.KEY MESSAGES...

- Warmest temperatures occur on Monday, with widespread Minor
  HeatRisk and pockets of Major HeatRisk in the deep basin.

- Tuesday sees increasing chances for critical fire weather
  conditions due to warm, dry, and gusty conditions.

&&

.SYNOPSIS...
Temperatures will remain above normal through the weekend
into next week, with the highest temperatures expected on
Monday. Fire weather will be a concern Tuesday with warm, dry
conditions and gusty westerly winds with a cold front passage.

&&

.DISCUSSION...
     STRONG DRY COLD FRONT PASSAGE TUESDAY...

Today through Monday: The ridge off the PNW coast continues to move
slowly inland, resulting in continued dry conditions and warming
temperatures. Temperatures today will peak in the mid to high 80s,
with much of the deeper Columbia Basin areas seeing the higher
temperatures. Tomorrow, the ridge will be directly over the state of
Washington, bringing the highest temperatures of the warm up.
Temperatures will be in the high 80s to high 90s, with isolated
places in the deeper basin having a chance at hitting triple digits.
These temperatures will be 10-15 degrees above normal for this time
of year and result in widespread Moderate HeatRisk with isolated
areas of Major HeatRisk. Moderate HeatRisk poses a danger to anyone
who is heat sensitive and does not have access to adequate cooling
or hydration. Major HeatRisk affects anyone without access to
cooling/hydration, as well as health systems and industries.
Isolated Major HeatRisk areas with the highest temperatures include
the Moses Lake and Wenatchee areas, which have been placed under a
Heat Advisory from Monday morning through evening.

Tuesday: By midday Tuesday, a dry cold front will move through the
region. A surface high off the PNW will strengthen as a low moves
southward from Canada into Montana. This will create a strong
surface pressure gradient, with many models showing a 10-12mb
gradient between SEA and GEG. This will result in regionwide
impactful westerly winds. Throughout much of the Inland Northwest,
there is a 50 percent chance and above for wind gusts reaching 40
mph. Winds will be stronger along the Cascade gaps, with both Moses
Lake and Wenatchee having a 40 to 50 percent chance of seeing wind
gusts up to 50 mph. These wind wind gusts could result in blowing
objects, damage to small tree limbs, and difficulty driving,
especially for high profile vehicles. Additionally, very dry
conditions will be present Tuesday, with minimum relative humidity
anticipated to drop into the teens throughout the region. This will
lead to critical fire weather conditions, especially along the east
slopes of the Cascades and in the Columbia Basin. Any new fires in
dry grasses could easily escape containment and become difficult to
contain. As such, a Fire Weather Watch has been issued for the
Okanogan Valley, Methow Valley, foothills of the central Cascades
Columbia Basin, Waterville Plateau, Palouse, Snake River, and
Spokane areas from Tuesday morning through evening.

Wednesday through Friday: Winds will decrease by Wednesday afternoon
and evening, but will still remain breezy with gusts up to 25 mph.
Temperatures will decrease by a few degrees through Wednesday, then
increase again through Friday as higher heights remain over the
area. Widespread Minor HeatRisk will continue through Thursday, and
then increase to Moderate HeatRisk on Friday as temperatures creep
back up. Cluster agreement on higher heights remaining over the area
stays unanimous through Friday. Conditions will remain dry, with no
precipitation expected through Friday. By the weekend, clusters
begin showing signals of a trough moving through. /AS

.AVIATION...
18Z TAFs: VFR conditions will continue through the forecast
period. Skies will be mostly clear and winds will generally be
light. Around 15-18Z, winds will begin shifting to the west
ahead of a dry cold front passage.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence
in VFR conditions through the TAF period. /AS

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

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