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.

.DISCUSSION...04/12Z NAM in.

A hot and dry forecast remains in place through next Friday,
though it may be a tad cooler toward the end of next week.

Strong high pressure currently centered over Nevada is bringing
south to southwest flow aloft over the area. This has brought up a
lot of wildfire smoke from the California fires. The flow aloft
will become more southwesterly with time as the high drifts east,
and this will act to slowly shunt the smoke farther east with
time.

There won't be a lot of change through the weekend. The main
concern is fire weather, as daytime humidities will be very low
with some gusty winds in the valleys. At night, the main concern
is low level easterly flow over the ridges, leading to poor to
moderate humidity recoveries. Red Flag Warnings are in effect at
this time, see PDXRFWMFR for details.

Another concern is the heat, and a Heat Advisory remain in effect
into Sunday. 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.

.AVIATION...For the 04/12Z TAFs...VFR will prevail away from the
coast through Friday.  Along the coast, IFR and MVFR ceilings linger
for most of the morning. Those lower ceilings are expected to burn
off over most of the coast, yet stay around OTH into the day. More
low MVFR ceilings will impact the coast again on Friday night.

Away from the coast,  smoke will also linger west of the Cascades
and in northern California.  Look for lower VFR visibilities near
the Red Salmon fire and in some of the valleys west of the Cascades
this morning.  Visibilities will improve into the day, except
near the Red Salmon Fire.

pressure will persist into Saturday morning with areas of fog,
diminishing seas, and weak southerly winds. North winds then return

steep to very steep in the outer waters south of Cape Blanco.

We're expecting north winds to begin to increase Saturday evening
with small craft conditions covering the outer waters.  Winds will
continue into increase into Sunday with gale force winds possible
Sunday afternoon and evening in the outer waters south of Gold
Beach. Seas will become hazardous and increase up to 10 - 14 feet
south of Cape Blanco Sunday night.
