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 Tucson, AZ wrote its last area forecast discussion before this high wind warning went out at Apr 8, 3:03 PM MST, 12 hours 28 minutes earlier.

Area forecast discussion, Apr 8, 3:03 PM MST, 12 hours 28 minutes before
Area Forecast Discussion
National Weather Service Tucson AZ
303 PM MST Mon Apr 8 2019

.SYNOPSIS...Temperatures well above average to start the week with
the warmest readings of 2019 so far today and Tuesday. Increasing
winds the rest of the week with the strongest winds expected
Wednesday. Much cooler Wednesday and Wednesday night. A stronger
storm system should bring gusty winds Friday, followed by valley
rain and mountain snow late Friday into Saturday.

&&

.DISCUSSION...An unseasonable high amplitude pattern is going to
bring some extremes this week. A strong ridge anchored just off
the Baja California coast is pushing our temperatures to around 10
to 15 degrees above average today and tomorrow. Tucson hit the
first 90 of the year this afternoon, up several degrees compared
to yesterday at this time. We have room for several more degrees
of heating tomorrow, with middle 90s expected from Tucson westward
into the lower deserts (maybe even a touch higher but short of
100).

The gradient will start to tighten Tuesday as a strong trough digs
into the Great Basin bringing breezy to locally windy southwest to
west winds Tuesday afternoon. The strongest winds for our corner
of the state should be Wednesday with a High Wind Watch for much
of the area east of Tucson. NAEFS mean 700mb zonal wind is showing
near record climatological levels with 50 to 60 kts. As we
consider pushing the Watch to a Warning east of Tucson, we will
likely end up with an advisory in much of the rest of the area.
Please see the Fire Weather section below for additional details.

Solid cold air advection will drop temperatures 20+ degrees, and
the Thursday morning low may touch freezing in a few colder
valley locations east and south of Tucson (with best chances in
Sulphur Springs Valley in Cochise and southern Graham counties).

With strong and broad high pressure upstream over the Eastern
Pacific and downstream over the Eastern Seaboard, everything in
between will see large scale troughiness. As our Wednesday system
lifts into the central and northern Plains, another strong shot of
energy straight from British Columbia will have plenty of room to
dig all the way into Arizona. The GFS deterministic is starting
to catch on but is still further east and north than most
perturbations and its ensemble mean. We continue to have higher
confidence in other portions of North American ensembles and the
more consistent ECMWF with the NBM catching this nicely. That
means showers spreading in from the northwest Friday with best
chance for valley rain and mountain snow Friday night into
Saturday morning. Snow levels around 6500 feet for the best
dynamics/moisture couplet timing, with around 3 to 7 inches above
7000 feet.

Another chance at a few freezing overnight temperatures east of
Tucson over the weekend with temperatures remaining well below
average through at least Saturday.

&&

.AVIATION...Valid through 10/00Z.
FEW-SCT clouds above 20k ft AGL becoming BKN-OVC clouds above 20k ft
AGL by 09/06Z. SFC wind generally less than 12 kts thru 09/17Z, then
increasing SFC wind. Aft 09/17Z, SWLY/WLY SFC wind at 12-22 kts and
gusts to 20-30 kts, with the strongest wind east of KTUS in the
vicinity of KDUG, KALK and KSAD. Aviation discussion not updated for
TAF amendments.

&&

.FIRE WEATHER...Dry conditions will continue through Thursday, with
above normal daytime temperatures into Tuesday. A series of weather
systems will then pass north of the area, producing strong and gusty
winds Tuesday afternoon through Thursday. The windiest day occurs on
Wednesday. Critical fire weather conditions will likely be met on
Wednesday and possibly Thursday, especially east of Tucson. As such,
a Fire Weather Watch is in effect Wednesday and Thursday for eastern
portions of Fire Weather Zone 151 and all of Fire Weather Zone 152.
There will then be a chance of valley rain and mountain snow showers
starting on Friday and continuing through Saturday.
