Marine Weather and Tides
Bellingham, 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 Onshore flow will develop Wednesday and increase through
the end of the week. Areas of morning low clouds will be mainly on
the coast Wednesday--but marine clouds will increase Thursday and
spread farther inland. A few showers might develop over the cascades
Wednesday afternoon and evening--with a better chance of showers
Friday afternoon through Saturday morning. A weak ridge is likely to
build into the area Sunday while a front approaches the area--but
the front should stay north over british columbia.

Short term A few patches of low clouds and fog hung on into
the afternoon--mainly on the north coast and in the strait. Areas
of low clouds or fog should increase overnight on the coast and
in the strait again, and onshore flow will develop on Wednesday
with the marine layer deepening through Wednesday night. A few
showers might build up near the cascade crest Wednesday
afternoon and evening. After a stronger marine push Wednesday
evening, expect more widespread low clouds over most of the
lowlands Thursday morning. On Friday the marine layer clouds plus
additional moisture from a weak disturbance kicking north through
the area from oregon, should combine for a mostly cloudy day.

Showers might develop--most likely over the cascades: a few model
runs have had quite a bit of shower activity late in the week while
other solutions have kept the moisture south and east of the area--
the ECMWF today as precip over oregon and hardly any over wa.

Long term The hint of a little upper trough Saturday morning
with a deep marine layer might result in a few areas of drizzle
of light showers and then some afternoon sunbreaks. Whatever
happens, the mostly cloudy chance of showers type of forecast should
give way to a good chance of warmer and sunnier weather for Sunday
and Monday. That weak upper trough early Saturday should give way to
a weak ridge Sunday--with 500mb heights rising about 100m into
the upper 570s. But there wont be a ridge axis over the area--
the models show a front nearing the region and an upper trough
offshore early next week--but so far the front is only forecast to
effect british columbia while upper level heights stay high
enough for pretty good weather for western washington. So, precip
is not likely over our area from that front--but the tail end of
the front and onshore flow might very well result in marine
layer cloudiness at times.

Aviation Light east-southeasterly flow aloft this afternoon and
evening before turning southwesterly overnight as both an upper
level ridge over bc continues to work inland and as an upper level
low centered over nevada dissipates. The air mass is generally dry
and stable... Although low level moisture is expected to increase
along the coast and near the strait of juan de fuca overnight
tonight as onshore surface flow continues. This will lead to the
development of MVFR to possibly ifr conditions in these locations
while the remainder of W wa is expected to remainVFR with only a
few or sct high clouds present. As has been the pattern lately...VFR
conditions are expected to return to all locations by late Wednesday
morning.

Ksea...VFR conditions expected to continue over the next 24 hours.

Surface winds northwest 5 to 10 knots this evening and tonight
before becoming southwest early Wednesday morning... Turning more
westerly Wednesday afternoon. Smr

Marine High pressure will remain offshore through Saturday with
lower pressure east of the cascades, maintaining onshore flow. Small
craft advisory westerlies are likely in the central and eastern
strait of juan de fuca again late this afternoon through early
Wednesday morning.

Onshore flow still looks to be stronger Wednesday and Wednesday
night as models remain consistent with putting gale westerlies in
the central and eastern strait and small craft advisory winds in the
adjacent waters of admiralty inlet and the northern inland waters.

A gale watch remains in place for the aforementioned portions of the
strait and looks good. Will likely wait a bit before adding
headlines for the adjacent waters. Mcdonnal smr

Sew watches warnings advisories
Wa... None.

Pz... Gale watch from Wednesday afternoon 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 until 3 am pdt Wednesday for central u.S.

Waters strait of juan de fuca-east entrance u.S. Waters
strait of juan de fuca.
