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 12, 10:38 PM MST, 3 hours 42 minutes earlier. Its key messages:
- Strong winds across the wind prone corridors and areas along and west of the Laramie Range in southeast Wyoming today. High Wind Warnings have been issued.
- Snow squalls along the Interstate 25 and 80 corridor possible today, primarily this afternoon.
- Mountain snow continues, with high-elevation travel likely to remain very difficult or impossible for some time. Winter Storm Warnings remain in effect for the Snowy and Sierra Madre ranges through Saturday AM. Another heavy snow event taking shape for Sunday/Monday. A Winter Storm Watch is in effect for the Snowy and Sierra Madre Ranges.
- Extremely cold temperatures and wind chill values are expected across much of SE Wyoming and the Nebraska Panhandle this weekend. Wind Chill Warnings have been issued for portions of southeast Wyoming and the entire Nebraska Panhandle.

.UPDATE...
Issued at 604 PM MST Fri Jan 12 2024
Forecast remains largely on track this evening as the arctic
front passed through Cheyenne around 22Z this afternoon. Snow
squall concerns remain this evening as the arctic front pushes
across the I-25 corridor. Snow showers continue east of the
Laramie Range with a heavier band currently just north of
Cheyenne, stretching from 10 miles northeast of Laramie to
Kimball County in western Nebraska. Snow showers expected to
remain in the area throughout the evening hours. Additionally,
allowed most of the High Wind Warning to expire as winds dropped
below criteria around 5PM today. Did extend the High Wind
Warning until 07Z for the Arlington zone due to winds remaining
at high wind criteria and the front remaining stalled across
northern Carbon County. Winds will decrease quickly once the
front moves through.
&&
.SHORT TERM /THROUGH SUNDAY NIGHT/...
Issued at 155 PM MST Fri Jan 12 2024
Currently...Arctic boundary being analyzed along a line from
Pine Bluffs...northwest to Muddy Gap to Bondurant across Wyoming
this afternoon. North of the front...temperatures are below
freezing. Casper currently at 9 below zero...Douglas at 0 and
Chadron is reporting 3 below zero. South of the front...Pine
Bluffs is at 28 degrees...Cheyenne 23 and Laramie 21. Front
forecast to move through the Cheyenne area in the next couple
hours with plummeting temperatures and light snow.
Still have a chance for snow squalls this afternoon. Starting
to see the possible beginning of a convective line showing up
on radar. HRRR and RAP simulated radar showing a band of snow
developing north of Cheyenne along Interstate 25 and out by
Arlington on Interstate 80 at 23Z. Evening crew will need to
continue monitoring radar for possible snow squall warnings.
Kept the high wind warnings going for the Interstate 80
Corridor. Already hitting in Arlington with a peak wind of 73
mph at County Road 402. Other WYDOT sites have hit in that
zone...including Arlington and Strouss Hill. Further
east...we're seeing mid to upper 40 mph gusts over the Summit
and eastern foothills and the Cheyenne ASOS hit 44 mph earlier.
With the snow squalls developing...still think there is a chance
for some mixing down of stronger winds. Will let the current
warnings run their course.
By Saturday morning...700mb temperatures over southern Wyoming
forecast to be down to -23 to -26C...down from -13 to -15C
currently. Further north across Converse and Niobrara
Counties...700mb temperatures of -28 to -32C forecast. Going to
be brutally cold Saturday. Daytime highs will struggle to get
above 0F along and east of I-25...with low single digits above
zero west. Windchill Warnings look to be in good shape for all
locations with no changes planned.
Get a little break in mountain snow Saturday into Sunday as
arctic front pushes south and takes the snow with it. But snow
returns as the boundary begins to wave back north. NAM...GFS
and ECMWF all are hitting the Snowy and Sierra Madre Ranges
pretty hard with moderate to heavy snow. Getting snow totals out
there approaching 3 feet. Decided on a Winter Storm Watch once
again for Sunday morning through Monday afternoon.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
Issued at 155 PM MST Fri Jan 12 2024
Monday and Tuesday, much of central and northern CONUS will still be
under the influence of a potent arctic airmass. This will lead to
extremely cold temperatures and wind chills, as well as chances for
light snow. Monday will be the last bitter cold day as one more
strong push of cold air is progged to drop out of the north.
According to NAEFS 700 mb temperature percentile, this final push of
cold air will be anomalously cold, being in the 0.5th percentile for
temperatures. This will lead to Monday high temperatures below zero
for most locations with even colder overnight lows. Confidence in
these temperatures are high, as ensemble members for both the GFS
and ECMWF show very little spread in potential temperatures. Even
NBM probabilities for low temperatures below -10 are greater than
70% for much of the CWA Monday and Tuesday morning. Breezy
conditions are possible east of the Laramie Range on Monday and into
Monday night. This, combined with potential snow on the ground will
lead to dangerously cold wind chills during the day Monday and early
Tuesday morning. Wind chills, especially at night, will range from
-20 to -50 degrees across the area. Current Wind Chill Warnings are
in effect for the entire CWA through Tuesday morning. Tuesday
afternoon comes the return of high temperatures above 10 degrees.
This secondary arctic push will also bring some light snow to the
CWA during the day Monday. Overall, the best snowfall accumulations
will be in the mountains, where temperatures will be a bit warmer
than the surrounding areas. This will allow for better QPF amounts
on top of the orographic enhancement. The best area for snow
accumulation in the plains will be along the Interstate-80 corridor
from Rawlins to Cheyenne. Between 1 and 3 inches of snow will be
possible in this area from the snow on Monday.
Lastly, the wind will once again return in the long term, replacing
the bitter cold. This has the potential to be a long drawn out wind
event, with in-house guidance suggesting high winds in the usual
wind prones for almost two days. From Tuesday afternoon through late
Wednesday night strong MSLP gradients will exist across the Laramie
Range and points westward. 700 mb CAG-CPR height gradients are also
well above what would be needed to see high winds at Arlington,
ranging from 60 to 85 meters! Winds aloft are also sufficiently
strong, maxing out at 65 kts with great subsidence over the wind
prones. If these conditions hold true over the next several days,
the CWA could have a solid high wind event mid-next week.

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1032 PM MST Fri Jan 12 2024
The arctic cold front is through all terminals except KLAR at
this time, and it should pass through KLAR shortly. Snow showers
have decreased in intensity late this evening with the snow
squall threat concluded, but light to moderate banded snowfall
will continue to produce IFR conditions at times through the
early morning hours. There is uncertainty in the exact end time
of snow shower activity, but expect improving conditions after
13z at the latest. A drier but extremely cold day is expected
for Saturday, and most terminals should trend towards VFR by the
late morning.
