What happened

The episode as NWS PDT wrote it up.

The Substation Fire started on private land southeast of The Dalles, Oregon, on Tuesday, July 17, 2018 and grew quickly. Driven by strong winds, the fire moved more than 18 miles in the first burning period and crossed multiple agency jurisdictions. The fire covered an area that extended from 5 miles south of The Dalles, to 2 miles west of Moro, to the limits of Grass Valley, in both Wasco and Sherman counties in Oregon. One person died while operating a tractor cutting a fire line. Also a historic homestead was lost. Fire is being investigated as possible arson.

Area Forecast Discussion
National Weather Service Pendleton OR
157 PM PDT Tue Jul 17 2018

.SHORT TERM...Tonight through Friday...Satellite images show that
a few fair weather CU have developed over the mountains from Crook
to Wallowa Counties this afternoon. These clouds will dissipate
around sunset. Weak marine push and strong cross Cascade pressure
gradients have brought breezy to windy conditions in the Columbia
Basin and adjacent areas this afternoon. These winds will increase
more this evening. The strongest winds are expected in the Columbia
River Gorge and Kittitas Valley. Red Flag Warnings for wind and low
RHs have been issued for these areas.

A dry westerly flow aloft will persist over the region through the
short term period. This will keep mainly clear skies over eastern WA
and OR. Temperatures will cool a few degrees each day. Surface
gradients and westerly flow aloft will favor continued breezy
conditions each day, especially in the afternoon and evening.
Coonfield

.LONG TERM...Friday night through Tuesday...A fairly persistent dry
westerly flow will continue through the extended with no
precipitation expected. An upper level low moving eastward through
southwest Canada over the weekend will produce some breezy
conditions and slightly lower temperatures back to near normal for
this time of year. By first of the week, temperatures will again
begin to warm to slightly above normal.

&&

.AVIATION...00Z TAFs...VFR conditions are expected for the next 24
hours under clear skies. Winds of 10 to 20 mph with gusts to 25 to
30 mph into tonight dropping to 5 to 15 kts overnight. Winds will
increase again on Wednesday.

&&

.FIRE WEATHER...The Red Flag Warning was expanded to include all of
the Washington Lower Columbia Basin in effect until 8 PM Wednesday
evening--the same time as the other warnings in and around the
Columbia Basin down to Central Oregon. Winds are increasing with
gusts to 20-25 mph in many areas. The relative humidity generally
ranges from 10 to 20 percent. As winds increase and the humidity
decreases over the next several hours, the red flag conditions will
be met. Although winds will decrease overnight, there will be
lingering winds in the 10-20 mph range through early Wednesday
morning. Once again, gusts to 20-25 mph are likely again Wednesday
afternoon and evening and a few areas through the Columbia River
Gorge and Kittitas Valley will have gusts to 35 mph.  Unfortunately,
the wind and RH threat will continue through the end of the week. It
may be locally breezy on Thursday and breezy/windy on Friday.  Will
address the upcoming winds on Friday after the expiration of the
current warnings.  Wister
