Synopsis 25 1143 am.

A weak cold front will approach the northern areas by Tuesday.

A chance of showers may stall in the northern areas before moving
south by Wednesday. Dry weather is expected through the weekend
with a warming trend.

Short term (tdy-thu) 25 113 pm.

A trough over the eastern pacific appears to have two low pressure
centers, one a few hundred miles west of the wa coast and another
one about 500 miles farther west. Neither are moving too much as
the ridge ahead of it is blocking any significant eastward
propagation. Forward progress of the associated cold front has
also slowed as models have suggested and this will delay the
arrival of rain and clouds into our forecast area. Overnight
models do show some low level moisture developing beneath a fairly
low inversion so there will likely be some stratus developing
along the coast and pushing into the lower valleys early Tuesday.

Have kept in some small rain chances in for the far northwest
portion of slo county later tonight into Tuesday but it will
likely take well into Tuesday night before any threat of rain
reaches even sb county and not until Wednesday for ventura la
counties, if at all.

Rain amounts will be very light and probably not even reach .01"
for much of ventura la counties. In slo and NRN sb counties
generally a quarter inch or less but locally around a half inch
for the extreme northwest portion of slo county.

Temperatures will be cooler tomorrow as gradients trend onshore
but still a couple degrees above normal south of pt conception as
there still should be ample sunshine at least by afternoon if not
most of the day pending the overnight stratus development. Then
cooler again Wednesday with the additional cloud cover and chances
for light precip.

The front will finally pass through the area by Wednesday evening
followed by some gusty northwest winds that likely will require
some wind advisories Thu into Thu night, especially for southern
sb county and i5 corridor region. Temps Thursday similar or
slightly cooler than Wednesday.

Long term (fri-mon) 25 116 pm.

Pretty nice stretch of days coming up starting Friday as light to
moderate offshore flow sets up over the weekend and a strong ridge
develops over the west coast. Expecting coast valley temps to warm
up well into the 70s and 80s, especially south of pt conception.

Could be some locally gusty santa ana winds both Sat Sun but at
this time not expecting advisory level speeds. A little cooling
Monday as offshore flow weakens but still well above normal.

Aviation 25 1902z.

At 18z, around klax, there is a small weak marine inversion at 300
feet.

Low confidence in the arrival of coastal clouds, otherwise
moderate confidence in the 18z tafs.VFR conditions are expected
through much of the evening, except coastal sections up north may
start to see marine clouds late evening, and coastal TAF sites
south of point conception may see coastal clouds by the overnight
hours.

Klax... Low confidence in the arrival of marine clouds, otherwise
good confidence. Mainly ifr conditions expected with coastal
clouds. There is a 20 percent chance of east winds Tue morning.

Kbur... High confidence with 18z taf.VFR conditions are expected
throughout the period. 10% chance for ifr MVFR CIGS after 10z tue.

Marine 25 937 am.

For the outer waters, high confidence in current forecast. On
Thursday into Thursday night, there is a 60 percent chance of
small craft advisory (sca) level northwest winds across the
southern two zones of the outer waters, then across all of the
outer waters by Friday into next weekend.

For the inner waters north of point sal, moderate to high
confidence in current forecast through Wednesday as small craft
advisories (sca) levels through Wednesday. There is a 40% chance
for SCA level gusts on Thursday afternoon eve and up to 50% chance
for Friday afternoon eve. Confidence is a bit lower during the
weekend.

For the inner waters south of point conception, high confidence
in current forecast through Wednesday, with conditions below sca
levels. There is a 50 percent chance of SCA level winds across
the inner waters Thursday afternoon and evening. Confidence is
lower for SCA affecting the inner waters into this weekend. There
is a 40% chance for SCA for the inner santa barbara channel each
afternoon and evening fri-sat. Lower confidence for zone (pzz655)
with reaching SCA level gusts for the coastal waters off l.A.

County.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
