Marine Weather and Tides
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

455 am pdt Thu jun 22 2017
Aviation discussion updated...
An upper level high pressure system will bring well above normal
temperatures to inland areas of southwestern california through
Monday. An upper level trough of low pressure should then move
into the area Tuesday and Wednesday for a cooling trend. Skies
will be mostly clear for the most part during the period except
for some night and morning low clouds and fog for coastal areas.
Short term (tdy-sat)
three fairly similar days in a row slated for southern ca.
Temperatures will be the main point of discussions as the
interior will continue to bake under relentless heat while at the
beaches a stubborn marine layer and moderate sea breeze will keep
max temps there a degree or two below normal. There is a very
linear relationship with MAX temps from the beaches to the vlys.
Lax yesterday was 73... Downtown la was 82 and pasadena was 95.
Today through Saturday a large hot upper high will be centered
over california. 500 mb hgts will be around 593 dm through the
period. Onshore flow to the east will remain constant through the
period but there will be offshore trends from the north and by
Friday morning there will be actual offshore flow.
The marine layer is about 800 feet deep at klax and about 1400
feet deep at vandenberg afb on the central coast. Marine layer
stratus is slowly filling in and by dawn there should be stratus
at all the coasts and the lower coastal vlys. The NAM shows an
increase in onshore flow this afternoon and that would result in
slow to locally no clearing at area beaches but the nam
initialized very poorly and think its solution is not trustable.
Will go with clearing much like Wednesday. There will be similar
clouds Friday morning. On Friday night there will be a north push
which will bring a weak sundowner to the sba south coast as well
as the i-5 corridor. These north winds will likely keep sba south
coast skies clear Friday night... Otherwise look for a similar
Heat warnings continue for the la mtns and the antelope vly.
Advisory level heat will continue through the period for the vta
and sba mtns... The santa clarita vly and the cuyama vly. There
will be little change in temps from Wednesday readings today and
Thursday... There might be some warming Friday as the north winds
add a little compressional warming to the mix.
Long term (sun-wed)
looks like one more day of real heat on Sunday. The ridge actually
slides a little to east but hgts remain at 593 dm. The GFS keeps
max temps the same while the ec has a little bit more of an
offshore push and actually warms things up a bit making it the
warmest day of the next 7. Gave a small nod to the ec and bumped
temps up a degree or two from Saturday. The heat products look
good through Sunday.
Both the ec and GFS agree that the ridge will break down Mon and
tue. There should be some cooling each day away from the beaches
(which will see little or no change from the previous days. The
biggest drops will be felt in the vlys where the sea breezy will
finally be able to reach.
Disagreement for next Wednesday. The ec brings in a little ridge
while the GFS continues the trofing. Coordination and
collaboration between the surrounding offices resulted in a
preference for the cooler GFS pattern.
Aviation 22 12z.
At 0930z at klax... The inversion was around 900 feet. The top of
the inversion was around 3000 feet with a temperature of about 29
Overall... Moderate confidence in the tafs for coastal sites and
high confidence for the other sites. Reduced CIGS and vsby at
coastal sites this morning will improve by midday though MVFR
conditions may linger into the afternoon. Conditions at all
coastal locations will likely deteriorate again by late tonight in
a similar fashion as last night. Otherwise and elsewhereVFR
conditions will prevail.
Klax... Moderate confidence in the current taf. Lifr ifr|
conditions will waft in and out at klax near daybreak with a
twenty percent chance of vlifr conditions 13z-15z. Conditions
will improve by midday but may linger as MVFR before clearing to
vfr. Conditions will deteriorate again after 23 02z. East winds
greater than 7 knots are not expected.
Kbur... High confidence in the current taf.VFR conditions will
prevail through the forecast period.
Marine 22 200 am.
Widespread dense fog with visibility less than one mile will
likely impact the coastal waters into the weekend though with
improved visibilities each afternoon.
Winds will remain below small craft advisory (sca) level through
Friday then increase to above SCA levels Saturday through Monday.
A 2-3 foot south swell will last through much of the week and
poses a risk for breaking waves nearshore. This is especially
hazardous due to the dense fog. People boating or kayaking near
shore should use extra caution this week. A small (2-3 feet)
short period swell will impact the santa barbara channel and santa
monica basin over the weekend.
Fire weather 21 545 pm.
The prolonged heat wave combined with low humidities and gusty
afternoon onshore winds will continue to bring elevated fire
danger to inland areas into this weekend. Hot and unstable
weather conditions through this weekend will bring a continued
threat of plume dominated fire behavior in areas where there are
lighter winds, especially interior areas where mixing heights of
15,000-20,000 feet will be possible.
The threat of active nighttime burning will continue across the
mountains and foothills through at least Thursday night with
widespread lows in the 70s and poor humidity recoveries. Minimum
humidities are expected to range from 15 to 30 percent coastal
valleys to 3 to 15 interior areas including the mountains, lowest
across the antelope valley and higher elevations through Thursday.
As the upper level ridge of high pressure weakens some Thursday,
there is expected to be a stronger onshore flow with elevated fire
weather conditions continuing into Thursday and Friday for all
interior areas. Critical fire weather conditions are likely
across the los angeles county mountains and the adjacent foothills
of the antelope valley on Thursday, with a red flag warning posted
for this area from 9 am to 9 pm. These areas will likely
experience the strongest onshore winds(especially through the
highway 14 corridor), generally gusting between 25 and 35 mph,
with localized gusts up to 45 mph in the foothills of the antelope
valley near lake palmdale. The winds are expected to spread
across the warning area by mid morning first at higher elevations
and to the rest of the area by early afternoon and continue into
the evening. Minimum humidities during this time will be 3-15
percent with poor overnight recoveries. Similar winds are expected
Friday, however humidities for this area will likely be up 5 to
10 percent save for possibly higher elevations resulting in
elevated to brief critical fire weather conditions. Hot, dry and
locally windy conditions will likely continue into the weekend.
Lox watches warnings advisories
Ca... Heat advisory in effect until 9 pm pdt Sunday for zones
38-52-53-88. (see laxnpwlox).
Beach hazards statement in effect through Friday evening for
zones 40-41-87. (see laxcfwlox).
Excessive heat warning in effect until 9 pm pdt Sunday for
zones 54-59. (see laxnpwlox).
Red flag warning in effect from 9 am this morning to 9 pm pdt
this evening for zone 254. (see laxrfwlox).
Hazard potential outlook (sat-wed)
hot temperatures with potential heat impacts will continue for
the antelope valley and san gabriel mountains through Sunday and
possibly other areas as well.
