Synopsis 23 240 am.

Many areas will have above normal temperatures today. There is a
slight chance of afternoon thunderstorms over the ventura and los
angeles county mountains and deserts each afternoon today through
Thursday. Morning low clouds will diminish through Wednesday and
then slowly increase through the weekend.

Short term (tdy-thu) 23 309 am.

A very tricky weather situation this morning. A shallow marine
700 foot marine layer has generated low clouds from oxnard up
around pt conception and across the central coast. The onshore
flow is rather weak so the low clouds are not making much inland
penetration. Some low clouds may develop across the la county
beaches but they will not be widespread. Quite a bit of mid and
high clouds embedded in the SE flow around a four corners high are
streaming overhead and skies over la vta county will be partly to
mostly cloudy today. The radars are showing quite a few returns
so there is likely some virga falling from some of the mid level
clouds. There is a slight chc that the la vta mtns are high enough
to allow some light rain showers. Additional moisture and
instability will rotate into area this afternoon and will be
enough to produce a slight chc of showers and tstms over the
la vta mtns and portions of the antelope vlys. Above normal 592 dm
500 mb hgts and weakening onshore flow will bring very warm temps
to the forecast area today. The vlys should see the biggest jump
in temps as there will be much less marine influence. The
interior will not warm much as hgts are not too different from
ydy. There will be enough warming to create low end heat advisory
conditions on the san fernando and cuyama vlys as well as the slo
county mtns this afternoon and evening. The fly in the ointment is
the mid level clouds which could limit the afternoon warming.

There should be less mid and high level clouds on Wednesday. The
onshore flow weakens as well and in fact is near neutral at dawn.

This will greatly eliminate the morning marine layer clouds. Hgts
will remain the same but there will be less onshore flow and more
sunshine so Wednesday will be the warmest day of the next 7 more
vly and interior areas will likely need heat advisories for the
afternoon and evening. There will be less moisture and instability
but there will still be enough to warrant a slight chc of tstms
across the northern vta mtns and the eastern la mtns.

Thursday will be very similar to Wednesday except that there will
be stronger onshore flow both to the north and the east. This will
bring cooling to the coasts and vlys (to a lesser extant). There
will likely be just enough cooling to keep the temps below
advisory levels. The SE flow around the 4 corners high will again
provide just enough moisture to bring a slight chc of TSTM to the
northern vta mtns and the eastern la mtns.

Long term (fri-mon) 23 316 am.

The ec and GFS agree that the upper high will drift to the west on
Friday and then settle over california for the weekend and early
next week. 596 or even 597 dm hgts are possible Saturday and
Sunday.

The westward shift of the upper high will cut off the monsoon flow
and eliminate the threat of mtn convection.

The deserts will warm further to near 105 degree over the weekend
or 5 to 8 degrees above normal.

There will be increasing onshore flow both to the north and east.

This will bring the marine layer back to the coasts but the hgts
are too high to allow it into the vlys. Still there will be
earlier and stronger seabreezes and this will temper any warming
caused by the increase in hgts.

There will be a little cooling on Monday but not much.

Aviation 23 1134z.

At 0500z at klax, the marine layer was around 700 feet deep. The
top of the inversion was near 1700 feet with a temperature of 26
c.

Moderate confidence in coastal tafs. Kcma ksmo klax and klgb have
a 30 percent chc of ifr CIGS 13z-16z. Ksmx ksbp ksba koxr could
clear two hour later than fcst.

Good confidence in inland tafs.

Kpmd and kwjf there is a slight chance of a thunderstorm with
gusty and erratic winds 22z-02z.

Klax... Moderate confidence in taf. There is a 30 percent chc of
ifr conds 13z-16z. Good confidence of no east wind component.

Kbur... High confidence inVFR taf.

Marine 23 228 am.

For the outer waters... Winds will increase this morning across the
northern outer water zone (pzz670) then expand south to pzz673
late this morning to around point conception and areas west. The
sca that was issued for the southern waters (pzz676) has been cancelled
as winds are not expected to be as strong NW of san nicolas island
this afternoon and evening. SCA winds and steep seas should continue
across the outer waters through at least late Wednesday night or
early Thursday morning.

For the nearshore waters between point piedras blancas to point
sal... Winds should remain below SCA levels through at least
Wednesday evening. However, there is a 40% chance that for sca
level gusts, mainly across the western portions each afternoon and
evening today and Wednesday.

For the inner waters south of point conception, conditions should
remain below SCA levels through at least Thursday. However, there
is a 30 percent chance of SCA level winds in the western santa
barbara channel each afternoon and evening Tuesday and Wednesday.

Beaches 22 515 pm.

A marginally long period southerly swell could bring the
possibility of strong rip currents to area beaches Wednesday and
Thursday. A beach hazards statement might be needed for the
middle portion of the week.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
