Short term Tonight through Friday night... The current pacific
system will continue to push into the pacific northwest tonight. The
warm front will continue to push east early this evening, then the
system's cold front will move across the area overnight. Thus will
continue to indicate high precip chances over much of our eastern
and southern zones through tonight. Meanwhile, the yakima and
kittitas valleys, and the lower columbia basin in washington should
become increasingly dry through tonight. Winds will increase from
the west overnight as the cold front passes through the region. On
Thursday, still expect scattered to numerous showers over our
eastern zones with isolated to scattered showers elsewhere. Snow
levels will be lower, roughly between 3400 and 4700 feet, but snow
accumulations will be limited by the showery nature of the precip
and the higher Sun angle. Winds will be breezy to windy across the
area. Winds may locally reach to around 30 mph sustained in the
gorge and the kittitas valley. For now will hold off on any
advisories for these areas. A dry northwest to north flow will
develop Thursday night as an upper level ridge builds over the
region. Thus will see lingering mountain showers end late Thursday
night with dry conditions for Friday. The dry conditions will
continue into Friday night, though the next pacific system may push
some light precip into the washington cascade east slopes late in
the period. 90

Long term Saturday through Wednesday... Forecast area will be
under a westerly flow Saturday with a very weak front passing over
the area and some limited mountain showers possible. Then the flow
begins to buckle as an upper level trough develops and deepens over
the pacific northwest which will enhance the shower activity Sunday.

The trough will shift eastward on Monday bringing showers to an end
and allow an upper level ridge of high pressure to build in from the
west. The ridge will persist through Tuesday but then gives way to
another upper level trough system on Wednesday and the increasing
chance of precipitation.

Aviation 00z tafs... MainlyVFR conditions expected over the next
24 hours. There will be some showers mainly impacting krdm, kbdn,
kpdt and kalw at least through the early evening in which brief MVFR
conditions are possible. Winds will be 10-15 kts overnight and then
stronger winds on Thursday at 15-25 kts and higher gusts.

Hydrology The latest pacific system will continue to provide
decent amounts of precipitation through Thursday, especially along
the cascade crest and over the eastern mountains. Also snow levels
will remain between 5000 and 7500 feet this evening, then gradually
lower overnight into Thursday. The higher snow levels this evening
will continue to allow for the melting of high elevation snow. Thus
the combination of rain and snow melt will cause rivers and streams
to rise through at least Thursday. Currently, river levels are
forecast to reach above flood stage at the grande ronde river near
troy and at the john day river near service creek. Thus flood
warnings have been issued for these mainstem river forecast points.

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.
