Area forecast discussion, Apr 19, 4:06 AM PDT, 5 hours 16 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
406 AM PDT Wed Apr 19 2017
.SYNOPSIS...
A weakening frontal boundary associated with an upper-level trough
of low pressure should exit the region through Tuesday. Breezy
winds will linger into Thursday as the low aloft moves east. The
air mass will warm to well above normal for late week and into the
weekend in breezy offshore flow. High pressure aloft will move
east early next week for cooler temperatures and increasing
clouds.
&&
.SHORT TERM...(TDY-FRI)
Yesterday's cold front was so anemic that it did not affect the
low level moisture fields in the least. As a result a 1400 foot
marine layer has formed and all manner of low clouds have fallen
out of it. The inversion is very weak so expect the low clouds to
mix out to mostly sunny skies by late morning or early afternoon.
There is some dense fog around the city of Santa Barbara as well
as the south coast where the marine layer is the most shallow. max
temps will warm as few degrees and will end up a couple of degrees
above normal.
A little trof ripple over the area tonight and at the same time
moderate north flow develops. The north flow will probably not
reach the LA coast or the San Gabriel Vly and some marine layer
stratus will likely develop. There will also be some gusty
northerly winds through the I-5 corridor and into the Santa
Clarita Vly. The SBA south coast will also see some gusty winds.
Some of these winds may require a low end advisory.
A ridge will quickly approach the state on Thursday. Skies will be
mostly sunny everywhere by mid morning. The rising, only weak
onshore flow to the east along with moderate offshore flow from
the north will allow for a nice warm up and max temps will rise 3
to 6 degrees and everywhere will see above normal temps.
The thermostat gets turned way up Friday. High pressure will
strengthen in the San Joaquin vly. Moderate offshore flow will
develop from the east and strong offshore flow will come from the
north. There is little in the way of upper or thermal support so
these gradients will only generate advisory level gusts along the
VTA/LA county line. The ridge axis will move overhead and hgts
climb to 585DM. Late April sunshine, high hgts, and the offshore
flow will all combine to add 6 to 9 degrees of warming to the area
temps. Max temps will be 12 to 18 degrees above normal and there
will be plenty of 90+ degree readings in the vlys.
.LONG TERM...(SAT-TUE)
On Saturday the ridge will be a little to the east of the area,
pushed away by an approaching trof. Offshore flow is weaker than
Friday but still offshore. The atmosphere will still be very warm.
Probably will be a classic day after the Santa Ana day with a
little cooling at the coasts due to the sea breeze but a little
warmer everywhere else due to the very warm airmass and continued
offshore flow.
The ridge moves a little more the east on Sunday and the upper low
scoots up to the north and east leaving flat dry westerly flow
over the area. The LAX-DAG gradient turn onshore while the
offshore BFL grad weakens and this will cause the temps to fall
down 8 to 12 degrees over the vlys. Most areas will still be a
couple of degrees above normal.
Monday will be a pretty non-described day dry northwest flow
overhead and a couple more degrees of cooling.
Just a little bit of cyclonic flow moves over the area Tuesday.
Onshore flow increase to the east and further weakens to the
north. This should bring some morning low clouds to the LA county
coast and perhaps the Central Coast as well. A few more degrees of
cooling will bring max temps a degree or two blo normal.

.AVIATION...19/1105Z...
At 1100Z, the marine inversion at KLAX was based at 1400 feet. The
top of the inversion was 2100 feet with a temperature of 14
degrees Celsius.
Overall, low confidence in all non-desert TAFs as CIGs/VSBYs will
continue to bounce between flight categories (ranging from LIFR to
VFR) through about 20Z. After 20Z, moderate to high confidence in
non-desert TAFs. For desert TAFs, high confidence in 12Z TAFs.
KLAX...low confidence in 12Z TAF through 20Z as CIGs and VSBYs
will bounce between IFR and MVFR levels. Through this afternoon
and evening, high confidence in VFR conditions. For tonight, low
confidence in forecast return of MVFR conditions.
KBUR...low confidence in 12Z TAF through about 18Z as CIGs and
VSBYs will bounce between IFR and MVFR levels. After 18Z, high
confidence in VFR conditions.
&&
.MARINE...19/130 AM...
For the Outer Waters, moderate confidence in current forecast.
Northwest winds are expected to increase to Small Craft Advisory
(SCA) levels this afternoon and will likely remain at SCA levels
through Sunday. There is a 50% chance of winds reaching Gale force
levels Thursday afternoon/night and again on Sunday.
For the Inner Waters, moderate confidence in current forecast. For
the waters north of Point Sal, moderate confidence in northwest
winds increasing to SCA levels each afternoon/evening from today
through Sunday. For the waters south of Point Conception, winds
are expected to remain below SCA levels through Thursday morning
(although there is a 20% of SCA level gusts this afternoon and
evening). For Thursday afternoon/night, winds will increase with a
good chance of SCA level winds across western sections. After a
lull on Friday, winds will possibly increase to SCA levels again
Saturday and Sunday.
