Area Forecast Discussion
National Weather Service Sioux Falls SD
1201 PM CST Fri Dec 8 2023

.KEY MESSAGES...

- Not as warm, but still well above normal temperatures today.

- Periods of gusty west to northwest winds in excess of 30-35
  mph today through Saturday. Wind gusts will remain below
  advisory levels (45 mph) today, but some areas could approach
  those speeds early Saturday.

- Quick-moving band of light snow late tonight into Saturday
  morning. Localized areas greater than an inch are possible,
  and strong winds with the falling snow may create difficult
  travel at times. Some uncertainty in how far southeast light
  accumulations will extend.

- Dry conditions return Saturday night through much of next
  week, with temperatures near to slightly above normal.

&&

.DISCUSSION...
Issued at 352 AM CST Fri Dec 8 2023

Gusty west winds will prevail across the region today, ushering in
the first shot of cooler air, though high temperatures in the upper
40s to mid 50s today are still well above normal for early December.

HRRR/RAP forecast soundings do show ~40kt winds at the top of the
mixed layer this morning, mainly west through north of Sioux Falls.
Cannot rule out an isolated gust that approaches advisory criteria
in these areas. However, gusts to 45 mph are not expected to be
widespread or persistent, so opted to hold off on any wind headlines
for today. These winds, combined with dry vegetation will lead to
another day of High to Very High grassland fire danger, despite
moderate humidity levels only falling into the 40-50% range.

The gusty winds really do not subside much tonight as secondary shot
of cold advection this evening enhances low level mixing, and could
even see spotty sprinkles work into the Highway 14 corridor this
evening as a shallow unstable layer develops above 850mb.

Main focus for precipitation chances, though, will be on approaching
upper level trough associated with the aforementioned secondary cold
front, which swings through the northern Plains tonight-Saturday.
With column fully below freezing before precipitation begins, should
see only light snow with this system, with the main question being
"how much?". Latest ensembles have trended lower with QPF amounts
from the previous forecast, with ECENS/GEFS probabilities of 0.10"
or more liquid equivalent have decreased to 20-40% across most of
the Highway 14 corridor and extending south toward I-90 in areas
west of Sioux Falls (with much higher probabilities farther north
toward the Sisseton Hills). HREF probabilities are similar, perhaps
a bit higher in the 40-50% range. This leads to a slight decrease in
snowfall amounts from previous forecast, though pockets of an inch
or more are still possible in portions of southeast SD/southwest MN
by midday Saturday. Another trend seen in hi-res models tonight is
for the band of snow to break up/dissipate as it drifts east into
northwest Iowa Saturday morning, and as a result have decreased
precipitation chances a little more quickly through the late morning
to early afternoon.

Despite the decrease in expected snowfall amounts, soundings still
show 40+kt atop the mixed layer while the snow is falling west of
the I-29 corridor. Ensembles support the strong winds with better
than 50% probability of gusts in excess of 40 mph, also focused west
of I-29 Saturday morning. With no existing snow cover and new snow
generally less than an inch, anticipate that any blowing snow will
primarily be a concern during periods of falling snow Saturday
morning, but anyone with travel plans late tonight into Saturday,
especially west and north of Sioux Falls, will want to monitor the
latest road and weather conditions and forecast before heading out.

Northern Plains remains in northwest flow through midweek, which
should provide for dry weather with near to slightly above normal
temperatures, though this may be dependent on amount of new snow
cover in some locations. By Thursday, seeing a trend toward an upper
ridge building back into the Plains, which should push temperatures
a bit farther above normal by the end of the week.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 1201 PM CST Fri Dec 8 2023

Breezy west-northwesterly winds will continue, briefly becoming
weaker during the early evening hours before increasing again
overnight. As a cold front moves through the area overnight and
exits off to our east by the morning hours, a quick moving band of
light snow will trail behind it. This will result in MVFR cigs, with
pockets of IFR, along with MVFR and IFR visbys due to the
combination of falling snow and strong winds. Snowfall amounts will
be highest for areas north of I-90 where up to an inch is expected,
though pockets of up to 2 inches are possible, while areas south of
I-90 should remain below an inch. Snow moves east of I-29 by the
afternoon hours.

Minnesota, central South Dakota, east central South Dakota, south
central South Dakota and southeast South Dakota.

An area of light snow will move into southeast South Dakota and
southwest Minnesota after midnight tonight. Northwest winds gusting
as high as 35 to 40 mph will accompany the light snow, which may
cause travel difficulty due to the falling and blowing snow.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.

Areas of light snow will continue into Saturday morning, with light
accumulations of a half inch to an inch likely by midday Saturday.
Gusty northwest winds will continue to create patchy blowing and
drifting snow as well.
