Area Forecast Discussion
National Weather Service Spokane WA
1215 AM PDT Sun Oct 4 2026

.KEY MESSAGES...

- Unseasonably warm temperatures and dry conditions continue through
Thursday of this week.

- Cold front passage on Friday will result in cooler temperatures,
gusty winds, and chances for rain.

&&

.SYNOPSIS...
Temperatures will remain unseasonably warm, in the 70s and low 80s,
through Thursday. Monday afternoon will be slightly breezy. It will
remain dry until Friday when a frontal passage brings lowering
temperatures, gusty winds, and a chance for showers.

&&

.DISCUSSION...
The upper level ridge over much of the western and central US will
continue to bring warming and drying conditions to the Inland
Northwest. The ridge will be at its strongest today (Sunday), and as
such, temperatures today and tomorrow will be the highest of the
week. High temperatures will be in the mid to high 70s, with some
places in the deeper basin areas reaching 80. These temperatures are
nearly 10 to 12 degrees above normal for this time of year. Low
temperatures are around 4 to 6 degrees above normal. On Monday, a
weak disturbance will pass through, flattening the ridge and raising
afternoon wind gusts to 15-20 mph through much of the forecast area.
Temperatures will drop slightly between Tuesday and Thursday, but
not much, still remaining unseasonably warm.

Conditions remain this way until Friday, when long term models show
a robust cold front moving through the region. While there is little
agreement in overall track and timing, ensembles show good agreement
in a steep drop in temperatures from Friday to Saturday, nearly 10
to 12 degrees. This will bring temperatures to right around normal
for this time of year, with highs in the low to mid 60s and lows in
mid to high 30s (lower 30s across sheltered valleys). Additionally,
there is agreement on gusty winds accompanying the low, with overall
gusts 15 to 25 mph and gusts 30 to 35 mph possible in the basin and
Waterville Plateau areas. While there is a chance for precipitation,
overall chances remain low, generally 30 percent or less in the
mountains and even lower elsewhere. Overall, expect a beautiful,
warm fall week across the Pacific Northwest through Thursday, then
cooler and unsettled weather Friday into next weekend. /AS
