Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
156 PM PST Mon Nov 16 2020

.SYNOPSIS...16/927 AM.

Moderate offshore flow in place will bring very warm and dry
conditions across the coastal and valley areas today, along with
gusty offshore winds through and below passes and canyons. Gusty
southerly winds are expected later tonight and Tuesday,
especially in the mountains as a cold front approaches. The front
will spread light rain across the Central Coast Tuesday into
Wednesday and as far south as Santa Barbara. A cooling trend will
begin Tuesday and continue through the week.

&&

.SHORT TERM (TDY-THU)...16/143 PM.

A hot day around the area, especially at lower elevations where a
number of records have been tied or broken. Breezy offshore winds
continue though they are starting to shift towards the south as a
cold front approaches from the west. This trend will continue
through tonight with south winds strengthening above advisory
levels in the mountains and interior SLO County through at least
mid day Tuesday. Higher elevations could see gusts close to 60
mph, including through parts of the I5 corridor heading into Kern
County. Hi res models indicate advisory level winds may continue
into Wednesday morning across the higher elevations of the eastern
San Gabriels.

The shift to south winds will mean an abrupt end to the hot temps
we are seeing today and highs tomorrow will be as much as 20
degrees cooler. There may even be some marine layer clouds along
the Central Coast in the morning. The cold front will spread light
rain into nrn SLO County by Tuesday evening and through SB County
Tuesday night into early Wednesday. Measurable rain is not
expected in most of LA/Ventura Counties but there could be a
sprinkle or two as the front goes through there Wednesday
afternoon. Amounts up north expected to be around a quarter inch
or less, except for up to a half inch in the coastal hills near
the Monterey County line.

Cooler weather will continue into Thursday with highs mostly in
the 60s to lower 70s. Northerly flow will be increasing through
the day and some gusty Sundowner winds are likely in srn SB County
Thursday evening, possibly near advisory levels.

.LONG TERM (FRI-MON)...16/152 PM.

North to northeast flow expected to dominate the weather pattern
through the weekend as a couple of dry troughs pass through the
area. Pressure gradient forecasts suggest winds may reach advisory
levels at times. With the troughs going through the air mass will
remain on the cool side so lower elevations temps expected to
remain in the 60s to lower 70s, warmest on Monday. Additional
warming expected Tuesday and Wednesday of next week as ridging
develops.

&&

.AVIATION...16/1743Z.

At 1740Z at KLAX, there was a surface based inversion. The top
of the inversion was around 1600 feet with a temp of 25 degrees
C.

VFR conds are expected for the region through the forecast
period. Gusty NE winds will affect the valleys and foothills of
the LA and VTU Counties until 21Z, then become diurnal SW-W winds.
Also gusty NE winds through the below passes and canyons of the
Santa Lucia Mtns in SLO County through early this afternoon. There
will be areas of LLWS and moderate UDDF. Gusty SE winds are
expected to develop tonight across much of SLO and SBA Barbara
Counties, especially in higher terrain, extending into the mtns of
VTU County.

KLAX...High confidence in the 18Z TAF with VFR conditions
through the period. E winds remaining below 7 kt Tue morning.
KBUR...High confidence in the 18Z TAF with VFR conditions through
the period.

.MARINE...16/142 PM.

Across the outer waters, moderate confidence in the forecast.
Small Craft Advisory (SCA) level SE-S winds will develop mainly
after midnight and persist through Tue afternoon across the
northern zones (PZZ670/PZZ673). SCA conds are not expected Tue
night through Wed night. There is a 60% chance of SCA level NW
winds by Thu that continue through Fri.

Across the nearshore waters of the Central Coast, moderate
confidence in the forecast. SCA level SE-S winds will develop
mainly after midnight and persist through Tue morning. There is a
50% chance of SCA level NW winds just offshore on Thu, then SCA
conds are likely Fri.

Across the inner waters south of Pt Conception, moderate
confidence in the forecast. There is a very minimal chance of SCA
