Marine Weather and Tides
Raymond, 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 Increased marine clouds and cooler temperatures Thursday
and Friday will give way to warmer and sunnier weather over the
weekend before cooler and cloudier conditions return early next week.

Short term Tonight through Saturday... Water vapor satellite
imagery reveals a shortwave trough moving northeastward across
southwest oregon. Plenty of showers and thunderstorms developed in
advance of this feature across the oregon and washington cascades
earlier this afternoon and evening. Speed shear was rather meager
across the area today, which led to updrafts struggling to sustain
themselves. A thunderstorm in the southern lane county cascades where
0-6km shear was slightly greater likely contained the largest hail of
the afternoon based on doppler radar signatures. However, we have not
received any ground truth reports verifying whether or not large hail
was observed under any of the thunderstorms in which warnings were
issued this afternoon and early this evening.

Several convective allowing models including members of the href and
hrrr suggested thunderstorms were a good possibility for the portland
metro this evening. Several updrafts (in the form of towering
cumulus) went up around the portland metro during the time the sea
breeze arrived, but no individual updraft could sustain itself for
reasons not completely known at this point. A few models have
continued to suggest elevated thunderstorms are a possibility
between 8-11pm this evening as the marine layer deepens and is able
to interact with the instability still present above 5000 feet.

Given few signs this will materialize per latest radar and satellite
imagery, it appears the chance of thunderstorms is certainly
diminishing across most of the area. Will maintain a slight chance
of a thunderstorm through the late evening hours to account for the
uncertainty, though.

Otherwise, the marine layer is quickly spreading into the willamette
valley with temperatures already in the low to mid 60s in
kelso longview, mcminnville, salem and eugene. Expect marine clouds
to push well into the cascades by daybreak on Thursday with sunshine
returning in the mid to late afternoon hours. Temperatures will be
slow to warm with high temperatures likely only topping out in the
mid 70s. Expect a near repeat Friday before upper level high pressure
shifts over the region on Saturday and results in fewer morning
clouds and afternoon temperatures approaching 80f in the willamette
valley. Neuman

Long term Saturday night through Tuesday night... A surface thermal
trough strengthens along the n. Ca and s. Or coast Saturday night as
high pressure dominates inland, and offshore flow should keep marine
clouds off the coast Saturday night. A sunny start Sunday will allow
slightly warmer temperatures Sunday afternoon with high temperatures
remaining above the seasonal normals. Models are in excellent
agreement that an upper level trough will send a series of shortwave
troughs over the region Sunday night through Tuesday for increased
morning clouds and cooler afternoon temperatures. ~tj

Aviation Thunderstorms have developed over the cascades this
afternoon. As time progresses this afternoon, thunderstorms will
start to develop farther west, impacting ttd and pdx around 00z
this evening. Could even see a thunderstorm as far south as sle,
but better chance will be farther north. Thunderstorms should
start to diminish after 02z-03z. If a thunderstorm passes over a
terminal, expect a period of heavy rainfall reducing flight
conditions. Small hail and gusty variable winds are also possible.

Along the coast, marine stratus will hold through the rest of
today and tonight. With high pressure building over the coast,
may see CIGS lower to high ifr overnight tonight. Marine stratus
will also be pushing inland overnight, bringing MVFR CIGS to all
the inland terminals after 08z-10z. Will hold on to MVFR cigs
through much of Thursday morning, improving toVFR Thursday
afternoon as CIGS break up and lift.

Kpdx and approaches... PredominantlyVFR conditions through this
evening. Thunderstorms likely to develop near the terminal this
afternoon between 22z-02z. During this time, expect gusty,
variable winds from surrounding showers and thunderstorms. If a
thunderstorm moves over the terminal, expect a period of heavy
rainfall reducing flight conditions. Could also see small hail.

Overnight tonight, marine stratus will move into the terminal,
with CIGS around 2500 ft. MVFR CIGS should hold through much of
Thursday morning, lifting as CIGS start to break up by early
Thursday afternoon. -mccoy

Marine High pressure continues to sit over the NE pac, with
weak gradients over the waters through Friday. As the thermal
low starts to strengthen over norther ca this weekend, we could
see northerly winds ramp up to 20 to 30 kt over the weekend.

Seas remain around 3 to 5 ft through Friday as we remain under
relatively benign conditions. With winds ramping up this weekend,
seas may build up to 5 to 7 ft by late Sunday-early Monday, and
seas may become choppy. -mccoy

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.
