Synopsis 25 727 pm.

Tonight will be mostly clear ahead of a weak cold front
approaching the area. Cloud cover will increase on Tuesday and
Wednesday with cooler temperatures and a chance of rain.

Dry conditions are expected on Thursday with gusty winds. The dry
weather will continue through the weekend with warming
temperatures.

Short term (tdy-thu) 26 226 am.

A cold 534 dm upper low is about 300 nm to the west of seattle
(satellite show actually shows 3 lows all spinning in this general
area) 573 dm SW flow sits over SRN ca. A weak cold front bisects
the state with rain as far south as monterey county. Gradients are
weakly onshore and the marine layer is about 1200 feet deep. There
is enough clouds in the SW flow to make skies at least partly
cloudy and probably mostly cloudy over slo and sba counties. There
will also be some stratus across the central coast as well as la
county. The front will not move much but it may bring a light
shower or two to slo county ESP the northern section. Due to the
increased clouds slo and most of sba counties will have slightly
blo normal temps while the less cloudy vta and la counties will
have normal or slightly above normal MAX temps.

The front gathers a little more steam overnight and rain will
likely develop over most of slo and NW sba counties. Rain is
almost assured north of the city of slo. Rainfall amounts will be
under a quarter inch except the for extreme NW tip of slo county
where greater amounts are likely. Otherwise a coastal marine layer
stratus deck will develop under the mostly cloudy mid level
skies.

The upper low does not make much progress on Wednesday but an
impulse does move through the upper flow and this will spread a
chc of showers as far south as vta county. Slo and sba counties
will likely have scattered showers through the day. The increased
clouds along with increased onshore flow will bring 3 to 6 degrees
of cooling to the area and this will be the coolest day of the
next 7.

Rain amounts Wednesday 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.

On Thursday the upper low finally spins itself out and moves to
the east. There will be a slight chc of showers over the mtns but
otherwise look for dry conditions and clearing skies. MAX temps
will rise a couple degrees but will still be blo normal.

High pressure will build into the center of the state and will set
up moderate offshore north flow. There will be some cool air
advection as well. These two factors will combine and will likely
generate some low end advisory level gusts through the i-5
corridor.

Long term (fri-mon) 26 234 am.

Dry NW flow will set up on Friday. Skies will continue to clear
and hgts will rise to 576 dm. MAX temps will warm to normal or
even 1 or 2 degrees above normal.

Northerly offshore gradients will increase to about 7mb Friday
night. This strong N push will bring advisory level northerly
gusts to the mtns (except slo) and the sba south coast and
probably to the area 15 miles either side of the la vta county
line.

Weak ridging and diminishing offshore flow will combine to bring
three consecutive days of very nice weather with mostly clear
skies and warmer than normal temps. On Sunday and Monday there
will be a smattering of 80 degree temps and in general MAX temps
will be 4 to 8 degrees warmer than normal. There will be some
night through morning canyons but probably not advisory level.

Aviation 26 0638z.

At 06z at klax, there is a weak marine layer around 500 feet
deep. The top of the marine inversion was near 2300 feet with a
temperature around 17 degrees celsius.

North of point conception... Moderate confidence in TAF there is a
30 percent chc of light rain 20z-02z. There is 30 percent chc that
there will not be ifr cigs.

South of point conception... Moderate confidence in tafs with a 30
percent chc of MVFR CIGS 10z-17z. Better confidence in low clouds
arriving after 04z.

Klax... Moderate confidence in TAF with a 30 percent chance of
bkn015 conds 10z-17z. Any east winds should remain less than 7
knots.

Kbur... Good confidence in TAF with a 20 percent chance of bkn008
13z-16z.

Marine 26 1257 am.

For the outer waters, high confidence in current forecast. Today
through Wednesday, winds and seas will remain below small craft
advisory (sca) levels. For Thursday, there is a 60% chance of sca
level northwest winds and a 70% chance of SCA level northwest
winds Friday and Saturday.

confidence in current forecast. High confidence in winds and seas
remaining below SCA levels through Wednesday. For Thursday through
Saturday, there is a 50% chance of SCA level northwest winds each
afternoon and evening.

For the inner waters south of point conception, moderate to high
confidence in current forecast. High confidence in winds and seas
remaining below SCA levels through Wednesday. For Thursday through

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.
