920 am pdt Mon may 22 2017
Expect morning coastal stratus with fog and warm temperatures
early week as high pressure remains in control. A migrating low
pressure center will dramatically cool temperatures midweek and
extend morning stratus far inland.
Short term (tdy-wed)
a solid marine lyr has returned, mainly just for coastal areas,
with multiple vortices noted in the visible satellite imagery
spinning off the islands, including two oppositely rotating ones
in the sb channel. However, a clearing trend is already in full
progress and clouds should clear away from most areas by late
morning, though clouds could linger at some beaches north of la
county into the afternoon. The marine lyr along with a 2mb onshore
trend will push cooling into the valleys today, but another couple
degrees of warming expected for the far interior, including the
***from previous discussion***
for tonight into Tuesday, expect low clouds to push in across
coastal areas and possibly into some coastal valleys. High
confidence that the san gabriel valley will be affected by
stratus. Not much change on Tuesday as high temps should be around
the same, with a degree or two of warming across the antelope
valley. Locations away from the beaches will continue to remain
6-10 degrees above normal on Tuesday. Some gusty winds are
expected across the highway 14 corridor into the antelope valley.
Should remain just under wind advisory thresholds. Local gusts to
45 mph possible around lake palmdale and adjacent foothills.
For Tuesday night into Wednesday, the marine layer will deepen to
allow low clouds to reach all coastal valleys. There could be
locally dense fog across some valley locations. Onshore flow is
expected to reach around + 10 mb Wednesday, which is going to
bring windy conditions to the antelope valley and adjacent
foothills. Wind advisories might be needed for these areas. High
temps across valleys should remain in the mid 70s to lower 80s,
while the antelope valley will be in the lower to mid 90s. Much
cooler across coastal areas. All in all, high temps should be
around normal for this time of year.
One interesting note, both the GFS and nam-wrf are indicating a
very steep lapse rate, high CAPE values and lifted index readings
as low as 7 to 8 over the ventura county mtns, with slightly less
instability over the la county mtns. Looking at the latest model
soundings, there will be limited mid level moisture to tap into
Wednesday afternoon. For now, have added more cloud coverage over
the mountains. But there could be some elevated showers or even
isolated thunderstorm potential, especially over the ventura
county mountains. A couple concerns could be dry lightning and
chaotic downdraft winds if storms initiate then collapse. Will let
later shifts look closer at the moisture aspect. If mid level
moisture increases, then chance would be better for showers or
Long term (thu-sun)
both the GFS and ECMWF models continue to be in good agreement
with large scale features through the extended period. A more
significant cooling trend will occur on Thursday with high temps
across coast and valleys ranging from the mid 60s to the lower
70s, to around 80 in the antelope valley. Models also indicating
the marine layer to deepen quite a bit Friday morning. Added some
patchy drizzle in the san gabriel foothills to match up with the|
light rain that san diego NWS office added to areas to the east.
Still quite cool and clouds should linger into the afternoon
hours. Maybe a reverse clearing situation Friday afternoon. As for
winds, strongest southwesterly winds should occur Thursday/Friday
afternoons with the possibility of low-end advisory-level winds
across the mountains and deserts.
An upper ridge is progged to develop over the region Saturday and
Sunday which will start a modest warm up and bring some gusty
northerly winds to the usual wind prone areas including santa
barbara county mtns and adjacent south coast and the la/vtu county
mtns. Possibly needing wind advisories.
At 10z at klax the marine layer was 1100 feet deep. The top of
the marine inversion was at 2100 ft with a temperature of 24c.
Widespread low clouds and fog in all coastal areas this morning
with mostly ifr to lifr conditions, and local vlifr conds. Low
clouds and lifr to vlifr conds have also pushed into the santa
ynez valley. Low clouds have also pushed into portions of the
san gabriel valley. Expect clearing by mid morning in the valleys
and by late morning across the coastal plain. Some clouds may
linger at the beaches on the central coast through the afternoon.
The marine layer will deepen a bit tonight. Expect widespread low
clouds in coastal and most valley areas tonight. Conds will
generally be ifr, although should rise into the MVFR category
across coastal sections of l.A. County late at night.
Klax... Moderate confidence in the 12z taf. Expect ifr to lifr
conditions to improveVFR conds during late morning as CIGS scatter
out. There is a 20-30% chance that CIGS will linger through 21z.
Cigs should return this evening in the ifr category. There is a
20-30% chance that CIGS will hold off until at least 06z.
Kbur... High confidence in the 12z TAF thru this evening, withVFR
conds expected. There is a 10% chance of ifr CIGS between 13z and
16z this morning. Expect ifr CIGS to push into the airport late
tonight. There is a 20% chance that skies will remain clear tonight.
Marine 22/900 am
moderate confidence in the forecast. There is a 20-30% chance that
small craft advisories may needed across portions of the outer
waters during the afternoon and evening hours today through wed.
Areas of dense fog with visibilities 1 nm or less will affect most
all coastal waters this morning, and in northern areas late
tonight and Tue morning.
Hazard potential outlook (wed-sun)
advisory level southwest winds are possible Wednesday through
Friday across the mountains and deserts.

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.
