What forecasters said that day

The local office's own words before this blizzard warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Aberdeen, SD wrote its last area forecast discussion before this blizzard warning went out at Dec 3, 11:33 AM CST, 3 hours 35 minutes earlier.

Area forecast discussion, Dec 3, 11:33 AM CST, 3 hours 35 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Aberdeen SD
1133 AM CST Sun Dec 3 2017

.UPDATE...
Issued at 1047 AM CST Sun Dec 3 2017

The current forecast for today looks good overall. Did increase
sky cover through the rest of the day. With the cloud cover, have
lowered highs a few degrees as well.

&&

.SHORT TERM...(Today through Tuesday Morning)
Issued at 419 AM CST Sun Dec 3 2017

So, today is the last day of mild temperatures. 925mb temperatures
are still quite warm, around +7C. Mixing to the surface yields
highs in the 40s and 50s, despite a southeast component and
increasing high clouds. Main focus will be on an upper trough
crossing the Rockies today, and ejecting into the plains
tonight/early Monday. We are seeing some good 00Z/12Z run to run
continuity with deterministic guidance, so confidence has
increased. Mixed winds (mid 50kts), gradient (20mb across the
state), and pressure rises (peak around 15mb/6hrs) continues to
support wind gusts close to 60mph. We continue to see evidence for
a banded/trowal type feature as this low wraps up across the
area, and forecast timing/intensity attempts to consolidate the
ARX/NMM and 00Z NAMNest outcomes, which are fairly close in
evolution. Should be fairly transitory at least, but given the
winds under this feature, expect zero visibility when it is
snowing. Given bare ground across the area, it can likewise be
expected that visibility will be generally unaffected outside of
this area of intense snowfall though there may be pockets of
lighter snow to contend with. And we are taking about an
intense/heavy snowfall band as GFS still shows a peak of 40
microbars of lift in the 600-700mb layer around 21Z across the
northeast. Decided on a winter storm watch for blizzard conditions
where confidence is highest, but will also likely need some sort
of winter weather or high wind headlines for other parts of the
CWA.

.LONG TERM...(Tuesday through Saturday)
Issued at 419 AM CST Sun Dec 3 2017

Not much has changed with the models with the large scale flow over
the region through the long term. A large upper level low pressure
trough is expected across the eastern U.S. through the long term
with a western U.S. high pressure ridge. Therefore, deep cold
northerly flow is expected through the period with several short
wave troughs/clipper systems dropping across the region. With the
new snow cover across the region and to our north, temperatures will
be colder than normal through the period mainly in the 20s and lower
30s. Upper teens are expected across the east on Tuesday. The models
do show some rising 50h heights on Saturday as surface winds become
southwest. Although with the snow cover and poor mixing, dont expect
temperatures to be affected much.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday Afternoon)
Issued at 1128 AM CST Sun Dec 3 2017

VFR conditions can be expect for all terminals through 10Z Monday.
A strong area of low pressure will lower cigs tonight, reaching
MVFR before sunrise. This system will bring increasing northerly
winds along with moderate snowfall. Flying conditions will become
IFR during the mid to late morning hours.

406 AM CST Sun Dec 3 2017 /306 AM MST Sun Dec 3 2017/

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

.DAY ONE...Today and Tonight

Light precipitation will begin to move into the region late
tonight, however we expect most of the area will still be mild
enough that this will fall as rain or possibly light snow. Gusty
winds will also start to develop late tonight, though the
strongest winds are reserved for the day Monday.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Low pressure moving across the area Monday will result in wind
gusts topping out around 60mph and falling temperatures.
Precipitation, mainly in the form of a band of moderate to high
intensity snow, will follow the low as it transitions across the
region. Where snow is falling we can anticipate poor visibility
and blizzard conditions. Outside of this snowfall band, visibility
should be good. Snow accumulations will generally range from 1 to
4 inches with locally higher amounts for the Sisseton hills and
western Minnesota.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
