Synopsis
Night and morning low clouds and fog are expected for the coast
and some valleys trough next Friday. Otherwise, clear to party
cloudy skies can be expected through the period. High pressure
will bring warmer temperatures to the area this weekend into
Monday, then low pressure will result in cooler temperatures
Tuesday through late next week.

Short term (tdy-mon)
the marine layer is now at 3500 feet and is capped by a weak
inversion. It will transition to a shallower depth as a ridge
builds in from the west. Due to the weak inversion and strong
offshore trends this morning's stratus deck will not develop
fully. The best cloud coverage will be across the la coast and the
san gabriel vly where a weak eddy is helping things along. Unlike
the past few days there will be total clearing and a sunny
afternoon. MAX temps will be up 3 to 6 degrees from ydy but will
still be 3 to 6 degrees blo normal.

Better weather on tap for Sunday and memorial day. The marine
layer will lower to about 1500 feet and the onshore flow will
relax a few more mb. There will be a coastal stratus layer
extending locally into the coastal vlys each night and morning.

There will be total clearing each day. The ridging will allow for
some warming each day. 3 to 6 degrees Sunday and a degree or two
on Monday.

Long term (tue-fri)
the GFS and the ec agree that fairly dull june like weather is in
store for SRN ca for the rest of next week. On Tuesday the ridge
will be replaced by a weak trof that will then persist over the
west coast through Thursday. This trof along with slightly
increased onshore flow will bring three similar days will night
through morning low clouds and for the coasts and many of the
vlys. MAX temps will cool Tuesday and then again Wednesday and the
marine layer deepens a little more. Thursday will be very similar
to Wednesday. MAX temps will be a few degrees blo normal through
this period.

A little ridge will move in Friday and this will smoosh the marine
layer down out of most of the vlys and kick off a warming trend.

Aviation
27 1005z
at 1005z, the marine inversion at klax was based at 3500 feet. The
top of the inversion was 5700 feet with a temperature of 14
degrees celsius.

Overall, low to moderate confidence in 12z taf. Cloud coverage
this morning is rather chaotic as CIGS form and dissipate and cigs
range fromVFR to ifr levels. Any clouds should dissipate by early
this afternoon. For tonight, moderate confidence in return of
stratus to coastal TAF sites, but low confidence in timing and
flight category.

Klax... Low confidence in 12z taf. There is a 30% chance of MVFR
cigs 12z-20z. For tonight, high confidence in return of stratus,
but low confidence in timing (+ -4 hours of current 06z forecast)
and flight category (could range from MVFR to ifr).

Kbur... Moderate confidence in 12z taf. There is a 20% chance of
MVFR CIGS 12z-18z. For tonight, there is a 30% chance that MVFR
cigs could develop.

Marine
27 130 am
for the outer waters, moderate confidence in current forecast.

For today, small craft advisory (sca) level winds are expected
across pzz673 with a 40% chance of SCA level winds across pzz670
and pzz676. For Sunday into the middle of next week, northwest
winds will increase with SCA level winds likely across all the
outer waters, especially during the afternoon evening hours.

For the inner waters, moderate confidence in current forecast. For
the waters north of point sal, winds will hover near SCA levels
each afternoon evening through Monday (with a 30% chance of sca
winds developing). For Tuesday Wednesday, winds will be on the
increase with SCA level winds likely in the afternoon evening
hours. For the waters south of point conception, winds and seas
are expected to remain below SCA levels through Monday. For Monday
and Tuesday, winds will increase a decent chance of SCA level
winds in the afternoon evening hours across western sections.

Lox watches warnings advisories

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.
