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 25 910 am.

A trough of low pressure will persist over the region through
Saturday before departing to the east while weakening into early
next week. This will support continued cool and unsettled weather
into Saturday before warming into early next week. Temperatures
are expected to cool down a bit as another low pressure is
expected to move across by midweek.

Short term (tdy-sun) 25 936 am.

Marine layer depth this morning has topped the 850mb level, so
probably in the 5000-6000' range. An upper low has moved very
close to the bay area this morning with very moist conditions in
the lower levels. However the coastal inversion has weakened quite
a bit with the upper low and colder air aloft so cloud cover is a
bit more chaotic than usual. Temps will remain several degrees
below normal. A few scattered light showers have developed mainly
north of pt conception this morning and expect those to continue
into the afternoon with amounts mostly under a tenth of an inch.

Forecast looks on track as 12z models aren't offering much in the
way of changes from earlier model runs so cool weather with plenty
of clouds through Saturday then warming through early next week.

***from previous discussion***
an upper low about 100 miles west of monterey will move into the
bay area this afternoon. There is a slight chance of showers in
areas north of pt conception, closest to the upper low today.

Skies should stay mostly cloudy from the coastal slopes westward
today, although there is a slightly better chance of some
sunshine this afternoon, especially near the coast. MAX temps
today should be similar to those on thu, remaining far below
normal, especially in the valleys. The exception will be across
the mountains and antelope valley, where there should be 6 to 12
degrees of cooling. Gusty southwest to west winds will affect the
mountains and antelope valley this afternoon and evening, but they
should remain just below advisory levels, with local advisory
level gusts near lake palmdale.

A strong vort wrapping around the western periphery of the upper
low will cause it to elongate in a positively tilted manner later
today, then the southern end of this system will sweep across the
region tonight. This should maintain plenty of clouds in all areas
with the exception of the eastern sections of the antelope valley
tonight and Saturday morning. There will likely be patchy
drizzle, especially across portions of l.A. And vtu counties, with
some light measurable rain possible across the foothills and
valleys, and on northern slopes. North-south gradients will become
offshore across sba county tonight, which could produce locally
gusty winds through and below passes and canyons of the santa ynez
range and keep skies mostly clear. However, the 06z run of the wrf
has really backed off on this, so expect less in the way of
winds, with winds remaining below advisory levels.

The trough axis will move well to the east of the region by
Saturday afternoon, so expect skies to become partly cloudy in
most areas. MAX temps should be up a few degrees in most areas,
but will still be well below normal. The except could be across
the south coast of sba county, where increasing north to south
gradients should cause some gusty northwest winds to develop in
the afternoon, bringing more in the way of warming. Gusty west
winds will affect the l.A. County mountains and the antelope
valley in the afternoon.

North to south gradients will cause gusty northwest to north
winds through and below passes and canyons of the santa ynez range
Saturday night, possibly to advisory levels, with gusty but
sub-advisory level winds through the i-5 corridor.

The upper low will move slowly eastward into nevada Sat night,
then move very slowly eastward on Sunday. Expect a more
traditional marine layer to develop, with night through morning
low clouds and fog in coastal and valley areas, with the exception
of the south coast of sba county, where northerly winds should
keep skies clear. It should become mostly sunny across the region
Sunday afternoon. MAX temps should be up 3 to 6 degrees in most
areas Sunday, except 6 to 12 degrees in the mountains, interior
valleys and antelope valley, rising to near normal levels.

Long term (mon-thu) 25 424 am.

The upper low will move slowly into utah Sunday night and Monday,
and heights across the region will continue to rise. The marine
layer should become more shallow, with night through morning low
clouds less widespread across the interior valleys, but still
widespread in most coastal and lower valley areas. MAX temps
should rise several degrees in most areas, likely to near or
slightly above normal in coastal and valley areas, and several
degrees above normal in the mtns, deserts and interior valleys.

Expect little change on tue, then there should be significant
cooling on Wed as a trough approaches the west coast and onshore
flow increases. The trough axis will move into ca on thu, so there
will likely be some additional cooling.

Aviation 25 1807z.

At 1703z the marine inversion at klax was around 5000 ft deep. The
top of the inversion was around 6000 feet with a temperature of 5
deg c.

Moderate confidence overall in the 18z tafs. Stratocu with generally
vfr CIGS will prevail this afternoon into the early evening for most
of the coastal and vly airfields, with occasional MVFR CIGS possible
at kprb and ksbp thru early this afternoon. Low clouds with mostly
MVFR conditions can be expected to redevelop at most of these
airfields this evening then persist into mid to late Sat morning.

There is uncertainty in the timing of the MVFR CIGS tonight which
could be off + - two or more hours.

For ksba, kwjf and kpmd, there is hi confidence inVFR tafs thru sat
morning. Gusty SW winds will affect the desert airfields this
afternoon and evening, and Sat morning.

Klax... Moderate confidence overall in the 18z taf. Stratocu with
generallyVFR CIGS will prevail this afternoon into the early
evening then low clouds with MVFR conditions can be expected from
about 03z this evening to around 18z Sat morning, withVFR cigs
expected thru Sat afternoon. There is uncertainty in the timing of
the MVFR CIGS tonight and improvement toVFR later Sat morning which
could be off + - two or more hours.

Kbur... Moderate confidence overall in the 18z taf. Stratocu with
generallyVFR CIGS will prevail this afternoon into the early
evening then low clouds with MVFR conditions can be expected from
about 06z this evening to around 15z Sat morning, with improvement
toVFR CIGS for mid to late Sat morning. There is uncertainty in the
timing of the MVFR CIGS tonight and improvement toVFR Sat morning
which could be off + - two or more hours.

Marine 25 857 am.

For the outer waters, moderate to high confidence in the current
forecast. Winds and seas will remain below small craft advisory
levels through mid-afternoon. There is a 70%-80% chance of small
craft advisory level northwest winds across the southern portion
of the outer waters from point conception to san nicolas island
from late this afternoon or early evening through early Monday
morning. There is also a 60% chance of advisory level gusts for
the northern portion of the outer waters from Saturday afternoon
through Sunday night.

For the inner waters, moderate to high confidence in the current
forecast. For the waters north of point sal, winds and seas will
remain below small craft advisory level through Monday, except for
a 40% chance of advisory level winds Saturday afternoon and
evening.

For the waters south of point conception, winds and seas will
remain below SCA levels through mid afternoon. From late this
