Synopsis 22 810 pm.

Gusty offshore winds will continue through Wednesday across many
mountain and valley areas and will be strongest during the morning
hours. Temperatures will gradually warm through the week to above
normal as conditions remain dry and sunny.

Short term (tdy-fri) 23 320 am.

Clear skies and dry air have allowed for good cooling in wind
sheltered areas. Ojai residents will wake up to freezing or near
freezing conditions. Currently there is 3 to 4 mb of offshore
flow and it is forecast to increase by another mb or so by 15z.

This will bring advisory level gusts to most of vta and la county
through the late morning before diminishing. The state is under
the anti cyclonic flow of an east pacific ridge. Hgts are near 582
dm. There is no cold air advection today so temps will rise
nicely and will end of 2 to 4 degrees above normal.

The air mass will continue warm tonight and although some vly
locations will have blo normal min temps there will be much less
near freezing conditions.

Thursday will be a very nice day with offshore flow bringing sub
advisory level gusts to the canyons in the morning. The warm
airmass, weak offshore flow and cloud free skies will keep max
temps running 2 to 4 degrees above normal.

A little inside slider moves over the area Thursday night and will
increase the east to west offshore flow Friday morning. The
offshore flow from kdag is forecast to peak at 7mb which is strong
enough to bring advisory level NE winds to the east and northeast
oriented passes and canyons as well as the areas below them. Hgts
are a little lower and this will knock a degree or two off of the
max temps.

Long term (sat-tue) 23 320 am.

The ec and GFS are in good agreement through the period. On
Saturday the ridge will begin to move over the state and by Sunday
the ridge will be centered over the state. On Monday the ridge is
knocked down by a trof moving out from the great basin. This trof
continues to move down through the state on Tuesday. The GFS which
had been advertising continued ridging on Mon and Tue switched and
now is much like the ec.

The offshore flow is similar to Friday morning and there will
probably be some low end advisory level gusts on Saturday morning.

Max temps will continue to run 2 to 4 degrees above normal under
sunny skies.

Sunday will be the warmest day of the next 7 as the ridge moves
directly over the state. The offshore flow will weaken so while
there will be some canyon winds they will not reach advisory
levels. MAX temps will end up 4 to 8 degrees above normal.

Cooler Monday as hgts fall and offshore flow relaxes due to the
approaching trof. Still MAX temps will be 2 to 5 degrees above
normal.

Tuesday looks like it could be a very interesting day as both the
ec and GFS build in a large sfc high into the great basin. Both
the ec and the GFS show almost 10 mb of offshore flow from kdag.

If this verifies dangerous wind gusts will be common across much
of la and vta counties.

Aviation 23 1149z.

At 11z, there was no marine layer at klax.

Vfr conditions are expected thru the period. There is a chance of
moderate low-level wind shear and turbulence at terminals south
of point conception thru 18z.

Marine 23 345 am.

Winds and seas will likely remain below small craft advisory
levels thru sun. There is a 30% chance of SCA level winds tonight
thru Thu evening, mainly across the northern two zones (pzz670-673).

For the inner waters north of point sal, mostly high confidence
in the forecast. Winds and seas are expected to remain below sca
levels through sun.

For the inner waters south of point conception, moderate
confidence in current forecast. SCA level winds are likely from
pt. Mugu to santa monica this morning. There is a 30% chance of
sca level winds across eastern portions of the sba channel near
short from ventura to pt mugu this morning.

There is a 20% chance of SCA level NE winds late Thu night fri
morning across eastern portions of the sba channel and the southern
inner waters from pt mugu to santa monica, and a 40% chance of
sca level winds in these areas late Fri night Sat morning.
