...BLIZZARD WARNING REMAINS IN EFFECT UNTIL 6 PM CST THIS
EVENING...
...WIND CHILL WARNING IN EFFECT UNTIL NOON CST TUESDAY...

* WHAT...Blizzard conditions this afternoon. Dangerously cold wind
  chills expected. Wind chills as low as 40 below zero expected
  through Tuesday morning. Additional snow accumulations of less 
  than one inch. Winds gusting as high as 40 mph.

* WHERE...Portions of northeast South Dakota and west central 
  Minnesota.

* WHEN...For the Wind Chill Warning, until noon CST Tuesday. For 
  the Blizzard Warning, until 6 PM CST this evening.

* ADDITIONAL DETAILS...Plan on slippery road conditions. Areas 
  of blowing snow could significantly reduce visibility. The 
  hazardous conditions could impact the morning or evening 
  commute. The dangerously cold wind chills could cause 
  frostbite on exposed skin in as little as 10 minutes.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Wind Chill Warning means the combination of very cold air and
the wind will create dangerously low wind chill values. Frostbite
can occur quickly and even hypothermia or death if precautions
are not taken. 

A Blizzard Warning means severe winter weather conditions are
expected or occurring. Falling and blowing snow with strong winds
and poor visibilities are likely. This will lead to whiteout
conditions, making travel extremely dangerous. Do not travel. If
you must travel, have a winter survival kit with you. If you get
stranded, stay with your vehicle. 

In Minnesota, the latest road conditions can be obtained at
511mn.org, or by calling 5 1 1. In South Dakota, the latest road
conditions can be obtained by calling 5 1 1.

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 31, 2:12 AM CST, 3 hours 48 minutes earlier.

Area forecast discussion, Dec 31, 2:12 AM CST, 3 hours 48 minutes before
Area Forecast Discussion
National Weather Service Aberdeen SD
212 AM CST Mon Dec 31 2018

.SHORT TERM...(Today and Tonight)
Issued at 212 AM CST Mon Dec 31 2018

Main concerns for today, of course, are snow/blowing snow/winds.
Pressure bubble is finally starting to make some headway south and
should continue to push main baroclinic zone south in the process.
However, accumulating snow looks to continue across the CWA through
at least the morning hours today before finally shifting off to the
south of the forecast area. The highest snow amounts look like
they'll occur over the Sisseton Hills/Coteau region, where around 6
or so inches total looks possible. The latest HREF/HRRR support this
idea.  Given limited coverage of 6 inch + amounts, will maintain
advisory and not upgrade. That said, still feel near blizzard
conditions are possible across the region yet this morning with
winds occasionally gusting to near 40 mph. Currently the greatest
pressure rises are forecast to slide through the western CWA and
this may be where winds end of the strongest through the morning
hours. Nonetheless will have to keep an eye on the wind and vsbys in
case an upgraded is needed due to worsening conditions.  Highs today
should not be much higher than the morning lows.

For tonight pcpn will end and there should be some clearing although
perhaps not completely clear. With arctic air in place, and
slackening winds, it should be cold, with some areas able to reach
20 below by morning. Wind chills will continue to be an issue so
that advisory will be allowed to continue.

.LONG TERM...(Tuesday through Sunday)
Issued at 212 AM CST Mon Dec 31 2018

We open the period with surface high pressure overhead, moving
slowly east and parts of the western CWA already under southerly
return flow. We have a widespread snowpack, so temperature recovery
will be much delayed and blended guidance temperatures
Tuesday/Tuesday night are appropriate given 925mb temperatures
initially starting at -20C. This layers temperature does gradually
warm with westerly flow at 925mb, -10 to -8C by Tuesday night but
given the starting point (readings at the surface well below zero in
spots) readings will probably fall at least a handful of degrees
overnight. Favorable mixing conditions continue into Wednesday and
Thursday with westerly flow in the low levels, with 925mb
temperatures above freezing. I would anticipate some feedback from
our snow-pack, limiting temperature recovery despite favorable
mixing, and wouldn't be surprised if we have to deal with some
fog/low stratus given its a modified Pacific airmass moving into the
region.

&&

.AVIATION...(For the 06Z TAFS through 06Z Monday Night)
Issued at 1123 PM CST Sun Dec 30 2018

The only terminal not reporting snow yet is KPIR, but that should
be changing within the next couple of hours, and KPIR should be
reporting snow, too. Sub-VFR cigs and visbies in falling and
blowing snow is expected over the next 12 to 18 hours, before VFR
gradually returns to the region. Strong northerly winds have
picked up at KABR/KMBG and will be spreading down to include the
KATY/KPIR terminals over the next few hours.
