What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Los Angeles, CA wrote its last area forecast discussion before this small craft advisory went out at May 22, 11:36 PM PDT, 3 hours 44 minutes earlier.
Area forecast discussion, May 22, 11:36 PM PDT, 3 hours 44 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1136 PM PDT Sat May 22 2021
.SYNOPSIS...22/723 PM.
An area of low pressure aloft will move east of the area and
bring a warming trend through Monday. Onshore flow will weaken
over the coming days and night through morning low clouds will
become confined to the coast, then a cooling trend will commence
as broad troughing develops. A warming trend is possible next
weekend.
&&
.SHORT TERM (SAT-TUE)...22/843 PM.
Upper level low pressure system now centered across the southern
Great Basin, with northwest flow aloft across Southwest
California. Upper level ridging will build into California
on Sunday, with increasing heights across the region. This will
lead to warming and drying across the forecast area, especially
inland areas where high temperatures will climb into the mid 70s
to around 80 degrees. Current satellite imagery showing low clouds
and fog off the Central Coast and is expected to push inland tonight
into the Santa Ynez Valley. Also, expecting low clouds and fog to
develop across portions of the LA basin and Salinas Valley overnight
into Sunday morning.
Some gusty sundowner winds returning this evening across western
portions of the Santa Barbara south coast and foothills, with
gusts ranging between 30 and 40 mph from Gaviota to San Marcos
Pass. At this time, thinking that the winds will be too localized
for any wind advisory issuance. Santa Barbara-Santa Maria gradient
peaked at -3 mb this evening. Somewhat stronger and more
widespread sundowner winds are expected during the late afternoon
and nighttime hours from Sunday through Tuesday. The Santa
Barbara-Santa Maria pressure gradient is expected to peak around
-4 mb each evening with moderate upper level level wind support.
As a result, expecting winds gusts in the 35 to 45 mph range each
night from Gaviota to San Marcos Pass, with isolated gusts as high
as 50 mph near the hills above Gaviota and Refugio. Each night,
sundowner winds are also expected to spread eastward into the hills
above Montecito and Carpinteria with gusts in the 25 to 40 mph range.
The gusty winds combined with humidities in the 20 to 40 percent
range will bring elevated fire weather conditions to southern
Santa Barbara county from late Sunday afternoon through
Tuesday night.
*** From previous discussion ***
Upper level ridging should continue to build into the area Sun
night and Mon, with H5 heights increasing further to around
580-581 by Mon afternoon. There should be some low clouds
affecting the Central Coast Sun evening, but should be pushed off
the coast by later Sun night thanks to increasing offshore flow.
Some low clouds and possible dense fog cannot be ruled out for the
southern L.A. County coast Sun night into early Mon morning, but
these should quickly dissipate by mid morning Mon. Otherwise,
mostly clear skies will continue across the region thru Mon.
Morning offshore flow and much warmer boundary layer temps will
boost temps significantly on Mon. Most areas away from the coast
will be several degrees above normal on Mon, with highs in the
warmest vlys and lower mtns expected to reach the mid 80s to low
90s.
Offshore gradient trends will increase Sun night into Mon both to
the N and E, which will contribute to increasing N to NE flow
across the region into Mon morning, especially for inland areas
and foothills. There should be a round of gusty NW to N canyon
winds across southern SBA County Sun evening, then gusty NE winds
should develop over the foothills and mtns of SLO/SBA Counties and
into VTU/L.A. Counties later Sun night into Mon morning. However,
gradients will not support winds reaching Advisory levels. Winds
should then turn around and become breezy onshore for many areas
by late Mon afternoon.
Very weak upper level troffiness should move into srn CA Mon
night and Tue, with H5 heights over the forecast area lowering to
around 576-578 dm by late Tue. Low clouds and fog should affect
the VTU/L.A. County coast and into the San Gabriel Vly Mon night
into Tue morning, otherwise clear to partly cloudy skies should
prevail across the region thru Tue. Temps should be cooler on Tue
and be closer to normal to a few degrees above normal. For the
warmest vlys, lower mtns and deserts, highs are expected to reach
into the 80s.
.LONG TERM (WED-SAT)...22/154 PM.
The deterministic EC and GFS are in generally good agreement Wed
thru Fri then differ in the upper level pattern for Sat. Very weak
upper level troffiness with slowly rising H5 heights can be
expected into Wed. Generally flat upper level ridging can be
expected over SW CA for Thu and Fri, with H5 heights generally in
the 581-583 dm range. For Sat, the EC moves and upper level trof
into the region from the W, while the GFS forecasts and much
weaker upper level trof off the coast. The mean ensembles both
show an upper level trof over CA for Sat, with the EC slightly
stronger (H5 heights over the fcst area around 574-576 dm). Either
model solution would not have much difference in the overall
fcst.
It looks like the marine layer pattern will persist over the
region with varying amounts of night and morning low clouds and
fog for the coast into some of the vlys, otherwise skies should be
clear to partly cloudy. Breezy to gusty onshore winds can be
expected each afternoon and evening, altho for southern SBA
County, breezy to gusty NW-N canyon winds should affect the area
most evenings, especially west of Goleta. Temps are forecast to
have little day to day change Wed thru Fri then turn cooler on
Sat. Overall, inland areas should be near normal to a few degrees
above normal thru Fri then turn slightly below normal Sat. For
coastal areas, highs should generally be several degrees below
normal each day.

top of the inversion was near 2700 feet with a temperature around
11 degrees Celsius.
Good confidence in TAFs for KSBA, KBUR, KVNY, KPMD and KWJF.
Moderate confidence in remainder of TAFs. There is a 20 percent
chc that there will be no low clouds across the LA county coast.
There is a 30 percent chc KCMA and KOXR will be SKX by 11Z. Flight
Cat transtions may be off by an hour.
KLAX...Moderate confidence in TAF. There is a 20 percent chc of no
cigs. Cigs could arrive as late as 12Z. VFR transition could occur
as early as 16Z. Any east wind component will be less than 5 kts.
KBUR...Very good confidence in TAF.

.MARINE...22/822 PM.
Across the outer waters, SCA winds will continue through late
tonight across the southern two-thirds of the outer waters. SCA
level winds are expected to develop across the entire outer waters
Sun afternoon, likely continuing thru Wed. There is a 20-30%
percent chance of Gale force winds late Mon thru Tue night.
Across the inner waters N Pt. Sal, winds and seas are expected to
remain below SCA level thru Sun morning. SCA level NW winds are
expected during the afternoon and evening hours Sun thru Tue, then
there is a 40% chance of SCA level winds Wed afternoon.
In the Santa Barbara Channel, W-NW SCA level winds are expected
to continue thru tonight across western portions. SCA level winds
are likely in the afternoon/evening hours Sun thru Wed.
For the southern inner waters (PZZ655), SCA conditions are not
expected from late tonight thru Mon morning. There is a 30% chance
of SCA level winds Mon afternoon/evening, then SCA level winds
are likely Tue afternoon/evening. SCA conditions are not expected
Wed.

.BEACHES...22/846 PM.
The combination of large, steep wind waves and a long period
south swell will create elevated surf and a high risk of
dangerous rip currents on most beaches of southwest California
beaches through Sunday morning. Refer to the Beach Hazards
Statement (LAXCFWLOX) for additional information.
