The episode as NWS CYS wrote it up.
Widespread light to moderate snow developed across the western Nebraska Panhandle during the evening hours on November 28th, persisting through the morning of the 29th. Total snowfall accumulations of 3 to 6 inches were common, with local amounts of 6-7 inches observed along sections of the Cheyenne Ridge in Banner county, where narrow heavier bands resulted in periods of snowfall rates in excess of 1 inch per hour late in the evening on the 28th into early on the 29th.

Area Forecast Discussion
National Weather Service Cheyenne WY
442 PM MST Mon Nov 28 2022
.SHORT TERM...(This evening through Tuesday Night)
Issued at 201 PM MST Mon Nov 28 2022
The main concern with this portion of the forecast is where the
snowfall banding will be setting up this evening and overnight.
Latest radar loop was showing the frontal boundary just about 10
miles away from Cheyenne and should pass through the area during
the next hour or so. Radar loop and web cams were showing
snowfall becoming more widespread along and north of a Chugwater
to Torrington line and west of I-25. Latest satellite derived
winds were showing strong jet energy across northern Wyoming with
southeast Wyoming in the right entrance region of the upper level
jet streak. The HRRR/NAMNest trends were also showing some
700-600mb frontogenetical forcing developing over the Pine Ridge
region late this afternoon into this evening. Latest radar loop
from Rapid City was showing some evidence of this banding south
of the Black Hills where a convergence zone appears to be
forming in response to the northerly flow. We did bump up snow
amounts along the Pine Ridge tonight to reflect this potential.
The rest of the area, the models are showing good quasi-
geostrophic forcing overnight which will favor light to moderate
snowfall across the region. There is still considerable
uncertainty on where the next frontogenetical band will form.
With the exception of the HRRR, several of the HiRes models are
showing the next frontogenetical band forming after midnight
north of the Cheyenne Ridge. We tended to lean towards the
previous forecast in keeping the highest totals between Wheatland
and Horse Creek. With that in mind we went ahead and upgraded
forecast zones 106, 116 and 117 to a Winter Storm Warning since it
covers I-25 and I-80.
The models are showing things moving out a little quicker than
previous runs. Therefore, we have trended that direction with most
of the snow clearing out by Tuesday afternoon. High pressure will
then settle into areas east of the I-25 on Tuesday night which
will allow for strong radiational cooling due to the fresh
snowpack. Could be flirting with some Wind Chill Advisories in
some locations especially in the higher terrain with the
possibility of blowing snow developing west of I-25 due to strong
jet energy building into the area under a weak upper level ridge.
.LONG TERM...(Wednesday through Monday)
Issued at 201 PM MST Mon Nov 28 2022
No major changes to the long term forecast, as upper level ridging
continues to move eastward from the western seaboard and large scale
subsidence tracks into the CWA. Warming trends are expected under
this pattern throughout the day on Wednesday, with 700mb
temperatures increasing from -19C to -5C by 18z. Daytime highs will
rebound into the high-20s, and even low-30s, for most areas east of
I-25 on Wednesday and climbing towards seasonal averages by
Thursday. Despite the much more mild conditions expected from the
warming trends, winds are likely to increase from mid to late week,
with a series of minor disturbances propagating within the flow. In-
house model guidance has consistently increased probabilities
towards high winds Thursday through Friday and the NBM v4.1
Probability of Exceeding 41 knots echoing this guidance across the
the wind prone areas along the I-25 and I-80 corridors, and along
the Laramie Range, with seeing high likelihoods of reaching speeds
greater than 41 knots across those zones. As a result, went ahead
and started trending those wind speeds upwards.
Next chance for precipitation is progged for early Friday, mainly
across the higher terrain, with long range models picking up on a
shortwave trough pushing from the Pacific Northwest eastward
across the High Plains. Models are trying to nudge precipitation
upward mainly west of I-25 from this system. However, confidence
remains low at this time with the shortwave appearing a bit too
far to the north to provide any measurable precipitation outside
of the mountain zones.

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 436 PM MST Mon Nov 28 2022
Aviation conditions will continue to deteriorate this evening as
snow spreads into all terminals. The main takeaway is that snow
showers of varying intensity can be expected to begin at all
terminals in the next few hours, and continue through Tuesday
morning. Bands of locally heavier snowfall are likely to develop,
but the location is still uncertain. Addressed this possibility
with TEMPO groups for moderate to heavy snow reducing visibility
to 1/4 to 1/2 mile at times. The TAF shows expected general
trends, but expect to see fluctuating CIGs and VIS as snowfall
intensity will not be consistent. KLAR is a particularly tricky
forecast, where a switch to easterly winds later tonight could
significantly improve flight conditions, but the timing of this is
uncertain.
Low clouds and snow will gradually clear out Tuesday morning into
the early afternoon. Expect increasing winds behind, with BLSN
possible at KRWL towards the end of the TAF period.
