Synopsis
A brief period of quiet weather returns Monday and Tuesday. A wetter
weather pattern is forecast for later in the work week with rain,
mountain snow, and breezy surface winds. Temperatures for the
weekend will be slightly cooler and below seasonal average.

Discussion
Today and Tuesday: a dry-stable northwest upper flow will precede
high pressure building into the inland northeast Monday and Tuesday.

As the ridge continues its eastward shift, an increasing southwest
upper flow will bring increased mid and high level cloudiness ahead
of the next incoming pacific trough. A weak mid-level trough,
however, moving southeast across eastern washington this morning
contributes to a broken layer of mid-level cloudiness lagging behind
the outgoing 500mb trough. This condition should dampen the
development of any low-level radiational cooling and reduce the risk
of widespread fog formation across region this morning. The valleys
of northern idaho still have the best chance of fog lingering
through the morning. Some patchy fog is still possible along the
purcell trench into cda and could extend west into the spokane area
before dissipating later this morning. With widespread clearing
continuing overnight Monday, there remains the risk of a repeat
possibility of fog formation Tuesday morning as radiation cooling
becomes more established throughout the region. Highs today and
Tuesday will be close to average and range from the mid 50s to mid
60s both days. Lows will be mostly in the 30s to low 40s with some
lows across the northern valleys dropping into the high 20s. Aky
Wednesday through Sunday... Once again models are a little slower
tonight. It still looks like a change to a more progressive
pattern with several short wave disturbances moving through the
region. The changes for tonight is that it looks like the first
short wave for Tuesday night Wednesday will get a lot it's energy
sapped out of it as a bit stronger wave follows Wednesday
afternoon. Model guidance is also showing a wave Thursday night
and one more Saturday and Sunday. This will result in a cool, wet
and unsettled pattern through the week and into next weekend.

Precipitation will ease into the region Tuesday night and Wednesday
as the warm front sags east of the cascades. And it now look like
the heaviest precipitation will be Wednesday afternoon and
Wednesday night ahead of the cold front. Snow levels will be up
around 7000 feet, with snow only at the higher elevations. Behind
the cold front snow levels will drop enough for accumulating snow
down to around 5000 feet. Some of the higher elevations of the
cascades up near the crest could see moderate snow accumulations,
but overall accumulations of 3-5 inches in the mountains will be
possible through Thursday morning. Showers will remain in the
mountains Thursday afternoon but the remainder of the area should
see a brief break in the weather. The precipitation will be on
the increase Thursday night with the next wave. However, by this
time we lose the deep moisture tap. The mountains will still see
moderate precipitation amounts, but across the lower terrain
accumulations should be lighter. Snow levels drop down to
4000-5000 feet and the mountains will have the possibility of
picking up moderate accumulations of snow. Highs in the 50s to
lower 60s Wednesday and Thursday then fall into the 40s and 50s
the remainder of the week. Winds will be elevated and gusty each
day, with gusts 20-35 mph each afternoon.

Things get a little cluttered Saturday and Sunday, but it does
look like yet another disturbance will move into the region
Saturday and Sunday. Right now the track of this storm is along
the cascades and south into oregon, giving the inland northwest
just a glancing blow. There is more confidence that the
temperatures will remain cool with gusty winds. Time will tell so
stay tuned. Tobin

Aviation
06z tafs: bkn to ovc skies will continue through the night for
geg-sff-coe-puw-lws. The cloud cover is expected to remain through
at least 15z... And have therefore backed off on the fog forecast
and lower sct cloud cover. Very light winds expected. Clouds will
thin with a sct deck abv 10k ft.

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.
