Synopsis
Strong winds will continue tonight then begin to diminish by mid
Tuesday morning. Temperatures will increase through Wednesday. An
approaching low pressure center will cool temperatures by
Thursday.

Short term (tdy-wed)
strong northwest flow has developed behind a trough that passed
through the area earlier this morning. Good subsisidence is also
helping to drive higher winds speeds from aloft down to lower
elevations. Advisory and warning level north to northwest winds
are expected across many areas through tonight before the shift to
santa ana northeast winds takes place Tuesday morning. The
northeast winds won't be as strong in most areas as the northwest
winds were, but cross sections of model data through the typical
favored santa ana wind areas shows winds near 40kt down to around
850 mb. So while this won't likely be a warning level santa ana
event it should at least keep winds in the advisory category
through the morning hours and possibly into early afternoon. So
the 9am expiration of some of the la/ventura county advisories
have been extended until 2 pm to account for the santa ana winds.

With the trough exiting east and good downslope flow taking place
with the santa ana winds most areas, especially west and south of
the mountains will see a sizable jump in temps Tuesday and again
Wednesday. Gradients are actually peaking Wednesday but upper
support wanes as the ridge axis moves overhead. So still some
gusty winds but mostly below advisory levels. Highs will warm up
well into the 80s in the valleys and some lower 90s for the
warmest areas by Wednesday. 70s to lower 80s for coastal zones.

Another trough that will eventually become our next inside slider
will hit NRN california early thu. This will quickly reverse
gradients and cool temps several degrees Thu afternoon. Northern
areas may see a few clouds from it Thu afternoon but no precip.

May have to watch for some more grapevine area showers Thu night
but at present models aren't showing much moisture lingering
behind it so will keep forecast dry. But it will initiate another
round of gusty north to northwest winds Thu into Thu night in
many of the same areas as this morning and likely with similar
speeds if it follows the currently expected trajectory.

Long term (thu-sun)
a similar pattern shaping up for the end of the week as we're
seeing in the first half of the week. Strong northwest flow thu
into early Fri behind the trough with cooling temps, then
shifting to northeast Friday into Saturday for a quick warmup back
into the 80s for the valleys and 70s for coastal zones. Then
cooling again Sunday with the next trough which again appears to
be taking an inside track. Though here the GFS and ECMWF part ways
quite a bit with the ec showing a much faster and weaker trough
passage with virtually no gusty northwest flow behind it. So
somewhat lower confidence as we get later into the weekend but
given the pattern it seems prudent to hold onto the inside sliders
for the time being.

Aviation 27/1800z.

At 1718z at klax... There was no marine inversion.

Low level wind shear is possible just about anywhere today due to
very strong winds and turbulence. All TAF locations are expected
to haveVFR conditions through Tuesday.

Klax... Good confidence in the 18z taf. There is a 30 percent
chance of north cross winds near 10 knots between 03-09z.

Otherwise,VFR conditions and possible low level wind shear. East
winds, if any, will stay below 7 knots.

Kbur... Good confidence in the 18z taf.VFR conditions will
prevail with possible low level wind shear.

Marine 27/200 pm.

Lots of changes on the marine package. The gales are still
expected this afternoon, but they are off to a slow start.

Changed the ending time of the gales for the outer waters to 11z
and inner waters to 05z as it does not look like the gale winds
will stick around any longer than that.

Changed the wave heights in the grids to better match with
surrounding offices and the latest coastal/marine guidance. Still
expecting some rather steep and choppy waves this afternoon into
this evening during the strongest period of winds.

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.
