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 surface ridge offshore will maintain onshore flow
through the 4th of july. This will produce typical early summer
weather with mild temperatures, morning low clouds, and afternoon
sunshine. An upper level ridge will weaken the onshore flow and
produce a minor warming trend today and Friday with less morning
cloud cover on Friday. Stronger onshore flow Friday night will
bring more morning cloud cover on Saturday.

Short term Satellite imagery shows considerably less cloud cover
this morning than the same time yesterday. The seattle metro area is
clearing, as are the mountains, especially the olympics. Surface
pressure gradients have turned weakly offshore, which will aid in
the ongoing clearing. The combination of weaker offshore flow,
subsidence from the upper level ridge building, and the thinness of
the marine layer will result in remaining stratus evaporating over
the interior later this morning into the afternoon. The stratus will
hang on a little longer along the coast but the forecast still calls
for some afternoon sunshine there as well. With more sunshine and
warmer temperatures aloft, highs today over the interior will be 5
to 10 degrees warmer than Wednesday with 70s common. The coast will
also be warmer with some afternoon sunshine but high temperatures
will remain in the 60s.

The upper level ridge will move through the area tonight into Friday
morning. Surface gradients will be flat flat overnight into Friday
morning with the low level winds light northerly. This will confine
morning cloud cover to just the coast Friday morning. Temperatures
aloft do not warm much between 00z Friday and 00z Saturday with
model 850 mb temperatures around plus 15-16c. With the lack of
onshore flow Friday will be the warmest day in the next week. Highs
will be a couple of degrees warmer than today, in the 70s and lower
80s over the interior and near 70 along the coast.

Stronger low level onshore flow will return Friday night into
Saturday morning. Model surface gradients have the kuil-kbli
gradient peaking between plus 3 and 4 mb, the koth-ksea gradient
between plus 5 and 6 mb and the khqm-ksea gradient around plus 3 mb.

The marine push Friday night will bring stratus back into the
interior Saturday morning. Model cross sections put the marine layer
depth at 2000-3000 feet Saturday morning. Not deep enough to prevent
some afternoon sunshine especially with the weakening onshore
gradients. Highs on Saturday will drop back down to near normal for
the first day of july with 60s on the 60s and mid 60s to mid 70s
inland. Felton burke

Long term Previous discussion... Extended models in good agreement
through Monday with low level onshore flow continuing, zonal flow
aloft on Sunday and a weak trough moving through Sunday night into
Monday. The trough could provide enough lift for a light shower or
two on the coast. For the interior just a deeper marine layer. Ecmwf
is a little faster digging the trough offshore on Tuesday versus the
gfs but both models are dry. The ECMWF brings the trough inland late
Wednesday while the GFS keeps the trough offshore. All of these
differences are minor. Expect varying amounts of morning cloud cover
with afternoon sunshine for the interior through the period.

For the coast less afternoon sunshine. Highs will be close to
normal... 60s coast and 60s to mid 70s interior. Felton

Aviation Upper level high pressure will continue to move slowly
eastward today... Currently just off the coast but moving inland as
the day progresses. Flow aloft will remain northwesterly but will
likely become light this evening. Although the coast may struggle to
burn off stratus... Inland CIGS are already starting to break up with
many locations already reportingVFR conditions and those that
aren't should reach that mark by noon today. Generally clear skies
are expected for this afternoon into tonight.

Ksea... Satellite trends show that clouds are starting to break up
some over the terminal... Thus would expect CIGS to dissipate in the
18-20z time frame. Light south to southwest winds this
morning... Generally less than 6 kts... Becoming northwesterly around
20z this afternoon before becoming more northerly tonight. Smr

Marine High pressure offshore with low pressure east of the
cascades will maintain onshore flow of varying strength through the
week. The westerly push in the strait will probably again be a
little on the weak side during the day today... But there are hints
for SCA winds this evening and tonight... Thus will issue advisory
with morning forecast package. A warmer day on Friday looks to
result in a stronger push in the strait Friday evening. Inherited
forecast is backing away from gale solution... Favoring high end sca
winds... Which jives well with solutions from 24 hours ago and will
likely continue this mode of thinking... Leaving any SCA needed there
for future shifts.

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory for the central and eastern strait this
evening and tonight.
