What forecasters said that day

The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Pendleton, OR wrote its last area forecast discussion before this red flag warning went out at Jul 5, 8:57 AM PDT, 8 minutes earlier.

Area forecast discussion, Jul 5, 8:57 AM PDT, 8 minutes before
Area Forecast Discussion
National Weather Service Pendleton OR
857 AM PDT Wed Jul 5 2017

.UPDATE...Strong ridging over the four corners region will
continue to result in mainly dry and hot conditions across
the interior Pacific Northwest. Heat advisories will go into
effect this afternoon for most lowland locations, as highs
today will range from 98 to 103. 80s to lower 90s will prevail
across the mountains. There will be enough pooling of mid level
moisture and instability across the central OR cascades early
this evening for an isolated tstm or two. A very weak impulse
will move east tonight across the eastern OR mountains, but with
deep moisture limited and little/no elevated instability, have
left thunderstorms out of the forecast for now. Very mild 60s
will prevail for lows tonight across the lower elevations,
providing limited relief from the heat.

&&

.AVIATION...12Z TAFs...VFR conditions will occur over the next 24
hours. Mainly clear skies this morning. FEW-SCT cumulus developing
over the mountains in the afternoon and early evening with FEW-SCT
060-080. Winds will be 5-10kt morning, except at KDLS where winds
will increase to 10-15kt with gusts to 24kt in the afternoon.

&&

.FIRE WEATHER...The unseasonably hot temperatures, low relative
humidity, and unstable conditions the next several days will all
contribute to the potential for rapid fire spread and extreme fire
behavior. Fire Weather Watches have been upgraded to Red Flag
Warnings for Haines of 6 and relative humidity less than 15 pct
this afternoon through Thursday evening for Fire Zones 640, 642,
644 and 645 which covers the southern Blue Mountains, the John
Day Basin and Ochoco Highlands, the Crooked River National
Grasslands, the Prineville District, and the Wallowa District.
Thunderstorms, of course, are always a fire weather concern for
new starts. For this evening, the main area of concern will be in
the Deschutes National Forest but the lightning strikes should be
minimal without any highlights. Isolated thunderstorms on
Thursday in the eastern mountains are not expected to produce
abundant lightning, but highlights may be in order if any
disturbance comes across that may trigger more than a few
thunderstorms.

&&

.PREV DISCUSSION... /issued 435 AM PDT Wed Jul 5 2017/

SHORT TERM...Today through Friday night...A strong high pressure
ridge over the inland west and an upper trough off shore will keep a
hot south to southwest flow over the CWA through the rest of the
week. This will provide near record heat over the CWA through the
period. Temperatures will be about 15 to 20 degrees above normal CWA
wide. Maximum temperatures will range from 95 to 105 in the lower
elevations with mostly 80s to lower 90s in the mountains. This will
be the main concern over the forecast area through the next 3 days.
A heat advisory is in effect for today through Friday as a result
for most of the lower elevations. Temperatures at night will also
not cool off that much and this will add to the heat advisory
criteria being met. There will be just enough heat induced
instability and moisture on Thursday to induce mainly afternoon and
evening convection...thus a slight chance of thunderstorms will be
in the forecast for Thursday...which will be the hottest day this
week. Will highlight near record high temperatures in the zone
forecast. Any thunderstorms that do form will be isolated and mainly
over the eastern and northeast mountains. Took the thunderstorms out
of the previous forecast for Today and Friday due to a lack of
moisture though it will still be unstable, but very little moisture
to work with. This will create a moderate to high fire weather
Haines Index with very low humidities. A Fire Weather Watch is in
effect for today as a result. See the Fire Weather discussion below
for more details. Any thunderstorms on Thursday will also be helped
to be triggered by a weak wave in the southwest flow aloft that will
act as a trigger for convective development. Otherwise today and
Friday there will be some cumulus buildups but not expecting any
thunderstorms. The Fire Weather Watch may need to be extended or
upgraded to a warning, and possibly expanded, for Thursday as well
as today due to possible thunderstorms in the northeast mountain
fire weather zones. In any event the hot and dry weather will cause
fine fuels to cure faster over the next several days. There will be
a bit of a marine push of cooler air in the western public zones...
especially the eastern Columbia River Gorge for slightly cooler
temperatures. 88

LONG TERM...Saturday through Tuesday...Hot and dry conditions will
persist through the weekend into the coming work week due to a
stationary high pressure over the four corners. The flow pattern
around the high pressure continues to be from the southwest through
Saturday and the models do show some limited mid level monsoon
moisture and elevated instability over the mountains of northeast
Oregon for Saturday afternoon/evening. A trough moves into the region
Sunday thus suppressing the ridge and allowing a marine push to bring
a slightly cooler airmass into the forecast area on Sunday.  Polan
