slo
and sba counties in the morning and very strong onshore flow
behind it. The lift from the trof will bring a deep marine layer
to the area and perhaps some drizzle as well. The ec hints at a
shower or two for the central coast but will have to see some run
to run consistency there before thinking about adding it to the
Very strong onshore flow will likely bring advisory level gusts to
the antelope vly in the afternoon and then a moderate sundowner to
the sba south coast in the evening. This sundowner should be
strong enough clear the stratus away from the south coast.|
The difference in this solution is that the ridge that was
forecast for the weekend and early next week is now much weaker.
The big change will be the decrease in onshore flow and to a
lesser extent the steady rise in hgts.
The night through morning stratus pattern will shrink slowly and
clearing will be earlier and more complete.
Max temps will slowly rise and could reach normal by Sunday and
then if all GOES as planned exceed normal on Monday. If downtown
la does in fact exceed its normal MAX temp next Monday it would
end a streak of 17 consecutive below normal MAX temps days.
Aviation 22 1728z.
At 17z, there is a weak marine inversion at klax based at 4200
feet. The top of the inversion was 5400 feet with a temperature
of 12 degrees celsius.
Overall, moderate confidence in coastal valley tafs and high
confidence in desert tafs. The trends in the marine inversion will
be lowering through tonight with a shallower layer that is likely
to burn off quicker Wednesday morning. Lingering MVFR CIGS for
portions of the central coast and valleys south of pt conception
this afternoon with some sct between 22-04z. MVFR CIGS with patchy
ifr likely to return after 06z for all coastal and valley tafs.
Klax... Moderate confidence in 18z taf. BknVFR conditions through
21z then sct-bkn from 21-06z. MVFR CIGS are likely to return
07-17z Wednesday with a 20% chance of ifr CIGS occurring.
Kbur... Moderate confidence in 18z taf. BknVFR conditions through
06z then MVFR CIGS are likely to return 07-17z Wednesday with a
50% chance of ifr CIGS occurring.
Marine 22 840 am.
For the outer waters, high confidence in current forecast. Winds
and seas will remain below small craft advisory (sca) levels
through Thursday. On Friday and Saturday, there is a 70% chance of
sca level northwest winds. There will be a mixed swell with
shorter periods from the NW and long periods from the s.
For the inner waters, moderate to high confidence in current
forecast. For the waters north of point sal, winds and seas will
remain below SCA levels through Thursday then there is a 60%
chance of SCA level winds each afternoon evening on Friday and
Saturday. For the waters south of point conception, winds and seas
will remain below SCA levels through Thursday. On Friday and
Saturday, there is a 50% chance of SCA level winds, especially
across western sections.
A long period southerly swell will continue to move into the
coastal waters today and continue through Thursday. 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 Thursday evening
for zones 40-41-87. (see laxcfwlox).
Hazard potential outlook (thu-mon)
Strong rip currents and elevated surf will linger at south-facing
beaches across los angeles and ventura counties.
