431 pm pst Mon dec 10 2018

Synopsis 10 331 pm.

A weak cold front will cross the area through tomorrow morning,
bringing isolated rain and snow showers to the north slopes of the
la and ventura county mountains. A ridge of high pressure will
build into the area behind the front, with gusty offshore winds
and above normal temperatures by Thursday. A low pressure system
will bring a chance of rain to the area on Sunday.

Short term (tdy-thu) 10 216 pm.

High clouds continue to stream overhead from the southwest. These
will start clearing out overnight as the moisture plume shifts to
the east leaving behind mostly clear skies. One possible
exception to this could be southern la county where the NAM shows
low level moisture increasing beneath a solid inversion based at
just under 1000'. Given the amount of high level moisture moving
through the inversion may not have enough time to develop to allow
lower clouds to form so confidence in stratus formation tonight
is lower than usual. Either way, only southern la county would
likely be affected. There also could be some upslope clouds and
possibly even some light precip along the north facing mountain
slopes near the grapevine later tonight. Elsewhere there will
enough north to northeast flow to keep clouds away from the coast.

In fact, northerly winds may get close to advisory levels across
srn sb county this evening but these would likely be higher up in
the hills.

Sunnier days on tap Tue and Wed except the previously mentioned
possibility for early morning low clouds in la county. Temps
within a couple degrees of today except some local warming
possible in SRN sb county due to the downslope winds. Main issue
through mid week will be the north winds which are expected to
increase Tue and Wed and likely result in more widespread advisory
level speeds. This would include SRN sb county, the i5 corridor,
and possibly even some of the higher valley locations.

A more traditional inside slider Thursday will lead to an increase
in offshore gradients and northeast winds. Latest model guidance
shows a lax-dag gradient of -6.3mb with some (though not ideal)
support aloft. This may be a low end advisory level santa ana
event for la ventura counties. Temps for coast valleys will warm
up in the mid to upper 70s while higher mtns and deserts will
cool slightly with the cold air advection.

Long term (fri-mon) 10 207 pm.

On Friday gradients start trending onshore ahead of a trough
approaching into the west coast. Temps will cool a few degrees
near the coast but ridging aloft will allow interior temps to
warm up. A weakening cold front associated with the trough may
hold together just long enough to drop some light rain across
northern slo county Friday evening but dry conditions expected
elsewhere.

A brief ridge will develop over the area Saturday under light
onshore flow. Could be some patchy marine layer clouds over the
weekend but otherwise pretty quiet weather through early Sunday.

A stronger trough will move in late Sunday with a better chance of
rain for areas north of pt conception Sunday afternoon and
evening. Further south the chances are not quite as good as the
gfs is showing little if any southerly low level flow after the
front moves past pt conception which isn't a favorable scenario
for rain. But there may be just enough energy associated with the
upper level system to drop some light showers through la county
overnight.

Either way, skies will clear out by Monday morning with sunny,
dry, but cool weather Monday.

Aviation 11 0031z.

At 0010z, there was no marine layer at klax.

Two coastal locations have the potential to see a return in marine
layer clouds tonight. The central coast has a slight chance of
marine clouds tonight with lifr conditions and kprb should see
dense fog once again.

The south portion of the coast in the vicinity of klax ksmo and
klgb will also have a slight chance of marine clouds with lifr
conditions forming late tonight.

Elsewhere,VFR conditions are expected to continue for the next 24
hours.

Klax...VFR conditions are expected through at least 10z. There is
a 50 percent chance of lifr conditions Tuesday morning. There is a
20 percent chance of east winds of 7 knots or more.

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

Marine 10 1241 pm.

Moderate confidence in the marine forecast.

The outer waters have SCA posted through Tuesday night and it may
be necessary for an extension at some point through Wednesday
evening.

The inner waters along san luis obispo coastline will see either
hazardous seas or brief periods of gusty winds so the SCA will
continue there through Tuesday morning.

The santa barbara channel will have local gusts to 25 kt in the
western portions in the afternoon and evening. Otherwise, winds
will remain below SCA criteria.

Beaches 10 1050 am.

A high surf advisory remains in effect for the beaches along the
central coast and ventura county. Local advisory sets are possible
at west facing beaches along the south coast of santa barbara
county, such as rincon point and county line this afternoon and
tonight.

An extended period of high surf is expected at central coast
beaches for the latter part of the week. Very large and
potentially damaging surf could develop over the weekend and into
early next week with energy possibly pushing into southern
california bight early next week.

Lox watches warnings advisories
Ca... High surf advisory in effect until noon pst Tuesday for zones
34-35. (see laxcfwlox).

High surf advisory in effect until 6 pm pst Tuesday for zone
40. (see laxcfwlox).

Pz... Small craft advisory in effect until 9 am pst Tuesday for
zone 645. (see laxmwwlox).

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

Hazard potential outlook (thu-mon)
Gusty advisory level north to northeast winds are expected
early Thursday. High surf and dangerous rip currents are expected
on the central coast Thursday through Saturday, possibly
expanding to most beaches on Saturday and continuing through
Monday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
