Synopsis 18 751 pm.

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

Short term (tdy-tue) 19 257 am.

An upper level high is over the state. Hgts over socal are 595 dm
which is 6 dm above the normal hgts for august. On Monday the
upper high will shift towards the SE as trof moves into the pac
nw. By Tuesday the trof is over NRN ca and the upper high is over
nm.

The marine layer has been smooshed to under a 1000 feet and this
should keep it out of the san fernando vly and mostly out of the
san gabriel vly all of the coasts are covered by low clouds and a
few beaches will see delayed or possibly no clearing this
afternoon due to a strong inversion. There might be a little more
low clouds in the vlys Mon and Tue as the hgts lower and allow the
marine layer to rise some. But the grads are about the same so the
difference in the day to day marine layer cloud coverage will be
subtle.

Max temps will peak today. MAX temps across the coasts and vlys
will be tempered by the marine layer and will only be 2 to 4
degrees above normal. The mtns and inland areas... However... Will
be 8 to 10 degrees above normal due to the above normal hgts. Max
temps will fall 2 to 3 degrees on Monday as the upper high pushes
off to the east. On Tuesday the coasts and vlys will see little
change in temps while the inland areas cool another 2 to 3
degrees.

Overnight lows will remain about about 5 degrees above normal and
this along with the increased humidities will make the
temperatures feel worse.

Long term (wed-sat) 19 302 am.

The ec and GFS are in generally good agreement in the extended
period. Southern ca will be sandwiched between the upper level
high over nm and weak trofing over the pac nw. Hgts over socal
will be near 590 dm every day.

The weather will change little from day to day thru sat. The
marine layer pattern will remain in place for night and morning
low clouds and fog mainly along the coastal areas. Otherwise,
mostly clear skies will continue during the period. MAX temps
will continue to run a few degrees above normal. In addition,
above normal sea sfc temps will continue to bring above normal
humidities and overnight lows.

Aviation 19 1152z.

At 1100z at klax, the marine layer was around 1600 feet deep. The
top of the inversion was near 4200 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 16-17z this morning. 30% 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 Monday
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. 30% chance for ifr MVFR CIGS between
14-16z for kbur this morning. Similar confidence for tonight with
cigs and stratus coverage into Monday morning.

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

30% chance that CIGS could scour out + - 1 hour from 12z taf.

Also, 30% chance that MVFR CIGS could scour out briefly and return
through 17z this morning. Good confidence that any east wind
component will be under 6 kt.

Kbur... Moderate confidence in 12z TAF through 14z with 30% chance
for brief ifr MVFR cigs. After that high confidence forVFR conds
through 10z Monday morning. 30% chance for ifr MVFR CIGS between
10z-15z Mon morning.

Marine 19 346 am.

For the outer waters... There is a 60 percent chance of small
craft advisory (sca) level winds late this afternoon through this
evening between point conception and NW of san nicolas island
including the outer channel islands. Otherwise not expecting
another SCA for the outer waters except a 50 percent chance
Wednesday late afternoon through Wednesday night.

For the inner waters... Conditions are expected to remain below
small craft advisory level through Thursday, although winds will
increase to around 20 knots by Tuesday night.

Patchy fog will continue to form during the overnight and morning
hours in portions of the coastal waters through at least
Wednesday. Patchy dense fog will be possible N of point conception
at times as this occurs.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
