Synopsis 18 1051 am.

Temperatures will be cooler into midweek. Then from Thursday to
Saturday a warm up will occur in offshore flow and as a high builds
in. Fair skies are forecast into Sunday, except for an overnight
coastal marine layer. A low may approach on Monday that will deepen
the marine layer and bring above normal temperatures for next week.

Short term (tdy-thu) 18 954 am.

The upper level trough continues to push towards the forecast area
this morning. The lowering heights and thickness combined with a
very slight increase in onshore flow will result in high temps a
good 3 to 10 degrees cooler vs yesterday's readings, a trend that
has already started based on current observations. Warming trend
kicks in tomorrow after tonight's trough passage and also brings
weak offshore flow by Thursday. Coastal stratus was limited
overnight to the central coast as only a very weak eddy formed
south under a relatively weak inversion. No real change in the
low level flow tonight but local models do bring stratus into at
least the la county coast and possibly up into the ventura coast.

This will be in addition to another round of coastal stratus
poking its way into the santa ynez valley.

Sundowner winds across the western portion of the sba south coast
gusted into the upper 40s last night. No real change in the
situation for later today and tonight, if not slightly favorable
factors for winds at least that strong, so anticipate issuing a
wind advisory this afternoon for the sba south coast and western
santa ynez range.

***from previous discussion***

Long term (fri-mon) 18 316 am.

The ec and the GFS agree that a weak trof will roll through the
area on Friday. This should bring more low clouds to the coastal
areas in the morning. The GFS continues the offshore flow from the
east while the ec has a more typical (for a trof) onshore pattern.

Favored the ec and with low clouds and slightly cooler temps. If
the GFS is correct it will be sunnier and warmer than fcst.

Both mdls bring a ridge to the area on Saturday. The ec has higher
hgts but stronger onshore flow while the GFS has lower hgts and
weaker onshore flow. The ec would bring warming to the interior
and cooling to the coast and the GFS would be the exact opposite.

Continued to favor the ec for this forecast.

Both mdls show little change for Sunday and a persistent forecast
seems to be the best way to go.

A large trof sweeps into the CONUS from british columbia on Monday
and the bottom the trof just brushes eastern ca. It does not look
like it will affect the weather much. The ec is a little warmer
than the GFS and the forecast pretty much splits the difference.

There will be a continued night through morning low cloud regime
across most of the coasts with the vlys remaining clear.

Aviation 18 1841z.

At 1512z, the marine layer depth was around 600 feet deep at
klax. The top of the marine inversion was around 2800 feet with a
temperature near 21 degrees celsius.

Moderate-to-high confidence in the current forecast. Higher
confidence for inland terminals, less confidence for coastal
terminals north of point conception and los angeles county coastal
terminals.VFR conditions are expected throughout the period,
except for a chance of lifr to ifr conditions at coastal
terminals north of point conception and a slight chance of ifr
conditions at los angeles county coastal terminals after 09z.

Klax... There is a 20 percent chance of ifr conditions after 09z.

There is a 20 percent chance of east winds of 7 kt or greater wed
morning.

Kbur...VFR conditions are expected throughout the period. No wind
impacts are expected at this time.

Marine 18 920 am.

Small craft advisory winds and short-period seas will continue
through Wednesday night across the outer coastal waters. There is
a 20 percent chance of gales, especially near point conception,
this afternoon and tonight. Winds will push into the western
santa barbara channel and the near shore waters north of point sal
during the afternoon and evening hours.

Winds will diminish and seas will subside between Wednesday night
and Thursday night, then remain below advisory levels into late
week. There is a 50 percent chance of small craft advisory winds
and short-period seas lingering across the northern waters on
Thursday afternoon and evening.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect until 3 am pdt Wednesday for
zones 645-670-673-676. (see laxmwwlox).
