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.

807 pm pdt Sun jun 17 2018

Synopsis 17 757 pm.

Winds will be strong and gusty in the los angeles county foothills
and high desert areas into the overnight hours. Low clouds will
return to the coastal and adjacent valley areas tonight and will
linger well into Monday before some afternoon clearing occurs.

Temperatures will be cool on Monday then will warm significantly
through the week.

Short term (sun-wed) 17 805 pm.

As for today, some areas, mainly across the santa barbara south
coast and adjacent foothills and the coast and valleys of ventura
county recorded light measurable rain overnight into this morning.

Surprisingly, nothing across the san gabriel foothills and NW slo
county. All this due to the upper trough moving over the area and
some positive vorticity advection (pva) to cause some lift to
squeeze out some moisture. Nothing more than a tenth of an inch,
but for this time of year, very unusual. Here is some top of the
news headlines for socal... Camarillo airport broke today's all
time rainfall record for this day with all of 0.01" rain
surpassing the trace of rain it received in 1968.

High temps were 2 to 7 degrees cooler across much of l.A. And
ventura counties as well as interior sba county, with double
digit cooling in the antelope valley compared to yesterday.

However, the sba coast and valleys and all of slo county were 2
to 5 degrees warmer today. Mainly due to the skies clearing up
across the northern half of the forecast area. Still, it was quite
cool around the entire forecast area where most areas were in the
60s with only a few sites reached the lower 70s.

Latest goes-16 vis satellite imagery this evening indicated clear
skies across san luis obispo and santa barbara counties, except
near the ventura county border with some clouds across the south
coast and adjacent foothills. Otherwise, much of ventura and l.A.

County remain under partly to mostly cloudy skies. Plenty of low
clouds off all coastal waters that will start to push inland as
well this evening under the deeper stratocu deck over socal. The
catalina eddy will continue to draw in the low clouds and should
low clouds reach the coastal slopes once again, but not quite as
deep as last night or this morning. Not expecting any light rain
as the trough axis is moving east. Some patchy drizzle can't be
ruled out in some foothill communities, but not in the current
forecast.

The wind advisory for the antelope valley will be extended
through 3am, but mainly for the lake palmdale area. Most areas
have lowered to below advisory levels, but winds around lake
palmdale will continue to be locally strong with sustained winds
between 30 and 40 mph with gusts around 50 to 60 mph. This is an
isolated area, therefore will continue the wind advisory through 3
am Monday morning. The moist layer depth was around 4500 ft this
evening, and decent confidence that clouds will continue to remain
over la vtu and sba counties, and eventually fill in across the
northern coast and valley locations. By Monday morning, the marine
layer should start to decrease some as the upper trough will
begin to pull out towards the NE while an upper level ridge begins
to nudge in from the SW towards socal. There is still a good
chance that low clouds or stratocu cloud deck will remain over the
coast and valleys through mid day, but should see better clearing
or partly cloudy skies later in the day. High temps will trend
higher on Monday with valleys and interior areas rising a good 6
to 13 degrees,while coastal areas get 2 to 4 degrees warmer. Slo
valleys and antelope valley will reach the mid 80s, while other
valleys and inland coastal areas will reach the lower to mid 70s.

***from previous discussion***
the upper low will push into idaho on Monday and heights will
rise by about 5 dm to 586 dm in the middle of the cwa. There will
also be a north gradient and a slightly offshore east gradient
resulting in better clearing. More sunshine and higher heights
will combine to bring warmer temps throughout the CWA with the
biggest jump inland. The coastal areas will only warm a small
amount as there will still be a stronger than normal sea breeze.

Even with the increase, afternoon temperatures will remain below
average.

Ridging sets up on Tuesday as the upper high to the SW begins to
assert itself. Heights will increase to about 590 dm. The marine
layer will shrink out of the valleys but will be trapped under a
strengthening inversion and remain at the coasts. Afternoon high
temperatures will increase to reach or slightly exceed normals.

Long term (thu-sun) 17 150 pm.

Models continue to show a heat wave setting up on Thursday as a
large upper high moves atop of socal. Heights will rise to 594
dm. Down at the surface, the onshore gradient winds and coastal
eddy will continue. There will be a shallow marine layer across
the coasts each night through morning. The capping inversion will
be very strong and it might make it tough for the low clouds to
clear at the beaches. There will be huge difference in afternoon
maximum temperatures: beach temps will be near normal... Valley
temps will be 5 to 10 degrees above normal, and inland temps will
8 to 12 degrees above normal. The overnight minimum temperatures
will also rise to above normal and there will likely be a small
zone at the top of the inversion where minimum temperatures could
be substantially above normal. Its not impossible that there could
be some heat advisories on Thursday.

The models diverge a bit on Friday on specifics, but the general
warm trend should continue with little change to the sensible
weather. Saturday and Sunday should each bring the ridge down a
bit but temperatures will remain above normal.

Aviation 18 0222z.

At 0109z at klax... The marine layer was 4500 feet deep. The top
of the inversion was at 6800 feet with a temperature of 12 c.

Low confidence in the 00z TAF package with timing of low clouds
returning and scouring out Monday. Moderate confidence that cigs
will remain in MVFR toVFR categories tonight.

High confidence in desert tafs through the period.

Klax... Low to moderate confidence in 00z taf. CIGS will likely
stay between MVFR and lowVFR through tomorrow morning. Low
confidence for timng of clouds to scour out. There is a 30 percent
chance of bkn conditions all day.

Kbur... Low to moderate confidence in 00z taf. CIGS will likely
stay between MVFR and lowVFR through 16z. 40% CIGS will continue
through 20z.

Marine 17 1057 am.

High confidence in current marine forecast. Winds and seas are
expected to remain below SCA levels across the coastal waters
through at least Monday morning. There is a 30 percent chance of
sca winds for the outer waters NW of san nicolas island Monday
evening and night and a 70 percent chance Tuesday evening and
night. At least local SCA wind gusts will likely extend into the
inner waters north of point conception and the western portion of
the E santa barbara channel at that time. SCA winds across these
areas will likely continue for much of the remainder of next week.

A moderate to possibly strong eddy may persist for much of the
forecast period with sustained SE winds around 10 kt with gusts
locally up to 20 kt possible each night to early morning for the
inner waters south of point conception including the san pedro
channel.

Lox watches warnings advisories
Ca... Wind advisory in effect until 9 pm pdt this evening for zone
59. (see laxnpwlox).

Pz... None.

Hazard potential outlook (wed-sun)
No significant hazards expected.
