Synopsis A weakening front will through the area this evening
with rain changing to showers. Post frontal showers will end on
Tuesday. A second system will clip the southern part of the area
on Wednesday. An upper level low off the oregon coast Thursday
will dissipate Friday. The next system will arrive late next
Short term tonight through Thursday A front will push north
through the area this evening. Areas of light rain will change to
spotty showers tonight as the front pushes north into canada.
There might be an isolated thunderstorm off the central coast
behind the front tonight where it will be a bit unstable but the
threat looks too low to mention in the forecast.
Isolated to scattered showers will linger behind the front into
Tuesday, especially over the mountains. Showers should pretty much
end entirely Tuesday evening as weak high pressure aloft moves
overhead. Most of the area is looking dry on Wednesday as well.
Difluent southerly flow aloft ahead of an upper low off the oregon
coast will bring a threat of showers to areas south of seattle
later Wednesday. The chance of showers will expand to most of
western washington Wednesday night and Thursday as the upper low
offshore oregon slowly approaches the coast. Temperatures will be
near normal through the period. Schneider
Long term Friday through Monday A weak upper trough will
linger over the area Friday and possibly into Saturday with some
wrap around moisture and instability for a slight chance of
showers. There might be a dry 12-24 hour period later Saturday
into Sunday but it's hard to completely rule out a few showers for
now given the uncertainty and spread in the long range models. It
looks a bit wetter Sunday night and Monday as a pacific weather
system reaches the area but nothing out of the ordinary for this
time of year. Schneider
Aviation Radar shows rain across portions of the coast and
southwest interior. Rain will continue to spread into the region
from south to north later this afternoon into this evening. Rain

this evening with MVFR possible overnight, generally between 08z-|

Ksea...VFR conditions through this evening. Rain will arrive 23z-
00z and continue through 04-05z. Rain will become spotty in nature

following the front. Light E NE winds will become southerly by 00z
with sustained southerly 10-15 kts, gusts near 20 kts possible. Jd
Marine Onshore winds will continue through tonight as a frontal
system pushes through the area and an area of low pressure lingers
off the coast. Small craft winds will diminish for the strait
during the evening hours and continue for the coastal waters
through tonight. Winds will transition to southerly this evening
along the interior waters, with small craft winds into Tuesday.

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.
