What forecasters said that day

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

NWS Flagstaff, AZ wrote its last area forecast discussion before this high wind warning went out at Apr 14, 9:04 PM MST, 7 hours 15 minutes earlier.

Area forecast discussion, Apr 14, 9:04 PM MST, 7 hours 15 minutes before
Area Forecast Discussion
National Weather Service Flagstaff AZ
904 PM MST Sat Apr 14 2018

.SYNOPSIS...Warmer and breezy weather is expected on Sunday, with
strong winds returning on Monday, as a cold front moves into the
state. Cooler conditions will follow this front on Tuesday, with a
warming trend for Wednesday. Strong winds then make another
appearance later next week, on Thursday and Friday.

&&

.DISCUSSION...North-northeast winds have continued to decrease
this evening with generally light winds anticipated overnight. A
ridge of high pressure will shift across the area through the day
Sunday in advance of a potent cold front. This front will cross
the region later Monday into Tuesday leading to another round of
strong southwesterly winds and critical fire weather conditions.
The Fire Weather Watch remains in place for northern Arizona from
Monday morning through Monday evening. Wind advisories/high wind
products will likely be issued with the next forecast package to
highlight the wind threat for the region. Models continue to
indicate another threat for strong winds later next week in the
Thursday-Friday time frame.

&&

.PREV DISCUSSION /255 PM MST/...North through northeast winds are
slowly decreasing this afternoon as upper level support fades due
to a ridge building in from the west. This ridge will last
through Sunday, before breaking down dramatically on Monday and
Tuesday.

We cannot break down a ridge that fast without some wind.
Southwest winds increase as early as Sunday, with strong winds
likely again on Monday. This is all ahead of a cold front Monday
night and Tuesday. This on and off pattern will repeat at least
one more time later next week, with a strong cold front due next
Thursday and Friday.

Moisture is severely limited with both systems, the low later in
the week has the best shot for some shower development. Both
events will likely generate widespread Red Flag conditions and a
watch is out for Monday. Public headlines are not out yet, but
most areas will probably see Wind Advisory conditions on Monday,
with a few pockets of gusts from 55 to 60 mph.

&&

.AVIATION...For the 06Z package...VFR conditions will prevail over
the next 24 hours, with increasing high clouds on Sunday.
Southwesterly breezes will develop after 17Z Sunday. Aviation
discussion not updated for TAF amendments.

&&

.FIRE WEATHER...Warmer weather and breezy southwest winds will
develop Sunday. Strong southwest wind is likely Monday, which is
expected to lead to widespread critical fire weather conditions into
Monday evening.

Tuesday through Thursday...Breezy west or northwest winds are
forecast for Tuesday, becoming lighter on Wednesday. A deep trough
moves into the fire district Thursday bringing more strong and gusty
winds, along with a chance for precipitation.

&&

.FGZ WATCHES/WARNINGS/ADVISORIES...Fire Weather Watch from Monday
morning through Monday evening FOR AZZ104>118-137>140.
