An IsoDryT area was introduced for the Cascades from northern Oregon
through Washington. The preceding hot/dry conditions helped cure the
fuels quickly after last week`s rainfall leading to above normal to
daily record setting ERC values for portions of the IsoDryT area.
PWAT values less than 0.9" and continued high-cloud bases with dry
sub-cloud layers also help support this decision. A mix of wet/dry
storms are likely given the slow storm motions and slightly elevated
PWAT values, and there is some uncertainty regarding storm
development and coverage in the Washington Cascades.

Central Idaho into southwest Montana and northwest Wyoming was also
considered as there will likely be isolated to scattered mixed
wet/dry thunderstorms tomorrow. However, deeper monsoonal moisture
with widespread wetting rain is expected across these areas in the
following days that would help limit the ignition/spread potential.
Additionally, portions of northwest California may see a mix of
wet/dry thunderstorms even amid PWAT values of 1"+ and slow storm
motions.

.PREV DISCUSSION... /ISSUED 0154 AM CDT Sun Aug 24 2025/

...Synopsis...
Along the western periphery of an amplified large-scale ridge
extending from the Southwest/southern Rockies to the Northwest,
several midlevel disturbances will advance northward across parts of
the Great Basin/Sierra into the Northwest. Given well-established
monsoonal moisture across the region, scattered to numerous
thunderstorms are expected. While a mix of wet/dry thunderstorms are
possible (especially over parts of the Sierra into the Northwest),
generally 1.0+ inch PW and slow storm motions should favor mostly
wet storms capable of producing measurable rainfall. Nevertheless,
isolated lightning-induced ignitions will still be possible on the
peripheries of rain cores where fuels are receptive.
