  afternoons due to winds and low relative humidity. Any new
  or ongoing wildfires will be capable of spreading rapidly.

- Stable, cooler, and calmer conditions expected Sunday into
  next week.

&&

.SYNOPSIS...
Wildfire smoke continues to bring hazy skies and may keep high
temperatures cooler than currently forecasted. Low relative
humidity and gusty winds today and especially Saturday will
result in critical fire weather conditions. Temperatures will
cool into the 80s by Sunday and will stay there into early next
week before gradually warming again.

&&

.DISCUSSION...
Today through Saturday: A ridge firmly in place over the western US
is bringing yet another hot day to the Inland Northwest. High
temperatures today will be in the mid to upper 90s with triple digit
temperatures in the deeper Basin and Lewiston areas. Widespread
moderate HeatRisk remains over the forecast area, so all those
sensitive to heat should continue being cautious and have access to
adequate cooling and hydration. A strong thermal trough will result
in a breezy evening as the east-west pressure gradient across the
Cascades tightens this afternoon. Areas that will see the highest
wind gusts (20 to 25 mph) are the Columbia Basin, Waterville
Plateau, and Okanogan Valley areas. As a result, a Red Flag Warning
has been issued for these areas through late tonight due to
these wind gusts combined with high temperatures and relative
humidity values 10 to 20 percent. Elsewhere, expect wind gusts
10 to 15 mph.

As Saturday nears, a jet streak will strengthen over the area, with
500 mb flow nearing 50 to 60 knots. Additionally, a low pressure
system off the coast will usher in a dry cold front Saturday
morning. This cold air advection combined with steep low level lapse
rates will result in 30 to 40 kt winds at 700 mb mixing down to the
surface. The drier air moving in will keep relative humidities
across the Inland Northwest confined to 10 to 25 percent. Thus, a
widespread Red Flag Warning has been issued from 11am to 10pm
Saturday. These fire weather conditions could result in rapid fire
spread with any new or ongoing fires. Additionally, with wind gusts
of this magnitude, there is a risk for blowing objects, damage to
small trees, and localized power outages. High temperatures will
decrease by about 5 to 10 degrees between today and tomorrow, and
low temperatures will decrease by about 5 degrees.

Sunday onward: A series of low pressure systems will keep heights
lower off the PNW coast, allowing temperatures to fall into the mid
to high 80s for much of the area Sunday through Wednesday. These
values are right around normal for this time of year. Onshore flow
and the thermal trough will continue to bring breezy afternoons to
central and eastern Washington. Dry conditions will continue through
this time. By Thursday and into the beginning of next weekend, the
low pressure off the PNW coast will weaken and a broad ridge forms
over much of the western US. Long term and cluster guidance both
favor this ridge strengthening into next weekend. This will bring a
return of minimum relative humidity values in the teens, as well as
keep conditions dry with little to no rainfall expected across the
Inland Northwest through next weekend. The CPC reflects this, with
increased chances for above normal temperatures and below normal
precipitation. /AS

.AVIATION...
00Z TAFS: Expect mostly VFR conditions over the next 24 hours.
Regional wildfire smoke will occasionally bring MVFR conditions,
especially across the northern valleys of WA and ID. Winds will
remain elevated through the early evening with gusts of 15-25
kts before subsiding overnight. Winds will ramp up again late
Saturday morning through Saturday evening with gusts to 25-35
kts for Central WA sites like KEAT and KMWH and 15-30 kts
elsewhere.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Moderate
confidence in the visibility forecast at the TAF sites.
