area forecast discussion... Updated
national weather service los angeles/oxnard ca
1118 pm pdt Mon may 22 2017

Synopsis
Very warm conditions are expected to continue through Tuesday.

A weak low pressure center will approach the southwest california
coast on Wednesday... Dramatically cooling temperatures through
Friday. Overnight to morning low clouds and fog will extend
further inland each day through late in the week. A ridge of high
pressure will bring a warming trend to the area Saturday through
early next week.

Short term (mon-thu)
the marine inversion at klax was near 800 ft deep early this evening
and was a rather strong inversion, with the base at 55 deg, and the
top at 80 deg around 2000 ft. At kvbg, the 00z sounding showed an
inversion depth of 1300 ft and also strong with a base temp of 50
degrees, and the inversion top temp at 75 deg at 3200 ft. Low clouds
and fog were noted along many coastal areas early this evening
except for the sba county S coast. Weak onshore gradients will help
the low clouds to expand over the coastal waters and along all
coastal areas thru tonight, with patchy low clouds and fog possible
into some of the adjacent vlys. Patchy dense fog will also be
possible later tonight with the shallow and strong marine inversion.

Otherwise, mostly clear skies will prevail across the forecast area
overnight.

Upper ridging over SRN ca will persist over the region thru tue.

Flat upper ridging can be expected over the region Tue night and
wed, followed by an upper level trof moving into the area from
the NW Wed night and thu.

The marine layer pattern will continue over the forecast area tue
thru thu. The marine inversion will deepen thru the period, with low
clouds and fog moving further inland each night. By Wed night, it
looks like the marine layer will deepen to at least 3500 feet with
the low clouds moving well inland to the lower coastal slopes and
into much of the slo county interior vlys. Patchy drizzle cannot be
ruled out later Wed night and Thu morning as well, especially from
the coast to coastal slopes of vtu/l.A. Counties. The deep moist
layer clouds on Thu may be persistent thru the day for many areas as
well. All this will be in response to the upper level trof moving in
wed night and Thu and increased onshore flow.

There may also be a few clouds over the mtns Wed afternoon,
otherwise mostly clear skies can be expected Tue thru wed, with
mostly clear skies Thu mainly for interior portions of the forecast
area.

Gusty S to W winds can be expected during the afternoon and evening
hours for the foothills, mtns and deserts during the period. The
strongest winds are expected on Thu with some gusts possibly
approaching advisory levels at times especially in the mtns and
deserts.

Temps will be on a cooling trend Tue thru thu, with highs still
several degrees above normal away from the coast on tue, then
cooling to near normal for the most part on wed, and several degrees
below normal for thu. Afternoon temps for the warmest vlys will peak
in the upper 80s to lower 90s on tue, except upper 90s in the
antelope vly, then cool Wed to the upper 70s to low 80s except upper
80s to around 90 in the antelope vly, and upper 60s to around 70 on
thu except around 80 in the antelope vly.

***from previous discussion***

Long term (fri-mon)
one more cool, slow clearing, strong onshore flow day Friday
before the low and long wave trough shift east Saturday and a
ridge develops through early next week. High temps still likely
a few degrees below normal Saturday but warming to normal or
slightly above Sunday and then warmer still Monday. Current
forecast for Monday if anything, is a tad on the cool side if
current model projections hold.

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.
