Synopsis 23 344 am.
An upper trough will pass to the north of the region today, likely
bringing some cooling in most areas, with temperatures mostly
near normal. A bit more cooling is possible Monday, then warmer
weather is expected by mid week, with temperatures above normal
Wednesday and Thursday. Cooler weather is expected Friday and
Saturday as low pressure moves into the west coast.
Short term (tdy-tue) 23 400 am.
Low clouds were widespread on the central coast and in the santa
ynez valley this morning, and were beginning to become more
widespread in coastal sections of vtu county. So far, coastal
sections of l.A. County remained clear, but expect clouds to push
into that area by morning. Skies will probably remain clear in the
valleys of l.A. And vtu counties, though some low clouds could
push into lower valley areas briefly this morning. Clouds may also
spill into the salinas valley for a few hours early this morning.
Profiler data near klax indicated that the marine layer as
deepened to about 1400 this morning, and there was 2-4 degrees of
cooling between 1000 and 1800 feet. Onshore gradients have also
increased. The WRF was showing a few degrees of cooling at 950 mb
this afternoon compared to Sat afternoon. This should lead to
several degrees of cooling today, particularly in the valleys,
with less cooling near the coast where the marine influence kept
things rather cool on sat. There may actually be some warming on
the central coast since skies are expected to clear better this
An upper trough will drop southeastward though the pacific nw
and into the great basin today and tonight. The marine layer will
likely deepen in response to this, with widespread low clouds
across the coastal plain likely pushing into many valley
locations. The WRF shows additional cooling at 950 and at 850 mb
on mon, so expect a few degrees of cooling in most areas, with
temps near to slightly below normal in most areas.
The upper trough will move into the center of the country mon
night and tue, but a weak baggy trough will hang back across
southern and eastern portions of the region. Expect mostly minor
changes to the marine layer depth and the night through morning
low cloud pattern Mon night Tue morning, with clouds widespread in
coastal areas and in many valley locations. Height rises and
weakening onshore flow may lead to a bit of warming on tue, with
the best warming in the mtns and deserts, and across slo and
northern sba counties where height rises will be greatest.
Long term (wed-sat) 23 415 am.
An upper high will be located well off the pac NW coast Tue night
and wed, as a large upper low tracks to its south, over 700 nm
west of point conception on wed. An upper ridge will develop along
and just off the west coast ahead of this upper low. Heights and
thicknesses will rise across the region, and the marine layer will
become more shallow, with night through morning low clouds likely
confined mostly to the coastal plain. Onshore gradients will
decrease a bit more and temps at 850 and 950 mb will rise. Expect
several degrees of warming in most areas on wed, with temps rising
to above normal levels. The upper low will slowly move toward ca
on thu, but heights and thicknesses will remain quite high. In
addition onshore gradients are forecast to become even weaker.
Expect little change in MAX temps across the region on thu, and
there could even be a bit more warming especially across l.A. And
The ec and the GFS are now in very good agreement showing the
upper low tracking steadily toward the coast Thu night and fri.|
Heights and thicknesses will lower, and onshore gradients will
increase. The marine layer should deepen a bit, with night thru
morning low clouds possibly reaching the valleys Fri morning.
Expect some cooling on fri, especially across slo and
sba counties, closest to the upper low. The upper low is now
forecast to move into the west coast late Fri night or sat. The
gfs maintains it as an upper low as it pushes into the bay area on
sat, while the ec shows it opening up and tracking farther north.
Either way, expect more significant and widespread cooling across
the region on sat, with any precip from this system likely
remaining north of the forecast area.
Aviation 23 1017z.
At 0930z, the marine inversion at klax was based around 1200 feet.
The top of the inversion was 2500 feet with a temperature of
24 degrees celsius.
Overall, moderate confidence in 12z taf. Lifr conditions firmly
entrenched along the central coast while stratus fog struggling to
organize south of point conception. Through sunrise, will
anticipate ifr conditions to develop across the coastal plain
south of point conception. Cig vsby restrictions should dissipate
by late morning. For tonight, will expect a near repeat of stratus
coverage, although confidence in timing is low.
Klax... Moderate confidence in 12z taf. There is a 30% chance that
vfr conditions will remain this morning. For tonight, high
confidence in return of stratus, but low confidence in timing
(could be + - 3 hours of current 07z forecast) and flight category
(could be ifr or MVFR).
Kbur... Moderate confidence in 12z taf. There is a 30% chance of
ifr conditions 13z-17z.
Marine 23 317 am.
For the outer waters, high confidence in current forecast. Small
craft advisory (sca) level winds will develop across pzz670 and
pzz673 today and continue through tonight, before diminishing.
Otherwise, conditions are expected to remain below SCA levels
For the inner waters, high confidence in current forecast as
conditions are anticipated to remain below SCA levels through
Pockets of dense fog with visibility one mile or less will remain
through this morning, especially north of point conception and
through the santa barbara channel.
Lox watches warnings advisories
Pz... Small craft advisory in effect from 3 pm this afternoon to 3
am pdt Monday for zone 670. (see laxmwwlox).
Small craft advisory in effect until 3 am pdt Monday for zone
673. (see laxmwwlox).
Hazard potential outlook (tue-sat)
No significant hazards expected.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
