Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
925 AM PDT Wed May 13 2020
.SYNOPSIS...13/924 AM.
Skies will be mostly clear save for some morning low clouds.
There will be gradual warming through Saturday. Gusty northerly
winds through the mountains and below the passes each night
tonight through Friday Night. Cloudier and cooler starting Sunday.
&&
.SHORT TERM (TDY-FRI)...13/923 AM.
Really only somewhat impactful weather issue next few days is the
Sundowner winds across srn SB County. It was breezy there last
night with the usual hot spots seeing gusts into the low 40s. As
models have been suggesting gradients and winds still strengthen
today and again tomorrow leading to stronger and more widespread
advisory level winds across that area. This is a more of a
northwesterly event, so not quite as favorable for the eastern
areas like Montecito and the I5 corridor but it will still be
breezy there. So an advisory will be issued shortly for later this
afternoon and evening and continuing through Friday morning with
the typical mid morning through early afternoon lulls.
Otherwise, as noted previously the cold front yesterday wiped out
the inversion and basically dissipated the clouds in many areas
except for interior SLO County and the region bordering Kern
County from the California Valley through Gorman. Expect that will
be the case again tonight, though possibly somewhat better
coverage in srn LA County than this morning. Temps will begin a
slow warm up through the end of the week as the southwest onshore
flow (represented best by the LAX-DAG gradient) weakens and weak
ridging aloft replaces the trough.
.LONG TERM (SAT-TUE)...13/312 AM.
Hgts peak near 580 DM on Saturday as a little ridge noses in from
the SW. The W/E grad remains about the same but the N/S grad will
be a little more onshore. While the SBA south coast and some areas
in the Santa Clarita Vly will cool due to the weaker northerly
flow most other areas will warm a degree or two making Saturday
the warmest day of the next 7.
A strong and cold (for mid May) upper low comes barreling into the
west coast on Sunday. Lowering hgts and increasing onshore flow
will gin up a good sized marine layer stratus blanket which will
cover most of the coasts and vlys. The upper low will actually
bring enough lift and moisture to warrant a slgt chc of rain over
SLO county. Max temps will begin to cool but will still mostly end
up above normal.
The upper low will move over Eureka on Monday. Strong SW flow will
set up over the area. Skies will be mostly cloudy over SLO and
most of SBA county while areas south of Pt Conception will see
partly to mostly cloudy skies depending on how much mid and high
clouds are embedded in the flow. Can't rule out some light rain
over SLO and northern portions of SBA county but if any rain falls
it will be minimal. Max temps will cool into the 70s across all of
the coasts and vlys.
Tuesday will be mostly sunny and dry. Brisk NW flow behind the
departing upper low will likely bring another round of N winds to
the area. Max temps will cool a few more degrees.
&&
.AVIATION...13/1213Z.
At 0930Z at KLAX...There was a 3600 ft moist layer with no
inversion.
Moderate confidence for coastal and valley TAFs, and high
confidence for desert TAFs. North of Point Conception, moderate
confidence in periodic MVFR cigs through 16Z-18Z. There is a 30%
chance cigs could be IFR or lower. South of Point Conception, good
confidence in VFR conditions, but there is a 20% chance of MVFR
cigs anywhere through 17Z. There is a 20% chance of a BKN050 deck
18Z-00Z at all sites. Good confidence in low clouds for
coastal/valley sites tonight, but low confidence in timing.
KLAX...Moderate confidence in TAF. There is a 20% chance of MVFR
conditions through 17Z. There is a 20% chance of BKN050 18Z-00Z.
Any east wind component will be 4 KT or less.
KBUR...Moderate confidence in TAF. There is a 20% chance of MVFR
conditions through 17Z. There is a 20% chance of BKN050 18Z-00Z.
&&
.MARINE...13/923 AM.
Once again, the NAM12 is having difficulty in selecting which
afternoon and evening will exhibit the strongest north to
northwest winds as the 12z run has greatly increased the winds
across the coastal waters south of Point Conception for late this
afternoon into tonight. The winds have increased so much for this
afternoon and evening that it was necessary to raise a Gale
Warning for PZZ673 and PZZ676, a Gale Warning for PZZ650, and a
Small Craft Advisory for PZZ655.
North of Point Conception, the highlights were not changed yet,
but it may be necessary to raise a SCA for this afternoon and
tonight in zone 670. There is a 30 percent chance of a SCA for
zone 645 for this aft6ernoon and evening.
