Synopsis 22 752 pm.

Saturday morning will be cold with possible frost, but dry
conditions are expected for the day. Temperatures gradually warm
through early next week as dry weather persists. There is another
chance of light rain by mid-week.

Short term (tdy-mon) 23 257 am.

Clear skies and light winds have again allowed for good overnight
cooling and most areas will wake up to temps in the 30s.

Synoptically not too much excitement as dry NW flow shifts to the
west as it is pressed downward by a cold upper low pushing in to
washington st from british columbia.

Hgts do not change that much but there will be a slow warming
trend through the period as the airmass modifies. MAX temps will
remain below normal. (every day save one has had below normal max
temps this month) there should be just enough warming to preclude
any frost advisories tonight.

Skies will be mostly clear today. Sunday now looks a little less
cloudy than it once did as a storm that was forecast to skirt just
to the north is now forecast to arrive further to the north. A
second system will take a more southern trajectory not enough to
bring rain but enough to increase the mid and high level clouds
across the northern portion of the forecast area.

Long term (tue-fri) 23 314 am.

Both the GFS and the ec agree that the flat westerly flow will
continue on Tuesday. At one point it looked like there was a going
to br a little impulse in this flow but now all it looks like it
will do is bring in some more mid and high clouds. MAX temps will
still be blo normal but not by much.

In the predawn hours Wednesday a weak impulse rotating around an
upper low parked to the west of seattle will approach the central
coast and will then move through the area during the day. Its over
ocean trajectory will allow it pick up some moisture. Still it
does not have much in the way of dynamics. The best dynamics are
north of pt conception and there will be a chance of rain there
through the day. It looks like it will not be able to round pt
conception and vta and la county should remain dry. Clouds will
likely clover most of the area. MAX temps will slip a few degrees
due to the clouds.

Some showers may linger into Thursday morning ESP if the gfs
verifies.

Both mdls develop a ridge for Thursday although the warmer ec
develops it about 12 hours earlier. There should be clearing
skies. The sunshine and the rising hgts will combine to bring
several degrees of warming to the area and in fact MAX temps could
reach normal.

The ridging persists into Friday. An approaching system will push
plenty of mid and high level clouds into the area and this will
cool temps a couple of degrees.

Both the ec and GFS indicate a run of the mill storm for the area
on Saturday but like any day 8 forecast there could be big changes
from now until the day actually arrives.

Aviation 23 1107z.

At 11z, there was no marine inversion at klax.

Clear skies andVFR conds expected across the region thru the pd.

Klax and kbur... High confidence in the 12z TAF withVFR
conds thru the period. There is a 10-20% chance that east winds
reach 10 kt at klax between 12z-18z this morning.

Marine 23 305 am.

For the outer waters, high confidence in forecast. There is a 20%
chance of small craft advisory (sca) level wind gusts this morning.

Otherwise, SCA conds are not expected thru Tue morning. SCA level
south winds are expected Tue afternoon thru wed, except just a 30%
chance of SCA level conds in the southern outer waters zone (pzz676).

For the northern inner waters, SCA conds are not expected thru tue
morning. SCA level south winds are likely Tue afternoon thru wed.

For the sba channel and southern inner waters, SCA conds are not
expected thru wed.

Lox watches warnings advisories

zones 34>36-44>46-88-547. (see laxnpwlox).

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.
