Short term Today through Wednesday... Upper level trough will move
across the inland NW today. Overnight band of showers is exiting
northeast oregon and southeast washington this morning. Short wave
within the trough combined with upper level cooling and daytime
heating will produce scattered showers over mainly the mountains
this afternoon and early evening. Upper level ridge to return with
drier conditions for later this evening and Tuesday. Next band of
moisture crosses the cascades late Tuesday night and give widespread
light to moderate rain on Wednesday. Drainages coming out of the
east slopes of the washington cascades will need to be watched for
rising water levels due to Wednesday's batch of rainfall between 1/2
and one inch in that area. In addition, snow levels in the
washington cascades will be rising to between 3500 and 4500 feet for
additional snow melt potential. Rainfall amounts in other areas will
be up to 1/2 inch in the northeast mountains and less than a quarter
inch in the valleys.

Long term Wednesday night through Monday... Wednesday night and
Thursday a system will be moving through the area with rain likely
across most of the area though there will be just a chance of rain
in the columbia basin. Snow levels will start out at around 7000
feet and lower to around 4000 feet by Thursday afternoon. A trough
will be following the system Thursday afternoon and night. Rain will
taper off in the lower elevations Thursday evening but there will
continue to be a chance of rain and snow in the mountains through
the night. Late Thursday night and Friday a ridge will build over
the area through at least Saturday night and this will give us dry
and fair weather. By Sunday models have diverged greatly with the
gfs having a strong upper low and trough bringing rain and mountain
snow Sunday night and Monday while the ECMWF has a weak trough
crossing the area Sunday and Sunday night with light rain followed
by a ridge for dry weather on Monday. With low confidence in the
models have a chance of mainly rain in the mountains Sunday through
Monday with the rest of the area dry. Temperatures will be in the
mid 50s to lower 60s with 50s in the mountains Thursday and Friday
then warm to the mid 50s to mid 60s Saturday through Monday. Perry

Aviation Previous discussion... 06z tafs... GenerallyVFR
conditions should prevail over the next 24 hours. Some MVFR
conditions are expected at kpdt and kalw through 9z. CIGS will
mainly range from about 3k to 8k feet agl in the rain showers, but
could occasionally drop to between 2.5k to 3.5k feet agl in any
heavier showers. Cigs/vis should be improving overnight. The area
will remain under an upper level trough on Monday, with scattered
showers developing in the afternoon... Mainly INVOF kpdt and kalw.

Westerly winds then increase Monday afternoon, gusting to 20-25kts
at some terminals. 93

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
