.SYNOPSIS...
Temperatures for the remainder of the week into the weekend will
be at or below average. Highs in the 70s to mid 80s will be common
through Sunday. There will be occasional chances for showers and
thunderstorms along with periods of breezy winds during this
unsettled weather pattern. Drier weather will likely return Monday
with a good chance of warmer than normal weather toward the end of
August into the beginning of September.

.DISCUSSION...

Today: Temperatures today will be about 3 to 6 degrees cooler
across the Inland Northwest than we experienced yesterday as an
elongated upper level trough makes slow progress inland. The
morning will feature a good deal of cloudiness for north Idaho and
the eastern third of Washington as an upper level disturbance
emerges out of Oregon. The evening models aren't generating much
of a precipitation signal with this disturbance, but the NAM
advertises a band of mid-level instability from Pomeroy to Pullman
to Lookout Pass. The NAM's instability fields have had a decent
track record for predicting overnight and early morning showers in
recent weeks. So, a 20 percent chance of showers has been added
across the Palouse into the Silver Valley between 5 AM and 10 AM.

This afternoon, the upper low currently near the Olympic
Peninsula will migrate inland. Scattered showers and thunderstorms
over western Washington will spread into the Cascades by mid
afternoon. Brief heavy rain and lightning will be possible along
the Cascade Crest into the high terrain of Okanogan county this
afternoon into the evening.

Tonight into Wednesday: The Olympic Peninsula low will track along
the border of British Columbia/US border overnight into Wednesday
morning. The track of the low won't be favorable for showers in
central Washington with places like Wenatchee and Moses Lake
having a 10 percent chance or less for measurable rain.
Precipitation chances overnight into early Wednesday morning will
be as high as 30 to 50 percent for the Idaho Panhandle, the
Palouse, and far northeast Washington...areas less prone to the
Cascade precipitation shadow. By Wednesday afternoon, the chance
for showers will be limited to mountainous terrain as the upper
low exits the region. Southwest winds of 10 to 15 mph with gusts
of 20 mph or more will be common across the Columbia Basin,
Palouse, and West Plains with highs in the upper 70s to low 80s.

Thursday: Deep southerly flow on Thursday will lead to mostly
cloudy skies and seasonably warm temperatures...mainly in the 80s.
The most widespread precipitation Thursday and Thursday night
will likely be west of the Cascades as an upper low digs off the
coast of Oregon, but there will be enough mid and high level
moisture advection for the mention of showers. The National Blend
of Models generates a 20 to 40 percent chance of light rain
showers across central and eastern Washington Thursday into
Thursday night. By the afternoon, north winds of 10 to 15 mph will
be common with gusts up to 20 mph over the Columbia Basin,
Waterville Plateau, and L-C Valley. /GKoch

Friday through Monday: The closed low off the southern
OR/northern CA coast Friday morning pushes east Friday through
Sunday bringing an increased chance for showers region wide as
well as the potential for isolated thunderstorms. With the low
track the best potential for a wetting rain will be found over
Southeast Washington into the Central Panhandle Mountains. There
is some uncertainty with how quickly the system moves east. About
60-70% of the model ensembles take the low through the region on
Saturday before exiting on Sunday for warmer and drier conditions.
The other set are slower, suggesting Sunday could see some
showers as well. Right now the forecast favors the majority, with
Saturday being the day with the coolest temperatures and highest
precipitation chances for most locations. On Monday temperatures
rebound back to near seasonal values with dry conditions favored.
Ensembles continue to advertise a good setup for warmer conditions
for the middle to end of next week as upper level high pressure
strengthens over the western US. JW

.AVIATION...
18Z TAFS: There will be a 15 to 30 percent chance for showers and
thunderstorms overnight as a low that is currently over the
Olympic Peninsula moves inland. Areas most likely to see showers
include the Cascade Crest, Northern WA and Northern ID including
CQV and SZT, and Southeastern WA into the Central ID Panhandle
including PUW and LWS.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Confidence in
showers tonight into early morning Wednesday is low, so did not
mention in the TAFs for now. Thunderstorms may be embedded within
any clusters of showers that develop and may be added to TAF
updates for Lewiston, Pullman, and potentially Spokane and Coeur
d'Alene.

-----------------------

Confidence descriptors:
Low - Less than a 30 percent chance
Moderate - 30 to 70
percent chance
High - Greater than a 70 percent chance
