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.

short term discussion updated.

Synopsis After a warm day Sunday, a pacific weather system will
move through the area tonight, bringing in cooler and cloudy
conditions, and a chance of rain tonight and Monday morning. A weak
ridge and seasonable weather returns Tuesday, followed by another
weak trough on Wednesday. Northwest flow then sets in for the second
half of the week, with another chance of light rain showers by
Friday.

Short term Tonight through Wednesday... Quick update this evening
to add some thunder chances to inland areas from SW washington south
to around mcminnville and aurora and to mt. Hood. The line of
showers associated with the front is currently producing lightning
as far south as lewis county, wa, and with as hot as temperatures
got today, expect there's at least some chance lightning could end
up extending further south. Models are not handling the convection
at all well, so areal coverage of thunder chances are a bit of a
guess for now. If the front manages to hold together enough further
south to produce showers, thunder can't be ruled out elsewhere in
the valley and cascade foothills. Bowen
upper trough and associated surface front over the eastern pacific
continues to move east southeastward toward the wa or coast. Surface
front will move on shore this evening, with a strong marine
push cool down after today's warm afternoon. Now seeing a few light
showers on klgx about 100 miles northwest of ast, which should reach
the northwest oregon between 03-06z and advancing inland thereafter.

Will see some late day clearing Monday as a weak ridge builds
inland. Another weak trough approaches and moves over the area
Wednesday, for increasing cloudiness and a slight chance of light
rain northern coast and cascades late in the day. Bright

Long term Wednesday night through Sunday. Wed night the 12z gfs
and 12z euro show a shortwave trough moving through the area. This
will keep an onshore flow into the area. The GFS is showing an
increase pops, while the euro has the majority of moisture staying
well into washington. However, a much deeper secondary trough is
showing on the gfs, which looks to enter the area starting around
fri morning, and looks to increase the precip chance sat. The euro
however is leaning towards a weak shortwave ridge pushing on shore
in response to a blocking pattern that could develop in the pacific
during the same time period. For the weekend the GFS has a weak
ridge dominating the area, still keeping a cooler onshore flow, and
a minimal chance for precip. The euro for the same time period has
the blocking pattern holding, still keeping cooler onshore flow, but
severely limiting the chance for precip in the area. 42

Aviation A weak front currently offshore will usher
in marine clouds and a chance for some light rain over the next
few hours. Expect predominantly MVFR conditions along the coast
through early Monday morning. Some of these lower ceilings may
push inland and temporarily result in MVFR CIGS at interior taf
sites between ~09-18z Monday. Any flight restrictions that do
develop should trend toVFR rather quickly after 18z Monday as
the lower atmosphere should destabilize rather quickly.

Kpdx and approaches... A weak front currently offshore will usher
in marine clouds and a chance for some light rain late tonight
and Monday morning. Expect predominantlyVFR conditions through
06z Tuesday, but CIGS could temporarily lower into high end MVFR
thresholds Monday morning. Neuman

Marine The northern waters have experienced more wind than
expected this evening so a small craft advisory was issued to
cover the next few hours. As a weak front moves across the waters,
expect winds to subside towards midnight. Weak high pressure
over the northeast pacific should result in northerly winds for
much of the next week. The main exception to this will be when
another weak front may briefly turn winds westerly to maybe even
southwesterly on Thursday. Neuman

Pqr watches warnings advisories
Or... None.

Wa... None.

Pz... Small craft advisory for winds until midnight pdt tonight for
coastal waters from CAPE shoalwater wa to cascade head or
out 60 nm.

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.
