What forecasters said that day

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.

NWS Cheyenne, WY wrote its last area forecast discussion before this winter storm warning went out at Jan 20, 10:59 AM MST, 2 hours 14 minutes earlier.

Area forecast discussion, Jan 20, 10:59 AM MST, 2 hours 14 minutes before
Area Forecast Discussion
National Weather Service Cheyenne WY
1059 AM MST Sun Jan 20 2019

.SHORT TERM...(Today and tonight)
Issued at 354 AM MST Sun Jan 20 2019

A High Wind Warning is still in effect through early afternoon
along the wind-prone areas of southeast Wyoming. Otherwise,
conditions today will we mild and relatively calm across the
mountains and High Plains as a quick moving, dirty ridge passes
aloft. Isolated light snow showers are possible across the
northern portions of Converse and Niobrara Counties first thing
this morning, with a temporary drying trend this afternoon as the
ridge axis passes over the region. Temperatures will reach into
the 50s east of the Laramie Range and range between 30 and 40 to
the west.

.LONG TERM...(Monday through Saturday)
Issued at 354 AM MST Sun Jan 20 2019

A strong and deep upper level trough will drop out of the
northwest and move relatively quickly through the region this
Monday and Tuesday. Deep moisture, ample upper level dynamics and
surface forcing will make the passing of this trough a more note-
worthy event for the region. Precipitation will begin ahead of
the front, with showers spreading northwest to southeast as a
mixture of snow and rain, depending on the location and
temperature. Temperatures will range between 30 and 40 degrees
across the region, coming down a bit from Sunday's as mid to
upper level clouds stream in aloft. The cold front will move
through Monday afternoon and pass to the south and east by Monday
night. This front will carry two effects of note. One, as it will
be a strong front, winds will pick up significantly with its
passing and snow showers will increase in intensity, with the
potential for strong snow bands to form. Two, a deep, cold air
mass will follow in it's wake. By Tuesday, expect maximum
temperatures to be about 20 degrees colder than Monday's
- these lower temperatures will be near normal for this time of
year.

While areas along and east of the Laramie Range will generally
start off with rain, or a rain-snow mix on Monday, by Monday
night, all precipitation will change over to snow with 2 to 5
inches of snow accumulation possible across the region.
Additionally, a northerly low-level jet will form by midnight
Monday/TUesday and winds will pick up along and east of the
Laramie Range with gusts up to 45 mph possible. These winds will
continue through Tuesday morning as a surface low forms along the
Wyoming-Colorado border and wrap-around moisture streams in from
the north and east. Areas most prone to the strongest winds due to
this low pressure center will extend from Cheyenne to Alliance
and to the south and east.

Snow and blowing snow will be a concern across the region with low
visibilities causing difficulties in travel both on the Monday
evening commute and the Tuesday morning commute. A Winter Storm
Watch has been issued for most of southeast Wyoming and the
western Nebraska Panhandle for these reasons.

Snow showers taper off Tuesday with clearing in its wake as a
northwesterly flow aloft settles in over the region. While a few
shortwaves try to pass through the upper-level flow, no system
looks to bring widespread precipitation to the region for the
remainder of the week. Windy conditions and the continued
nuisance of blowing snow will be the main concerns for the week.
Wind highlights may need to be issued with future forecast
packages. Temperatures will remain within a few degrees of normal
Tuesday through Saturday. Windy conditions will cause wind chill
values to drop to about zero across the mountainous terrain.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday morning)
Issued at 1055 AM MST Sun Jan 20 2019

VFR conditions will prevail through this evening with lowering CIGS.
West to southwest winds will occasionally gust up to 30 kt across
southeast WY this afternoon, diminishing this evening, and increase
early Monday morning. Across the NE Panhandle, winds will be
variable to light southeasterly. HRRR/NAM model guidance trending
toward MVFR CIGS (BKN015-BKN025) for much of the NE Panhandle late
tonight. Deteriorating conditions will develop from west to east
after 15Z Monday.

&&

.FIRE WEATHER...
Issued at 354 AM MST Sun Jan 20 2019

Strong winds continue across the wind-prone areas of southeast
Wyoming today, but otherwise, today will be a mild and calm day
ahead of the incoming winter weather event approaching from
northwest to southeast Monday into Tuesday. This event will be
accompanied by significant snowfall and gusty winds. A relatively
cool pattern will follow keeping humidities out of critical
threshold values.
