Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1112 PM PDT Mon Jul 5 2021

.SYNOPSIS...05/842 PM.

High pressure will build over the region through this week,
leading to warming temperatures each day, especially for regions
away from the coast. The warmest days will likely be Friday
through Sunday when excessive heat will be possible for interior
areas. Low clouds and fog will be confined to the coastal plain
and lower coastal valleys during the overnight and morning hours.

&&

.SHORT TERM (MON-THU)...05/844 PM.

Upper level high pressure system will dominate the West coast
weather picture the next few days. despite the very warm
temperatures across the mountains and deserts, the moderate to
strong onshore flow will help to moderate temperatures for
coastal and coastal valley areas. Current satellite imagery
showing low clouds and fog returning to coastal areas this
evening, and will likely spread into some coastal valley
areas overnight into Tuesday morning, as the marine layer
depth ranges between 1000 and 1500 feet. Areas above the
marine layer will see the most noticeable warming the next
few days, as triple digit heat becomes more widespread across
the interior valleys, lower mountains, and deserts by Wednesday
and Thursday.

Northwest pressure gradients are expected to increase on Tuesday
evening, likely bringing advisory level winds to the western
portion of the Santa Barbara south coast/foothills (mainly from
Gaviota to San Marcos Pass) where gusts between 35 and 45 mph
are expected. Otherwise, look for elevated to brief critical
fire weather conditions across the interior areas through the
remainder of the week due to the hot temperatures, low humidities,
and gusty onshore winds each days.

One other item to watch the next few days will be a potential
threat of monsoonal activity by Wednesday or Thursday. While we
have been advertising a 10 percent chance of storms developing
over the mountains and deserts each afternoon starting Wednesday,
the 18Z and 00Z NAM models have begun to show a weak easterly
wave with associated vort max that swings some mid level moisture
and elevated instability up the coastal waters from the southeast.
While it is still early and the threat is fairly small, will have
to monitor this situation closely as we may need to introduce a
small chance of elevated convection with the possibility of dry
lightning for coastal/valley areas (mainly Santa Barbara/San Luis
Obispo counties) and adjacent coastal waters (including the Santa
Barbara channel) from Wednesday night into Thursday.
Interestingly, the NAM has shown 2 model runs of MUCAPE values in
the 1000-1500 J/kg range along the Central Coast and adjacent
coastal waters during this time, indicative of that elevated
convective threat. Model cross sections and soundings also showing
an influx of mid level moisture during this time period, and the
weak wave and associated vort max may be able to provide enough
lift to initiate some elevated convection.

*** From previoud discussion ***

High pressure will dominate the West Coast the next several days.
However, moderate to strong onshore flow to the east will
maintain a steady flow of cooling sea breezes to areas west and
south of the mountains. As a result, for most of the population of
southwest California the next few days at least will be very
typical for early July. Night and morning low clouds and fog for
the coast and sunny skies inland. Temperatures near normal for the
coast a few degrees above normal for the coastal valleys.

A different story though for the far interior areas such as the
Antelope Valley, the interior mountain slopes, and interior SLO
County. The sea breeze won't have any cooling impacts there and
temperatures will be on a slow by steady climb up the next few
days and into the weekend. Should see daytime temperatures
approaching 105 for the AV by Wednesday. That's about 5-10
degrees above normal and close to excessive heat criteria.
However, given that we've already had a couple of these events
over the last month or so am inclined to hold off issuing any
headlines for now and reserving those for later in the week when
temperatures get closer to 110.

Locally gusty northerly Sundowner winds will returning to southern
Santa Barbara County, perhaps a little tonight across the far
western areas (well west of SB city and Goleta), but more so
Tuesday night when a low end wind advisory may be needed.

There's a non-zero chance of some convection by Thursday as
monsoon moisture inches closer to the eastern LA County line.
Models are pretty consistent showing most of it staying east but
it's close enough to keep an eye on as this is one parameter the
models typically have a difficult time with.

.LONG TERM (FRI-MON)...05/203 PM.

Interior temperatures will peak Friday through Monday as highs in
the AV climb to or slightly above 110. However, as will have been
the case during the week prior the natural air conditioning
system, AKA the onshore flow will keep areas closer to the coast
much cooler. While the warmest coastal valleys will likely get to
around 100 or a touch higher, the vast majority of the valleys
will top out in the low to mid 90s and most coastal regions will
stay in the 70s. So again this heat event will primarily impact
the far interior areas.

Will have to continue to monitor the monsoon flow through early
next week as the location of the high is favorable for moisture
advection from the southeast if a source develops.

&&

.AVIATION...06/0610Z.

At 0445Z at KLAX, the marine layer was 1000 ft deep. The top of
the inversion was 2500 feet with a temperature of 25 C.

Moderate confidence in coastal and vly TAFs. Flight Cat changes
could be off by +/- 1 hour.

KLAX...Moderate confidence in TAF. VFR conds could occur as early
as 1630Z or as late as 18Z.

KBUR...Moderate confidence in TAF. Cigs could arrive as early as
10Z or as late as 13Z. There is a 30 percent chc cigs could be
OVC006. Good confidence that VFR transition will occur 1530Z-
1630Z.

&&

.MARINE...05/1003 PM.

For the Outer Waters, high confidence in current forecast. Small
Craft Advisory (SCA) level winds will increase over all of the
outer waters, and seas will build to near 10 feet. Good
confidence in winds building to GALE FORCE level winds by Tuesday
afternoon, although the timing may be a little delayed for the
outer waters south of Point of Mugu. The GALE WATCH has been
converted to a GALE WARNING starting Tuesday afternoon through
Tuesday night. At least SCA level winds will persist through
Thursday, and there is a 40 percent chance of GALE FORCE gusts on
Wednesday and Wednesday night. By Friday, SCA level winds will
continue across the out, but will drop below SCA levels for the
waters south of Point Sal.

For the Inner Waters north of Point Sal, high confidence in
current forecast. Through tonight, winds and seas will remain
below SCA levels. For Tuesday and Wednesday, SCA level winds are
expected during the afternoon and evening hours. For Thursday and
Friday, winds and seas will remain below SCA levels.

For the Inner Waters south of Point Conception, high confidence in
current forecast and SCA through tonight. SCA winds will likely
reoccur Tuesday afternoon into Tuesday night. Winds and seas are
expected to remain below SCA levels Wednesday to Friday for the
southern Inner Waters.

.LOX WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
PZ...Small Craft Advisory in effect until 3 AM PDT Tuesday for
      zone 650. (See LAXMWWLOX).
     Small Craft Advisory in effect until 2 PM PDT Tuesday for

     Gale Warning in effect from 2 PM Tuesday to 3 AM PDT
      Wednesday for zones 670-673-676. (See LAXMWWLOX).

&&

.HAZARD POTENTIAL OUTLOOK (THU-MON).

Excessively hot conditions over the far interior areas is
likely by the end of the week, starting as early as Thursday then
continuing into the weekend. This will bring an increased risk
for heat related illness and elevated fire weather conditions.
