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 Cheyenne, WY wrote its last area forecast discussion before this high wind warning went out at Feb 24, 10:40 AM MST, 2 hours 52 minutes earlier.

Area Forecast Discussion
National Weather Service Cheyenne WY
1040 AM MST Sat Feb 24 2018

.UPDATE...
Issued at 628 AM MST Sat Feb 24 2018

WYDOT webcams in the Arlington and Elk Mountain areas are starting
to show considerable blowing/drifting snow. It seems unlikely that
conditions will improve all that much today, as winds are expected
to remain strong and temperatures will remain below freezing. With
that in mind, we issued a Winter Weather Advisory valid until 6 PM
MST this evening. In addition, WYDOT observations already indicate
wind gusts in the 50-55 MPH range near ARL. Have upgraded the High
Wind Watch to a High Wind Warning starting at 15z.

The degree of blowing snow impacts across the remainder of the CWA
is uncertain at this time. The day shift will need to monitor this
closely in case additional Winter Weather Advisories are necessary
for the blowing snow threat.

&&

.SHORT TERM...(Today through Sunday night)
Issued at 217 AM MST Sat Feb 24 2018

Light snow will likely linger across portions of southeast Wyoming
and the western Nebraska Panhandle through mid-morning, before dry
westerly winds develop across much of the area behind the eastward
advancing surface trough. A few narrow, locally intense snow bands
were noted during the overnight hours, but in general impacts have
been low. Orographic snow showers will persist today, and probably
will through the weekend as well.

High winds are the main concern this weekend. A bit of uncertainty
with Arlington today, as CAG-CPR gradients are fairly modest at 50
to 60 meters and 700-800 mb flow is progged to peak at 45 knots or
less this afternoon. However, there may be enough subsidence for a
few gusts over 60 MPH. Will leave the High Wind Watch in place for
now. Bordeaux and the south Laramie Range look a bit better by 15z
today with pressure falls spreading over eastern Wyoming, into the
western Nebraska Panhandle. This should set up a respectable west-
east gradient over the Laramie Range which usually yields stronger
gusts for our eastern wind corridors. Decided to upgrade to a High
Wind Warning there. It may get very windy here in Cheyenne as well
with the majority of models showing good downward omega attempting
to sneak into the I-25 corridor by 18z. Main question right now is
whether last night's snow fall will influence mixing potential. Do
not think this will be the case as snow pack is limited. Soundings
from multiple models suggest excellent mixing with around 55 knots
on top of the mixed layer, and the MAV/MET are showing about 30-33
knot sustained winds for CYS. Our local probability guidance is on
the low side, but the statistical model likely is not capturing 55
knot flow just off the surface. Added central Laramie county & the
city of Cheyenne to the High Wind Warning.

A lull occurs tonight as low-level gradients weaken, the winds are
likely to increase again after 15z Sunday as a sub-1000 mb surface
low tracks along the International Border across MT and ND. A much
more favorable overall pattern for our wind corridors, so opted to
keep a High Wind Watch through Sunday. Removed the High Wind Watch
from the Saturday night time frame as strong winds appear unlikely
at that time.

.LONG TERM...(Monday through Friday)
Issued at 217 AM MST Sat Feb 24 2018

The 500mb height pattern will favor strong west-southwest flow on
Monday as a shortwave approaches the intermountain west. This
will favor strong winds along our high wind corridors Monday. Then
a weak frontal boundary is expected to sag into the northern
portion of our forecast area on Monday night which may trigger a
few snow showers in portions of the northern Laramie Range and
perhaps portions of Converse and Carbon counties.

The models are progging another shortwave to move through the
region on Wednesday. However, it does not look like this feature
will bring moisture with it, except for the higher terrain. It
will also be cooler day behind the front.

Thursday and Friday we should see a bit of a warm up as the upper
level ridge builds over the region, but it will be breezy over the
western half of the forecast area on Friday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Sunday morning)
Issued at 1040 AM MST Sat Feb 24 2018

Primary concerns for aviation operations will be strong winds and
mountain wave turbulence across much of southeast WY today.
Sustained winds of 30-35 kt with gusts 45-50 kt will occur at KCYS
through 00Z, with 25-30 kt sustained and gusts to 40 kt at KRWL and
KLAR. Blowing snow will also limit VIS to IFR w/ MVFR CIG at times
at KRWL this afternoon. Gusty W-NW winds of 30-40 kt will prevail
across most of the NE Panhandle this afternoon, with winds subsiding
around 00Z. Finally, snow showers will create low CIG/VIS over and
near the Snowy and Sierra Madre mountains through tonight.

&&

.FIRE WEATHER...
Issued at 217 AM MST Sat Feb 24 2018

No fire weather concerns. Despite periods of strong/gusty winds on
Saturday & Sunday, minimum RH values should remain well outside of
critical thresholds.
