Synopsis 17 736 pm.

Conditions will be cooler Monday but still warm, dry, and breezy.

Cool and cloudy weather develops on Tuesday leading to a chance of
rain and mountain snow on Wednesday and Thursday. Next weekend
will be dry with near normal temperatures.

Short term (sun-wed) 17 922 pm.

Several daily heat records fell across the region today as
offshore flow beneath high pressure aloft produced a hot day for
november standards. Weak to moderate offshore flow remains in
place across the region this evening. Onshore trends are starting
to show up along the central coast this evening as offshore flow
weakens from north to south. In the latest update, temperatures
will be nudged warmer south of point conception due to how warm
the air mass got today and cooler north of point conception due to
the weakening offshore flow.

A remnant trough of low pressure spinning off the baja california
coast will push some high clouds north into the southern portion
of the area on Monday. There is a chance that skies could be more
partly cloudy tomorrow, but due to their height, mostly clear
skies will be mentioned for now.

With the dry air mass remaining in place, overnight low
temperatures will be cold in wind-sheltered locations as clear
skies and low dewpoints will permit radiative cooling processes
to be more efficient. Mentions of patchy frost will be added for
the antelope valley and temperatures will tweaked cooler across
the wind-sheltered locations.

An update will be issued shortly.

***from previous discussion***
by Monday night the upper level trough will begin moving in from
the northwest. Lower heights, increasing cyclonic flow and the
onshore flow at the surface will all combine to bring a return of
marine layer stratus to many of the coasts and portions of the
lower valleys on Tuesday morning.

By Tuesday the offshore flow will have reversed to onshore and
increased. Skies will turn mostly cloudy in the afternoon as mid-
and high-level clouds move in from the north along with the
trough. The clouds and onshore flow will drop temperatures 10-15
degrees, bringing them back down to normal values.

Ec and GFS ensembles agree that the trough produce an upper low
that will cut off settle over socal. GEFS still moves the upper
low more to the east while the the ec is more to the west and over
the water. The ec solution starts earlier on Wednesday and
produces more rain from its over water position. Still favoring
this solution.

As most of the rain dynamics are on the southern half of the
upper low, ventura and los angeles counties will see the
more rain than santa barbara and san luis obispo counties. There
is a chance of light rain late Tuesday night and early Wednesday
morning in the south, then showers will spread over the whole
area later on Wednesday through Wednesday night. Shower activity
will diminish Thursday and end Thursday evening as the upper low
pulls out and moves to the east.

There is a non-zero convective threat on Wednesday that will be
closely monitored. The further west placement of the upper low
would place it in a good position to bring in cold air aloft for
destabilization, upper level diffluence to enhance updrafts and
good PVA to the area. All of this could add up to heavier
convective showers or thunderstorms. Still have not added thunder
into the forecast due to the continuing positional uncertainty. Any
strongly convective showers could produce rainfall intensities
that may produce problems over and near to the new burn scar
areas, especially the tick and saddleridge.

Early rainfall amount estimates call for about a tenth in san luis
obispo county, a tenth to a quarter of an inch for sba county, a
quarter to a half inch for vta county and generally a half inch to
an inch for la county. The eastern san gabriels will see the most
rain with up to 1.5 inches expected. If the system takes the
easterly track then expect half of the rain amounts and a later
start.

Snow will also be a concern as snow levels will drop to about
6,000 feet and there could be several inches or more of snowfall
in the mountains. A winter storm advisory for the los angeles and
ventura county mountains is possible.

Long term (thu-sun) 17 217 pm.

The upper-level low will move off to the east on Thursday night
and higher pressure will return to the area on Friday, lasting
through the weekend. Skies will clear to only partly cloudy and
heights will rise, increasing the temperatures over the weekend
back to seasonal levels. Offshore winds will make yet another
return over the weekend but look to be below advisory strength.

Aviation 18 0050z.

At 22z, there was no marine layer at klax. There was a surface
based inversion with a top near 650 feet and a temperature around
30 degrees celsius.

High confidence in the current forecast.VFR conditions are
expected through the period at terminals. There is a chance of
moderate wind shear between 04z and 14z at ventura county coastal
terminals.

Klax...VFR conditions are expected through the period. Any east
winds that could develop between 08z and 18z should remain less
than 5 knots.

Kbur...VFR conditions are expected through the period. There is a
10 percent chance of moderate winds shear between 10z and 14z.

Marine 17 759 pm.

For the outer waters, moderate to high confidence in current
forecast through Monday, with winds and seas below small craft
advisory (sca) levels. Monday night into Tuesday good confidence
in winds increasing to SCA levels, and continuing through
Wednesday. 20% chance of gale force gusts, especially across the
waters NW of point conception. On Thursday, moderate confidence
in conditions dropping below SCA levels as winds and seas subside.

For the inner waters north of point sal, high confidence in
winds and seas below SCA levels through Monday. For Tuesday and
Tuesday night, moderate to high confidence in winds and seas
increasing to SCA levels, then dropping below SCA levels Thursday
and Friday.

For the inner waters south of point conception, moderate
confidence in current forecast. Overall, expect conditions to
remain below SCA levels, except for a chance of gusts to 25 knots
over the western santa barbara channel Tuesday night.

Beaches 17 856 pm.

A cold storm system will move over the region between late
Tuesday and Thursday. There is a 30-50 percent chance that high
surf could develop as the storm system moves over the region
during this time. The highest chance of high surf is for the
beaches along the central coast.

Fire weather 17 311 pm.

A red flag warning remains in effect for ventura county and for
the mountains, and santa clarita and san fernando valleys of l.A.

County through 6 pm this evening.

Santa ana winds will continue to gradually diminish in strength
and areal coverage through the remainder of the afternoon hours,
with red flag warnings likely to expire at 6 pm this evening.

From tonight through Monday morning, northeast winds are generally
expected to gust between 15 and 30 mph. The offshore breezes
will continue to reinforce the very warm and dry air mass across
the region on Monday. There will be poor overnight humidity recoveries
tonight across the mountains and foothills, followed by widespread
humidity readings between 7 and 15 percent on Monday. As a result,
elevated to brief critical fire weather conditions will continue
tonight through Monday.

Lox watches warnings advisories
Ca... None.

Pz... None.

Hazard potential outlook (wed-sun)
A cooler and showery weather pattern is expected Wednesday
through Friday. Brief heavy downpours are possible, especially
Wednesday to Thursday morning. High surf is likely at all beaches
late Tuesday through early Thursday.
