Synopsis 15 712 am.

Conditions will be warm and dry today then cooler tomorrow.

Onshore flow returns this weekend and will bring overnight and
morning low clouds and fog to the coast and adjacent valleys into
early next week and near normal temperatures through the week.

Short term (tdy-sat) 15 312 am.

Three quiescent weather days lined up for the area.

Offshore flow is between 3 and 4 mb this morning and there are
some canyon breezes but without any upper support the winds will
not reach advisory levels. Skies are clear now but later there
will be a few high clouds drifting overhead in the SW flow aloft.

Hgts are near 579 dm. There will be decent onshore trends this
afternoon and this will bring in an earlier and slightly stronger
sea breeze which will cool the coasts and to a lesser degree the
vlys today. Away from the seabreeze the inland areas will warm a
degree or two.

Hgts fall overnight and the onshore trends continue. Pressure
grads will still be offshore though and this should be enough to
keep low clouds from forming across most of the area except for
the lax to long beach area.

The onshore trends and hgt falls should combine on Friday to bring
about 3 to 6 degrees of cooling to most coastal and vly areas.

Hgts change little and the inland area will not see much change in
the temperatures. Enough mid and high level clouds will be
embedded in the flow aloft to make skies partly cloudy.

The gradients turn neutral on Friday night and the low levels of
the atmosphere should moisten up enough to allow low clouds to
form across most of the coasts. There will be another 2 to 4
degrees of cooling under partly cloudy skies which is enough to
bring MAX temps down to normal levels. (there has only been one
other day this month (the 9th) with normal or below MAX temps)

Long term (sun-wed) 15 353 am.

Not much change on Sunday as non of the meteorological parameters
change much. The marine layer may be a little thick and more
widespread as more moisture entrains into the lowest levels.

On Monday a weak pop up ridge moves over the state in response to
an upper low plunging southward to the west of the coast. Healthy
offshore trends will lead to 2 to 3 mb of offshore flow in both
directions by mid morning. There is little or no upper support and
if this verifies the winds will not reach advisory levels. The
rising hgts and offshore flow will bring about 2 to 5 degrees of
warming.

Both the GFS and the ec show a dry trof moving through the area on
Tuesday and this will really lift the marine layer reverse the
offshore flow to onshore and lower hgts as well as bringing some
mid and high level clouds to the area. MAX temps will likely fall
the same 2 to 5 degrees they rose on Monday.

The long range mdls continue to struggle with pattern change
forecast next week. On Wednesday the GFS has more of a ridge while
the ec has a troffier solution. Either way not too big a change
and Wednesday should be similar to Tuesday.

The thanksgiving forecast is still pretty murky. The GFS is dry
will the ec has some light rain. The trends have all been to push
any precip to later in the week so thanksgiving should be dry.

Rain chcs improve on Friday and into Saturday.

Aviation 15 1731z.

At 17z at klax, there was no marine layer. There was a surface
based inversion with a top of 1000 ft and a temperature of 20c.

High confidence inVFR everywhere through this evening. Lifr fg
will likely form over the waters late tonight, with a 40 percent
chance of impacting klgb klax ksmo, and 20 percent chance at koxr
kcma ksba. Gusty NE winds will be weakening today.

Klax... High confidence inVFR through this evening. 30 percent of
lifr fg 12-17z Friday. High confidence in any east winds staying
under 7 kt.

Kbur... High confidence inVFR through Friday with light winds.

Marine 15 921 am.

High confidence in winds staying below small craft advisory (sca)
through at least the weekend. Dense fog with very low visibility
is possible late tonight and Friday, especially south of point
conception including the san pedro channel.

Lox watches warnings advisories
Ca... None.

Pz... None.

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.
