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 24 256 pm.

Afternoon temperatures will warm slightly through mid week then
cool slightly into the weekend. Overnight and morning low clouds
will continue through the week.

Short term (sun-wed) 24 858 pm.

Ridging aloft is firmly in place across the area judging by the
latest satellite imagery. The latest amdar soundings from klax
indicate the marine layer depth has thinned by 500 feet at klax
and onshore pressure gradients are weakening as previously
surmised. Subsiding air aloft with the high pressure system will
press down on top of the marine layer and continue to weaken
onshore pressure gradients into Monday. A warming trend will
develop through Monday, warmest across the valleys and interior
sections. The exception could be for most of the central coast as
the southeast low-level flow that has created downslope warming
will subside and allow for cooler marine air to push into the
central coast Monday.

No updates are planned at this time.

*** from previous discussion ***
slight warming trend to continue into Tuesday before leveling off
or cooling slightly Wed with increasing west east gradients.

Better chance of a more complete coastal clearing those days as a
little north flow sets up in the afternoons, especially Wednesday.

Long term (thu-sun) 24 135 pm.

The ridge aloft will shift east Thursday as a trough pushes
onshore along the west coast. This will bring cooling to most
areas. Friday will be a mixed bag of temperature trends with
slo sb counties warming while la ventura counties cool slightly
with the trough axis just passing through there by evening.

Possibly some low grade sundowner winds Thursday and Friday
nights. Not as much confidence in the weekend forecast as the
ecmwf is faster building the ridge in from the west and warmer.

Probably not a huge difference either way though and of minimal
impact.

Aviation 25 0653z.

At 22z, the marine layer depth was around 1700 feet deep at klax.

The top of the inversion was around 4000 feet with a temperature
around 22 degrees celsius.

High confidence in 06z tafs for kpmd and kwjf with moderate
confidence elsewhere due to uncertainty in timing and flight
category of low CIGS vsbys. Flight category may be one lower at
times through 20z. Timing of flight category changes should be
generally within two hours. There is a 20 percent chance thatVFR
conds prevail at kprb.

Klax... Moderate confidence in 06z taf. There is a 20 percent
chance of ifr CIGS vsbys through 14z.VFR CIGS vsbys expected to
return between 16z and 19z.

Kbur... Moderate confidence in 06z taf. There is a 40 percent
chance of ifr CIGS vsbys through 14z.VFR CIGS vsbys expected to
return between 16z and 18z.

Marine 24 753 pm.

For the outer waters... Conditions will remain below SCA level
through Monday night. There is a 40% chance of SCA conditions
developing Tuesday afternoon and night, and a 60% chance by
Wednesday night through Friday, with a 30% chance of gale force
gusts Thursday into Friday.

For the inner waters north of point sal... Conditions will remain
below SCA levels through Wednesday then a 40% chance of sca
conditions Thursday into Friday.

For the inner waters south of point conception... There will be a
40% chance of SCA conditions Thursday and Friday across the
western santa barbara channel, otherwise conditions will remain
below SCA criteria.

Lox watches warnings advisories
Ca... None.

Pz... None.

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

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
