Synopsis 26 818 pm.

A warming trend will start today and persist through Thursday.

Night through morning clouds are expected to return to most
coastal areas by Tuesday. There is a slight chance of mountain
showers by midweek.

Short term (tdy-wed) 27 310 am.

Much quieter and a little more normal weather day on tap today.

Yesterday's upper low is pushing out of the state. Dry nnw flow is
setting up on its heals. Hgts will rise from the abnormally low
555 dm ydy to a still below normal but much more reasonable 568 dm
this afternoon. North flow has banked some clouds up against the
north slopes near the kern county line and there are some patch
low clouds across the central coast but otherwise skies were
mostly clear. MAX temps will be warmer than yesterday but will
still be about 12 to 15 degrees below normal (20 degrees blo
normal in the antelope vly)
a little eddy will spin up and along some warming aloft a decent
marine layer stratus deck will develop and will cover most of the
coasts and lower vlys.

There will not be enough onshore flow nor a strong enough
inversion to hinder the stratus dissipation and skies will be
clear by late morning. Aloft there will be 570 dm hgts aligned in
a northerly direction. There will be 3 to 6 degrees of warming but
max temps will still come in well below normal.

A little trof ripples through on Wednesday. It will not do much
much except to deepen the marine layer a little bit. Onshore flow
increase a little bit which should delay the stratus dissipation
by an hour or two. Temps will not change much near the coast but
inland most of the cool air will have modified and this will allow
for a healthy 6 to 8 degrees of warming. The trof will bring just
enough lift and instability to warrant a slight chc of tstms over
the vta northern mtns and the far eastern mtns of la county.

Long term (thu-sun) 27 330 am.

Both the GFS and the ec agree that an upper low will move into the
state on Thursday and then will open up into a quasi stationary
pos tilt broad trof Friday and remain there through Sunday. There
will be moderate onshore flow through the period.

Skies will remain mostly clear save for the typical night through
morning low cloud regime.

The little trof will allow for a slight chc of mtn tstms on
Thursday but otherwise there should not be any convection.

Hgts rise to about 577 dm Friday and then change little after
that. MAX temps will rise to near normal Thursday and then will
change little each day after that.

Aviation 27 0633z.

At 2345z at klax, there was no marine layer nor a sfc based
inversion.

Moderate confidence in tafs. There is a chc of MVFR CIGS at all
sites through 14z but most sites should have only sct conds
through the period.

Klax..Moderate confidence in taf. There is a 30 percent chc of
ocnl bkn025 conds through 17z. MVFR CIGS may arrive as early as
06z Tuesday. Good confidence in no east wind issues.

Kbur... Moderate confidence in taf. There is a 30 percent chc of
ocnl bkn025 conds through 17z.

Marine 26 817 pm.

For the outer waters, high confidence in current forecast.

Northwest winds will increase to small craft advisory (sca) levels
at times tonight for the southern waters zone (pzz676) and for all
the outer waters Monday through Friday with the occasional slight
lull during the overnight hours.

For the inner waters north of point sal, moderate confidence in
current forecast. Winds should remain below SCA levels tonight.

There is a 50% chance of SCA level winds each afternoon Monday and
Tuesday. For Wednesday through Friday, winds and seas are
expected to remain below SCA levels.

For the inner waters south of point conception, moderate
confidence in current forecast. There is a 70% chance of sca
level winds this afternoon and evening and a 50% chance of sca
level winds Monday afternoon and evening. For Tuesday through
Friday, winds and seas are expected to remain below SCA levels.

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.
