Synopsis
Strong high pressure will persist through Thursday. The lowlands
of eastern washington and north idaho will be covered by low
clouds while the mountains remain mild and mostly clear. Chances
for precipitation will increase Thursday night into Friday with
unsettled weather expected through next weekend.

Discussion
Tonight through Wednesday... An upper ridge will remain in place
through Wednesday resulting in little change to the current
pattern. There will be one wave that tops the ridge and moves into
southern bc Monday night into Tuesday but given that this wave is
tracking to our north it should have little if any effect with
our current inversion. The stratus layer will continue to lie in
the 2500-4000 msl elevation range giving most towns cloudy skies
but good visibility with the stratus above the valley floors.

Cloudy skies will limit diurnal temperature changes to 2-4f for
most towns. The palouse, lewiston area, and parts of the idaho
panhandle continue to lie on the edge of the stratus with easterly
boundary layer flow. Continued a near persistent forecast here
with stratus and patchy freezing fog more prevalent in the
overnight and morning hours. Jw
Wednesday night through Sunday: the upper-level ridge will continue
to dominate our weather pattern Wednesday night and Thursday. Conditions
will remain dry and cool with widespread low clouds plugging the
columbia basin and most mountain valleys. Thereafter, models
continue to support the break down of the ridge and likelihood for
several rounds of precipitation.

The first shortwave arrives late Thursday night into the cascades and
spreads across eastern wa and N id Friday. This will be a light
precipitation event with QPF amounts generally around 0.15" or
lighter. Precipitation type will be quite challenging with the
moisture falling through the inversion. Models are not capturing
conditions under our current inversion so continued to trend
colder than guidance within the boundary layer allowing
precipitation type to fall as a combination of rain, freezing
rain, sleet, and snow. Again, this will not be heavy but will have
the potential to create slick conditions. Winds look to pick up
behind the cold front Friday afternoon evening to help mix out
the temperature inversions.

A strong jet will setup across the eastern pacific and into the
northwestern us in the wake of Friday's system. This will usher
the next rich slug of moisture and frontal system over the
weekend. There is decent agreement that the environment will be
cold enough to bring snow to the northern mountains and mix of
rain and snow in the lowlands. A second system arrives early next
week bringing another round of mountain snows and mix of rain snow
in the lowlands. If the models continue with the current trends,
this one will stand a better shot for lower elevation snow. Sb

Aviation
06z tafs: a layer of low stratus clouds over the lowlands and
valleys of eastern washington and north idaho's aviation area will
result in MVFR to ifr conditions at times. Some areas of freezing
fog resulting in locally low ifr visibilities may occur at times
as well. The top of the stratus deck is generally 1000 to 2000
feet agl. Pelatti

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.
