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 23 918 am.

Temperatures will cool off slightly, with extensive low clouds
and fog expected for the coast and valleys over the weekend. High
pressure will strengthen, bringing warmer temperatures and a
decrease in cloudiness for early next week.

Short term (tdy-tue) 23 142 pm.

The marine inversion early this afternoon was near 2800 ft deep or
so at lax. A large and strong eddy circulation kept a broad SE flow
over the socal bight into the coast this afternoon, along with
stubborn low clouds along the coastal plain S of point conception.

A southerly flow also helped to keep low clouds along the
immediate central coast this afternoon. In addition, 12z nam
forecast gradients at 00z this afternoon include +10.1 mb lax-dag
and +6.8 mb lax-bfl. These strong onshore gradients will help to
keep low clouds near or over the coastal plain thru the rest of
the afternoon. Otherwise, mostly sunny skies will prevail across
the region thru sunset. Highs are going to be quite warm over the
region again today, with the hottest interior vlys and lower mtns
expected to reach the 90s to around 102. For the vlys adjacent to
the coast, highs should be mostly in the 80s to around 90.

An upper level high off the SRN ca coast will persist in that
area thru sun, with very weak upper level troffiness expected over
srn ca tonight into Sun morning. Upper ridging will build back
into SRN ca Sun afternoon thru tue. H5 heights thru the period are
generally expected to be rather high and in the 589-592 dm range.

The marine layer will deepen some tonight into Sun morning to around
1500 ft N to 2500 ft or slightly hier s. Extensive marine layer
clouds and some fog can be expected for the coast and vlys tonight
into Sun morning. In addition, the persistent SE to S flow at low
levels should help to contribute some upslope flow into the
foothills, with patchy drizzle not out of the question for the
coast, vlys and lower coastal slopes S of point conception. Will add
mention of patchy drizzle for these areas tonight into Sun morning
with the afternoon forecast package. The low clouds should clear to
the coast Sun afternoon, but may be persistent in a few areas such
as the oxnard plain. There should be a slightly lower marine
inversion Sun night and Mon night. Low clouds and fog are expected
to return quickly to the coast and vlys during the evening hours,
then clear to or off the coast my midday to early afternoon each
day. Otherwise, mostly clear skies will prevail over the forecast
area thru tue.

No major issues are anticipated with regards to winds through tue.

Moderate to strong onshore gradients will generate the usual gusty
afternoon evening southwesterly winds across the mountains and
deserts, but should be generally below advisory levels.

Temperatures are forecast to cool some sun, but remain several
degrees above normal for interior areas, then warm back up a few
degrees for most areas on Mon and tue. Highs in the warmest interior
vlys and lower mtns Sun should reach the mid 80s to lower 90s,
except mid 90s to around 100 in the antelope vly, then warm into the
upper 80s to lower 90s Mon and 90s tue, except upper 90s to 103 in
the antelope vly. For the vlys adjacent to the coast, highs will be
in the upper 70s to mid 80s Sun and mid 80s to around 90 Mon and
tue.

Long term (wed-sat) 23 144 pm.

The 12z GFS and ec are in generally good agreement with the large
scale features Wed thru fri, then differences show up for sat. Upper
level troffiness is forecast along the ca coast Wed thru fri, with
h5 heights possibly lowering to 585-587 dm by Fri morning per the
gfs and not quite as low for the ec. The GFS hangs onto the upper
trof with even lower h5 heights into Sat while the ec builds heights
with upper ridging nosing back into the area from the E pac. Will
lean slightly more toward the climatologically favored GFS (upper
troffiness into SRN ca) for the extended forecast.

It looks like the marine layer pattern will prevail Wed thru sat
with night and morning low clouds and fog for the coast and vlys,
altho the marine inversion will fluctuate some during the period,
probably shallowest Wed then increasing some thru sat. Otherwise,
mostly clear skies will prevail thru the period. Decent onshore
gradients should bring typical breezy to locally gusty S to w
afternoon and evening winds each day to the region, especially over
the mtns and deserts. Temps should be near normal to several degrees
above normal on wed, then cool a few degrees to near normal to
slightly below normal overall by Fri and sat.

Aviation 23 2036z.

At 20z at klax... The inversion was around 2600 feet deep. The
top of the inversion was around 4400 feet with a temperature of
about 26 degrees celsius.

Overall north of point conception... Moderate confidence in the
current tafs. Lifr ifr conditions will develop along the coast and
into adjacent valleys 05z-10z then will linger through the
remaining forecast period.VFR conditions will prevail otherwise
and elsewhere including at kprb.

Overall south of point conception... Low to moderate confidence
in the current tafs along the coast and in adjacent valleys with
high confidence in the current kpmd and kwjf tafs. Ifr MVFR
conditions will be slow to clear today and CIGS may simply rise
intoVFR criteria for a few hours rather than scatter or clear.

Lifr ifr conditions will return to the coastal and adjacent valley
areas 01z-05z and will continue through the forecast period for
most terminals and through 20z-22z at klax. Otherwise and
elsewhereVFR conditions will prevail.

Klax... Moderate confidence in the current taf. MVFR CIGS have a
thirty percent chance of scattering clearing today and a ten
percent chance of rising intoVFR criteria for a few hours. MVFR
conditions will return 01z-05z and will continue through 20z-22z
with a thirty percent chance of ifr conditions during the period.

OtherwiseVFR conditions will prevail. There is a eighty percent
chance of southeast winds greater than eight knots continuing
through the day. There is a sixty percent chance of gusts up to 20
kts continuing through 22z and a twenty five percent chance
through 24 01z.

Kbur... Moderate confidence in the current taf. MVFR conditions will
be slow to clear today and CIGS may simply rise intoVFR criteria
for a few hours rather than scatter or clear. MVFR conditions will
return 01z-05z and will continue through the end of the forecast
period with a thirty percent chance of ifr conditions during the
period. OtherwiseVFR conditions will prevail.

Marine 23 143 pm.

For the outer waters... Small craft advisory (sca) level winds
will continue through mid afternoon for the central outer waters.

After a period of diminished winds... The winds in this zone will
increase again overnight and into tomorrow and a new advisory
will be issued for the later period. The strongest winds are
around and south of point conception including the western portion
of the santa barbara channel. Conditions in the northern and
southern outer waters will remain below SCA levels through
Wednesday though the winds and seas will be elevated at times.

For the inner waters north of point sal... Conditions will remain
below SCA levels through Wednesday.

For the inner waters south of point conception... Conditions will
remain below SCA levels through Wednesday. However... Southeast
winds will strengthen overnight and into tomorrow with gusts
reaching SCA level at times. The winds will be strongest across
the western portion of the santa barbara channel.

Fire weather 23 1142 am.

Strengthening onshore flow combined with a deepening marine layer
pattern will bring a gradual cooling trend for most areas, especially
coastal and valley areas. Temperatures will still remain very warm
today across interior sections, with some triple digit readings today
across the antelope valley and interior valleys of san luis obispo
county, with some cooling on Sunday. Humidities in these areas as
well as the mountains will fall into the 8 to 15 percent range today,
then trending higher on Sunday. Strengthening onshore winds will
add to the fire weather threat across interior sections today and
Sunday, with gusts generally ranging between 25 and 40 mph across
the mountains, deserts, and interior valleys, with isolated gusts
as high as 50 mph in the foothills of the antelope valley. As of
10 am, the lax-daggett gradient is around +6 mb, and is expected
to peak around + 9 mb later this afternoon. The combination of very
warm and dry conditions combined with these strong onshore winds
will bring elevated fire danger through the weekend across the
mountains, deserts, and interior valleys of san luis obispo county,
with the potential for brief critical fire weather conditions
today. The greatest fire weather threat today and tomorrow will be
the highway 14 corridor from santa clarita valley to the antelope
valley.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect until 3 pm pdt this afternoon
for zone 673. (see laxmwwlox).

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