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 Nov 15, 10:22 AM MST, 1 hour 43 minutes earlier.

Area forecast discussion, Nov 15, 10:22 AM MST, 1 hour 43 minutes before
Area Forecast Discussion
National Weather Service Cheyenne WY
1022 AM MST Thu Nov 15 2018

.SHORT TERM...(Today through Saturday morning)
Issued at 245 AM MST Thu Nov 15 2018

Mild temperatures have been the story today and tonight as
observations continue to show a mild air mass hanging around. as
of 09z CYS reported temperatures in the lower 40s, several degrees
above normal. This was likely due in part to some turbulent mixing
from stronger westerly winds aloft. Winds should relax later
tonight as clear skies will help temperatures cool into the mid to
lower 30s for most.

Thursday will be another mild and mostly clear day. 700 mb
temperatures are a bit cooler than yesterday as an upper level
front starts to move through. This should keep high temperatures a
bit lower than yesterday which over achieved by a few degrees.
Expect middle to lower 50s for the foot hills and in and around
cheyenne with upper 50s likely for the plains of the Nebraska
Panhandle. Weather wise things should be mostly clear with a few
gusty winds from the increasing westerly jet aloft.

Things start to get interesting Friday morning as an area of low
pressure will move southeast over the Central Plains. CAG to CPR
850mb gradients will start to approach 60 meters which should ramp
the winds up for some of the Gap Wind prone areas including
Arlington and Bordeaux. Currently expecting 30 to 40 mph with
gusts to 50 mph early morning Friday before the inversion lifts
and the gradient relaxes a bit (see the most recent SPS). This
will be watched closely should High Wind Warnings be needed,
however, at the current time it looks like winds will stay below
criteria.

The cold front swinging down behind the low should bring a shift
to northeasterly Friday afternoon and evening. Rapid cooling is
expected behind the front as temperatures plunge into the upper
20s. A quick transition from rain to snow is likely as strong low
level cold advection and upslope develop in the wake of the
front. Strong dynamic lift characterized by height falls of 2 to
3 DAM ahead of the elongated trough should bring widespread
snowfall to southern Wyoming and the Nebraska Panhandle late
Friday night. Model soundings have continued to indicate a
saturated dendritic growth layer with significant vertical motion
and upslope flow. All signs point to a fairly stout snow event
shaping up across the area. The one caveat remains the progressive
nature of the system which should be gone by early evening
Saturday. Winter Storm Watches have gone up for Friday Afternoon
until Saturday evening in anticipation of travel impacts from this
storm. Models are in reasonable agreement on QPF and snowfall.
One exception is the NAM which has shown much lower amounts over
southeastern Wyoming. Ensemble guidance from the SREF shows
clustering of the NAM members in the lower amounts generally 1 to
2 inches while the rest of the guidance is higher. The GFS is the
most bullish with over 6 inches on the 00z runs. This seems a
touch high, but a good mix of the models suggests snowfall amounts
of 2 to 5 inches in the plains and foothills, with 5 to 10 inches
over the Laramie Range are expected from this storm.

.LONG TERM...(Saturday night through Wednesday)
Issued at 245 AM MST Thu Nov 15 2018

Medium range models/ensembles are in good agreement progging the
passage of the mid/upper level trough Saturday night. Snow will
end from north to south at that time. Temperatures by Sunday
morning will be quite cold with single digits to lower teens. A
dry west to northwest flow aloft will prevail with temperatures
moderating to above normal by mid-week.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1015 AM MST Thu Nov 15 2018

VFR conditions expected next 24 hours with gusty west to northwest
winds. Conditions expected to change late Friday afternoon as a
cold front moves into the area from the northwest. Widespread snow
and upsloping winds Friday night into Saturday expected for most
airports in southeast Wyoming and Nebraska Panhandle.

&&

.FIRE WEATHER...
Issued at 230 AM MST Thu Nov 15 2018

Fire Weather conditions are unlikely through this period as wet
and cold weather conditions will develop late Friday and continue
through Sunday. Significant snowfall should hamper any fire
potential through the period.
