6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
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.

Synopsis A strong upper level ridge will maintain dry and
stagnant conditions across most of western washington through
Thursday afternoon. The ridge will break down on Thursday allowing a
cold front to bring rain late Thursday night and Friday. Another
frontal system will continue the wet weather pattern into the
Short term A big upper level longwave ridge remains over the
west coast this evening. It has weakened a little in the past day
and a weak upper level shortwave trough approaching vancouver
island this evening will traverse W wa tonight, diving SE across e
wa late tonight. IR imagery shows a lot of cloud cover between
about 128w and the wa coast that will move across the area
tonight with the shortwave trough. The cloud cover looks more
substantial than what earlier models had been showing so a minor
forecast update was sent to make it mostly cloudy tonight.
Clearing from the W is still expected later tonight and Wednesday
morning. The clouds should be mostly high level so there will
probably be some patchy fog still around late tonight and
After the upper level shortwave trough GOES by tonight, the upper
level ridge over the region will build on Wednesday. Then weaken
slightly on Thursday. This should produce a couple of days of
sunny weather with highs in the mid to upper 40s. Lows will likely
remain chilly both Wednesday night and Thursday night, with
readings mainly in the 30s. Still looking for patchy or areas of
The models have been trending slower and weaker with the weak cold
front that now arrives late Thursday night. The coast and n
interior should see some light rain before 12z 4 am and rain may
or may not reach seattle by that time. The frontal rain will
probably be over with by late morning, but the upper level
shortwave trough driving the front will be close behind, crossing
w wa Friday afternoon.
With the strong upper level ridge still in place through Thursday,
the lower air mass will remain quite stable under a strong low
level inversion. The lower air mass will remain stagnant, so the
air stagnation advisory will remain in effect through at least 2
pm Thursday. Air quality through puget sound remains mainly
moderate this evening, although there are a couple of spots
reporting in as unhealthy for sensitive groups. Kam
Long term Previous discussion from the 245 pm afd... The
pattern will be different from Friday on. Instead of a big upper
ridge, flow aloft will be westerly with upper troughs passing to
the north and clipping washington. Have used a blend of the gfs
and euro models, which means chance pops each day, with higher
pops around Tuesday when a stronger system appears in the models.
Highs will be 45-50 with lows in the 40s. Burke
Hydrology River flooding is not expected for the next 7 days.
Aviation High pressure is over the region and the air is stable
with patchy moisture--there are some clouds near the olympics and
kclm was showing ovc050 at 7pm. The hrrr shows some fog getting into
hoquiam before midnight, earlier than the current forecast so that
is one spot to watch tonight. Also, the hrrr is also showing a patch
of fog forming at kbli before midnight. Interestingly, the hrrr does
not show fog in the metro area, while the 12z 1km wrfgfs makes a
good case for widespread fog all around the puget sound area, over
a good part of SW washington, plus areas up through whidbey island
and the san juans and all through the admiralty inlet area and the
east entrance to the strait of juan de fuca--plus that blob on the
central coast that the hrrr also showed. Areas of fog should give
way to sunshine Wednesday afternoon--except perhaps for a few
patches near the water and olympia that might last all day.
Ksea... The forecast has fog starting at 13z 5am so we will watch the
dewpoints and obs tonight and go with that idea unless the moisture
starts to frost out--lowering the dew point.
Marine A ridge of high pressure extending from south-central
british columbia into eastern washington will give light offshore
flow to the waters tonight through Thursday. The light pressure
gradients and a strengthening temperature inversion aloft will
result in areas of fog over the southern portions of the inland
waters during the late night and morning hours. A cold front will
move east through the waters late Thursday night into Friday morning.
A warm front will brush the coastal waters on Sunday.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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.
