Area Forecast Discussion
National Weather Service Spokane WA
1224 AM PDT Fri Aug 1 2025
.KEY MESSAGES...
- Scattered, wet thunderstorms Friday. Heavy rainfall, small hail,
gusty winds and lightning main threats.
&&
.SYNOPSIS...
Scattered showers and thunderstorms Friday will be similar to
Thursday. The main threat will be flash flooding on recent burn
scars. Showers and cooler weather expected through the start of
next week.
&&
.DISCUSSION...
Today and tomorrow: Expecting another round of thunderstorm
development starting late Friday morning in the INW as a weak wave
moves through the region. With weak to no capping inversion in place
tomorrow, storms will quickly fire with a bit of heating. With PWATs
up to 200% of normal later today, I issued another flash flood watch
for the burn scars in Chelan, Okanogan, Ferry, and Stevens Counties.
The CAPE concentration will be a bit lower in the storms today, so I
did not issue another red flag warning for lightning. With that and
the even higher PWATs, the thunderstorm cores will be very wet. The
threat for strong outflow winds is lower with these factors in mind.
There is still the possibility for new fire starts outside of the
thunderstorm cores. Temperatures today will reach into the mid 80s
to mid 90s. Thunderstorm coverage Saturday looks lower as the best
moisture is confined to northeast Washington and north Idaho.
Sunday through Friday: Sunday looks much drier in the INW as a
transient shortwave ridge builds ahead of another trough developing
offshore. Temperatures will still be mild in the 80s and 90s with
breezy afternoon winds. This trough quickly moves inland Monday
bringing more chances for showers and weak thunderstorms to the
region. Temperatures will be cooler Monday in the 70s and 80s.
Temperatures start to rebound Tuesday into the 80s as this trough
shifts into northwest MT and a weak ridge builds. The mid to late
week period will feature a slow warming trend back towards the 80s
and 90s with unsettled conditions in the mountains. There are hints
of the desert southwest ridge retrograding northwest in the 9-14 day
range in the ensembles. If that is the case, a long lasting heat
wave could happen in mid August. DB
&&
.AVIATION...
06Z TAFS: The primary aviation concern through the 24hr TAF
period will be scattered showers and thunderstorms producing
gusty and erratic wind gusts. Under stronger storm cells,
frequent lightning and hail are also possible.
FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence
for largely VFR cigs through the TAF period. Low confidence for
individual timing of thunderstorms and associated wind gusts.
30-40% chance for local MVFR from reduced visibility under
rain/hail cores.
