More light to moderate snow will be likely late this afternoon and
this evening as a storm system moves quickly across eastern washington
and the idaho panhandle. A moist frontal system is expected to
stall over oregon and central idaho Saturday night Sunday before
moving back to the north Sunday night and Monday. This will have
the potential to produce moderate to heavy snow as far north as
highway 2. Temperatures will remain on the cool side of normal the
next 6 to ten days with mountain snow at times.

Tonight through Saturday night... A fast moving frontal system is
moving through the region this afternoon and will be out of the
area by early Saturday morning. Light snow began this morning as
a warm front moved through. Snow accumulations were very light
south of highway 2 and 1 to 2 inches up into the northern zones
from republic to sherman pass to metaline falls. More snow is
expected this evening and overnight as the accompanying cold front
moves through the region. Widespread accumulations of around an
inch and locally to around 2 inches will be possible with the
front. The cascade crest will see 2-4 inches. Slightly heavier
snow is expected for the idaho panhandle, the camas prairie and
the blue mountains as the flow becomes westerly with the front.

The idaho panhandle should see anywhere from 3-5 inches and
locally around 6 inches, the blues and camas prairie 2-3 inches
and locally around 4 inches. An area of concern will be east of a
line along highway 195 where 1-3 inches of snow will be possible
around coeur d'alene, moscow and near pullman by morning. This
would satisfy a winter weather advisory and one will be issued
through early Saturday morning. The front pushes east between
6-12z tonight bringing a quick end to the snow. The atmosphere
will destabilize behind the front on Saturday and with several
weak waves moving through the region there will be a chance of
snow showers through Saturday evening, mainly for the cascade
crest and near the id mt border. Additional accumulations should
be light. Temperatures will remain on the cool side of normal with
lows tonight in the teens and low 20s and high on Saturday in the
upper 20s. Tobin

Winter storm expected Sunday night through Monday across southern
wa and the central id panhandle...

Sunday and Monday: unsettled weather is expected as a trough moves
across the pac nw. Models show a surface low moving across the
region. Current models differ a bit on location, but it looks to
be around northern oregon... Maybe moving into portions of
southeast wa and the southern id panhandle. This low is fairly
strong and is not expected to weaken significantly as it moves

Have made some changes to the forecast... Mainly to chance of
precipitation and snow amounts. Portions of NE wa and the north id
panhandle will see little to no snow. The best chance of snow
will be across the palouse and east and south into southern
shoshone county, the lc valley and camas prairie as well as parts
of central wa. Snow accumulations would be fairly light Sunday,
an inch or less. The 2 spots that will likely see 2-3 inches would
be the blue mountains and the camas prairie.

Then Sunday night into Monday as the surface low begins to
influence us more, we will see more widespread snow move into the
region. Sunday night the snow would be across the southern
portions of our forecast area, and then just in time for the
Monday morning commute the snow will move northward towards
wenatchee, moses lake, spokane, coe. Snow will continue to fall
through the afternoon and then begin to push south and east
through the evening and overnight hours. The northern
counties... Okanogan, ferry, stevens, pend oreille, bonner and
boundary is likely to light snow accumulations. Meanwhile all
counties to the south of that will see light to locally heavy
amounts of snow... Depending on where you are. The heaviest snow
looks to fall across the blue mountains and to the north and east
towards lookout pass. Pullman, lewiston, the camas prairie will
likely need highlights. Given the easterly flow into the cascades,
locations west of moses lake into the waterville plateau,
wenatchee and plain area will see several inches of snow as well.

One forecast uncertainty is how much will the spokane area see.

The aftn forecast agrees pretty well with wpc that we will see
about 2 inches.

Sunday night as the energy begins to shear and move north snow
will generally come to an end for most areas. The one exception
will be southeast wa and the central id panhandle where they
could pick up an additional few inches.

Tuesday and Wednesday: the trough remains off the pac NW coast and
we get a weak ridge that bumps up into our area. Still have
mention of some snow across the region. It looks like northern wa
and id has the smallest chance of accumulating snow. The models
are showing a wave moving under the trough and into the area
early Wed morning which will provide a shot of light snow form
most locations.

Thursday and Friday: there is some model disagreement of what to
do with the trough... Keep it out there, push it through, keep it
dry, wet, tomato, tomatoe... It looks like the best chance of
precip will be across the id panhandle and perhaps portions of
eastern wa. But the confidence in this is quite low.

Temperatures through the forecast period will remain cold for
this time of the year. ... Nothing we haven't experienced the last
several weeks. More snow, more cold, more snow, more cold, more
snow, more cold, you know the drill. Nisbet

00z tafs: a weak cold front will move through the region this
evening, bringing light snow to kgeg ksff kcoe kpuw airports. Cigs
and visibilities should generally remain MVFR with this light
snow, which should end by about 07z. Behind this front, the winds
will become southwesterly, which should cause low stratus to form
for kgeg, ksff and kcoe, which will likely persist through
Saturday. Klws should remainVFR through the next 24 hours, but
could have some brief MVFR CIGS this evening. Kmwh and keat won't
see much if any snow. But their challenge is the formation of fog
behind the front. Not confident enough to put fog in kmwh. Keat
already has some fog with an MVFR cig, and computer guidance
suggests it will gradually lower overnight. Rj

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.
