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

Area forecast discussion, Nov 3, 10:24 PM MDT, 4 hours 6 minutes before
Area Forecast Discussion
National Weather Service Cheyenne WY
1024 PM MDT Fri Nov 3 2017
.UPDATE...
Issued at 452 PM MDT Fri Nov 3 2017
A few changes to the forecast. Looking at a prolonged snow event
for the Snowy and Sierra Madre Ranges this weekend into Monday.
Latest WPC snow forecast for these areas showing close to 2 feet
of snow through Monday. Going to be a big weekend out there for
Elk hunters, so there will be folks out there. Wanted to get the
heads up for them that it may not be too good for them over the
weekend. Went with a Winter Storm Watch.
Second...High winds at Arlington. They already hit a few times out
there today with Craig to Casper gradients at 43/38mtrs at
850/700mbs respectively. Latest high wind guidance showing these
gradients increasing tonight up to 50/49mtrs after 06Z. Decided to
issue a High Wind Warning for WY-110 as a result. Updates have
been sent.
&&
.SHORT TERM...(This evening through Saturday)
Issued at 222 PM MDT Fri Nov 3 2017
Low clouds have eroded over most of the CWA this afternoon but
still hanging on from about Alliance to Sidney. The erosion should
stop by evening then clouds likely will edge back westward
overnight as southerly winds return moisture. A little fog
possible over the southeast part of the Panhandle later tonight
into Saturday. Rest of the plains should see more of a westerly
component to the winds limiting cloud formation. Saturday looking
mainly dry and mild with even some max temps attaining 70 over
parts of the Panhandle. It will be rather windy especially over
southeast Wyoming by Saturday afternoon and could get close to
some high wind gusts out west given the favorable swly wind
direction. Overall threat looks low enough to preclude a watch at
this time however. Dry into Saturday afternoon then some showers
should begin increasing mainly over the higher mtns by late in the
day as increasing moisture rides up the west-facing slopes.
.LONG TERM...(Saturday night through Friday)
Issued at 222 PM MDT Fri Nov 3 2017
next cool front will push across the area Saturday night while a
shortwave swings across the northern plains. Rain and snow showers
should occur mainly over western and northern parts of the CWA
saturday night then be confined mostly to the mtns Sunday. More
unsettled weather should be over the CWA Sunday night into Tuesday
as the upper jet shifts over the region and several weak impulses
ride across in west-southwesterly upper flow. Still looking like
some decent total snowfall over the higher mtns by early Weds with
several shots of enhanced pcpn with the impulses. Over the plains
a stronger push of colder air should arrive late Monday with the
most widespread snow over the CWA Monday night and Tuesday. The
upper trough then passes by early Weds with drier and warmer
conditions in its wake to close out the week.
&&
.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1020 PM MDT Fri Nov 3 2017
Latest enhanced satellite imagery for low clouds showing a surge
of stratus to the west and northwest this evening. Very similar to
the HRRR guidance, so confidence is pretty high on the HRRR
output. Followed its guidance closely on the 06Z TAFs. Stratus
hangs in across the southern Panhandle...KSNY through 12Z before
shifting east. Also shows low clouds moving up the Platte River
Valley into KBFF, so have them coming down around 08Z. A very
windy day across southeast Wyoming Saturday with gusts close to
50kts at KLAR...KRWL and possibly KCYS.
&&
.FIRE WEATHER...
Issued at 222 PM MDT Fri Nov 3 2017
Overall concerns look to be low, especially from Sunday into next
week as a wetter and cooler weather pattern sets up over the
region. For Saturday it will be breezy to windy over much of the
area and there will be some elevated fire weather conditions over
extreme se Wy as afternoon humidities fall close to 20 per cent
and winds gust up to 35 mph near the Laramie Range.
