.SYNOPSIS...12/759 PM.

Temperatures will increase each day into mid-week, resulting in
widespread Moderate to Major HeatRisk Tuesday through Thursday.
Monsoonal moisture moving over the area will add to the
discomfort, also bringing the potential for showers and
thunderstorms each day, highest in the mountains.

&&

.SHORT TERM (SUN-WED)...12/903 PM.

***UPDATE***

CLouds continue to move northward over the region in a stream of
subtropical moisture originating from Mexico and the Gulf of
California. Satellite derived PW values over land are between 1 to
1.3", and up to 1.5" over the waters south of LA County. Some
isolated light showers have affected the area, with some
locations seeing a trace of very light rain, but with 0.01 to
0.03" along the Central Coast of Santa Barbara County and northward.
Diminishing shower chances are expected overnight into early
Monday, mainly over the mountains, and with very light or no rain
expected to hit the ground.

Cloud cover over much of the area helped to moderate the muggy
conditions resulting from the subtropical moisture and warm
temperatures. Highs today were mainly in the 70s along the coast,
with 80s to 90s further inland through the far interior. Onshore
winds gusting 20 to 35 mph affected interior sections today,
strongest through passes and canyons into the Antelope Valley.

Hot and muggy conditions are expected through the week. A strong
upper level high has shifted from the Four Corners Region northward
across Wyoming and the northern plains. The location of the high
will help to pull ample subtropical moisture into the area,
resulting in a risk of showers and thunderstorms at times at least
through the short term. The best chances of this occuring will be
over the mountains and deserts, Monday and Tuesday in the
afternoon hours. Temperatures will rise through the short term,
peaking on Wednesday with many locations over 100 degrees and up
to 110 degrees. Weak offshore gradients will shut off the typical
sea breezes, and work to enhance the heating caused by strong high
pressure aloft over the area.

***From Previous Discussion***

High confidence that Extreme Heat Watches will become Warnings on
Tuesday for most areas except possibly along the immediate coast
and continuing through Thursday, though there is a 20-30% chance
that warnings will extend to the coast as well, especially the
Santa Barbara South coast where hot and strong Sundowners are
expected to peak Tuesday and Wednesday evenings. This could bring
temperatures at the beach into the 90s with very warm overnight
temperatures as well. Current projections indicate a 30-40% chance
of 110 degrees in the western San Fernando Valley and close to
that in the southern Salinas Valley on Wednesday. There is a
60-80% chance of 95 or higher in Downtown Los Angeles. Given the
extreme heat and humidity it`s highly recommended to complete
outdoor activities as early as possible.

.LONG TERM (THU-SUN)...12/158 PM.

High pressure will begin to slowly weaken Thursday as a low
pressure system moves into the Pac NW. In addition, onshore flow
will return much earlier in the day bringing temperatures back
down to within a few degrees of normal in most areas by Friday.

However, one factor to keep a close eye on will be the next
tropical system off the coast of Mexico this weekend. While the
storm is expected to weaken considerably as it moves northwest,
there is a chance of another tropical moisture surge across the
area. Models are indicating PW`s increasing again to around 1.5"
as early as Saturday and remaining high into early next week. At
the very least there will be some increasing mid level clouds
along with higher humidities. But also can`t rule out isolated
showers and/or thunderstorms. Temperatures are expected to remain
within a few degrees or normal, but the increase in humidity could
lead to an increase in heat risk. And there will likely be some
increase in south swells as well.

.AVIATION...13/0055Z.

At 0014Z at KLAX, the marine layer was 800 ft deep. The top of
the inversion was at 2600 ft with a max temperature of 26 C.

High confidence in TAFs for KPMD, KWJF, KBUR, KVNY and KPRB.

Moderate confidence in the remaining TAFs. Mid and high clouds
will likely continue to disrupt the marine layer cloud formation
tonight, and any cigs that do form (30-40% chc) are likely to be
patchy and scatter and reform frequently later tonight into Mon
morning.

KLAX...Moderate confidence in TAF. There is a 30% chance of
BKN010-25 CIGs between 09-17Z Mon. High confidence that any east
wind component will be below 6kt.

KBUR...Moderate to High confidence in TAF. There is a 10-20%
chance of brief OVC008-015 cigs 12Z-16Z Mon.

&&

.MARINE...12/829 PM.

For the outer waters, winds and seas are expected to be below
Small Craft Advisory (SCA) levels through Tuesday morning. Then
there is a 50%-60% chance of SCA winds and seas developing late Tuesday
afternoon and continue through Thursday night or Friday morning,
with a 20% chance of Gale Force winds Wednesday. Thereafter,
conds will be below SCA levels Friday afternoon through the
weekend.

For the nearshore waters along the Central Coast, mainly light
winds are expected through Tuesday morning, then increase to SCA
levels Tuesday afternoon and persist (60% chance) through Thursday
night. Seas will increase to SCA levels Wednesday through
thursday. Conds should then drop below SCA levels late Thursday
night through the weekend.

For the inner waters south of Point Conception, conds are
expected to remain below SCA levels through the forecast period,
except for a 60% chance of SCA level wind gusts over the western
portions of the Santa Barbara Channel during the afternoon and
evening hours Tuesday through Wednesday.

Monsoonal moisture is expected to push over the coastal waters
during the next couple of days. As a result, there is a 10% of
isolated showers and thunderstorms over the coastal waters
through Tuesday. Any thunderstorm that develops could produce
dangerous cloud-to- ocean lightning.

&&

.BEACHES...12/830 PM.

A longer period, south to southwest swell will continue to affect
the coastal waters through this week. With this longer period
swell, the potential for larger surf and a greater risk for rip
currents will continue.

Evening high tides are expected to increase this week with Monday
expected to be the highest tide of 7.1 to 7.7 ft above MLLW.
There is the potential for some minor coastal flooding with the
evening high tides and south swell. One thing that will need to be
watched late this week into the weekend will be the potential of
a greater south to southwest swell from potential tropical cyclone
over the eastern Pacific.

In addition, a non-zero chance of thunderstorms will be possible
along the beaches at times into Tuesday (around a 10% chance
overall), and again late week into the following weekend. Any
thunderstorms that develop could produce dangerous cloud-to-ground
lightning. For more information, please refer to the Beach Hazard
Statement.
