.UPDATED AVIATION DISCUSSION...


.AVIATION...12Z TAFs...VFR conditions will persist through the
entire period. Winds will remain mostly at or below 10 kts, with
the exception of DLS, which will increase to 12-15 kts with gusts
between 20-25 kts after 20Z. There`s a low chance (<20%) for
thunderstorms at RDM and BDN between 21Z-03Z, however chances
continue to remain too low to include in the TAF. If these do
occur and impact the terminals, occasional strong winds and heavy
downpours could reduce visibility to MVFR or lower.

PREV DISCUSSION... /issued 157 PM PDT Sat Jul 26 2025/

DISCUSSION...Satellite displays clear to fair skies for the
region. Winds are generally breezy. with the strongest winds
located near the Mountain Gaps near the Gorge. Winds will top at
25-30mph before they decrease to light and variable in the
overnight hours. Strongest winds will be today, with a weakening
trend as we go through the rest of the weekend into early next
week. A ridge over the central southern parts of the CONUS will
drift westward through the coming days, allowing for temperatures
to start a warm trend going through mid next week. NBM models
currently show highs entering the triple digits (50-70% chance)
Tuesday and Wednesday, with Wednesday looking to be the hotter
day. Although areas that will experience triple digits doesn`t
appear to be widespread at this moment, many areas across the
region are likely (80-90% chance) to experience mid to high 90s; a
10-15 degree above the normal for this time of year.

Pattern will remain quiet and dry until the closed off low
situated in Alaska moves further offshore. This southward move in
the low will shift our winds aloft in a more SW/SSW flow, allowing
for moisture to enter the region and adds fuel for thunderstorm
chances going into next week. This SW/SSW flow will linger through
mid next week, allowing for thunderstorm chances (15-25%) to
spread more areal coverage going through Thursday. The first round
of thunderstorms in the area will be tomorrow across the Eastern
Mountains and parts of the Southern Blues into the early afternoon
hours (15-25% chance). Coverage spreads into Central Oregon
heading into the late afternoon/early evening hours of Sunday.
Thunderstorms Monday and Tuesday will reflect a similar situation,
but more focused on Central OR and Southern Blues

Our biggest concerns for widespread thunderstorms through the
region (including the Basin and Kittitas Valley) is Wednesday and
Thursday as deeper moisture builds into the region from the low
system moving eastward. This will draw some fire concerns as
lightning could be potent in a strong developing thunderstorm.
Given that, we will keep monitoring for any necessary fire
highlights going into next week as storms become more widespread
through the week.
