Synopsis
A weak trough on Monday may bring a few light showers over san
luis obispo and santa barbara counties as well as the north
slopes. Strong gusty north winds will begin Monday night and
persist into Tuesday. Weak ridging aloft will bring warm and dry
conditions for the middle of next week.

Short term (tdy-wed)
satellite imagery showing low level stratocumulus clouds
across the region this afternoon, along with increasing
mid and high level clouds streaming in from the northwest.

Weakening cold front on target to bring a slight chance of
showers to areas north of point conception later tonight, with a
better chance of showers across the interior mountains of
sba/ventura/la counties on Monday.

Strong wind event still on track for Monday evening into Tuesday
morning. High wind watches in effect for the mountains, santa
barbara south coast, and santa clarita valley where damaging wind
gusts of 60 mph or greater will be possible. Leading up to this
strong wind event will be increasing west to northwest winds on
Monday afternoon, resulting in wind advisories issued for the
above mentioned locations, as well as the central coast and
antelope valley (with gusts in the 40 to 50 mph range). By Monday
night (during the peak of the event), the flow will turn more
northerly, with wind advisories likely being needed for the san
fernando valley, foothills of the san gabriel valley, ventura
valleys, santa monica mountains, and los angeles coast as we draw
closer to the event.

The offshore flow will bring a warming trend on Tuesday, with
the warmest valleys expected to climb into the lower 80s. The
warmest day of the week for many areas is expected to be Wednesday
when increased offshore flow at the surface and stronger upper
level ridging combine to bring temperatures approaching 90 degrees
in the warmest valleys.

Long term (thu-sun)
an inside slider will move down the nv/ca state line Thursday and
then into arizona on Friday. Still a bit questionalbe how much
cooling this system will bring to the region as GFS maintains
higher heights than ec during this period. GFS and ec models
coming into better agreement on bringing a resurgence of offshore
flow and warming temperatures next weekend, with inland areas
climbing well into the 80s.

Aviation 26/1615z...

at 1600z, the marine inversion at klax was based at 4500 feet. The
top of the inversion was 6000 feet with a temperature of 9 degrees
celsius.

Overall, moderate confidence in 18z TAF package. Current cig and
vsby restrictions are expected to dissipate within the next couple
of hours withVFR conditions anticipated through this evening.

Overnight, will bring in a MVFR cloud deck to all coastal/valley
taf sites, but with low confidence as there is a 50% chance that
conditions could remainVFR.

Klax... Overall, moderate confidence in 18z taf. High confidence in
vfr conditions developing this afternoon. For tonight, low
confidence in development of MVFR CIGS (as there is a 50% chance
conditions will remainVFR).

Kbur... Overall, moderate confidence in 18z taf. High confidence in
vfr conditions developing this afternoon. For tonight, low
confidence in development of MVFR CIGS (as there is a 50% chance

Marine 26/100 pm...

for the outer waters, high confidence in current forecast.

Northwest winds will be on the increase through Monday night
with gale force winds likely Monday afternoon and night.

Winds will diminish a bit Tuesday/Wednesday, but will still remain
at SCA levels. For Thursday and Friday, there is a good chance
that winds will increase to gale force again.

For the inner waters, moderate to high confidence in current
forecast. For the waters north of point sal, high confidence in
winds reaching gale force Monday afternoon/evening with winds
hovering around SCA levels Tuesday through Friday. For the waters
south of point conception, moderate confidence in winds increasing
to gale force levels Monday afternoon and night (mainly across

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
