Synopsis
Gusty northwest to north winds will likely continue through the
work week for portions of southwest california with weak to
moderate offshore winds possible by this weekend. A gradual
warming trend is expected for most areas through this weekend.

Short term (tdy-thu)
another windy day across much of the area, clearly the theme of
the week. Advisory level winds surfaced in the sfv as well as the
eastern ventura valleys and sm mtns so added them to the wind
advisory. Based on local hi resolution models the winds in these
areas should start to diminish by mid to late afternoon but still
breezy at times through the night.

Highs temps today should be slightly warmer as the ridge over the
eastern pacific starts to push into the state and onshore
gradients weaken. Already seeing decent positive 24 trends this
morning, especially coast/valleys so expect this to continue today
and even more so Wednesday with better ridging aloft and weak
offshore flow.

***from previous discussion***
an upper low was located in wyoming with a trough extending
southwestward into the great basin. There was broad cyclonic
northwesterly flow across the forecast areas. MAX temps
should edge upward a few degrees today as heights and thicknesses
rise slightly. Expect areas of low clouds on northern slopes and
across interior sections of slo and sba county, and possibly
across the santa ynez valley and portions of the central coast
tonight/wed morning, with mostly clear skies elsewhere. Winds
should decrease below advisory levels on the central coast this
evening, across the antelope valley late tonight, and across
southern sba county and the santa clarita valley Wed morning.

However good n-s grads and decent NW winds aloft should make
for windy conditions again Wed afternoon or evening into thu
morning. Wind advisories will likely be needed again on the
central coast Wed afternoon, and southern sba county and
the santa clarita valley Wed evening into Thu morning. Rising
heights and thicknesses should lead to several degrees of warming
in most areas on wed.

An upper low will drop into montana Wed night and thu.

This will cause northwesterly flow aloft to increase across the
region thu, and any lull in the winds Thu morning should be
brief. Additional wind advisories will likely be needed thu.

Max temps should be down a few degrees in most areas thu.

There may be a bit more in the way of stratus Wed night/thu
morning north of pt conception, and plenty of clouds are
expected on northern slopes with a slight chance of showers there
late Wed night into Thu morning

Long term (fri-mon)
the upper low will drop into utah on fri, with fairly strong nw
flow aloft over the forecast area and continued steep n-s
gradients. Gusty NW to N winds will continue to affect similar
portions of the region on fri. Do not expect too much in the way
of stratus Thu night into Fri morning, especially south of pt
conception. MAX temps on Fri should be up a few degrees in most
areas, mainly west of the mountains.

Height and thicknesses will rise over the weekend as an upper
ridge amplifies along the west coast. Low level flow will
turn more northeasterly by sat, and though low level flow will
weaken on Sunday, it will remain offshore, at least in the
morning. Expect MAX temps to jump Sat on, especially west of the
mountains, with highs likely in the lower 90s in the warmer valley
locations. There may be a few degrees of cooling across the
coastal plain on Sunday, especially near the coast, but it will be
very warm elsewhere. As the upper high begins to break down on
Monday, and flow turns onshore, expect cooling in coastal and
valley areas, with little change in temps in the mtns and deserts.

Aviation 25/1200z...

at 1130z, there was no marine layer inversion to speak of around
klax early this morning.

Overall,VFR conditions are expected for most areas away from the
interior locations including the northern mountain slopes. There
will be MVFR patchy CIGS in the vicinity of ksbp and ksmx through
17z this morning as well as kprb. Northerly winds should keep MVFR
cigs away from la/vtu county coastal and valley location over the
next 24 hours. There is a 50% chance that MVFR CIGS could develop
around the central coast and interior areas later today through
tonight. Bands of acsl were streaming across the leeward side of
the tehachapi mtns and could continue through this morning. There
will be some uddf across the mountains and llws is expected
around ksba later this afternoon, and kvny through today.

Klax... Moderate confidence in 12z taf. There is a 20% chance of
MVFR CIGS 10z-15z Wed morning. High confidence inVFR conditions
tonight.

Kbur... High confidence in 12z taf. There is a 30% chance of
llws/turbulence through 18z.

Marine 25/900 am.

For the outer waters, high confidence in current forecast. Strong
northwest winds are anticipated to continue through the week.

Currently, a gale warning is in effect through late Wednesday
night. There is a 70% chance that gale force winds will continue
through Friday.

For the inner waters, moderate confidence in current forecast. A
gale warning has been issued once again valid for this afternoon
for the inner waters south of point conception, mainly affecting
the western portions. Otherwise, strong small craft advisory (sca)
level winds are expected each afternoon/evening in zone 645 through
Friday with a 30% chance of gale force wind gusts developing. Due
to strong winds throughout the waters, seas will be very choppy
this week, making for hazardous boating conditions through the
week.

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.
