The episode as NWS FSD wrote it up.
Northwest winds gusting to over 50 mph, along with existing loose snow cover, caused blowing snow with visibilities of a quarter mile or less in areas. The low visibilities were widespread in the Huron to De Smet area, where travel was impossible for most of the daytime hours. Elsewhere in southeast South Dakota, the worst conditions were more localized. Several schools, businesses, and roads, including parts of Interstates 90 and 29, closed as the blizzard developed. Travel remained difficult as the storm abated because of the heavy drifting snow.

.DISCUSSION...
WINTER WX ADVY HAS TURNED OUT WELL AS EVEN LIGHT SNOW ACCUM HAVE
BLOWN INTO PLENTY OF BLOWING SNOW ESPLY IN OPEN AREAS WITH THESE STG
WINDS. SOME AREAS IN THE WRN FCST AREA...EVIDENTLY DURING THE BEST
FALLING SNOW...HAVE REPORTED NEAR WHITEOUT CONDS DURG THE NIGHT.
WITH VARIABILITY OF CONDS AND SENSITIVITY OF VSBYS TO FALLING
SNOW...WHICH WILL PRBLY ABATE A LTL NEXT SVR HRS WRN FCST AREA...
CONDS ARE NOT WDSPRD AND CONSISTENT ENUF TO UGRADE TO WARNING.
SENSITIVITY TO FALLING SNOW WUD NOT BE SO GREAT IF WE HAD MORE THAN
A CPL INCHES ON TOP OF THE EXITSING SOLID SNOW/ICE. NEVERTHELESS WE
HAVE A GOOD STG WINTER WX ADVY WHICH NEEDS TO BE EXPANDED INTO FAR
ERN FCST AREA WHERE SO FAR LTL SNOW HAS FALLEN TO BLOW. CURNT STLT
AND RADAR...ESPLY WELL SEEN ON MVX RADAR...SHOWS SIGNIFICANT SHOT OF
SNOW HVY ENUF TO PRODUCE THOSE CPL INCHES THAT AREA. WILL CONT TO
LET WINTER WX ADVY AND WIND ADVY CO EXIST...AS FEEL WITH DROPOFF OF
FALLING SNOW...AND THE FACT THAT WINDS CAN DECREASE SOME AND STILL
BE IN ADVY CRITERIA...WE NEED TO LET THE WIND ADVY RUN LONGER THAN
THE WINTER WX ADVY AS WE HAVE BEEN DOING.
ERYR THOUGHTS OF GETTING CLOSE TO HI WIND CRITERIA IN NERN CRNR OF
FCST AREA/ SWRN MN/ HAVE ABATED WITH NAM BL WINDS NOT QUITE AS STG
AS SECONDARY UPPER WV ROTATES SWD OVER AREA. THIS WV WILL CAUSE THE
ABV MENTND INCRS IN SNOW OVER ERN FCST AREA TDA AS SNOW DCRSES SLWLY
OUT W. BY MID/LATE AFTN WE WILL GO TO A MORE GNRL W TO E DCRS IN
SNOW WHICH WILL PICK UP STEAM THIS EVE...AGAIN A GOOD REASON TO KEEP
WIND ADVY BEYOND WINTER WX ADVY. IF WE HAD 6 INCHES OR SO OF
BLOWABLE SNOW THEN CONDS WUDNT IMPROVE SO MUCH WITH THE DECREASE IN
FALLING SNOW.
DONE EXPECT TEMPS TO GO UP ANY TDA...PERHAPS JUST LEVEL OUT FOR A
FEW HRS FROM THE CURRENT COOLING. OTRW...GUIDNCE TEMPS VARY FROM
CLOSE TO A FEW DEGS TOO WARM NEXT CPL DAYS.
FOR REST OF FCST WILL KEEP CHC LGT SNOW S FOR LATE TUE NGT AND WED.
GFS STILL SHOWS THIS WEAK SYS PRETTY WELL EVEN THO NAM AS OFTEN
HAPPENS HAS IT EVEN WEAKER AND AS OF AREA. CURRENT COLDER TEMPS WILL
BE REINFORCED EVEN MORE WITH COLD ARCTIC PUSH BHND THIS SYS. ERN
CANADIAN UPPER LOW WHICH BRINGS THIS COLD PUSH MOVES ON EWD...
ALLOWING FOR A DECENT WARMING TREND...WITH DRY WX...TO ARRIVE BY THE
WEEKEND. ECMWF DELAYS THE WARMING A BIT WITH A BETTER FRI NGT/SAT
SECONDARY WAVE AFTER CANADIAN LOW MOVES EWD. HWVR IT BRINGS THE
WARMING IN STGLY BY SUN.
&&
.AVIATION...
MVFR TO IFR VSBYS WILL CONTINUE THRU THE MORNING WITH -SN AND
WIDESPREAD BLSN EXPECTED. SUSTAINED WINDS AT 25 TO 30 KTS AND GUSTS
UP TO 40 KTS WILL CONTINUE THRU LATE AFTN...THEN DECREASE THIS EVE.
VSBY SHOULD BEGIN TO IMPROVE THIS EVE AS LOW PROGRESSES EAST...GUSTS
START TO LESSEN...AND FALLING SNOW MOVES OUT OF THE FA. CIGS SHOULD
REMAIN RELATIVELY CONSTANT IN THE MVFR CATEGORY THRU THE PD. /LAFLIN
