Synopsis
A weak ridge aloft and shrinking marine layer will support a
warming trend through early next week. The ridge will be replaced
by a weak trough aloft by the middle of next week providing a
cooling trend with more widespread night to morning low clouds.

Short term (tdy-mon)
satellite imagery showing low clouds prevalent across much of
los angeles county coastal valley areas this morning, as well as
the the valleys of slo county. Acars sounding showing marine layer
depth currently around 3700 feet across the la basin, which is
down from yesterday's 5000 foot marine layer. With heights
building over the area today and pressure gradients trending
offshore, looking for better clearing across the district this
afternoon. As a result, temperatures expected to be up 3 to 6
degrees in most areas due to the increased sunshine except
the antelope valley which will likely see at least 10 degrees of
warming today. Onshore winds also expected to be weaker this
afternoon as compared to yesterday.

*** from previous discussion ***
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 27 900 am.

80 percent chance of low-end small craft advisory (sca)
conditions from the central coast to san nicolas island (outer
waters) late this afternoon... Becoming certain by Sunday... After
which SCA conditions should persist at least through Wednesday.

Some of the winds will spill into the western half of the santa
barbara channel each evening, but at this point does not look
expansive enough to warrant a SCA for the whole channel. These
winds will create a short period chop over all waters including
the santa barbara channel and santa monica basin (inner waters).

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect from 3 pm this afternoon to 6
am pdt Sunday for zones 670-673-676. (see laxmwwlox).

Hazard potential outlook (mon-fri)
no significant hazards expected.

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.
