Synopsis 14 804 pm.

An upper level high pressure system over the area will allow for
temperatures to warm across the region through Wednesday. Night
through morning low clouds will return to most coastal areas
through most of the week. Later this week, a low pressure trough
will bring temperatures down again and gusty northerly could
develop going into the weekend.

Short term (tdy-thu) 15 309 am.

The marine layer is about 1000 feet deep. There is only weak
onshore flow to the east and there is weak offshore flow from the
north. There are 2 to 3 mb offshore trends both to the south and
west. The offshore trends are keeping the skies clear south of pt
conception. Low clouds brought about by the NW flow across the
waters, cover most of the central coast and portions of the santa
ynez vly. Some low clouds will also work their way into the paso
robles area from the north. A ridge will move into the state on
the heels of ydy's trof. Hgts will rise to 582 dm and this
increase along with the weak offshore flow will allow most
locations to jump 6 to 12 degrees up from ydy's MAX temps.

Not too much marine layer stratus tonight. The NW flow near the
central coast will produce some stratus there and a weak eddy may
bring some low clouds up into the southern portion of the la
county coast.

Not much change for Wednesday. Hgts and pressure grads are
similar. Except for the central coast where there will be onshore
trends and a few degrees of cooling
a large broad trof will sweep across the west coast Wednesday
night and Thursday. It is not moist enough for rain but it will
bring enough mid and high level clouds to make for partly cloudy
skies. Onshore flow will increase to the east but there will be
pretty good offshore flow to the south. The central coast should
see some low clouds develop as the lift from the trof approaches
but the northerly offshore flow will keep the low clouds away from
most areas south of pt conception save for the la south coast. The
north push will also create a sundowner for southern sba county
and the i-5 corridor. Wind gusts speeds will be near advisory
levels.

The lower hgts and increasing onshore flow to the east will bring
about a cool down to the entire area. The areas where there was
offshore flow Wednesday will see double digit cooling as will the
interior sections as hgts fall to 573 dm. Most areas will be 3 to
6 degrees blo normal.

Long term (fri-mon) 15 324 am.

Fast moving dry NW flow will be over the state through Sunday and
both the ec and GFS agree that an east pac high will push in from
the west on Monday.

There will be northerly offshore flow through the period. It will
increase each day. The lax-bfl grad will peak Sunday near 7 mb and
the sba-bfl grad will peak near 6 mb also on Sunday. These
gradients will likely produce advisory level winds across the sba
south coast and the i-5 corridor each night with isolated warning
level gusts on Sunday.

The offshore flow will mostly eliminate the marine layer and
stratus potential but Friday morning there could be some lingering
low clouds across the la south coast.

Max temps will rise all three days. The biggest bump up will occur
on Sunday when MAX temps will rise to 3 to 6 degree above normal.

The sfc flow shifts to a more typical santa ana direction on
Monday as the ridge pushes in. The offshore grads are a little
weaker than previously forecast and there does not look like there
will be much in the way of upper or thermal support so it does not
look like it will turn into a high end event. What it will do is
really warm things up. Almost all MAX temps across the coasts and
vlys will be in the 80s with a smattering of lower 90s in the
vlys. In fact all of next week looks to be on the warm side.

Aviation 15 0831z.

At 0600z at klax, the marine layer was 1000 ft deep. The top of
the inversion was near 3500 ft with a temperature of 16 c.

Good confidence in all tafs except klax and klgb where where there
is a 30 percent chc of bkn008 12z-15z and kprb where there is a 40
percent chc of ovc002 12z-16z.

Klax... Moderate confidence in taf. There is a 30 percent chc of
bkn008 12z-15z. Good confidence that any east wind component
will be under 5 kt.

Kbur... .High confidence in cavu taf.

Marine 15 311 am.

High confidence that winds and seas will remain below small craft
advisory (sca) criteria today over all of the coastal waters.

For the outer waters along the central coast and southward toward
san nicolas island, NW winds are expected to increase to sca
levels on Wednesday afternoon and continue through at least
Saturday. For the waters closer to shore, winds will likely reach
sca level on Thursday afternoon. Moderate to high confidence in
winds exceeding gale force starting Thursday night, mainly over
the waters farther from shore.

For the inner waters south of point conception, winds will remain
below SCA levels through early Thursday. Moderate to high
confidence in winds increasing to SCA level Thursday afternoon over
the western half of the santa barbara channel, possibly reaching
gale force on Friday and Saturday.

A long-period, large NW swell is expected to move into the waters
on Thursday and will likely persist through the weekend.

Lox watches warnings advisories
Ca... None.

Pz... None.

Hazard potential outlook (thu-mon)
Gusty sundowner winds are expected for southern santa barbara
county Thursday through Sunday. Gusty northerly winds also
possible for the interstate 5 corridor region Friday through
Sunday.

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.
