258 am pdt Tue oct 24 2017

Short term Today through Thursday. High pressure will dominate
the areas weather with dry conditions. Patchy morning fog over
portions of the basin will give way mostly sunny skies and above
normal temperatures. The high pressure over california will weaken
some and sag south allowing for a disturbance to approach the two
state area Wednesday. Some showers are possible over the wa or
cascades and into portions of the blue wallowa mountains Wednesday
afternoon and evening. As the system pushes east the high pressure
will re establish itself Thursday and influence our areas weather
with continued dry conditions for all of the region. Above normal
temps can be expected that will climb into the 60s over the valleys
areas through midweek.

Long term Thursday night through Monday... Mid upper level
ridge of high pressure along the coast Thursday night places a
northerly flow aloft over the interior pacific northwest resulting
in dry conditions and clear skies. The ridge axis moves inland over
the cascades during the day on Friday for sunny skies. GFS model
forecast vertical temperatures profiles show sinking air associated
with the ridge in mid levels yielding an inversion that combines
with weak pressure gradients in the boundary layer that cold
potentially yield a period of stagnant air near the surface, which
would allow increasing an concentration of air pollutants in the
lower columbia basin and adjacent valleys which continues through
Saturday night. Cooler air in mid levels moves into the region on
Sunday helping to erode the inversion and allow mixing to occur in
the boundary layer across the lower columbia basin. We'll have mild
fall temperatures each day through the period with high temperatures
in the mid 50s to lower 60s in the lowlands and in the mid 40s to
mid 50s in the highlands. Polan

Aviation 06z tafs... An upper level ridge will keep conditionVFR
at all TAF sites through the next 24 hours. Skies will be clear
aside from a few cirrus clouds. The clear skies, light winds and
increased subsidence may result in some patchy fog development at
kpsc and kdls. May also see a few stratus clouds as well at kdls,
kpsc and kykm. For now will indicate 6sm with br and sct ifr lifr
clouds at kdls and kpsc, with few ifr clouds at kykm around and
after daybreak. Winds will remain under 10 kts for the next 24 hours.

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.
