.UPDATE...

The aviation discussion has been updated for the 12Z TAFS.

.SHORT TERM /TODAY THROUGH THURSDAY AFTERNOON/...
Issued at 500 AM CST Wed Jan 21 2026

The main focus in this period will be on today's clipper system that
will deliver another round of light snow and strong winds to the
forecast area. The beginnings of this system are already showing up
on sat/rad with thicker cloud cover and light snow to our northwest
in western ND extending southeast into north central SD. For the
moment early this morning, our area has been in and out of pockets
of stratus/stratocu drifting southeast along with some areas of
flurries or snow showers. An upper trough axis will quickly move
southeast through the morning and midday hours. This will accelerate
a sfc low pressure system quickly into eastern ND by mid morning and
then into central MN during the first half of the afternoon. Timing
of the associated fropa slices through our forecast area during the
first half of the morning across our western zones and through our
eastern zones by late morning/midday. Light snowfall will spread
from north central sections of SD into central/eastern zones by mid
to late morning. Total accumulations will be up to 1 inch generally
north and east of a McIntosh to Gettysburg to Miller line. Some
upslope enhancement on the Prairie Coteau may push values to between
1 and 2 inches. The second part to this system will be increasing
northwest winds.

A 100-120 knot jet streak is progged to push across western SD and
our western zones today. Efficient mixing will push the strongest
gusts across the western half of our forecast area, basically west
of the James Valley. Our western zones(central SD) could see gusts
range between 45-50 knots between about mid morning through mid
afternoon. BUFKIT profiles at Pierre and Mobridge indicate gusts at
the top of the mixed layer range between 50-60 knots with average
speeds within the layer ranging between 35-45 knots between mid
morning and midday. However, guidance progs 8-10 mb 3 hour pressure
rises mid/late morning with the fropa and incoming sfc high across
central SD. The one caveat is that although there will be some cold
air advection starting to take place during that time across our
west, it's not substantially strong. Taking all this into account,
the feeling is wind gusts will approach or touch High Wind Warning
crit in a few spots for a short period of time, but mostly remain at
Wind Advisory levels(>45 mph)on average through the day. Have left
the Wind Advisory in place and will just have to monitor obs and
make changes if warranted. Regardless if gusts get to warning levels
or not, areas of blowing snow and reduced visibilities are likely,
especially in areas that have a fresh snow cover or during the
falling snow. However, new snowfall across parts of central SD today
could be limited lessening impacts to visibility. It may all depend
on the characteristic of the fresh snow on the ground or lack
thereof that will drive the blowing snow/low visibility hazards. For
locales that have had fresh snow or falling snow(north
central/northeast SD and west central MN), the strong winds will
pose hazardous travel conditions through this afternoon. The worst
cases will be found in open country and therefore will continue with
the Winter Weather Advisory.

Light snowfall will taper off during the afternoon hours with
perhaps some flurries hanging on into the late afternoon or early
evening. Winds will begin to diminish after sunset tonight with more
tranquil conditions developing. Temperatures will plummet overnight
into the single digits above and below zero but any residual cloud
cover will help. Thursday will be quite chilly but not as cold as
what's to come beyond this period. Guidance progs the arctic
boundary will descend south into the area during the mid morning to
mid afternoon time frame on Thursday. This will mark the leading
edge of a really cold air mass that will begin to move into our area
during the afternoon. Wouldn't be surprised to see temperatures fall
below zero across our northern/northeastern zones Thursday afternoon.

&&

.LONG TERM /THURSDAY EVENING THROUGH TUESDAY/...
Issued at 500 AM CST Wed Jan 21 2026

The main highlight in the long term will be the blast of arctic air
moving in over the region for the end of the week continuing through
the weekend. The coldest period, and therefore the dangerously cold
wind chills, will be Friday morning through Saturday morning. Models
are consistent on this impressive 1052mb high that will slide in
from the northwest, with the CWA on the southeastern side of this
elongated high at 00Z Friday. By 12Z Friday the center the high will
be over ~northwestern ND/Alberta. It will continue to track
southeast and then more easterly as the high will then centered over
the Upper Midwest by 12Z Saturday. By this time the Northern Plains
will be in between this high to our east and an area of low pressure
to our west over Montana and northwestward. Just to give you an idea
on how "high" this high is, the mean MSLP and climatological
percentile at 12Z Friday runs from 99.5% to all time max per
ECMWF/GEFS! This is about 3 standard deviations above climo for MSLP
per NAEFS and GEFS M-Climate! The return interval, meaning the
frequency of occurrence in the Jan 13-Feb03 1985-2012 timeframe is
both outside the 12Z CFSR climate and outside CFSR climate for all
time periods for NAEFS!

This arctic high will bring in quite the cold temperatures and
coldest of the winter season thus far (hopefully this will be it).
850mb temps between 00Z Friday-12Z Saturday runs about 2 to 3
standard deviations below climo per NAEFS with a return interval of
once every 5-10 years. The coldest period will be Friday morning as
by 06Z, 850mb temps (per grand ensemble mean) will run between -35
to -22C, coldest over northeastern SD. This is within the 0 to 3rd
percentile range per climo, lowest over over northeastern SD. By 12Z
Friday, temps are still running in the 20s to 30s below zero range
over the CWA at 850mb. 925mb temps will also run in the twenty to
thirties below zero. So forecast surface lows Friday morning are
forecast in the teens and twenties below zero. Looking at the NBM
5th percentile (for a worst case scenario) and temps could
potentially be -25 to almost -30F over the CWA if we have stronger
than forecast colder air already along with strong radiational
cooling and overall clear skies (besides our extreme southern CWA)
as winds are forecast to become light. Forecast wind chills range
from 30 below zero to potentially 45 below, coldest over
northeastern SD and especially over the Coteau. Due to this, an
Extreme Cold Watch remains in effect for locations east of the
Missouri River. Even during the day on Friday, 925mb temps will
range in the twenties below zero with daytime highs mainly in the
single digits to teens below zero. Prob of temps above zero is 15-
30%, highest over our extreme southern CWA. Wind chills even by the
afternoon will still be in the twenties to potentially 30 below
zero, coldest over the Coteau. EC EFI for both max and min temps
Friday morning/Friday day shows values of -0.9 to -0.99 and shift of
tails of zero! Even though its going to be cold, we will not be near
record cold temps at this point in time.

Saturday morning, it will still be cold but "warmer" than Friday
morning with 12Z temps at both 850/925mb in the twenties below zero,
which still runs in the bottom 3rd to 5th percentile per climo as we
will be on the western edge of this high by 12Z Saturday. So early
morning lows are only a couple of degrees warmer at any one
location, but still running in the teens and twenties below zero and
wind chills in the twenties to about 35 below zero. So this may only
warrant a Cold Weather Advisory. Highs will range in the single
digits below zero to about the lower to mid teens, warmest south
central SD. By Sunday morning, temps will range in the single digits
to teens below zero with daytime highs around zero to the mid teens.

By early next week the large deep upper troughing pattern we have
been dealing with will finally shift off to the east a bit as an
amplified ridge will build over the western CONUS and remain over
this area through at least the middle of next week with winds aloft
in northwest flow. The western CWA will see more of an influence
from this ridge while the eastern CWA will continue to be on the
backside of this upper trough. Anyways, temps will gradually increase
through the midweek with highs by Tuesday in the teens to lower 30s,
warmest south central SD. Precip wise, our only real chance (15-20%)
is Friday evening/early Saturday for light snow over portions of
south central SD.

.AVIATION /12Z TAFS THROUGH 12Z THURSDAY/...
Issued at 557 AM CST Wed Jan 21 2026

Terminals KABR,KATY,KPIR,KMBG

Deteriorating conditions are expected at all terminals this
morning as light snow moves through the area which will be
followed by increasing northwest winds. VFR conditions intially
this morning at KABR/KATY will quickly turn to MVFR/IFR cigs and
vsbys as light snow and blowing snow develop. Expect these
conditions to persist into the afternoon but improve once the
light snow ends. MVFR cigs/vsbys will be possible at KPIR/KMBG
through at least midday before improving during the afternoon
after the light snow ends. Blowing snow will still be possible
through the afternoon at KPIR/KMBG. As a strong upper jet mixes
down this morning, a few hours of low level wind shear will be
possible at KATY/KPIR/KMBG TAF sites.

556 AM CST Wed Jan 21 2026 /456 AM MST Wed Jan 21 2026/

This Hazardous Weather Outlook is for west central Minnesota,
central South Dakota, north central South Dakota and northeast
South Dakota.

.DAY ONE...Today and tonight.

Light to moderate snow will quickly move through the area this
morning and then begin to taper off during the afternoon. Strong
northwest winds will develop during the morning and gust between 35
to 55 mph and persist through late afternoon and early evening. The
combination of the fresh snow on the ground or new snow falling and
the strong winds will lead to areas of blowing snow and reduced
visibilities. Hazardous travel conditions will be possible with the
worst conditions occurring out in open country. Conditions will
improve during the evening.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.

A blast of bitterly cold arctic air pushes into the area on Thursday
and Thursday night and persists into the weekend. Breezy conditions
will increase the risk of blowing snow on Thursday. Dangerous wind
chills of 25 below to 45 below zero will be possible Thursday night
into Saturday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected at this time.
