UPDATED AVIATION SECTION

.SYNOPSIS...14/346 AM.

Seasonal June conditions will continue through the week as at
least weak to moderate onshore flow continues, with night through
morning low clouds and fog across most coastal areas. Near to
slightly above normal temperatures will continue through early
next week, with minor afternoon heat impacts, before cooling down
during the middle of the week.

&&

.SHORT TERM (TDY-TUE)...14/751 AM.

***UPDATE***

Morning visible satellite shows marine layer clouds were a little
more expansive than yesterday across San Luis Obispo and western
Santa Barbara counties and less coverage across the LA Basin.
Surface obs and webcams showed some locally dense fog did develop
again, including the Santa Ynez Valley and the San Miguel to Paso
Robles areas where the low clouds did make it all the way south
through the Salinas Valley. Coverage of the dense fog was too low
to warrant an advisory.

The forecast is still on track for a few degrees (2-5F) of cooling
to afternoon temperatures compared to yesterday with latest
observed 24-hr temperature changes across most areas this morning
at around 2-8F cooler. Despite the cooling, high temperatures this
afternoon are still forecast to reach near to slightly above
normal, with mostly upper 70s to upper 90s away from the coast.

***From Previous Discussion***

Today is expected to look a lot like yesterday, although a deeper
marine layer along the Central Coast should limit dense fog
coverage this morning. One difference is the push of low clouds
seen as satellite into the Salinas Valley early this morning that
will make a run for Paso Robles. Near normal temperatures
(70s-80) are anticipated near the coast with temperatures 5-10
degrees above normal (80s-100) across interior mountains and
valleys. Typically breezy afternoon to evening onshore winds are
expected peaking in strength through favored corridors.

Slight offshore trends and enhanced ridging aloft will bring a
few degrees of warming into Monday and Tuesday with the potential
for moderate heat impacts to expand for warmer coastal valleys and
the interior. Although above normal temperatures will increase
heat stress during the day for those interior areas, good cooling
trends in the evening and especially overnight should limit
overall impacts and therefore the need for heat products. However,
those sensitive to the heat may want to consider avoiding peak
heat of the day and hydrate often.

The marine layer and associated night-to-morning low clouds may
be squashed to mainly coastal areas for Monday and Tuesday with
limited to no valley penetration, contributing to the
aforementioned warming trends most notably for coastal valleys.
Fog may become more widespread within the marine layer albeit with
limited concern for dense fog given continued onshore flow and
only weak ridging aloft.

.LONG TERM (WED-SAT)...14/521 AM.

A slow-developing trough will likely build into region Wednesday
or Thursday and bring moderate cooling trends away from the coast,
drastically reducing heat risk even to warmer interior areas.
Night to morning low clouds will likely continue, but expand well
into the coastal valleys and possibly some lower foothills.

The associated onshore push will support gusty onshore to
northwest winds nearing advisory levels for the interior,
possibly extending to southwest Santa Barbara. There may be a
period of enhanced fire weather concern on one or both of those
transition days (Wed/Thu) for far interior areas and maybe
especially at high elevations, which would be situated above the
expanding marine layer influence.

Looking further out, there`s a 50-60 percent chance of above
normal temperatures returning and perhaps becoming more widespread
during the early to middle part of next week as a ridge
potentially builds into the region.

.AVIATION...14/1803Z.

At 1708Z at KLAX, the marine layer was 1000 ft deep. The top of
the inversion was near 3000 ft with a temperature of 23 C.

High confidence in VFR TAFs for desert airfields (KPMD & KWJF).

Low to moderate confidence in remaining TAFs. Timing of CIG/VSBY
restrictions may be off 3 hours and flight minimums by one
category.

KLAX...Low confidence in TAF. Intermittent CIGs around 008 are
possible from 14/18Z-14/23Z as stratus hangs along coastline.
Thereafter, IFR CIGs 005-007 should arrive 15/05Z (+/- 2 hours).
Stratus could hang along coastline again 15/18Z - end of fcst pd.
No significant east wind component expected.

KBUR... Moderate confidence in TAF. High confidence in VFR
conditions through 15/08Z. 30% chance of LIFR CIGs 12Z-16Z.

&&

.MARINE...13/821 PM.

Moderate to high confidence in current forecast. Conditions are
generally expected to remain below Small Craft Advisory (SCA)
levels across the coastal waters through the forecast period.

Local gusts could reach 21 kts during the afternoon and evening
timeframe across the western Santa Barbara Channel, Santa Monica
Basin, and nearshore Los Angeles Harbor into the San Pedro Channel.

Patchy dense fog with visibility 1 NM or less is possible each
night to morning through at least Monday.
