AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
422 AM PDT Sat Oct 7 2017

.SYNOPSIS...
High pressure and offshore flow will result in another hot day
across the region away from the coast. An upper trough will move
through the Pacific Northwest and into the Great Basin on Sunday
and flow will turn onshore. This will bring much cooler weather
to the region. An offshore flow pattern will bring gusty Santa
Ana winds to portions of Southwest California Sunday night through
Tuesday morning, and it will be warmer. A cooling trend is
expected to begin Wednesday.

&&

.SHORT TERM...(TDY-MON)

Clear skies across the region this morning, and with the exception
of a few high clouds, today will be sunny. Pressure gradients
between KLAX and KDAG were between 3 and 4 mb offshore, slightly
more so than at this time on Fri. There should be some locally
gusty NE winds across L.A. and VTU Counties this morning, but
they should remain below advisory levels. Gradients are expected
to turn onshore this afternoon, whereas they remained offshore all
day on Fri. This should bring a few degrees of cooling to the
coastal plain today, especially near the beaches. However, even
there, temps will rise quickly this morning, and if the sea breezes
are delayed enough, it will get nearly as warm. Expect similar
max temps today in the valleys, or there may even be a degree or
two of warming. High temps in a couple of the hotter valley
locations could reach 100 degrees today. There should also be a
couple of degrees of warming in the mtns and deserts today.

A trough will move through the Pac NW and into the Great Basin
tonight and Sunday. Models show an eddy circulation tonight and
Sunday morning, with strong onshore gradients developing. The WRF
indicates low clouds moving northward into at least coastal
sections of L.A. County and probably Ventura County late tonight
and Sunday morning, and it is not out of the question that clouds
could push into some valley areas. Clouds could linger at the
beaches of L.A. and VTU Counties well into the afternoon on
Sunday. There will be significant cooling on Sunday, with max
temps down as much as 12 to 18 degrees in some valley areas
and across far interior portions of the coastal plain.

The upper trough in the Great Basin will move eastward Sunday
night and Mon, and a strong surface high will settle into Nevada.
Pressure gradients will rapidly reverse, and are forecast to be
nearly 8 mb offshore between KLAX and KDAG Mon morning. There
could be some low clouds across coastal sections of L.A. County
Sunday night, but those should be whisked off the coast by the
developing offshore flow. Strong offshore gradients, cold air
advection, and fairly good upper level support with strong winds
at 850 mb should result in some decent Santa Ana winds across much
of L.A. and VTU Counties Monday. At this point, it looks almost
certain that Wind Advisories will be needed across most of L.A.
and VTU Counties, and High Wind Warning level winds are certainly
possible. Max temps will likely rise several degrees west of the
mountains on Mon, but will likely fall significantly in the mtns
and deserts.

.LONG TERM...(TUE-FRI)

Broad upper ridge will become zonal flow across Southwestern CA on
Tue, and heights will rise slightly or change little. Gradients
will still be offshore, in the morning, then will flip onshore.
There should be several degrees of warming on Tue in the mtns and
deserts, little change or slight warming in the valleys, and some
cooling across the coastal plain, mainly near the beaches. A
trough will move into the West Coast on Wed, causing
heights/thicknesses to fall. Low level flow will be increasingly
onshore. This should bring a few degrees of cooling to most
areas Wed. The upper trough across the West Coast will sharpen and
dig some Thu, so expect some additional cooling. Then, expect
little change in temps on Fri as the trough remains in place.
Night through morning low clouds will probably return to coastal
areas Wed night and Thu, and become more widespread Thu night and
Fri. There is a chance that low clouds could return as early
as Tue night, but that appears unlikely at this time.

&&

.AVIATION...07/12z.

At 0830z at KLAX... the inversion was surface based. The top of
the inversion was around 1900 feet with a temperature of about 33
degrees Celsius.

Overall... High confidence in the current TAFs. Patchy fog and low
clouds are possible in the Los Angeles Basin Sunday morning.
Otherwise and elsewhere VFR conditions will prevail.

KLAX... High confidence in the current TAF. Patchy fog and low
clouds are possible Sunday morning. Otherwise VFR conditions will
prevail. There is a ten percent chance of east winds to 10 kt
through 16z today and again 08/09z-14z.

KBUR... High confidence in the current TAF. VFR conditions will
prevail through the forecast period.

&&

.MARINE...07/230 AM.

Small Craft Advisory (SCA) level winds will develop across the
northern and central outer waters tonight and continue through at
least Sunday evening. There is a 40 percent chance of Gale Force
winds north of San Miguel Island during this time and into Monday.

Winds across the inner waters are expected to remain below SCA
levels though there is a 25 percent chance of SCA winds
developing on Sunday and possibly into Monday. There will be
locally gusty winds tonight through Monday at times along the
coast from Ventura southward. The locally gusty winds may extend
as far offshore as Catalina Island on Monday.

A long period south swell will continue over the coastal waters
this weekend resulting in hazardous breaking waves near shore
through late Sunday.
