What forecasters said that day

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

NWS El Paso, TX wrote its last area forecast discussion before this wind advisory went out at Sep 26, 11:56 PM MDT, 3 hours 58 minutes earlier.

Area forecast discussion, Sep 26, 11:56 PM MDT, 3 hours 58 minutes before
Area Forecast Discussion
National Weather Service El Paso TX/Santa Teresa NM
1156 PM MDT Sat Sep 26 2020

.AVIATION...06Z TAF CYCLE
Clear skies through the perioid. West to NW winds will diminish to
around 6-12 knots before dawn, but will remain a little gusty at
ELP due to downsloping (few gusts 20-24 knots). An approaching
surface trough will reach the Rio Grande during the afternoon,
with a tightening pressure gradient bringing a return to breezy
NW winds in the 15 to 20 knot range, and gusts 22 to 28 knots.
The stronger winds will generally be west of the Rio Grande.

&&

.PREV DISCUSSION...337 PM MDT Sat Sep 26 2020...

.SYNOPSIS...
One more day of breezy winds and near-record hot temperatures on
Sunday, before the weather pattern changes Sunday night. A strong
backdoor cold front will move through the Borderland on early
Monday morning, bringing windy conditions behind the cold front,
with the potential of areas of blowing dust. Monday will be
dramatically cooler, with temperatures roughly 20 degrees cooler
than Sunday. Low temperatures Tuesday morning may reach below
freezing on the highest peaks of the Sacramento Mountains. The
rest of the week, expect gradually rising temperatures, with dry
conditions continuing.

&&

.DISCUSSION...
.SHORT TERM...Tonight and Sunday...

Tonight, high pressure over the southwest persists, and temperatures
remain around normal tonight. Winds should calm down a couple hours
after sunset, but isolated gusts could occur as a surface trough
around northeast NM holds over night. The environment remains dry,
so no precipitation tonight and through the short term period.

A stronger upper level trough in the northern plains begins to move
south Sunday morning. The upper level high pressure over the area
gets squeezed west to AZ. With northwest flow aloft (and at the
surface), temperatures should drop a couple of degrees Sunday. High
pressure at the surface sets up over the central AZ/NM border. With
the surface trough to our east, a nice pressure gradient sets up
over the area. Models are hinting at the strongest northwest winds
setting up around the AZ/NM border by Grant county, continuing
through the southern areas on Grant county and into Luna county, and
exiting our area by the US/MX border by western Dona Ana county.
Some ideal fire weather conditions could set up in this area
mentioned, as well as wide spread blowing dust especially around the
Lordsburg Playa.

&&

.LONG TERM...Sunday night through Saturday...
What you need to know:
-Strong winds moving in late Sunday in Monday morning, especially
 for Hudspeth and Otero counties and west slopes of area
 mountains;
-Much cooler temperatures on Monday (~20F+ difference from
 Sunday);
-Highest elevations in the Sacramento Mountains could drop below
 32F on Tuesday morning;
-Dry conditions continue.

Sunday night, high pressure sets up over the western U.S., with a
high amplitude upper trough dropping into the central U.S.,
placing the Borderland in dry, northwest flow. This will push a
surface high south across the western US, bringing a strong, and
fast-moving, backdoor coldfront into the Borderland overnight
Sunday. Medium range models show the front reaching the
Sacramento Mountains by roughly midnight, pushing through the CWA
by sunrise. An impressive 15mb surface pressure gradient rise
behind this front will make for a windy start to the work week for
some areas. Models indicate that our southern half of the CWA,
and west slopes, will take the brunt of the wind. Therefore,
expect sustained N/NE winds 25-35 mph across Otero, Hudspeth and
eastern El Paso counties starting after (roughly) 3am Monday
morning; stronger gusts to 45-50 mph+ possible, especially on the
aforementioned west slopes. The strongest winds should last
through (roughly) 10 am in these areas. If model trends continue,
expect (at least) a Wind Advisory to be issued for these areas.
By mid-morning, the strongest winds shift ("only" 15-25 mph;
gusts to 35+ mph at this time), setting up south of the I-10
corridor. Wind will continue to gradually decrease through the
late afternoon and evening. In addition, given how dry the soils
are, blowing dust will likely be a problem throughout the day on
Monday. I've placed a mention on blowing dust in the forecast for
Dona Ana, El Paso and Hudspeth counties, but coverage may be
expanded by future shifts.

Monday also promises to be dramatically cooler, with strong H7
cold air advection through the day, allowing highs to top out
15-25F cooler than Sunday. This means mid to upper 70s in the
lowlands. With cooler highs, and lack of WAA, come cooler lows for
Tuesday morning. We will be watching out for areas in the highest
peaks of the Sacramento Mountains to drop below freezing by
Tuesday morning. This could warrant a Freeze Warning by future
shifts. Otherwise, most of the lowlands will be in the mid to
upper 40s.

From Tuesday through the rest of the long term, a synoptic PNA
pattern sets up over the CONUS, with upper-level high pressure slowly
sliding into the region through the week. This will cause a
gradual warm up to near seasonal average temperatures through the
week, with zero precipitation chances through the period.

.FIRE WEATHER...
A surface trough over northeastern NM will tighten the surface
gradient over the Sacramento Mtns this afternoon, leading to
slightly windy conditions. Combined with the persistent dry air, RF
conditions will be met this afternoon in FWZone 113, especially in
the northern areas. Winds should calm down around sunset. The
surface gradient will persist through the night, so isolated wind
gusts can exist in zone 113. However, max RH recoveries will be in
the 40 to 50% range tonight.

Tomorrow, Sunday, surface high pressure sets up over the central
AZ/NM border. The surface trough over northeastern NM starts to move
southeast. This set up will move the focus of faster winds to
FWZones 111, the southwestern part of 110, and a smaller part of 112
in the southwestern corner. Winds will increase in the afternoon
hours to 15 to 25mph with gusts up to 30mph. Min RH values remain
around 10 to 15%. A Red Flag is issued for Sunday afternoon for
FWZones 111.

A very strong trough begins to move south late Sunday night. A
coldfront will move into the area early Monday morning, cooling down
temperatures dramatically and bringing wind conditions to the
eastern zones. No RF will be needed for Monday, as temperatures will
stay low enough to keep min RH values up. However, a freeze warning
will be likely for Tuesday night in the Sacramento Mountains.

After Monday, the upper level trough moves to the east and a high
tries to rebuild to our west; giving us northwesterly flow aloft. So
temperatures are slow to warm back up to normal, moisture stays out
of the area (taking Min RH values back down to 15 - 20%), but winds
remain calm. These conditions will last through next week and into
next weekend.
