Marine Weather and Tides
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.
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.

Synopsis Upper level ridging over washington will keep
conditions dry through Thursday. Surface high pressure over
southeastern british columbia will give low level offshore flow.
Warm conditions, with near-record to record high temperatures,
are expected through Thursday. An upper level low will approach
from the southwest late in the week bringing a return to
seasonably cool temperatures and an increasing chance of showers
Friday into the weekend.
Short term Upper level ridge axis will strengthen a bit over
central washington on wed, and surface high pressure over the
interior of british columbia tonight will spread into eastern
washington on Wed and Wed night. This will maintain dry easterly
flow and near-record high afternoon temperatures.
On Thursday, the upper ridge axis will exit eastward into the
northern u.S. Rockies, and a southerly marine surge will spread up
the oregon coast. The marine surge should reach grays harbor on
thu morning, bringing substantial cooling to the coast on thu.
Meanwhile, the interior i-5 corridor will have one more day of
near-record high temps on thu. Then on Thu night, cooler and more
humid marine air will strongly push into the interior. By fri
morning, all of the lowlands except perhaps near bellingham will
be under low marine clouds. Quite a few lowland locales could be
20+ degrees cooler on Fri afternoon than on Thu afternoon. That
is about as much day-over-day cooling as we experience around
On Friday, a closed low off the northern california coast will
start to wrap deeper moisture into the pacific northwest under the
influence of southeast flow aloft in the low's northeast quadrant.
Models seems to agree in wrapping a band of rain into southwest
washington on Friday, spreading northward on Friday night. Haner|
Long term From previous discussion: global model solutions,
including the us gfs, have all come around to the ECMWF solution
of the past few days. This solution is generally slower in moving
precipitation northward through western washington than the
earlier GFS solutions and has lighter precipitation amounts Friday
through the upcoming weekend. Highs on Saturday and Sunday will
struggle to hit 60 degrees and there will be a good chance of
showers under cloudy skies and a cold-feeling southwest breeze.
Shower chances will diminish early next week as high pressure
builds into the area from the west. By the middle of next week,
temperatures are expected to return to normal or perhaps a few
degrees above, and conditions will dry out.
The extended forecast represents a blend of the various model
Aviation Upper ridge over central washington for next 24 hours.
Light westerly flow aloft tonight, becoming southerly late
Wednesday. Thermal pressure trough will continue near the coast,
supporting dry low-level offshore flow. The air mass will be dry
and stable, with nothing more than a few cirrus clouds.
Ksea... Clear skies and a northerly component to the surface wind
for the next 30 hours. Haner
Marine The thermally induced low pressure trough is centered
along the oregon coast and there wont be any substantial changes
til Thursday. The thermally induced low pressure will move inland on
Thursday with onshore flow developing Thursday night and persisting
into the weekend. Haner

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
