300 am pdt Sat mar 25 2017

Short term Today through Monday... A cold front has left the area
and is in idaho this morning. Behind it, a trough is moving into the
area and will be crossing the area today. There will be enough
moisture and instability for scattered rain and snow showers in the
mountains with snow levels around 4000 feet. Most of the lower
elevations will have isolated rain showers though the columbia basin
should remain dry. Rain and snow amounts will be fairly light with
less than a tenth of an inch of rain and up to an inch of snow in
the mountains. The columbia basin should have winds of 10 to 20 mph
this afternoon though winds will be lighter elsewhere. Tonight the
trough will move into idaho and weak ridging with a westerly flow
aloft will lead to a fair and dry night with partly cloudy skies.

The next weather system will move into the area Sunday morning with
likely rain and mountain snow above 5000 feet mainly in the
afternoon and Sunday night. Rain amounts look to be up to a quarter
inch in the lower elevations and up to an inch in the mountains.

Above 5000 feet, the mountains could get 3-5 inches of snow. Sunday
afternoon will see 10 to 20 mph winds in central oregon and the
grande ronde valley. Behind this front another trough will move into
the area and keep another chance of rain and mountain snow above
4000 feet. As with today, rain and snow amounts will be fairly light
on Monday. Temperatures today and on Monday will be in the mid to
upper 50s in the columbia basin with mid 40s to mid 50s elsewhere.

Sunday will be in the mid 40s to mid 50s. Perry

Long term Monday night through Sunday... The extended period
continues to look unsettled in a progressive flow aloft. The cwa
will be in between weather systems at the start on Monday night and
Tuesday, but then another weather system will move into the region
on Wednesday. The GFS is the outlier model and keeps it mostly dry,
while the canadian and other long range models show a wet weather
system to move through by midweek. Have therefore made just a few
changes to previous forecast of chance to likely pops. The unsettled
pattern then persists through the end of the extended period. There
may be a stray thunderstorm in the afternoons, but decided to not
mention it in the extended due to uncertainty and that it is too far
into the future. Temperatures will be near normal and winds will be
breezy at times... Especially in central oregon and north central
oregon and on the ridge tops elsewhere. 88

Aviation 12z tafs...VFR conditions will prevail today with
general improvement in the weather through tonight. There may be
some mountain showers but with little effect on any of the taf
sites. Winds will be light this morning... But then it will become
locally breezy this afternoon with speeds of mostly 10-20 mph this
afternoon. Winds will become light again tonight. 88

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.
