Synopsis
After a brief break, the next round of precipitation will reach
the cascades by Wednesday and spread across the inland northwest
Wednesday night into Thursday. Anticipate a rain snow mix in the
valleys with some significant snow in the mountains. A cooler and
showery conditions expected Friday into Saturday, followed by the
potential for more snow and rain by Sunday.

Discussion
Evening update: the weather is mostly dry, but some fog is out
about the columbia basin and some valleys. Satellite shows some
middle to high cloud spreading in and a southeasterly flow having
some impact on the fringes of the coverage of that fog stratus
area, going from dense to nothing in a few miles and then
switching places. The southeasterly flow should increase through
tomorrow so I expect some of that to continue to be eroded or at
least the fight for dominance will continue. I elected to handled
any fog with nowcasts this evening, rather than going with any
advisory given its nature.

A warm front will continue to lift in tonight and tomorrow
morning, with a wave of precipitation. This will be mainly light
and the better chances will be near the cascades and northern
mountains. I wouldn't rule out some passing the columbia
basin spokane c'da area and palouse in the morning too, but it
looks even lighter and rather transient and may not even measure.

Minor adjustments made to overnight lows and sky cover, with the
remainder of the forecast on track. J. Cote'

Aviation
06z tafs: a warm front lifts in tonight into early Friday,
bringing increasing middle to high clouds and some risk for light
precipitation. The southeast flow ahead of it will bring some
drier air toward the expansive areas of stratus fog across the
upper columbia basin into the spokane c'da area, but will be a
fight to see what factor will win out. Expect periodic MVFR ifr
conditions from eat mwh geg sff coe through much of the overnight,
but the incoming front and precipitation threat may allow this to
mix up a bit. -sn will be possible around eat, transitioning to
a -ra in the afternoon. A mix of snow rain freezing rain may also
slip by the other TAF sites in the 13-19z time frame, but this
looks rather light and transient so was left out of tafs for now.

Yet this will be monitored, especially any -fzra risk. General
improvement toward MVFRVFR conditions is suggested toward middle
to late morning. A cold front starts to approach from the west
later tomorrow, bringing another precipitation risk later into the
west. J. Cote'

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.
