Aviation discussion update...

Synopsis 23 719 am.

Mostly clear skies will prevail today and temperatures will warm
slightly but remain below normal. The dry weather will persist
through the weekend and into early next week and temperatures will
warm up to near normal. There is another chance of light rain by
mid-week over northern areas.

Short term (tdy-mon) 23 903 am.

Sunny skies covered the forecast area this morning. Some hi clouds
over the E pac should move into the area by afternoon, but mostly
sunny skies will still prevail through late today. Light offshore
flow this morning will turn weakly onshore this afternoon.

Temperatures today should turn slightly warmer than yesterday but
remain several degrees below normal for all areas. Highs for much of
the coast and vlys should reach only into the upper 50s to low 60s.

Weak, flat upper level ridging is expected to move over SRN ca
today. A mainly zonal flow aloft with little change in 500 mb
heights should prevail tonight through mon. 500 mb heights should
remain in the 566 to 568 dm range thru the period.

Generally benign weather is expected over southwestern ca tonight
thru mon. Fair skies will prevail thru the period with some hi
clouds expected to drift overhead at times. There is also the
possibility that patchy marine layer clouds may begin to develop
along the central coast and l.A. County coast later Sun night into
mon morning. Some breezy offshore flow is again expected for the
wind-prone areas tonight into Sun morning, but overall winds will be
weak and variable across the region thru mon.

Temperatures are forecast to warm a few more degrees Sun and mon
thanks to gradually increasing 1000-500 mb thicknesses and some
warming in the boundary layer. Highs in the warmest vlys and coastal
areas are expected to be in the lower to mid 60s on sun, which are
still a few degrees below normal. Expected highs in the mid 60s to
near 70 for these areas on Mon are near normal for this time of
year.

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 1805z.

around 500 feet. The temperature at the top of the inversion was

prevail throughout the forecast period.

Marine 23 852 am.

For the outer waters... Conditions will remain below advisory
levels through Tuesday morning. Winds will increase to small craft
advisory level in the northern and central outer waters Tuesday
afternoon and continue through Wednesday. There is a thirty
percent chance of SCA level winds in the southern outer waters

levels through Wednesday.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
