Short term Tonight through Sunday. Satellite shows areas of fog
and low clouds in the columbia basin have dissipated this
afternoon as temperatures warm and airmass mixes out. Mostly
clear skies with some mid and high level clouds increasing from
the northwest. A cold front will move slowly across the region
from the north later tonight into Friday. Clouds will increase
overnight with mostly cloudy Friday. Should have some rain over
the washington cascades and northeast oregon mountains. Very light
rain possible over the columbia basin and further south into
central oregon. Flow becomes northerly Saturday into Sunday with
upper level ridge building in. Dry weather expected. Low level
north winds behind the front Fri night and Sat will inhibit fog
development. As winds subside and inversion starts to develop
expect patchy fog and low clouds late Sat night and Sunday in the
columbia basin and valleys. This will increase in coverage sun
night. 94

Long term Sunday night through Friday... Operational model
guidance and their ensemble families are in good agreement in
persistent upper level ridging over much of the pacific northwest
through at least Wednesday. Main concern in this pattern will be the
formation of strong near surface inversions trapping pollutants and
moisture with increasing air stagnation fog freezing fog issues
through mid-week. Diurnal temperature ranges in foggy areas,
primarily the columbia basin, will see significant compression with
spreads generally less than 10 degrees while areas outside the fog -
central oregon and mountains will see much wider swings. There are
still some model discrepancies beyond thanksgiving with the ec eps
generally much more progressive in breaking down the ridge than the
gefs GFS and have trended toward the more consistent slower
solution. This would leave fog concerns in place for those traveling
in the basin Wednesday night thanksgiving morning. An upper wave
approaches in the thanksgiving evening Friday morning timeframe and
will spread precipitation chances across portions of region with the
best chances along the cascades and in the northern blues. There are
still some uncertainties on the exact track with the system, but
gefs consensus would keep the basin mostly dry with westerly flow
aloft. Snow levels during this timeframe will be in the 4000 to 5000
ft range with minimal snow impacts to the major travel corridors
expected. There are no significant wind concerns with the ridge
overhead through a bulk of the period, and exact system track has
been too inconsistent to give too much weight to model wind speeds
for Thursday Friday, but nevertheless would expect an uptick in
speeds which should assist in scouring out any lingering
fog stratus. Peck

Aviation (18z tafs) Vfr conditions expected to prevail at most
terminals with light winds through the period. Morning fog along the
columbia will continue over the next couple of hours, with MVFR ifr
visibilities at kalw kpsc and kdls. This should improve by 20z to
22z. BrokenVFR ceilings to develop by this evening as a front
approaches from the north. 79

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.
