.SYNOPSIS...
A weather system arriving today and Tuesday will bring a chance
of showers and thunderstorms to the Inland Northwest. Dry, hot,
and smoky conditions are expected late in the week and could stick
around for a while.

&&

.DISCUSSION...
Today through Tuesday Night: Trough is moving onshore with
precipitation moving into western Washington. The precip will move
east through the day, into the Cascades over the next few hours
and by the afternoon into eastern Washington and the ID Panhandle.
Instability parameters do not look as impressive as it was showing
a few days ago, but there is still a 15-20% chance of thunder
today mainly across the US/Canadian border as well as down towards
the Camas Prairie. This threat continues through the night for NE
Washington and the ID Panhandle. Not expecting a lot of lightning
with this as the high resolution models are not showing much in
the way of higher reflectivity values. However, given the recent
dry conditions any lightning is concerning. On the plus side,
humidity values will be on the increase today as precipitable
water values increase to near 190% of average. Most locations have
a 20-30% chance of showers today and tonight with higher
probabilities in the mountains. The mountains is where wetting
rains (a 0.10 of precip of more) have the best chance of occurring.
Tuesday the best chance of precipitation will be across northeast
Washington, right along the WA/ID border and the entire ID
Panhandle. There is a 15-25% chance of thunderstorms in the
afternoon, mainly for the ID Panhandle.

Southwest to westerly winds will increase today and be generally
10-15 mph in the afternoon. There will be a couple of hours in
the afternoon and evening, generally between 4 and 8 pm where
there will be localized sustained speeds of 20 mph across portions
of the Waterville Plateau and along the Snake River Valley of WA.
Gusts will be 20 to 25 mph. Tuesday winds will be less than todays
speeds.

Given cloud cover and precipitation with the trough moving
through, temperatures today will be cooler than Sunday, actually a
couple degrees below average. Tuesday temps warm across central
WA, while they cool across north ID as the trough begins to push
out.

Smoke and haze will continue across the region, with the smoke more
confined to near and around the fires.

Wednesday through Saturday: Ensembles are hinting at another four
corners high developing for the period. It will bring another round
of hot, dry weather to the Inland Northwest. It is not expected to
last as long. Outside of the heat, there is not expected to be any
impactful weather. Winds will be light with diurnal shifts. As for
the temps, highs of 90 plus have a 90-100% probability starting
Thursday and lasting through the weekend. Friday and Saturday are
expected to be the hottest days of the period. There is 40-70%
probability of triple digits starting Friday for the Basin and
Okanogan Valley areas. Overnight lows will be in the 60s and low
70s.

Sunday and Monday: Ensembles begin to shift the ridge to the East
late Sunday into early Monday. It will begin a slight cooling trend
into the region. Unfortunately, a high off the coast will keep any
decent amount of moisture out the region. Highs for the region will
be in the 90s. Overnight lows will continue to be in the 60s and low
70s. /JDC

.AVIATION...
12Z TAFS: VFR conditions will prevail, however smoke from local
and regional wildfires may result in intermittent visibility
reductions to 6SM. An exception will be MVFR conditions possibly
overnight and into the morning for KLWS where nearby fires to the
east may result in visibility reductions to 5SM or less. A weather
system moving through today will allow for clouds to thicken and
lower from west to east. Southwest winds will increase and
become gusty in the afternoon with potential for very light and
spotty rain showers...after 16Z for EAT/MWH and after 22/23Z for
GEG/SFF/COE/PUW/LWS.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: There is low
confidence on how smoke will impact visibility across the Inland
Northwest.

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

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