Synopsis 21 226 pm.

High pressure will bring generally warm and dry conditions to the
area through the middle of next week. There will also be varying
amounts of night and morning low clouds and fog along the coast
and into some valleys during the period. Dry weather with a
gradual cooling trend can then be expected late next week.

Short term (tdy-tue) 21 223 pm.

Some hi clouds associated with a weak upper level low well SW of srn
ca moved into the forecast area this afternoon, otherwise mostly
sunny skies were noted across the region and will continue thru
sunset. Weak upper level riding over SRN ca today combined with
offshore gradient trends contributed to above normal temperatures
away from the immediate coast. Highs this afternoon in the warmest
vlys will be in the 80s to around 90, with upper 70s to low 80s for
inland coastal sections.

Weak upper level ridging should prevail over the forecast area
tonight as that weak upper level low passes several hundred miles s
of the region and into NRN baja by late tonight. The upper ridging,
with h5 heights ranging from 578 to 581 dm, will then continue
across SRN ca Sun thru Mon night. A broad upper level trough
developing over the eastern pacific will help to slightly weaken the
upper ridge over swrn ca for tue.

12z nambufr soundings at klax showed a pretty strong marine
inversion at 250 ft deep late tonight, then increasing to only 400
ft deep for late Sun night early Mon morning. NAM boundary layer
moisture fields indicate not much in the way of low clouds tonight
with light offshore flow over slo sba counties and also for
inland areas of vtu l.A. Counties, and a weak eddy just off the
coast S of point conception. Any low clouds tonight will likely be
confined mainly to the immediate coast, but should remain over
the coastal plain. Expanded low clouds are indicated mainly for
coastal areas Sun night into Mon morning with patchy dense fog not
out of the question. Patchy low clouds and dense fog may sneak into
the southern san gabriel vly by early Mon morning as well.

Additional low clouds and fog with a deeper marine inversion is
expected for the coast and some vlys Mon night into Tue morning as
well.

Otherwise, mostly clear skies will prevail across the forecast area
tonight through tue, with afternoon and early evening onshore
breezes expected. Temps will remain several degrees above normal
away from the immediate coast on sun, then cool slightly but remain
slightly above normal for most areas for mon. Temps on Tue should
drop several more degrees to near normal to slightly above normal
for many areas. Highs in the warmest vlys will reach mainly into the
80s on sun, upper 70s to mid 80s mon, and mid 70s to low 80s on tue.

Highs in the antelope vly are forecast to be well above seasonal
norms during the period, with readings in the 80s for the most
part.

Long term (wed-sat) 21 223 pm.

The ec and GFS are in generally good agreement on wed, then start to
become quite different thru the end of the week. As a result, the
extended forecast confidence starts out pretty good for Wed then
goes down as we head into next sat. The upper trof over the E pac is
forecast to deepen into an upper level low about 600 nm W and NW of
the forecast area by Wed evening. The upper low will meander over
the E pac thru thu, then the ec tracks it NE and into far NRN ca by
early sat, while the GFS wobbles it about well off the central ca
coast thru Fri night then pushes it to just off the sba county coast
by late sat, with a surface low pressure area just off the central
coast at that time. The GFS does bring showers into the forecast
area sat, but decided with so much uncertainty between the ec and
gfs, kept the wx dry thru the day with ghost pops under 15 percent.

The forecast will remain dry Wed thru sat, with night and morning
low clouds and fog expected for the coastal and vly areas at least
thru fri. Otherwise, skies should be mostly clear thru Fri then turn
partly cloudy on sat.

A gradual cooling trend is forecast thru the extended period. Temps
wed should be near normal to slightly above normal, then drop to
near to slightly below normal across the region by Fri and sat.

Highs in the warmest vlys should reach the mid 70s to lower 80s wed,
70s to around 80 Thu and fri, and 70s on sat.

Aviation 21 1720z.

At 17z, the marine layer at klax was 500 feet deep. The top of
the inversion was 3000 feet at 20 degrees celsius.

Moderate confidence inVFR conditions everywhere through 08z with
seasonal onshore flow. Moderate confidence that marine layer will
stay shallow tonight into Sunday, albeit maybe slightly deeper
than today. Moderate confidence that any restricted flight cats
will be primarily lifr... Or ifr at the best. Low confidence in
timing and areal coverage of clouds however. Cig chances for
tonight... 80% klax... 60% klgb ksmo ksmx kprb... 40% koxr kcma... 20%
ksbp.

Klax... Moderate confidence inVFR through 08z with seasonal
onshore flow. 20% chance of bkn004 forming with seabreeze 23-04z.

80% chance of ceiling tonight with arrival window of 07-11z. If
ceilings form, lifr likely. Any SE winds should stay under 08 kt.

Kbur... High confidence inVFR through Sunday with seasonal
southerly winds. 5% chance of lifr conditions 10-16z Sunday.

Marine 21 122 pm.

Moderate confidence on fog forecast. Patches of drifting dense
fog (1 mile or less visibility) will likely continue through at
least Sunday, if not Monday. It is too difficult however to
predict exactly where those patches will be and when. Widespread
short period seas will remain mixed with long period west and
south swells. The buoys may favor reporting the more energetic
long period swell into tonight, but the short period swells will
likely persist through the weekend.

Moderate confidence in low-end small craft advisory (sca) winds
and or seas off the central coast through tonight, with the worst
conditions beyond 20 miles from shore. Not expecting any SCA after
that through the middle of next week, other than localized 10 foot
seas off the central coast on Sunday.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect until 9 pm pdt Sunday for zone
670. (see laxmwwlox).

Small craft advisory in effect until 3 am pdt Sunday for zone
673. (see laxmwwlox).

Hazard potential outlook (tue-sat)
No significant hazards expected.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.
