Synopsis
Limited shower chances will linger around the canadian border
at times on through the weekend. A strong jet stream remains over of eastern
washington and north idaho through the weekend, allowing for
breezy and dry conditions, especially for Saturday afternoon. High
pressure builds over the work week allowing for a warming and dry
pattern.

Discussion
Today through Sunday: jet stream remains over eastern washington and
north idaho allowing for breezy conditions over the weekend. The
resulting downsloping characteristics east of the cascades brought
about by the zonal flow results in a generally dry forecast with
minimal pops located within close proximity of the british columbia
border. Some ridge amplification occurs off the coast allowing for
the flow to turn to a more northwest one on Sunday and a disturbance
drops down at the same time. This may be enough to tighten and
reorient the pressure gradient to favor northeast winds and as such
have bumped up winds in the okanogan valley for overnight into
Sunday morning to account for it and allow for the daytime highs to
show a slight dip in comparison to those expected today. Pelatti
Monday through Thursday... This portion of the forecast will be dominated
by a ridge of high pressure wobbling around in the eastern and
putting the pnw in a somewhat cool but dry northwest flow.

Temperatures will slowly increase Monday and Tuesday, as the ridge
intensifies y the middle of the week there will be a rapid warm
up Wednesday and Thursday. Afternoon highs will increase to the
high 80s to mid 90s which is 6-9 degrees above normal. The ridge
will keep the storm track to the north and east of the inland
northwest. Model guidance is hinting at a weak short wave
disturbance moving up from the south on Thursday. This wave would
drag some mid and upper level moisture into the region late in the
day Thursday. Right now confidence is fairly low, but if the wave
does move through the region it would result in increasing
chances of nocturnal convection Thursday night.

Friday through Sunday... A second low will drop out of the gulf of
alaska Wednesday and will take up position off the or wa coast
Friday afternoon. Guidance starts to fall apart a bit Saturday and
Sunday, but both the ensemble and deterministic models want to the
bring the trough through the pac NW sometime between Saturday
night and Sunday night. If this were to verify the labor day
weekend would start out very warm and very dry Friday and Saturday
and would end up cooler than normal, quite breezy gusty, and with
a chance of showers by Sunday night and Monday. Tobin

Aviation
12z tafs: a westerly jet aloft will continue to bring some mid
and high level cloudiness but no additional precipitation. Main
aviation concern for Saturday will be gusty westerly winds developing
after 18z and continuing through 03z. Strongest gusts will be
at keat which could be in the 30-40 mph range. Gusts 25-35 mph
will be more common around spokane, pullman, and lewiston.

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.
