Marine Weather and Tides
Lomita, CA

Version 3.4
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 21 311 am.

Cool conditions will continue through the week with areas of
drizzle this morning across the coasts and adjacent valleys of
ventura and los angeles counties. There is a slight chance of
thunderstorms this afternoon and evening in the los angeles...

ventura... And eastern santa barbara county mountains. Temperatures
will warm slightly through the week.

Short term (tdy-wed) 21 300 am.

The marine layer is 3500 feet deep and low clouds cover the coasts
and vlys and extend into the coastal slopes. A late season cut off
low with a 564 dm core is over slo county and the lift assoc with
this low will help squeeze out a little drizzle in the vcnty of
the foothills and cstl slopes.

500 mb temps around -16 deg c will accompany the upper level low.

This along the afternoon sunshine will bring some instability
(li's of -3 to -4) to the mtns this afternoon and early evening.

If a TSTM forms over the la mtns it will likely drift into the
antelope vly.

Stratus and or stratu CU look a little thinner than it did last
night so there is a slightly better chc of some afternoon clearing
but think there will be one more gloomy day across the coasts and
vlys. Hgts today will be near 567dm or 11 dm below normal. These
low hgts... Onshore flow and clouds will all combine to make today
the coolest of the next 7 with MAX temps running 8 to 12 degrees
blo normal.

The upper low will move to the east on Tuesday. The marine layer
will be unchanged and it will likely be another gloomy day south
of pt conception (a more normal marine layer will allow for
typical late morning clearing on the central coast) that said, its
pretty unusual for the marine layer to hang tough for so many days
in a row so there is a decent chc of some afternoon clearing.

A weak ridge pops up for Wednesday. This smoosh the marine layer
some and increase the strength of the inversion. Onshore flow
weakens some and there will be a typical late morning clearing.

Max temps will be warmer but still 3 to 6 degrees blo normal.

Long term (thu-sun) 21 309 am.

The xtnd forecast is all about another cut off low. This low will
form about 900 miles to the west of pt conception on Wednesday and
will then slowly move to the NE over the course of the next 4
days.

At one time the ec took this upper low southward and over socal
while the GFS moved it north of the bay area. A couple of days ago
both mdls agreed that the low would move to or to the north of the
bay area. Now, just to keep things interesting, the GFS brings the
low more to the south while the ec keeps it to the north.

Will ignore the GFS and go with the forecast that looks most
likely. Look for a typical night through morning low cloud pattern
across the coasts and most of the vlys. Hgts do rise through the
period and there will be a slow warming trend but still with blo
normal MAX temps.

Aviation 21 1037z.

At 1025z, the marine inversion at klax was based around 4000 feet.

The top of the inversion was 4800 feet with a temperature of 12
degrees celsius.

Overall, moderate confidence in coastal valley TAF sites and high
confidence in desert tafs. With deep inversion, coastal valley
cigs are ranging between MVFR and lowVFR. Expect MVFR CIGS north
of point conception to dissipate by late morning and then return
late this evening and overnight. For sites south of point
conception, expect MVFR lowVFR CIGS to continue through this
morning withVFR CIGS this afternoon. For tonight, MVFR CIGS will
return albeit at slightly lower levels.

Klax... Moderate confidence in 12z taf. Current MVFR CIGS could
rise toVFR levels several hours earlier than current 19z
forecast. There is a 30% chance CIGS will scatter out this
afternoon. For tonight, high confidence in return of MVFR cigs,
but only moderate confidence in timing.

Kbur... Moderate confidence in 12z taf. Current MVFR CIGS could
rise toVFR levels several hours earlier than current 19z
forecast. For tonight, high confidence in return of MVFR cigs, but
only moderate confidence in timing.

Marine 21 136 am.

For the outer waters, high confidence in current forecast. Small
craft advisory (sca) level winds will continue through tonight.

For Tuesday through Thursday, winds and seas will remain below sca
levels. On Friday, there is a 60% chance of SCA level winds,
especially across pzz673 676.

For the inner waters, high confidence in current forecast. For the
waters north of point sal, SCA level winds will occur this
afternoon and evening then winds seas are expected to remain below
sca levels Tuesday through Friday. For the waters south of point
conception, winds and seas will remain below SCA levels today
through Thursday with a 50% chance of SCA level winds on Friday
across western sections.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect until 3 am pdt Tuesday for
zones 645-670-673-676. (see laxmwwlox).

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.
