Blizzard in Wyoming, December 22, 2022

Name: Blizzard in Wyoming, December 22, 2022
Start: 2022-12-22T07:00
End: 2022-12-22T19:00
Location: Wyoming

December 22, 2022 · NWS UNR · 1 event in 1 county or zone

An Arctic cold front brought some snow, along with extremely low temperatures, strong winds, and bitter cold wind chills. Light amounts of new snow, along with considerable, blowable snowpack from the previous week's blizzard, combined with the strong winds to produce a period of blizzard or near blizzard conditions across the northeastern Crook County plains.

Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
410 AM MST Thu Dec 22 2022

.DISCUSSION...(Today Through Wednesday)
Issued at 106 AM MST Thu Dec 22 2022

Current surface analysis shows surface arctic high pressure over
Wyoming moving our way today. Extreme cold and very low wind
chills span across the forecast area. Current temperatures range
from -15 to -30 in the area, with wind chill values ranging from
-35 to -60. While winds have tapered off a bit, still expect
 enough gusts to keep in wind chill warning criteria through
 Friday afternoon. Did extend the wind chill warning for our
 eastern most counties through Saturday morning, while other areas
 of the western SD and northeast WY may have to downgrade to a
 wind chill advisory for the latter half of Friday into Saturday.

Wind forecast remains on track in the short term. While no new
snow is expected, blowing snow will continue to bring low
visibilities and blizzard conditions in some areas. HRRR, NAM, and
RAP models all show widespread northwest winds 25-30 mph
sustained, with gusts up to 60 mph possible this afternoon. The
main question though will be how much blowable snow will be
available, given snow age. Have added south central SD into the
Blizzard warning through Thursday given the strong winds and
amount of blowable snow we have seen thus far. NAEFS percentiles
keep us in the 95th percentile or higher on winds through Saturday
morning, before finally seeing a break over the weekend.

Looking ahead, GFS and the EC show another boundary moving through
later Christmas day. While it doesnt look like there's much
moisture with this front, might see some light snow and winds pick
back up Sunday night. Models do trend warmer starting next week as
ridging builds over the western CONUS, and we may see above
freezing temperatures finally return to the area.

.AVIATION...(For the 12Z TAFS Through 12Z Friday Morning)
Issued At 407 AM MST Thu Dec 22 2022

Strong winds will result in areas of blowing and drifting snow
with IFR/LIFR visibility. The worst conditions will be on the
plains north and east of the Black Hills as winds increase, with
gusts of 50 to 60 mph possible. Some patchy MVFR/IFR ceilings are
possible over the Black Hills and northeastern Wyoming, but most
areas will have mostly clear skies.
