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.

Synopsis 23 904 pm.

A strong eddy into Sunday will support continued cool conditions
and widespread low clouds for coastal and valleys areas. Night to
morning low clouds will become less widespread and burn off
earlier in the day much of next week. This will support warmer
conditions for many areas, most notable across the valleys.

Short term (tdy-tue) 24 333 am.

Latest sounding around lax indicated the marine layer deepening to
around 3000 ft this morning. A tad higher than expected. Therefore
have adjusted inland temperatures to be similar to yesterday
for areas S of point conception and for the central coast. The
southerly surge that occurred yesterday will continue into today
and will help keep high temps a bit cooler than normal across los
angeles, ventura and sba coast and valleys. There will be a
significant cooling trend across the slo interior valleys as well
today with southerly wind component. Paso robles will be around
15 degrees cooler today with highs in the mid to upper 80s.

Latest goes-16 fog product imagery indicated low clouds well
entrenched across all coast and coastal valleys, and just started
to move towards paso robles from the west. Santa clarita valley
should be under cloud cover as well by sunrise. The inversion
above the marine layer remained fairly strong, so expecting clouds
to linger across many coastal areas through mid afternoon with
some coastal areas possibly remaining cloudy all day. The lax-dag
surface gradient was almost +2 mb stronger than 24 hours earlier,
which is a bit surprising based on latest MOS guidance. With the
southeasterly flow continuing this morning, have kept drizzle
across the sba south coast and adjacent foothills this morning,
but patchy drizzle could occur across some valley locations in los
angeles and ventura counties this morning. The SE flow across the
santa ynez mountains will also help to warm up areas like lompoc
due to the downsloping. Therefore while most coastal areas remain
in the 60s to lower 70s, lompoc and santa maria should reach the
mid 70s today.

Synoptically, the upper ridge will not be as amplified today, but
h5 heights remain similar today, with the upper ridge
strengthening from the south early this week. The marine layer
should begin to shallow up some, but low clouds are expected to
affect both coast and coastal valleys through Tuesday. With h5
heights increasing a few decameters Mon Tue and south winds across
much of the region, will turn northerly once again. A weak
sundowner is expected Tue evening for the sba south coast and
adjacent foothills. Valley highs will begin to rebound 5 to 10
degrees on Monday into Tuesday with warmest valley locations
reaching the upper 80s to lower 90s.A few degrees warmer than
normal. Coastal areas will remain mild due to the persistent
marine layer influence with low clouds scouring out by early
afternoon for coastal areas, with a few exceptions where clouds
could linger along the coast.

No major issues are anticipated with regards to winds through tue.

Moderate to strong onshore gradients will generate the usual gusty
afternoon evening southwesterly winds across the mountains and
antelope valley, but should be generally below advisory levels.

Except local gusty SW winds with gusts to 45 mph across lake
palmdale today and Monday afternoon and evening hours.

Long term (wed-sat) 24 335 am.

Latest 00z GFS and ECMWF models were in decent agreement wed
through Thu with both indicating a weak trough over much of the
west. H5 heights still remain around 588 dm. High temps will trend
slightly cooler Wed with more significant cooling the remainder
of the week. Models start to diverge some in respect to the trough
axis. The GFS hangs onto the upper trof with even lower h5
heights into Sat while the ec builds heights with upper ridging
nosing back into the area from the E pac. Will lean slightly more
toward the climatologically favored GFS (upper troffiness into srn
ca) for the extended forecast.

Overall, the marine layer regime should remain fairly constant
with night through morning low clouds across coast and most
coastal valleys through Saturday. NW winds across sba county will
bring a moderate sundowner, with a stronger sundowner for
Thursday. Wednesday should be the shallowest marine layer, then
increasing depth through the remainder of the week. Decent onshore
gradients should bring typical breezy to locally gusty S to w
afternoon and evening winds each day to the region, especially
over the mtns and deserts. Temps should be near normal to several
degrees above normal on wed, then cool a few degrees to near
normal to slightly below normal overall by Fri and sat.

Aviation 24 1222z.

At 0816z at klax... The inversion was around 3100 feet deep. The
top of the inversion was around 4700 feet with a temperature of
about 23 degrees celsius.

High confidence in kpmd and kwjf with moderate confidence
elsewhere for 12z tafs with TAF sites S of point conception in
MVFR category, otherwise to the north, lifr ifr status. Including
kprb. There is a 50 percent chance of drizzle at ksba from 10z to
16z. With 20 percent for other coast and valley sites through 17z.

Klax... Moderate confidence in 12z taf. There is a 30 percent
chance that MVFR CIGS will prevail through the this afternoon into
this evening. Any east component of winds are expected to remain
below 8 kts. 20% chance for gusts over 12 kts through 17z.

Kbur... Moderate confidence in 12z taf. Occasional 12010g15 is
possible thru 15z.

Marine 24 300 am.

Moderate confidence in current marine forecast. Breezy southeast
winds will continue across the coastal waters today with local
gusts to 25 kt possible near point conception. Otherwise there is
a 30 percent of SCA winds across the outer waters (mainly
northwest of point conception) by Tuesday night with more
widespread SCA winds likely by Thursday, possibly to include the
inner waters north of point sal and western portions of the east
santa barbara channel. There is a 30 percent chance of gale force
winds during this time focused across the outer waters northwest
of point conception). Patchy fog is likely at times next week.
