Expect the flow to become light northerly on Tuesday due to building pres over british columbia and lowering pres over oregon.

Synopsis
A high pressure ridge will bring decreasing clouds, dry weather
and a warming trend Tuesday into Friday. The end of the work week
will feature high temperatures in the mid 70s to low 80s. A cold
front will arrive Friday night into Saturday with cooler
temperatures, breezy winds, and a chance for showers this weekend
and into early next week.

Discussion
Tonight through Thursday... An upper ridge off the coast will
continue to allow a weak wave in the form of a warm front to track
across eastern washington and north idaho tonight. Not much lift
or precipitation with this... Just a lot of mid level clouds with
isolated sprinkles or light showers mainly in the mountains. This
front exits on Tuesday... But residual low level moisture and
afternoon heating will likely lead to quite a bit of flat cumulus
over the region especially in the mountains. Wednesday and
Thursday the upper ridge moves over the eastern washington and
north idaho for generally clear skies and warmer temperatures.

Highs will warm into mid to upper 70s with the warmest spots in
the lower 80s. This is about 10 degrees above normal for this time
of year. Jw
Thursday night through Monday: anticipate a weather pattern
change for the weekend and into early next week. The warm and
dry weather will continue for Thursday night into most of Friday
with above normal temperatures, light winds and mostly clear skies.

A cold front will sweep in from the west and reach the cascades
by midday, pushing across eastern washington Friday night into
Saturday. This feature has been showing some consistency among the
models on its timing and is trending stronger with an upper level
trough fast on its heels. This will bring a good shot of showers
from the cascades into north idaho. Breezy westerly winds will
develop behind the front and lead to some downslope conditions,
limiting the rain chances across the columbia basin. More
instability showers are possible Saturday afternoon and evening as
the upper trough axis pushes through the region with more
enhancement over the mountains. By Sunday into Monday, models are
struggling on solutions. Each one is suggesting an upper trough or
closed low in the vicinity, but placement is all over the place.

Likewise, just a day ago the upper ridge was returning. Believe
the models are dealing with the pattern change and expect flipping
solutions in the short term. At this time, opting toward a more
troughy solution and will trend toward a cooler, albeit more
seasonal, showery and breezy forecast for the region as the we
embark on early october. Rfox.

Aviation
18z tafs: mid level clouds with CIGS above 7 kft agl will remain
over much of the region. Additionally more cirrus continues to
overspread this mid level cloud deck and should thicken through
the day. Significant precipitation is not expect with this front,
but some light sprinkles and virga will be possible mainly over
central washington. Jw

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
