Area Forecast Discussion
National Weather Service Spokane WA
1041 AM PDT Sun Jul 13 2025

.KEY MESSAGES...

- Hot, dry, and gusty winds leading to elevated to critical fire
  weather conditions Sunday and Monday.

- Strong cold front from the north Monday delivering windy
  conditions. Brief damaging winds possible down the Okanogan
  Valley.

- A chance of showers and much cooler over the Idaho Panhandle
  on Tuesday. Gusty northeast winds in Washington.

&&

.UPDATE...
Morning update to add a High Wind Watch for Monday afternoon and
evening for the Okanogan Valley. Latest model guidance suggests
a better chance for shower and possibly isolated thunderstorms
along the leading edge of the cold front that drops south
across British Columbia Monday afternoon. Pattern recognition
and past events would suggest the potential that a surge of
strong winds and potentially damage wind gusts will develop for
at least a brief 1-2 hour period late in the afternoon in the
Okanogan Valley on Monday.

In addition, the Fire Weather Watch in effect for Monday has
been expanded to include the Okanogan Highlands, Spokane Area,
Palouse, and Snake River Valley. This is in response to models
trending towards a stronger shortwave and cold front. This would
lead to breezy winds with warm and dry conditions that may
result in critical fire weather conditions for these areas.

&&

.SYNOPSIS...
Hot temperatures today with high temperatures in the 90s to low
100s. Sunday and Monday fire weather concerns will increase due
to the hot, dry, and gusty conditions. Gusty northeast winds
will be in place on Tuesday.

&&

.DISCUSSION...
Sunday: High pressure over the region today will deliver
moderate to major heatrisk as temperatures warm into the mid 90s
to lower 100s. The ridge will begin to flatten late in the day
with increasing west to northwest flow aloft with the passage of
an upper-level front. Onshore flow will increase west of the
Cascades and set up a tightening thermal pressure gradient
across the Cascades which will spill into the Western Basin by
the evening. These winds will reach critical thresholds for fire
weather such that red flag warnings are in place from
Chelan/southern Okanogan to Douglas County where wind speeds
will reach 10-20 mph and gusts around 30 mph during the hottest
portion of the day and lowest humidity values. As the winds
spill further east into Moses Lake, Ephrata, and Wilbur it will
be in the evening hours as temperatures are starting to come
down. Not to say there will not be an hour or two of critical
fire weather conditions but highest probabilities for the
wind/low RH combo closer to 5PM will be where highlights exist.
The hot, dry, and unstable conditions region-wide will without a
doubt create elevated fire weather conditions. Mixing heights
in excess of 7-8k ft AGL will also allow infrequent gusts of
15-20 mph to mix down in the late afternoon and early evening
for many areas and could be problematic for any new fire starts.

Monday: There is A LOT of concern for weather conditions come
Monday and Monday night. All deterministic and ensemble models
are in agreement for high pressure to blossom over the Gulf of
AK and allow a robust shortwave to drop down its eastern flank
and swipe the Inland NW. Historically, this has produced strong
winds from the north for the Okanogan Valley and gusty winds
region-wide. There are still some finer details that need to be
sorted out including timing but as it stands right now, the wave
will drop into southern BC/northern WA around midday and track
to the east through North Idaho Monday night. Initially,
southwest to west winds will increase ahead of this wave and
associated cold front, then a robust punch of northerly winds
are expected to spill southward. The intensity of these winds
will be determined by 1) what time of day they descend southward
(ie how warm is it ahead of it to create the maximum thermal
difference) 2) how much rain falls in southern BC to enhance the
cold pool and ultimately pressure perturbation between BC and
the heat over the Basin. In past events when sufficient rains
fell in BC, winds have gusted 50+ down the Okanogan Valley and
through some of the north to south aligned drainages in northern
Washington. This may be the lacking factor for the extreme
winds...but something that we will continue to closely monitor
in future model hi-res model runs. Currently, the UW WRF has
gusts 35-40 kts for the Okanogan Valley which comes through
after 5PM. The latest HRRR which goes out through 5PM has gusts
of 30kts. So an extreme wind event does not come with high
confidence but nonetheless, the Okanogan Valley is going to blow
hard and spill into the Waterville Plateau and portions of the
Western Basin. Fire Weather Watches have been issued. There is
also concern for patchy blowing dust and tree damage. The
Okanogan Valley is favored due to its channeling and
orientation. For the remainder of the region, it will still be a
problematic day for fires given temps still in the 90s and dry
conditions with gusts 20-30 mph.

Going into Monday night and the upper-low shifts east, precip
and rain cooled air will pool in southeastern BC and southern
Alberta with some precip possibly expanding into far NE WA and N
ID. Concerns will shift toward a punch of northeast winds
coming through North Idaho and NE WA. As these northeast winds
descend to the southwest, gusts of 30-40 mph or possibly
stronger will be a concern overnight and into early Tuesday
morning. This unusual wind direction can result in tree damage
and power outages though confidence is moderate that any gusts
of 40 mph or stronger would be short-lived in nature.

Tuesday:  For Tuesday, the region will be in a moderate northeast
to southwest pressure gradient with blustery northeast winds.
Temperatures will be cooler (80s) with relatively higher
humidity values (20-30%) but still dry enough to have concern
for fire weather. Any new fires will be wind driven by atypical
wind direction (northeast) and have the potential to spread to
the south/southwest. The European Ensemble anomaly charts are
quite concerning for these northeast winds showing a large swath
of 90% of its members indicating significant anomalies from
forecasts produced for this 2-week period. These anomalies
stretch from N Idaho all the way to Kittitas Valley. Raw numbers
for wind speeds are 10-20 mph with gusts in the 30-35 mph
range.

Wednesday - Sunday: Wednesday will deliver less impacts as the
system moves off to the east and weak high pressure begins to
build on to the coast. Confidence Thursday into the weekend
rapidly decreases with nearly half of the ensemble members
showing weak ridging and half the members showing a trough.
Models are having a hard timing sorting out the track an depth
of the next low dropping down from the Gulf of AK and track (off
the coast, over the Inland, or just a glancing blow over the
ridge. Moderate confidence for temperatures to warm Wednesday
and Thursday then spread is 10-15 degrees in temps thereafter.

.AVIATION...
18Z TAFS: VFR conditions will prevail across the Inland
Northwest through 18z Monday. Expect high cirrus clouds at
times. Breezy west winds develop through the Cascade gaps with
gusts 20-28kts Sunday afternoon. In the Basin and Spokane area,
gusts will be closer to 20kts or less. Skies will be hazy to
smoky due to regional fires especially across the northern
portions of eastern Washington into North Idaho.  Stronger,
shifting winds will develop across the region Monday afternoon
into the evening.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence
that VFR conditions will continue at all TAF sites. Low
confidence on how smoke/haze will impact smaller airports from
Omak (KOMK) to Colville (KCQV) to Sandpoint (KSZT) today. Smoke
may drop visibility to between 6-10 SM for these airports. JW

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

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