Synopsis 15 234 pm.

Temperatures are much cooler across the region today and will
remain so through Friday then gradual warming begins next
weekend. Overnight and morning low clouds and fog will return to
most coastal and adjacent valley areas this week.

Short term (tdy-wed) 15 211 pm.

Regional temperatures continue to show strong cooling with many
double digit drops from yesterday and many drops of twenty degrees
or more along the central coast. Temperature MAX values were
tweaked downward to reflect the increased level of cooling but may
not have been enough in some locations. Winds are moderately
gusty particularly across los angeles county but nothing
approaching advisory levels.

As the first of two troughs approaches the region, onshore
gradients will continue to trend stronger and the marine layer
will deepen to near 1200 feet overnight south of point conception
and 1500-2000 feet along the central coast. Temperatures will
cool a few degrees more tomorrow and winds will become stronger
and more gusty and may reach advisory level in the Monday
afternoon through Tuesday morning time period. Advisory level
sundowners are possible during this period across santa barbara
county. Some convective clouds may percolate over the mountains
Monday afternoon and evening but lack of a deep mid level
moisture layer should keep the impact minimal. Will keep an eye on
it though as a twitch of parameters could bring downburst and dry
lightning conditions.

There will be an interlude between troughs Tuesday and midday
Wednesday. Temperatures will likely warm a degree or two in many
locations and the marine intrusion will ease a bit but otherwise
conditions will remain similar to Monday. The second trough will
begin to move through the region by late Wednesday, this will
deepen the marine layer and strengthen the onshore flow such that
the low clouds push into interior valleys.

Long term (thu-sun) 15 234 pm.

The brunt of the second trough will move through the region on
Thursday. With a stronger onshore flow and deeper marine layer
temperatures will cool a bit further and keep the autumn-like
conditions in place for a couple more days. The winds will also
strengthen and another shot of sundowners is likely Thursday
night. The trough not not particularly strong though, so no
showers should be generated however some morning drizzle is
possible.

After a cool Friday, a weak ridge develops Saturday and Sunday
and returns sunny skies and a warming temperatures to the region.

Temperatures will warm to near normal seasonal values at most
locations.

Aviation 15 2356z.

At 2240z, the marine layer at klax was 1200 feet deep. The top of
the marine inversion was near 2500 feet with a temperature of 26c.

Low clouds will spread across the coastal plain this evening, then
push into the santa ynez valley and probably the san gabriel
valley and lower valleys of vtu county after midnight. Low clouds
will likely push into the salinas valley by daybreak. Conds will
be mostly ifr to lifr, except locally vlifr on the central coast
and in the santa ynez valley. There is quite a bit of uncertainty
as to whether low clouds will push into the san fernando valley
overnight. Low clouds should clear by mid morning in the valleys
and by late morning on the coastal plain.

Gusty southwest to west winds will affect the mountains and the
antelope valley TAF sites Mon afternoon and evening.

Klax... Low to moderate confidence in the 00z taf. There is a
30-40% chance that CIGS will arrive as early as 02z this evening.

Kbur... Low confidence in the 00z taf. There is a 40% chance of ifr
cigs between 08z and 16z.

Marine 15 133 pm.

Moderate confidence in the current forecast. Higher confidence in
winds, less confidence in swells. Small craft advisory (sca) level
winds will likely develop through Monday evening over most of the
coastal waters. There is a 50 percent chance of SCA level winds
across the near shore waters north of point sal and 30 percent
chance across the inner waters south of point mugu. Periods of
steep seas will develop at times, especially across the northern
and inner waters.

Winds will likely diminish some between Tuesday and Tuesday
night, then winds will likely develop across the entire coastal
waters between Wednesday and Thursday.

A southerly swell developing with hurricane kiko will move over
the coastal waters between late Monday night and Wednesday. There
is a 40 percent chance that elevated surf of 3 to 5 feet could
break near shore and in the vicinity of jetties at times during
this period.

Patchy dense fog is possible across portions of the coastal
waters this morning. Visibility may be reduced to one nautical
mile or less at times through late this morning.

Beaches 15 1224 pm.

Hurricane kiko has strengthened to a major hurricane today.

Strong rip currents are possible at area beaches between Tuesday
and Wednesday. A high rip current risk is likely for this period.

There is a 50 percent chance that elevated surf between 3 and 5
feet is possible on Tuesday and Tuesday night. Before entering the
water, ask a local lifeguard about hazardous areas and the latest
swimming conditions.

Fire weather 15 334 pm.

An upper level trough of low pressure will continue to bring
strengthening onshore flow to the region through Monday. Onshore
winds are gusting between 25 and 40 mph across interior sections
today, and are expected to increase to 30 to 45 mph by Monday.

Temperatures across inland areas are in the 90s today, with cooler
temperatures on Monday. Meanwhile, humidities between 8 and 15
percent have been observed across interior sections today. By
Monday, the stronger onshore flow pattern combined with a
deepening marine layer will bring some humidity recovery to
coastal and valley areas, however a pocket of drier air will
remain in the la ventura county mountains and antelope valley
where humidities will range between 10 and 20 percent. The gusty
onshore winds combined with lingering dry air will bring elevated
to brief critical fire weather conditions to all interior areas
through this evening, then mostly confined to the la ventura
county mountains and antelope valley on Monday. There will also be
some mid level moisture and instability coming across the region
on Monday, which could produce a few sprinkles in the mountains
along with gusty erratic winds. At this time, the dry lightning
threat is less than 10 percent on Monday, but will continue to
monitor the situation.

There will be gusty northwest winds Monday night across western
portions of the santa barbara south coast and adjacent foothills,
but humidity levels are expected to high. Mild conditions are
expected across the region Tuesday through Thursday.
