Synopsis
A weak trough of low pressure over the channel islands will
continue to keep a cooler than normal air mass in place through
midweek. A deep marine layer in place this morning will slowly
recede through late week as the trough exits the region on
Wednesday and high pressure aloft builds in for late week. A
significant warming trend is possible for next weekend.

Short term (tdy-wed)
a deep marine layer remains in place this morning. The latest fog
product imagery indicates low clouds and fog pushing well into the
valleys and coastal slopes this morning. The latest marine layer
depth from klax amdar soundings shows the depth currently up to
around 2800 feet deep. The deeper marine layer and stronger
onshore flow in place is due to a weak trough of low pressure
currently centered over the channel islands, or about 75 miles
west of los angeles. With the instability moving around the trough
aloft and the deep marine layer in place, patchy morning drizzle
cannot be ruled out, especially along the coastal foothills.

Clouds will struggle to clear today. If looking to view the
partial solar eclipse with proper protective gear, don't head to
the beaches as clouds will struggle to clear again today. Head
inland instead. The partial solar eclipse should begin a few
minutes after 9 am pdt, reaching maximum between 1016 and 1021 am
pdt. For los angeles county beaches, clearing might occur just as
the partial eclipse reaches its maximum. For ventura, santa
barbara, and san luis obispo counties, the beaches may remain
socked in for most of the eclipse and your best bet might be to
travel inland to catch the partial solar eclipse.

Slight chance pops remain in the forecast for the santa barbara
and ventura county mountains for this afternoon, but lower
confidence exists at this time. Model solutions continue to
suggest the area getting 'dry-slotted' as drier air wraps around
into the trough. In addition, the eclipse could reduce solar
insolation and retard the daytime heating somewhat.

Onshore flow will weaken over the next 24 hours and the marine
layer depth will thin as the trough of low pressure retrogrades
west. The trough center will wobble through the santa barbara
channel later this morning and retrograde off the coast to about
325 miles west of los angeles, or near 34n and 124w by Tuesday
morning. As the trough retrogrades, the marine intrusion will get
pulled back and start to recede through Tuesday. The best estimates
put the marine layer depth between 1000-1500 feet by Tuesday
morning, but low confidence should exercised in this pattern. The
trough will start to advance again across the offshore and coastal
waters early Wednesday morning, and likely move onshore near
point mugu early Wednesday morning. Gradients should start to
become strongly onshore for Wednesday as the trough moves over the
area.

Long term (thu-sun)
a significant pattern change is taking shape for late next week.

Model solutions are coming into agreement for a significant
warming trend after Thursday, peaking over the weekend and into
early next week. The forecast takes a warm stance over forecast
guidance as models increase 950 mb temperatures over the weekend.

Strong high pressure over the southeast united states today will
recenter into the desert southwest by the latter half of the week.

500 mb heights will start to climb substantially over southern
california between Friday and Sunday as the ridge center moves
from the bootheel of new mexico into western nevada. The forecast
leans the direction local temperatures studies, going up to 5
degrees over forecast guidance. The ridge position would also be
consistent for a monsoonal flow pattern to setup early next week.

Aviation 21 1010z...

at 1000z, the marine inversion at klax was based at 2800 feet. The
top of the inversion was 3600 feet with a temperature of 19
degrees celsius.

Overall, moderate confidence in 12z TAF package. MVFR conditions
across most coastal valley sites, except ifr conditions at kprb.

Expect these CIGS to dissipate around 17z across the valleys and
between 18z-22z for coastal sites. For tonight, inversion should
be a bit more shallow, but MVFR ifr CIGS will still develop across
coastal valley sites.

Klax... Moderate confidence in 12z taf. There is a 30% chance that
MVFR CIGS could linger until 20z. For tonight, return of MVFR
conditions could be + - 2 hours of current 02z forecast.

Kbur... Moderate confidence in 12z taf. There is a 30% chance that
MVFR CIGS could linger until 19z. For tonight, return of ifr cigs
could be + - 2 hours of current 07z forecast.

Marine 21 200 am...

for the outer waters, moderate confidence in current forecast.

Through Tuesday night, winds and seas will remain below small
craft advisory (sca) levels. On Wednesday, winds will increase
with a 40% chance of SCA level winds developing. For Thursday and
Friday, the winds will continue to increase with SCA level winds
likely.

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 Wednesday. On Thursday and Friday, SCA level winds
are likely each afternoon and evening. For the waters south of
point conception, winds and seas will remain below SCA levels
through Friday.

Lox watches warnings advisories
Ca... None.

Pz... None.

Hazard potential outlook (wed-sun)
a significant heatwave could develop this upcoming weekend and
continue into early next week.
