Synopsis
Strong high pressure aloft and gusty santa ana winds will create
well above normal temperatures and record breaking heat through
Wednesday. Temperatures will begin cooling, but still above normal
at the end of the week.

Short term (tdy-thu)
afternoon high temperatures in many areas coming in above 100
degrees in la and ventura co. Downtown la, lax, burbank, and
camarillo all breaking records. The high pressure aloft will
continue to dominate the weather through Wednesday. 500mb heights
will be around 594 dm today and Tuesday and will fall to 592 dm
on Wednesday as the ridge slightly weakens. The high pressure and
offshore winds will keep skies clear through the period.

The offshore winds will be the major story for the next two
days as they are in large part driving the temperatures. Current
gradients are -6.4 mb from kdag and -6.6 mb from kbfl. On Tuesday
the east to west kdag gradient is forecast to peak at -8.3 mb while
the north to south kbfl gradient weakens some to -4.9 mb. This
will switch the winds to more of an easterly direction. Winds will
peak Tuesday. There is little upper support so this will primarily be
a gradient-driven event and as such should keep wind below warning
levels. There will most likely be a few warning level gusts
across the ridgetops. Winds will diminish on Wednesday but will
remain at advisory levels until afternoon.

Very high heights (15 dm higher than normal) and offshore flow
will combine to bring record heat today, Tuesday (highs 95-105
common) and likely in to Wednesday. Uncomfortably warm nights
(65-75, some above 80) will raise the impact of this event. This
prolonged heat poses a concern for heat-related illnesses among
the vulnerable population, especially for the elderly and
children. Heat warnings advisories are in effect for much of the
area. Please see the product laxnpwlox for a detailed description
of all heat and wind warnings and advisories. Major fire concerns
exist as well (see fire weather section below).

Weaker offshore flow Wednesday along with lowering heights will
bring cooling to most areas, most significant north of point
conception and near the coast. However, temperatures will remain
well above normal with widespread 80s and 90s.

Both the GFS and the ec now agree that a tall and skinny 588 dm
ridge will set up on Thursday. Weak morning offshore and
afternoon onshore winds will allow for a good cooldown, but max
temps will be 6 to 12 degrees above normal over much of the area.

Long term (fri-mon)
the ridge will persist into Friday only to be replaced by a
smaller ridge poking in from the SW over the weekend. While it
doesn't look like the marine layer will return in strength over
the weekend, it does appear that the rh levels will finally rise
above the 10-20 percent levels with at least some high clouds
helping to cool things down. The jet drops down over our area on
Monday and that may finally be enough to get our pattern back to
more seasonal for late october.

Aviation 23 2350z...

at 2317z, there was a marine inversion at klax at around 200 ft
deep. The top of the inversion was at 1000 ft with a temperature of
35 deg c.

Hi confidence in the 00z tafs withVFR conditions at all airfields
thru Tue afternoon. There will be gusty NE winds at koxr and kcma
and gusty N winds at kvny later tonight and tue, strongest thru the
morning. Gusty NE winds can also be expected at kwjf and kpmd on
tue afternoon.

Klax... Hi confidence in the 00z TAF withVFR conditions expected
thru Tue evening.

Kbur... Hi confidence in the 00z TAF withVFR conditions expected
thru Tue afternoon. There is also a 50 percent chance of low level
wind shear at times thru Tue morning due to gusty NE winds just
above ground level.

Marine 23 200 pm.

For the outer waters, high confidence in current forecast. Winds
and seas are expected to remain below small craft advisory (sca)
levels through Friday for pzz670 673. For pzz676, there is a 60%
chance of SCA level northeast winds Tuesday and a SCA has been
issued.

For the inner waters, high confidence in current forecast. For the
waters north of point sal, winds and seas will remain below sca
levels through Friday. For the waters south of point conception,
sca level winds are likely from ventura south to santa monica
today through Wednesday with the strongest winds in the morning to
early afternoon hours. On Tuesday morning, there is a 40% chance
of gale force gusts, but the coverage of these gusts are expected
to be localized.

There is a chance that the northeast winds will reach avalon and
two harbors on Tuesday, but since this is a hot santa ana event
the likelihood of significant winds out that far is small. 30
percent chance of 10-20 kt winds in the harbors, 10 percent chance
of 15-25 kt.

Fire weather 23 100 pm.

A moderate to locally strong santa ana wind event will bring
windy, hot and very dry conditions through Wednesday to much of
los angeles and ventura counties. This event is especially
concerning because of the multiple day nature of it, which we have
not seen yet this season and such events have a history of large
fires. The winds will peak on Tuesday with 20 to 30 mph gusting to
50 mph common in the wind prone coastal and valley areas of los
angeles and ventura counties, and 20 to 35 mph gusting to 60 mph
common in the mountains. Minimum humidities of 6 to 12 percent
will be common through Wednesday, with poor overnight recoveries.

Widespread record breaking heat will exasperate the situation,
with highs between 95 and 105 common and lows between 65 and 75
common. Some windy and hilly locations may only drop into the 80s
at night. A red flag warning will remain in effect through
Wednesday as a result. Over san luis obispo and santa barbara
counties, similar heat and dry air is expected, but easterly winds
peaked on Sunday and should locally gust between 20 and 30 mph in
the wind prone areas. As such, elevated fire weather conditions
exist there.

With these prolonged weather conditions, and the very dry
fuels vegetation, extreme fire behavior is likely if any fire
ignition begins... Threatening life and property. The public
should be very, very careful with any potential ignition sources
such as welding and brush clearing equipment, as well as campfires
and cigarettes.

Lox watches warnings advisories
Ca... Heat advisory in effect until 8 pm pdt Tuesday for zones
34>36-39-88. (see laxnpwlox).

Excessive heat warning in effect until 8 pm pdt Tuesday for
zones 40-41-44>46-87-547. (see laxnpwlox).

Wind advisory in effect until 2 pm pdt Wednesday for zones
40-41-44>46-53-54-88-547. (see laxnpwlox).

Red flag warning in effect until 6 pm pdt Wednesday for zones
240-241-244>246-253-254-288-547-548. (see laxrfwlox).

Pz... Small craft advisory in effect from 2 am to 3 pm pdt Tuesday
for zones 650-655. (see laxmwwlox).

Hazard potential outlook (thu-mon)
heat advisory level temperatures may continue for many areas into
Wednesday. Gusty northeast winds will likely impact wind prone
areas of los angeles and ventura counties through early
Wednesday. Hot, dry and windy conditions will likely bring
continued critical fire weather conditions to some areas
Wednesday.
