Synopsis 16 746 pm.

Strong and gusty winds will affect southern santa barbara county
and the interstate 5 corridor tonight. Temperatures will gradually
cool to below normal in many location by Sunday then will warm
again next week. Overnight and morning low clouds will be
widespread in coastal and adjacent valleys by midweek.

Short term (tue-fri) 16 801 pm.

***update***
strong northwest to north winds are affecting southern santa
barbara county this evening, mainly near and west of refugio, and
are expected to continue through late tonight. After 4 am
Wednesday, the winds will diminish some, with peak gusts near 30
mph through around 8 am. After that winds will diminish more
significantly over sba county. Meanwhile the moderate to strong nw
winds over the outer coastal waters have helped to spin up a
catalina eddy along the southern l.A. Coast. This combined with a
weak trough over the west coast will push a low cloud deck inland
over the l.A. And ventura coastal basins, the san gabriel valley,
and possibly the san fernando valley. Portions of the ventura
valleys closest to the coast will also see low clouds and patchy
fog. Along the central coast, low clouds are expected to move
inland overnight and into the santa ynez valley.

The coastal trough and increasing onshore flow will cause all
areas to trend cooler through the next few days. In addition,
gusty onshore southwest winds will affect interior passes and
canyons, strongest through the highway 14 corridor and the
antelope valley. Gusts to 40 mph or stronger will be likely in
this area each afternoon to overnight period through the next few
days, and possibly through the weekend.

Low clouds will push well inland starting tomorrow night, across
all of the valleys toward the western mountain slopes. This
pattern is likely to continue through late in the week, into
early this weekend. Temperatures are expected to fall to near
normal tomorrow and slightly below normal Thu fri.

Long term (sat-tue) 16 144 pm.

The west coast trough starts to weaken late Friday allowing the
high pressure ridge over the southern half of the country to
expand west again over the weekend into early next week. Daytime
highs will begin a slow climb Saturday then really kick in Mon tue
as both the GFS and ECMWF show a strong upper ridge developing
near the four corners as well as onshore flow weakening. Mos
guidance numbers seem low given the upper and surface patterns
but the agreement in the models and their ensembles on the
strength and position of the ridge gives more confidence that
we're heading into another warmup next week. While current
forecast temps Tuesday are about 5 degrees above MOS guidance
numbers they are at the upper end of the ensemble range and still
might be too low if the pattern evolves as models are showing
today.

This pattern will open the door for monsoon moisture to move up
from mexico but as of now no big sources have been identified by
the models and for the most part our area remains pretty dry aloft
while southeast california likely will see an increase in
afternoon convection.

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.
