Area Forecast Discussion
National Weather Service Spokane WA
308 PM PDT Fri Aug 8 2025

.KEY MESSAGES...

- Drying and warming trend through Monday.

- Elevated fire weather conditions possible Monday through
  Wednesday with warm, breezy conditions.

- Cooling trend middle to end of next week.

&&

.SYNOPSIS...
A warming trend will provide more typical summer like conditions
this weekend, with the warmup peaking on Monday as high
temperatures warm into the 90s. Breezy winds will usher in a
gradual cool down for the middle to end of next week.

&&

.DISCUSSION...
Today through tomorrow: Shower chances this afternoon are much less
than yesterday with activity confined to the Canadian border (15%
chance) thanks to the much drier northwest flow behind the shortwave
trough that came through. We are entering a warming and drying trend
with a high pressure ridge building off the Washington coast.

Sunday through Friday: By Sunday, temperatures will be in the upper
80s to very low 100s. Heat advisories begin for central Washington
Sunday and spread east into eastern Washington and north Idaho. By
Tuesday, the upper level ridge begins to retrograde west, but
temperatures remain very warm in the 90s and low 100s. Fire danger
will increase Mon-Wed period with increasing Cascade gap winds and a
pair of shortwaves moving through BC. There are still considerable
differences amongst the GEFS members for the HDW (Hot, Dry, Windy)
Index so confidence in this detail is low. Ensemble agreement is
good for a sustained cooldown into late next week into the 70s and
80s. DB
