National Weather Service Spokane WA
214 AM PST Tue Nov 4 2025

.KEY MESSAGES...

- Active weather continues through the week.

- Periods of winter driving conditions over mountain passes.

- Breezy Winds Wednesday through Friday.

&&

.SYNOPSIS...
Several storm systems will impact the region through the week
with mild temperatures resulting in valley rain and mountain
snow. Winter travel conditions over mountain passes at times
through Friday. Winds breezy at times across the Columbia Basin
Wednesday through Friday as well. The weekend looks to bring a
break in the wet weather with continued mild temperatures for
November.

&&

.DISCUSSION...
Tuesday through Friday: Cooler than expected temperatures Monday
evening prompted a Winter Weather Advisory for the central Idaho
Panhandle mountains above 3500 feet through 8 AM Tuesday. Traffic
cameras have shown periods of light to moderate snow Monday evening
leading to snow covered roads at Lookout Pass. Rain will taper off
from west to east Tuesday morning as a brief upper level ridge
builds in behind the departing shortwave moving through the Pacific
Northwest. Most areas will see a break in precipitation late Tuesday
morning through the afternoon before another round moves in during
the evening and overnight, bringing additional snow to the high
mountains and rain to the lowlands. This progressive pattern will
continue to bring mostly beneficial precipitation through the rest
of the week. Small creeks and rivers may see some rises,
particularly Paradise Creek. Will also see some gusty winds around
30-35 mph in the Blues, Columbia Basin, and Spokane area much of the
week.

A period to watch is Thursday evening through Friday in the Cascades
as a shortwave trough moves through the region. Washington Pass has
a 70% chance of receiving 8 inches or more of snow between 4 PM
Thursday and 4 PM Friday, while marginal temperatures at Stevens
Pass keep the likelihood of 8 inches or more much lower at 10%.

Sunday through Tuesday: Models are still hinting at drier conditions
this weekend with a large upper-level ridge building over the
western US. With recent/forecasted precipitation, there will mostly
likely be lots of fog and low stratus in the region. /Butler

.AVIATION...
06Z TAFS: MVFR/IFR conditions will prevail as bands of rain
move through the region. There is an 80 to near 100 percent
chance of current conditions prevailing through at least 16z for
GEG- SFF- COE-PUW-MWH-EAT. Expecting improving conditions from
south to north in the Columbia Basin and Palouse in the late
morning to early afternoon hours as drier air comes off the Blue
Mtns/Idaho panhandle mountains.

.FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Confidence
is moderate to high for deteriorating conditions to continue
through tonight and into the early morning. Confidence is lower
for timing/if conditions improve.
