PREV DISCUSSION... /issued 104 PM PDT Fri Jul 25 2025/

DISCUSSION...Satellite depicts clear conditions throughout the
region thanks to the trough pushing out of the area. Expecting
breezy winds to continue through the Gorge and Cascade Gaps, with
temperatures getting to the high 80s/low 90s. Not seeing concerns
for haze/smoke regarding the Burdoin Fire, but will always keep
monitoring for sudden changes in the forecast. Expecting the clear
conditions to persist through Saturday as the pattern begins to
shift into a more trough-esque pattern starting on Sunday. A
closed off low just offshore of Alaska will influence upper air
patterns to a more SW/SSW flow that will dominate the synoptic
side for the majority of the period. This will enable some
moisture to enter the region and introduce pop- up
showers/thunderstorms through next week. Storms are forecasted to
become more widespread as we go through the week as the SW flow
continues to build moisture, enabling more areas prone to
thunderstorms. As we get later into next week, the chances for
some potential thunderstorms increases (15-30% chance by Friday)
for parts of the Columbia Basin and throughout the majority of the
area.

At the same time, a ridge just to the east will shift towards the
west, building hotter air throughout the week leading to 40-60%
chances of triple digit temperatures throughout the Basin on
Tuesday and Wednesday. With confidence too low (5-15% chance) and
about a week out, we`re only at the monitoring stage to see if
this hazard progresses. NBM Heat Risk does blanket the region
with a risk of 2, with a couple of pockets of 3`s, although will
be curious to see how this changes with the recent trends on
Wednesday increasing. Given the intense day time heating occurring
with PoP chances increasing along with 250-550 J/KG of CAPE during
peak heating hours according to the NBM, went ahead and
introduced slight chances of thunder (15-24% chance) to all the
PoP areas throughout next week.

No current fire weather concerns throughout the weekend with the
winds around the Cascade Gaps being the only hazard being closely
monitored. Will need to pay attention with the expected
thunderstorms and heat building up into mid next week. For now,
red flag warnings are not being considered through Saturday.
