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 Medford, OR wrote its last area forecast discussion before this red flag warning went out at Sep 6, 4:51 AM PDT, 50 minutes earlier.

Area forecast discussion, Sep 6, 4:51 AM PDT, 50 minutes before
Area Forecast Discussion
National Weather Service Medford OR
451 AM PDT Sun Sep 6 2020

.DISCUSSION...The stubbern Rex block pattern, which is a upper
high positioned to the north of a closed low, will transtion to an
Omega block pattern, which is a ridge that straddles a low on
either side like the greek letter Omega, over the next several
days. As evidenced by the continued hot and dry weather over the
past many days, and remaining through the next week, both of
these patterns are very stubborn and generally require a good
"kicker" to dislodge. However, what will happen during the
transition from the one stubborn pattern to the next stubborn
pattern will bring a potentially dangerous weather situation to
the region Monday into Tuesday. A short wave spinning around a
deep upper low north of Hudson Bay will bring a deepening upper
trough down into the great basin Monday.

Before this happens heights rise over the area, and with weak
offshore flow transitioning to a more northerly flow west of the
Cascades this afternoon, temperatures will be roughly 4 to 7
degrees warmer today compared to yesterday. A Heat Advisory
remains in effect through Monday. While the daytime highs are very
hot, the nights are getting longer and this allows more overnight
cooling, allowing some respite from the heat. See PDXNPWMFR for
more details.

Winds at 10,000 ft become almost due west over most
of the region today, with winds at 18,000 feet and down to ridge
top level are southerly south of the forecast area feeding into
the region today. The smoke feeding into northern California will
be pushed to the northeast and then east as it moves in today.
This upper flow then becomes northwesterly Sunday evening, and
then northerly by Monday afternoon, pushing the bulk of the smoke
from california out of the region.

As the upper trough deepens to to the east of us by Monday night
the winds closer to the surface first becomes northeasterly, with
gusty winds east of the Cascades Monday evening. As the upper
trough deepens further the winds increase and becomes easterly
across the entire forecast area. A very dry air mass remains over
the region Tuesday with east winds increasing overnight into the
day. Ridage level winds are indicating to have gusts in the 30 to
40 mph range from the east on the coastal ranges.

With these very dry and very windy conditions Red Flag warnings
are in effect From Monday through Tuesday over the entire forecast
area, see fire weather discussion below for more details.
precautions should be taken for this period, such as no burning of
any kind, don't park in tall dry grass, no power tools such as
lawn mowers in dry vegetation, etc. If there is debris in your
gutters, or dry flammable material anywhere near your house, today
is the day to clear that out if you haven't already.

The Upper trough deepens and closes over the four corners region
by Wednesday morning, bringing a text book Omega block pattern
with winds decreasing rapidly into Wednesday morning. This pattern
then remains into next weekend.

&&

.AVIATION...For the 06/12Z TAFs...Smoke will remain thick from
northern California into Jackson, Klamath, and Lake Counties and
eastward through the evening. This will continue to reduce
visibilities down to MVFR over most of northern California and
locally around southern Klamath County, possibly IFR in western
Siskiyou County near the Red Salmon fire.

Also, IFR is expected late tonight into early Sunday morning over
the coastal waters and near shore north of Cape Blanco. Elsewhere,
VFR with clear skies will continue into Sunday evening.

&&

.MARINE...Updated 300 AM PDT Saturday 5 September 2020....High and
very steep seas will occur in the outer waters south of Bandon this
afternoon. These very steep seas will be around 9 to 12 feet beyond
30 nm away from shore.  Within 10 nm from shore, seas will be around
5 to 7 feet. Localized gusts nearing gale strength are expected this
afternoon and evening from near Cape Blanco southwestward to 5 to 30
nm offshore from Gold Beach.

North Winds will decrease Monday morning with steep seas lowering to
7-9 feet north of Cape Blanco and near shore south of Cape Blanco.
However, seas will remain around 9 to 11 feet and very steep in the
southern outer waters.

The thermal trough will move offshore Monday night into Tuesday.
This will start a trend of diminishing seas but bring east winds to
areas north of Cape Blanco. The mix of fresh swell and east winds
will create a mixed and chaotic sea state beyond 30 nm away from
shore Tuesday.  The thermal trough will remain offshore and weaken
Wednesday with weaker winds and lower seas likely for the remainder
of the week.

&&

.FIRE WEATHER...Updated 200 PM PDT Saturday 5 September 2020...Two
main concerns exist in the forecast period and they are all for
gusty winds and low relative humidity. The first concern will be
into this evening in portions of Fire Zones 285, 622, 624 and 625.
Second is expected to be Monday afternoon east of the Cascades and
Monday night into at least Tuesday evening from the Cascades west,
although concerns could still continue east of the Cascades. Details
on all of this follow below.

The combination of stronger winds aloft (which could mix down near
or at the surface and tighter pressure gradient will be the main
contributing factors for gusty winds into this evening. Because
relative humidities will be low (with some areas east of the
Cascades flirting with single digit values), it's not going to take
much wind for conditions to reach critical levels. Thus a Red Flag
Warning remains in effect into this evening.

Of note, a Red Flag Warning remains in effect for a Haines 6 for the
Grizzly Creek Fire just northeast of Howard Prairie Lake. Gusty
breezes are possible above the tree line late this afternoon and
evening, but were not expecting them to be strong.

All the ingredients are there for a significant east wind event
starting Monday night and lasting into at least Tuesday evening. The
operational models and most, if not all ensemble members are in good
agreement showing an upper level trough (inside slider) moving south
into northeast Oregon Monday with a dry cold front moving into the
area. This pattern is expected to result in gusty north to northwest
winds and low relative humidity Monday afternoon east of the
Cascades, followed by steady moderate to strong east winds across
the entire area Monday night into Tuesday night. Winds will be
strongest over the higher terrain along the Cascades and west side.
Models all show a very tight pressure gradient along the Cascades
which us usually a recipe for moderate to strong winds. Would not be
surprised if wind gusts exceed 40 mph for the mid slopes, ridges and
exposed areas along the Cascades and 30-35 mph in the higher terrain
and exposed areas west of the Cascades Monday night into Tuesday
morning.

Temperatures would remain quite hot west of the Cascades, but would
trend cooler on the East Side. However, humidities would suffer
greatly, dropping to minimums in the single digits to low teens
across nearly the entire area, and recoveries becoming poor for a
significant portions of the region. The timing of when we expect
critical conditions to develop have not changed much, so the start
times of the Fire Weather Watch east of the Cascades and elsewhere
remain the same. However there's increasing concern for moderate to
strong winds over the mid slopes and ridges in Fire Zone 619 along
with low relative humidities, so they will be added to the already
existing Fire Weather Watch.

To recap, a Fire Weather Watch remains in effect for east of the
Cascades starting Monday afternoon into Monday evening, then Monday
evening into Tuesday evening along and west of the Cascades. The
exception is Fire Weather Zones 615, and 618, mainly because
confidence is not high enough relative humidities will be low enough
in Fire Zone 615 and winds may not be strong enough in 618. However
this could change, so stay tuned for the latest updates on this.
Details on all the Red Flag Warning and Fire Weather Watches can be
found at RFWMFR.

Some of the models suggest the gradient along the Cascades may relax
later Tuesday evening overnight Tuesday, so we could see east winds
beginning to diminish along and west of the Cascades during this time
which is why we have the end time of the Fire Weather Watch at 10 pm
pdt. Since this is still a few days out, the timing on this could
change, so stay tuned for the latest updates. -Petrucelli
