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.

Synopsis 21 910 pm.

Above normal temperatures and breezy winds 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 with the onshore flow.

Next Thursday, a low may arrive for more clouds and a weekend
cool down.

Short term (thu-sun) 21 852 pm.

Low clouds were stubborn to scour out along the coast due to the
strong inversion in place with a strong onshore gradient.

Although h5 heights were 594dm overhead, the marine layer around
2000 ft this morning to go along with the sharp onshore gradient,
this kept high temps comfortable along coastal areas, and not
quite as hot as forecast for the valleys, yet still quite warm.

However, the marine layer influence was not a factor across the
lower mountain elevations and interior areas where triple digit
heat was occurring. Palmdale and lancaster reached 105 and 104
respectively, while paso robles was 100 degrees. While woodland
hills reached 91. Most of the l.A. And ventura county valleys were
up to 4 degrees cooler due to the deep marine layer influence.

As far as this evening, latest goes-16 vis satellite indicated low
clouds already into l.A. And ventura coastal areas as well and to
a lesser extent, the central coast. Latest sounding around lax
showed the marine layer around 1500 ft. Expecting the marine layer
depth to be a bit more shallow compared to today, and with the
onshore gradients expected to be trending 2 mb weaker, with weak
offshore flow expected across the interior areas in the morning,
boundary layer temps for Friday are expected to increase. Friday
will be the warmest over the next few days. Overall, highs will be
1 to 3 degrees warmer along the coast and up to 5 degrees warmer
in the valleys and lower mountain elevations and even a few
degrees hotter in the antelope valley tomorrow. If planning on
hiking and doing any outdoor activities in the valleys, mountains
and deserts, stay hydrated and exercise early tomorrow, or in the
evening hours. Highs will reach 108 across the antelope valley and
105 at paso robles. There should be enough marine layer influence
to keep the san fernando and san gabriel valleys in the upper 80s
to mid 90s near woodland hills. We do not issue heat advisories
for the antelope valley, only excessive heat warnings, and will
not meet the thresholds for that.

For Saturday, an upper low begins to push south into the
intermountain region around idaho and a broad trough associated
with the low will deepen slightly over southern california keeping
the upper ridge over the eastern pac. This along with stronger
onshore flow will cause high temps to trend lower 2 to 8 degrees,
with best cooling expected away from the coastal areas.

***from previous discussion***
then as mentioned turning cooler
over the weekend, especially Sunday as onshore flow (both
south north and west east) really increase and keep that cooler
maritime air in place. By then daytime highs will be near to
slightly below normal in most areas. With the onshore push over
the weekend look for increasing afternoon west southwest winds in
the antelope valley that may approach advisory levels in the
some areas, especially Sunday. Overall a pretty quiet pattern.

Long term (mon-thu) 21 122 pm.

Fairly minimal day to day changes next week once the big cool down
occurs over the weekend. Low clouds will continue to push into the
valleys each night and then clear to within a few miles of the
beach each afternoon. The ECMWF continues to be more bullish with
a trough for the latter part of next week, going with much more
digging and colder air aloft coming in Thu Fri than either the gfs
or gem solutions. For now will keep a mostly persistence forecast
going through Thu and wait and see about that next trough.

Aviation 22 0601z.

At 0530z, the marine layer around klax was around 1400 ft deep.

The top of the inversion was around 4000 ft with a temp of 27c.

Widespread low clouds in coastal areas will spread into most
valley areas overnight. Conds will be mostly ifr to lifr except
locally MVFR across coastal sections of l.A. County. Expect cigs
to rise into the MVFR category in most areas around daybreak.

Skies should clear by mid morning in the valleys, and by noon
across the coastal plain. Clouds may linger into the afternoon at
the beaches.

Klax... Moderate confidence in the 06z taf. There is a 30% chance
that ifr conds may persist through 15z. There is a 20% chance that
cigs will linger through 22z. Not expecting any SE wind issues
over 6 kt overnight.

Kbur... Moderate confidence in the 06z taf. There is a 30% chance
that CIGS will not arrive until 12z.

Marine 21 913 am.

For the outer waters, high confidence in the forecast, with winds
increasing to SCA levels this morning, and continuing thru late
fri night or Sat morning, then winds will diminish. Winds may drop
below SCA levels briefly at times.

For the inner waters, north of point sal, good confidence in sca
level winds mainly during the afternoon evening hours thru fri.

For the inner waters south of point conception, winds and seas
are expected to remain below SCA levels thru sun. However, there
is a 30% chance of SCA level winds across the western half of the
santa barbara channel each afternoon evening thru fri.

Fire weather 21 824 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. Already saw some triple digit readings with single
digit humidities across the region earlier this afternoon. Hotter
temperatures are expected on Friday as a weak offshore wind
influence develops across interior sections in the morning,
resulting in more widespread triple digit readings across the
lower mountains, deserts, and interior valleys of slo county. In
fact, many portions of the antelope valley could see highs ranging
between 105 and 108 degrees on Friday, possibly reaching up to
110 degrees far eastern portions. In addition, there will be
widespread humidities falling into single digits across these same
locations. Due to the expected hot and unstable conditions along
with drying fuels, any fires that develop across interior sections
will have the potential for large plume growth. By late afternoon
and evening, expecting some gusty onshore winds to develop across
interior sections. By Saturday, temperatures and humidities will
moderate slightly, but there will be increasing onshore winds
during the afternoon and evening that will continue the elevated
to brief critical fire weather conditions.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect until 9 am pdt Saturday for
zones 670-673. (see laxmwwlox).

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

Hazard potential outlook (sun-thu)
No significant hazards expected.
