Area Forecast Discussion
National Weather Service Pendleton OR
418 PM PDT Mon Jul 28 2025
.UPDATED AVIATION.
.AVIATION...00Z TAFs...VFR conditions prevail for all airport
sites. Thunderstorms are moving into the region and have a couple
of cells close to RDM/BDN. Went ahead and put in a PROB30 group
for RDM/BDN. Wasn't too confident to issue a line for the storms
since they don't appear to be widespread in that part of the
region. Most of the thunderstorm activity is situated in Eastern
Oregon from the John Day Valley eastwards. Some of the heavier
storms that pass through a site could temporarily put MVFR
conditions on that site, but nothing prolonged is expected. No
precip issues expected for other sites, but will keep monitoring
if the forecast changes.

.PREV DISCUSSION... /issued 200 PM PDT Mon Jul 28 2025/
DISCUSSION...Satellite and radar imagery shows mostly clear skies
across the region with convection activity developing over the
eastern mountains. With the S/SW flow aloft continuing along the
ridge, isolated to scattered thunderstorms will remain being our
popular threat through tomorrow during afternoon and evening hours
over central OR to the eastern mountains. This has led us to
issuing a Red Flag Warning for Tuesday from 1 PM to 11 PM for OR
ORZ697-698-700-705 and a Fire Weather Watch for ORZ696-699. Low
to moderate instability persists with MUCAPE values of 500-1000
J/Kg, effective shear at 20-30kts and anomalously high PWATs
(>0.70 inches). These parameters show that these storms' severity
may become slight to enhanced. For Wednesday, the SPC Outlook
shows general risk for thunderstorms across majority of our
region. Slight chance (<30%) of these storms may develop over
Deschutes County through Grant County before showers linger late
Wednesday evening into overnight.
Thunderstorms may become mainly dry with chances of wetting rain
(CWR) less than 0.10 inches, thanks to the upper ridge and thermal
trough. This will increase potential for abundant lightning to
impact any new or ongoing fires. Strong winds may also develop,
given the wind parameters show inverted-V sounding profiles, DCAPE
above 900, and steep lapse rates for dry microburst. These storms
will then gradually move across the eastern mountains and
portions of the Foothills of the Blues-OR by Friday night. We
should have a break over the weekend into Monday across most
locations, though the Wallowas may have a slight chance (<20%) of
thunderstorms around Monday afternoon. Convection activity should
weaken during overnight hours, leaving behind light showers. Fire
weather concerns will remain elevated for abundant
lightning/severe winds that could impact any fires in these
aforementioned locations.
Tomorrow and Wednesday will be our hottest days of this week with
high temperatures reaching from the high 90s to the triple digits.
Thursday onwards, temps will cool by a few degrees once a weak
system arrives. Winds will be breezy (15-25 mph) through Wednesday
before increasing to locally windy conditions around the Gorge and
Kittitas Valley Thursday afternoon into the weekend. Feaster/97
