Whittier, CA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

821 pm pdt Fri jun 22 2018

Synopsis 22 346 pm.

Above normal temperatures are forecast for the inland, mountain and
deserts areas into Saturday. Next week the temperatures will be
around normal with a persistant overnight marine layer that will
spread inland in the onshore flow. Thursday, a low should arrive for
more clouds and a weekend cool down.

Short term (fri-mon) 22 821 pm.

Overall, high temps were a few degrees warmer today as expected.

Triple digit heat up to 105 degrees occurred at lancaster,
palmdale and paso robles this afternoon. Compare this to the high
of 58 at morro bay today. Not that unusual for this time of year.

The cooler marine layer influence helped keep coastal areas in the
60s and 70s with coastal valleys in the mid 80s to lower 90s. Earlier
today interior locations were actually experiencing light
offshore flow which allowed temps to climb higher today from
yesterday. However, not much change along coast and coastal
valleys as the marine layer stratus held tough along many coastal
areas S of point conception this afternoon.

Latest goes-16 vis satellite imagery indicated low clouds filling
into the ventura and l.A. Coastal areas this evening with a patch
of stratus around vandenberg afb near lompoc. Latest soundings
were showing the marine layer around 1600 ft near lax and around
1000 ft deep at santa maria. Expect a similar low cloud regime
for areas S of point conception as the marine layer will likely
reach 2000 ft again by Sat morning. For now, the central coast
remains mostly clear, but expecting low clouds to eventually
develop and move inland after midnight for most coastal areas.

Synoptically, the upper ridge that was over the region will start
to take on a more elongated NW to SE (positive tilt) look. An
upper trough will begin to dig south into the great basin on
Saturday. This will allow for h5 heights and boundary layer temps
to trend down some. Onshore flow is expected to strengthen
tomorrow as the NAM is advertising near +10 mb. Lately the NAM has
not been initializing well, but if today's strongest gradient
occurred this last hour at +6.3mb, expect at least a couple more
millibars stronger tomorrow. This should translate into some gusty
sw winds across the antelope valley and hwy 14 cooridor with the
usual localized sustained winds around 25 to 40 mph with gusts to
55 mph near lake palmdale tomorrow afternoon and evening. With
a strong inversion in place, expecting low clouds to linger along
some coastal areas tomorrow, but scour out of the valleys by mid
to late morning. Highs should be a few degrees cooler in most
areas tomorrow, especially across inland areas where highs should
reach around 100-102 in the antelope valley and paso robles. Most
other valleys will be in the 80s to around 90 in woodland hills.

***from previous discussion***
cooling trend will continue Sunday with temps dropping back down
to normal or even slightly below normal levels for the coastal
valleys, but still above normal well inland. Will probably also
see the marine layer depth increase to around 3000' as a weak
trough moves through the great basin. This should bring low clouds
in the southern salinas valley, santa clarita valley, and the
lower coastal slopes of the mountains.

There is some rebound in heights Monday but probably won't have a
huge impact. Perhaps a degree or two of warming inland and a
slight lowering of the marine layer but otherwise little change
from Sunday.

Long term (tue-fri) 22 144 pm.

Some warming expected Tue wed, mainly inland areas away from the
influence of the marine layer but otherwise pretty quiet weather
pattern. A trough will bring several degrees of cooling to inland
areas Thu Fri along with a deeper marine layer but highs still at
or slightly above normal levels. Low clouds will continue to hug
the beaches through the afternoon with limited afternoon clearing
there, especially south of pt conception, for the foreseeable
future.

Aviation 23 0032z.

At 2321z, around klax, the marine layer depth was around 1200
feet deep. The top of the marine inversion was around 4700 feet
with a temperature near 28 degrees celsius.

N of point conception... Moderate confidence withVFR conds through
08z then low confidence after that. Models not initiating well.

50% chance for lifr ifr CIGS to develop at ksmx after 11z. Could
occur a few hours earlier but confidence low that any CIGS will
develop. High confidence forVFR CIGS at kprb next 24 hours.

S of point conception... Moderate confidence with ifr to MVFR cigs
already across vtu and l.A counties and continuing through at
least 18z sat. 40% chance that MVFR CIGS could linger a few hours
longer. Moderate confidence for ifr CIGS becoming MVFR right
before CIGS scour out Sat mid to late morning.

Klax... Moderate confidence overall in the 00z taf. Low clouds
with ifr CIGS early, becoming MVFR CIGS are expected at the
airfield til around 20z sat. 30% chance for CIGS to scour out 2
hours after 00z taf.

Kbur... Moderate confidence overall in 00z taf. Low clouds with
ifr CIGS should move into the airfield by 07z tonight then clear
to MVFR vsbys around 17z sat. Otherwise,VFR conditions should
prevail for the most part. There is a 20% that CIGS will not
develop. Also, 30% chance that CIGS will linger an additional
hour from current taf.

Marine 22 818 pm.

For the outer waters, high confidence in the current forecast.

Small craft advisory (sca) level winds will continue through
tonight for pzz676, through Sat morning for pzz673, and through
sat afternoon for pzz670. Winds and seas are then expected to
remain below SCA levels Sat night through wed, but with a 20%
chance of SCA winds next Tue and wed.

For the inner waters, high confidence in the current forecast.

For the waters north of point sal, winds and seas will remain
below SCA levels through wed.

For the waters south of point conception, winds and seas will
remain below SCA levels through wed. However, for late Sat night
and sun, southeast winds are anticipated with a 70% chance of wind
gusts up to 15 kt.

Fire weather 22 327 pm.

Elevated to brief critical fire weather conditions are expected
to continue across interior areas through Saturday due to the
combination of hot temperatures, low humidities, and breezy
conditions. A 2000 foot marine layer kept coastal and valley
temperatures mild today, however a weak offshore wind influence
this morning across interior sections brought hot temperatures to
the mountains, deserts, and interior valleys above the marine
influence. These same areas have experienced widespread single
digit humidities today. The offshore wind influence from this
morning will continue to shift onshore through the afternoon,
with gusty northwest winds in the mountains tonight (mainly across
sba county mountains and i-5 corridor). In addition, the hot and
unstable conditions will also bring the potential for large plume
growth with any fire ignitions that develop across interior
sections this afternoon.

On Saturday, a stronger onshore wind influence will bring a slight
cooling to most areas, however there will still be some
triple digit readings and single digit humidities across warmest
interior locations. In addition, there will be stronger onshore winds in the
afternoon and evening, with gusts in the 30 to 40 mph range across
the mountains, interior valleys, and antelope valley, with isolated
gusts as high as 50 mph possible in the foothills of the antelope
valley. This increased wind threat combined with continued hot and dry
conditions will bring more elevated to brief critical fire weather
conditions across interior sections on Saturday, especially the highway
14 corridor from santa clarita valley into the antelope valley.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect until 3 pm pdt Saturday for
zone 670. (see laxmwwlox).

Small craft advisory in effect until 9 am pdt Saturday for
zone 673. (see laxmwwlox).

Small craft advisory in effect until 3 am pdt Saturday for
zone 676. (see laxmwwlox).

Hazard potential outlook (mon-fri)
No significant hazards expected.
