Langley, WA

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 An upper ridge will move east of the cascades tonight
and Wednesday. Western washington will be sunny with near record
highs, although a chance for showers with isolated thunderstorms
over the cascades will be present Wednesday afternoon and evening.

Onshore flow will bring cooler marine air inland Thursday and
Friday. High pressure aloft will cross the region Saturday, followed
by an upper trough early next week.

Short term Morning stratus receded as expected with partly to
mostly sunny skies over W wa. Starting to see some cumulus
development over the cascade crest... But not terribly impressed with
it. In coordination with surrounding offices... Have agreed to trim
pops there for this evening as well as eliminate thunder risk.

Turning focus to current temps... Most locations on average running a
few degrees cooler that obs from 24 hours ago and that lines up well
with forecast highs for the day.

Temp forecasts continue to look like tomorrow will see near-record
to record heat over the area as alterations to inherited forecast
were minor. That being said... Earlier quandary regarding the need
for any heat headlines ended up answering itself with a little
coordination. With conditions still cooling sufficiently during the
evening and overnight hours... This should be enough to help offset
any major concerns... Even though groups sensitive to prolonged
exposure to heat will want to use caution during the day Wed and
anyone finding themselves outside for a while will want to stay
hydrated.

Although it failed to materialize today... Models remain persistent
in showing that the prospects for showers and isolated thunderstorms
looks better for tomorrow over the cascades... Thanks to high level
moisture wrapping around the north side of the upper low entering
into montana and a dash of weak upper instability.

Afterward... More moderate conditions are on the way as stronger
onshore flow will develop Wed evening, as the leading edge of an
offshore upper trough moves into the pac nw. A cool, moist marine
layer should push inland Wed night and W wa will probably be more or
less covered by marine stratus Thursday morning, which should give
way to Sun breaks in the afternoon. Highs across the interior
lowlands should be back into the upper 60s and 70s, with mid 60s at
the coast. As the upper level trough passes through the northern
third of the CWA Thursday... Resulting in some slight chance pops
over much of the area... But the biggest impact will be temperatures
cooling even further with lowland locations dipping down into the
mid 60s to around 70. Smr

Long term As the trough exits... Upper level ridging will build in
once more... Moving inland Saturday and east of the cascades Sunday,
for more sunshine and somewhat warmer weather. Models coming into
better alignment with regards to follow-up trough for Monday... But
pop signatures on either model not terribly impressive... As one
would expect for summer. Like the trough discussed in the short term
forecast above though... Its main impact will be bringing temps over
the area down back into the mid 60s to around 70. Smr

Aviation Wrn wa will remain mostly btwn upper level ridges
centered over british columbia and near the W coast of NRN baja
ca, and upper level lows centered offshore and over mt. Light and
variable flow aloft will become light sly late tonight. Weak low
level onshore flow will become nearly flat overnight.

Meanwhile, expect generally ifr CIGS areas of MVFR vsbys to
overspread the coast this evening. Low clouds areas of fog will
reach the admiralty inlet area, the puget sound, and the sw
interior by 1200 utc. Overall, anticipating slightly less low
cloud coverage Wednesday morning compared to this morning.

Ksea...VFR. Will probably see some low clouds off to the west of
the airport again Wednesday morning. Winds will generally be light
and variable.

Marine
Weak onshore flow will become nearly flat overnight. Onshore or
westerly flow will return on Wednesday and strengthen for the
possibility of gale force winds over parts of the strait of juan
de fuca Wednesday night. High pressure offshore with lower
pressure east of the cascades will result in generally moderate
onshore flow Thursday through this weekend. Gale force winds will
be possible again over parts of the strait of juan de fuca
Thursday evening.

Sew watches warnings advisories
Wa... None.

Pz... Gale watch from Wednesday evening through late Wednesday night
for central u.S. Waters strait of juan de fuca-east
entrance u.S. Waters strait of juan de fuca.

Small craft advisory from 7 pm this evening to 1 am pdt
Wednesday for east entrance u.S. Waters strait of juan de
fuca.

Small craft advisory until 1 am pdt Wednesday for central u.S.

Waters strait of juan de fuca.
