What happened

The episode as NWS PDT wrote it up.

Narrative was pulled from InciWEB site. Lightning sparked the Lionshead Fire, which began August 16, 2020, in Lionshead Canyon on the Confederated Tribes of Warm Springs Reservation approximately 14 miles west of the Warm Springs community. An historic windstorm arrived in the area on Monday, September 7, rapidly spreading the fire west onto the Willamette, Deschutes and Mt. Hood National Forests. The Lionshead Fire has heavily impacted several communities in the Santiam drainage and Breitenbush area, including the loss of 264 resident homes in Detroit. Highly valued natural and cultural resources were also threatened.

Updated Aviation Discussion

Short Term...Tonight and Thursday...Few changes for tonight and
tomorrow's forecast, as high- amplitude ridging continues to
control our weather. High temps read lower in more elevated areas
Wednesday due to smoke layer aloft, particularly in Bend/Redmond
and the Blue Mountains, so adjusted highs downward for those
areas, and lows upward to compensate for any insulating effects of
the smoke. Haze may become more visible during the day Thursday,
otherwise quiet conditions expected with above-average highs in
the low to mid 80's, except 70's in the mountains.

PREV DISCUSSION... /issued 105 PM PDT Wed Sep 30 2020/

SHORT TERM...Tonight through Saturday...High pressure aloft will
remain parked over the region through the short term period. This
will keep warm and dry conditions, with light winds, over the
forecast area. The only fly in the ointment will be the smoke from
the California wildfires. If the smoke becomes too thick,
temperatures will be held down a few degrees during the day.
However, the smoke is fairly thin and is in an elevated layer over
the CWA at this time. Temperatures were only a degree or two
cooler than yesterday a couple of hours ago, but they have since
increased and become similar to yesterday. Am still expecting max
temperature readings in the mid 80s lower elevations and 70s in
the mountains. This is about 10-15 degrees above normal, and in
fact temperatures they will be near record highs for most of the
forecast area this afternoon and again on Thursday afternoon.
Winds will be light through the period, though there may be some
diurnal increases in the afternoons through the Cascade gaps,
passes and the eastern Columbia Gorge, especially on Friday as a
thermal trough deepens over the forecast area. 88

LONG TERM...Saturday night through Wednesday...A dry cold front
is expected to move across the region Saturday night and on
Sunday. It will bring some increase in mid and high clouds along
with some increase in wind, though the longer range models have
backed off a little on the winds. RH's will be high enough such
that the combination of wind and RH will not reach critical fire
weather conditions. High pressure aloft will then build back over
the region on Monday and will persist through the rest of the
extended forecast period, or at least through Wednesday.
Temperatures will cool off a few degrees from Sunday's cold front,
and then it will become warmer again by a few degrees on Tuesday
and Wednesday. However, will need to keep alert to how much smoke
is present or expected, which may affect the afternoon high
temperatures Tuesday and Wednesday. All indications are such that
it will remain at least 10 degrees above normal. After Sunday,
winds will become lighter again as well. 88

.AVIATION...06z TAFs...VFR conditions will continue as high pressure
aloft will keep skies clear and winds light. Smoke layer aloft from
California fires may cause haze to build throughout the day,
especially in OR, but no impacts to aviation expected.
