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 for southern washington and northern oregon coast.. A strong front will bring gale force winds as it drops southeastward across the waters Sunday and Sunday night. Coastal jet development could enhance winds even further within 20 nm of the coast. This front will stall near the central oregon coast early Monday before lifting back northward and spreading stronger southerly winds back into the waters late Monday and Tuesday.

Synopsis The upcoming week looks unsettled and wet. A weak upper
ridge will be over the pacific northwest today into early Sunday for
drying and stable conditions and for areas of persistent valley fog
and low clouds. The next system will slowly spread a front onshore
later Sunday and Sunday night for more rain and mountain snow, with
the lowest snow levels in the south washington cascades. The front
weakens later Monday then lifts north as a warm front for more rain
Monday night into Tuesday, but with rising snow levels. The warm
front will linger across the north part of the forecast area the
remainder of Tuesday and Wednesday. The next cold front moves through
on thanksgiving. A little drying early next weekend will be followed
by more precipitation the second half of next weekend.
Short term Tonight through Tuesday... Dense fog has developed in
the southern willamette valley with eugene less than a quarter mile
and corvallis at a quarter mile. This led to the issuance of a dense
fog advisory for the south willamette valley. Expect a dense fog
advisory will be needed for the rest of the willamette valley within
the few hours, but would like to wait until the observations support
the dense fog before issuing the product for the central and north
willamette valley and clark county. Some hints of this development
further north have already begun with 1 mile at kspb and khio and 2.5
miles at ksle. In addition, temperatures in the central and south
willamette valley will fall to near or below freezing tonight which
may lead to some freezing fog, especially in the outlying areas. Not
overly concerned about impacts to the roads given current ground
temperatures, but some bridges and overpasses may see slick spots.
previous discussion follows...
attention then turns towards the next approaching frontal system. It
should start to spread some precipitation onshore in the north later
on Sunday, then slowly sag south for more substantial rain Sunday
night into Monday. The front moves enough to reduce the threat of any
significant flooding. The front will also be accompanied by some
strong south winds ahead of the front, especially along the coast,
but some breezy conditions inland as well. Snow levels may be low
enough for a while in the south washington cascades that could
produce some decent snows above about 4000 feet or so Sunday night
before snow levels rise even there.
After the front weakens and stalls near lane county Monday afternoon,
it lifts north through the forecast area Monday night and then stalls
across the north part of the area Tuesday, especially affecting areas
north of salem with more rain.
All in all, Sunday night through Tuesday look wet and unsettled.
Long term Tuesday night through Saturday. Models in some
disagreement for this time period. The warm front from Tuesday
lingers some and lifts a little north Wednesday for some
precipitation around, followed by the main front moving through on
thanksgiving for a decent shot of rain. After some lingering shower
Friday with snow levels trying to stay above the passes, there could
be a little drying early next weekend before the next system
approaches. Bishop tolleson
Aviation The ifr stratus and fog did eventually clear from the
willamette valley late this afternoon. However, it is quickly
filling back in this evening. Expect all of the inland TAF sites
to see ifr conditions develop over the next few hrs. Expect
plenty of fog early, with some visibilities 1 4 mile or less.
Increasing southerly flow late tonight into Sun morning may
result in a transition away from fog and more toward low stratus.
Ifr conditions to persist through much of the morning, before
trending toVFR for the afternoon. There should be enough light
easterly flow at the coast to keepVFR conditions in control
through tonight and Sun morning.
A strong front will spread rain and MVFR or ifr conditions onto
the coast late Sunday afternoon and evening. There will also be
strong southerly winds developing at the coast, with gusts of 35
to 45 kt possible. The front will begin to spread into the
interior lowlands late in the evening, but expectVFR to prevail
through around 06z mon.
Kpdx and approaches... Expect ifr fog or low stratus to form
between 06z-09z and persist through mid-morning sun. Conditions
should improve toVFR during the late morning. Pyle
Marine No significant changes required to the marine fcst this
evening. The 00z NAM and GFS runs have kept good continuity with
prior models runs. A strong front is still on track to spread
gale force wind gusts of 40 to 45 kt across the waters Sunday and
Sunday night. Winds will increase first across the outer waters
late tonight, but these stronger winds will be slower to spread
into the inner waters and likely not arrive until Sunday morning
or midday. Left the timing of the gale warning intact for all
zones, but there is a decent chance it will need to be extended
past Sunday evening as latest model guidance suggests gale force
winds will continue past 10 pm, particularly across the central
oregon waters. In addition, coastal jet development will likely
enhance winds within 20 nm of the coast, and we could see some
storm force gusts of 50 kt within this region. Confidence is low
enough at this point that will continue to mention the
possibility in the forecast, but continue with a strongly worded
Either way, seas appear likely to top out near 20 ft, possibly a
touch higher briefly, Sunday evening. The aforementioned front is
forecast to stall out near the central oregon coast late Sunday
night or early Monday morning before lifting back northward on
Monday. When it does so, expect high end small craft advisory to
low end gale force southerly wind gusts of 30 to 35 kt to spread
northward across the waters. This should also result in seas
climbing well into the teens once again early next week where
they look to linger through at least thanksgiving. Pyle neuman

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.
