Synopsis
Limited shower chances will linger around the canadian border
this afternoon. Otherwise a jet stream remains over of eastern
washington and north idaho through the weekend, allowing for
breezy and dry conditions. High pressure builds over the
work week allowing for a warming trend, coupled with
continued dry weather.

Discussion
´╗┐today through Saturday night: limited shower chances near the
canadian border, the return to breezy conditions and seasonal
temperatures mark this period. This morning the next pacific
system is pushing onto the british columbia coast, propelled on a
120kt jet. The core of the lift, moisture and instability remain
north of the border. So only limited shower chances will dip into
northern mountains, mainly for this afternoon. The best threat
will be over the northern cascades north of the methow valley.

Some patchy fog will impact some of the sheltered mountain valleys
over the idaho panhandle this morning. Otherwise the rest of the
inland NW will be dry with increasing middle to high clouds. The
incoming system will increase winds through the day, with the most
notable increase near the cascade gaps where they a projected to
be between 10-15 mph.

By Saturday another shortwave skims by with the jet crossing the
inland northwest. Drier air comes with it allowing for a decrease
in clouds. Some guidance indicates some limited shower risk near
the immediate cascade crest and canadian border, but the risk is
too limited at this time to include in the forecast. More notable
with this next shortwave will be breezier conditions throughout
the region, with the jet bisecting the region and modest mixing.

Winds increase through the late morning to afternoon, peaking
around the 2 to 8 pm time frame before starting to subside. Speeds
of 10-20 mph will be common across the cascades out through the
columbia basin and spokane c'da and palouse in the aforementioned
time frame, with higher gusts. Potential impacts include elevated
fire weather concerns and choppy waters on area bodies of water.

Areas that are likely to see lighter winds include some of the
sheltered mountain valleys over northern washington north of a
line from conconully to republic to colville, into areas north of
bonners ferry across north idaho. Cote'
Sunday: onshore flow will continue into Sunday, albeit substantially
weaker than Saturday, as a deep marine layer hugs the washington
state coast. This is all in response to an upper level trough
sagging over the pacific northwest. While some upper level
dynamics rotate through our area on Sunday, total column water
vapor will be rather lackluster for this time of year. Only around
0.6 inches of pw will be available which will prevent any showers
from forming. However, there is still an outside chance a
sprinkle could develop over our northern mountains on Sunday, but
even that would be pushing it.

Monday through Saturday: the aforementioned upper level trough
slides to our east on Monday and will commence a warming trend for
the pacific northwest as high pressure builds in. In addition to
the warming temperatures, the airmass will be rather stagnant so
not expecting much in terms of wind either. As we go throughout
next week, the atmosphere will warm an additional degree or two
each day as we bake under the late august sun. By Friday of next
week, low 90s for the lower columbia basin with upper 80s
elsewhere for our lower elevations can be expected. Global
ensembles suggest the ridge of high pressure may begin to break
down next weekend however, near to above average temperatures
will likely continue for the weekend. Wilson

Aviation
06z tafs: westerly flow becomes established over the northwest
during the forecast period. A shortwave tracking within the flow
will bring an influx of mid and high clouds but no precipitation
to the terminals. Any shower activity will remain along the
immediate canadian border and points northward. Light and variable
winds in the morning become west southwest for the afternoon with
speeds of 6-10 kts. Sb

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.
