National Weather Service Spokane WA
1007 AM PST Wed Nov 19 2025

.KEY MESSAGES...

- Drier overall this week with slightly above normal
  temperatures.

- Active weather returns by the end of the weekend.

&&

.SYNOPSIS...
A quieter weather pattern is forecast for the upcoming week.
Temperatures will be cooler, but still above normal through the
week. A more active pattern is expected to develop by the end
of the weekend into early next week with valley rain, mountain
snow, and breezy winds.

&&

.DISCUSSION...
Today through Friday: The area stays in a split flow until the
end of the work week. Shortwave ridging controls today and the
weather looks dry, with some morning fog and low clouds, but
otherwise more sun. Another splitting trough pushes toward into
the west heading into Thursday. That splitting takes most of the
energy south and very little left further north, but some
limited shower chances will return to the Cascades and eastern
third of the WA ID. By Friday the are returns to a more zonal
flow and the primary precipitation chances will be found around
the mountain zones in that flow. Highs largely in the 40s and
lows in the upper 20s and 30s.

Saturday to Tuesday, the flow remains more zonal and a stronger
jet noses its way into the area along the US/Canadian border,
vacillating along before a trough approaches toward the new work
week. Precipitation chances will be found across much of the
region Saturday and Sunday, save for the lee of the Cascades
into Central WA in the downslope westerly flow. The incoming
wave expands and increased the precipitation chances area-wide
Sunday night into Monday, before starting to retreat toward the
mountains again Tuesday.

Snow levels average between 5-6kft through Sunday, drop to
around 4-5kft Sunday night night into Monday, then between
2-3kft by Tuesday as colder air start to come in. This will mean
largely mountain snow and valley rain to start, but by Monday
night into Tuesday a rain/snow mix or even a chance for all snow
drops to the lowlands. Mainly Washington Pass will see impacts
from snow through Sunday, with around 2-5 inches possible in
that 36 hour period. Then more moderate snow will be possible
Sunday night into Monday at Washington Pass with maybe 4-9
inches, with lighter amounts at other mountain passes. By
Tuesday about 1-3 inches will be possible at Stevens and
Washington Pass (less at Snoqualmie) and 1-3 toward Lookout.
Rain amounts away from the mountain zones look light at less
than tenth of an inch, with the best chances Sunday night and
Monday. Higher amounts are possible in the lower elevations of
the mountain zones, with a tenth to a third of an inch.
Temperatures will largely be in the 40s. Lows will largely be in
the upper 20s and 30s through Monday morning, then for Tuesday
morning there will be more 20s and some lower 30s in the L-C
Valley and perhaps near the Wenatchee River valley.

Looking a little further out again toward the Thanksgiving
Holiday weekend: there are some chances for light snow in the
lowlands, but the potential for anything too substantial will be
limited to the mountains. The better risk overall continues to
be around Thursday night into Saturday, as opposed to
Thanksgiving Day itself. Yet highs trend in most areas tin the
lower to mid-30s by Wednesday continuing into the weekend.

.AVIATION...
18Z TAFs: Expect VFR conditions to persist today under generally
decreasing cloud cover. A weak system approaches Wednesday
night, producing more mid level cloud cover which should again
limit coverage of fog/stratus development. That said, some
patchy fog and freezing fog may develop by Thursday morning.
Some chances for showers also developing after 12Z Thursday for
SE Washington and the southern Idaho panhandle.

.FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS:
Low confidence in fog development Thursday morning. Low to
moderate confidence in shower development/timing Thursday.

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

Confidence descriptors:

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