Synopsis 18 846 am.

Above normal temperatures inland and weak onshore flow will
continue through this weekend and into early next week, as high
pressure aloft continues to build overhead. Night to morning low
clouds and fog will return to some coastal areas and coastal
valleys through Sunday.

Short term (tdy-mon) 18 912 am.

The marine inversion this morning ranged from near 1000 ft deep at
vbg to near 2000 ft deep at lax. Low clouds were covering much of
the coast and adjacent vlys this morning, and are expected to clear
to or off the coast by midday. Otherwise, mostly sunny skies will
prevail across the region thru the afternoon, except for a few
afternoon CU buildups in the mtns and deserts. Temps today will be
several degrees above normal in all areas with highs in the 80s and
90s from the inland coastal areas to vlys and lower mtns, to low
100s in the antelope vly.

A 595-596 dm h500 high will prevail over central and SRN ca today,
then weaken thru Sun before moving E into az and nm for mon. The
marine layer pattern is expected to persist thru mon, with varying
amounts of night and morning low clouds and fog expected mainly for
the coastal areas and perhaps into some of the adjacent vlys.

Otherwise, mostly clear skies will continue across the region.

A typical diurnal wind pattern will prevail as well, with weak flow
during the night and morning, followed by locally gusty onshore
winds in the afternoon and early evening.

Temps will continue to be several degrees above normal across most
of the area on sun, then cool slightly but remain a few degrees
above normal on mon. Highs Sun should reach the 80s and 90s from the
inland coastal areas to the lower mtns, then fall to the 80s to mid
90s in these areas on mon. In the antelope vly, highs will be in the
101 to 107 degree range sun, and in the upper 90s to near 104 on
mon.

Long term (tue-fri) 18 321 am.

A very stagnant forecast pattern sets up next week with the upper
high to the southeast and a weak trof to the nw. Dry NW flow will
be over the state which will preclude any monsoon flow. MAX temps
will change little across the coasts where the night through
morning low cloud pattern will continue. The inland areas will
cool some on Tuesday as hgts fall but then will change little for
the rest of the week as the pattern remains static.

The above normal sea sfc temps will continue to bring above normal
humidities and overnight lows.

Aviation 18 1221z.

At 1100z at klax, the marine layer was around 1200 feet deep. The
top of the inversion was near 3600 feet with a temperature of 27
degrees celsius.

N of point conception... Moderate confidence with vlifr lifr cigs
at coastal TAF sites early becoming ifr briefly before becoming
vfr by 17-18z this morning. 40% chance that CIGS could scour out a
few hours earlier than 12z TAF suggest. High confidence forVFR
cigs at kprb this morning. Not much change expected and will
continue with persistence forecast for this evening through sun
morning.

S of point conception... Low to moderate confidence with high ifr
to low MVFR CIGS for coastal sites. Better confidence forVFR
conds for inland tafs. 20% chance for ifr MVFR CIGS between 14-16z
for kbur this morning. Similar confidence for tonight with cigs
and stratus coverage into Sunday morning.

Klax... Moderate confidence with 12z TAF for MVFR CIGS through 17z.

30% chance that CIGS could be at klax only briefly before scouring
out this morning. There is a 20 percent chc of ifr CIGS through
13z. Good confidence that any east wind component will be under 6
kt.VFR transition should occur within an hour of fcst.

Kbur... Moderate confidence in 12z TAF through 14z with 30% chance
for brief ifr MVFR cigs. After that high confidence forVFR conds
through 10z Sun morning. 30% chance for ifr MVFR CIGS between
10z-15z Sun morning. Good confidence thatVFR transition should
occur within 30 min of fcst.

Marine 18 901 am.

For the outer waters... There is a thirty percent chance of small
craft advisory (sca) level winds tonight and tomorrow night near
point conception and a thirty percent chance across all of the
outer waters on Wednesday night. Otherwise conditions will be
below SCA levels.

For the inner waters... There is a twenty percent chance of sca
level winds across the western portion of the santa barbara
channel late this afternoon and evening. Otherwise conditions
will remain below small craft advisory level through Wednesday.

Patchy fog... Locally dense... Will form in the overnight and
morning hours in portions of the coastal waters through Wednesday.

A south swell will result in hazardous conditions for mariners
through this evening, particularly near the surf zone.

Beaches 18 850 am.

Elevated surf will continue at southern california beaches through
this evening as a long-period southerly swell moves across the
coastal waters. Strong rip currents and sneaker waves will be
common, especially across south-facing beaches.

Moderate to strong rip currents and sneaker waves could linger
into Sunday as the southerly swell will be slow to diminish.

Swimmers and anyone in the surf zone should remain vigilant
through the weekend.

Lox watches warnings advisories
Ca... Beach hazards statement in effect until 9 pm pdt this evening
for zones 40-41-87. (see laxcfwlox).

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
