The episode as NWS FSD wrote it up.
Snow, primarily associated with low pressure aloft, produced heavy accumulations over part of southwest Minnesota including the Worthington, Windom, and Jackson areas. Lesser accumulations were reported elsewhere in southwest Minnesota in a band just to the northwest of this area. The snow fell from the afternoon of January 14th into the predawn hours of January 15th. Increasing northwest winds and falling temperatures caused dangerous wind chills near the end of the event. The winds also caused a few areas of blowing and drifting snow.

NATIONAL WEATHER SERVICE SIOUX FALLS SD
1035 AM CST SUN JAN 14 2007
.DISCUSSION...
WATCHING CURRENT RADAR AND OBERSERVATIONS ACROSS THE CENTRAL PLAINS
AS SNOW DEVELOPING IN THE AREA. ONCE SATURATION OCCURS...SNOW WILL
BEGIN IN EARNEST ACROSS SE SD EARLY THIS AFTERNOON. MAIN QUESTION
WILL BE QFP AND SNOW AMOUNTS WITH THIS SYSTEM. EXPECTING 2 TO 4
INCHES OF SNOW ACROSS MOST OF THE CWA BY MONDAY MORNING...HOWEVER 4
TO 8 INCHES IS LIKELY IN A BAND FROM YKN TO FSD TO DVN. THE HEAVIEST
SNOW IS EXPECTED FROM LATE THIS AFTERNOON THROUGH THE EVENING HOURS
WITH BEST COMBINATION OF UPPER AND MIDLEVEL SUPPORT. ONE LIKELY
DAMPER ON HIGHER SNOWFALL AMOUNTS WILL BE INCREASING DRY NRLY FLOW
BY THIS EVENING. GIVEN LATEST VIS AND SNOW RATES ACROSS
NEBRASKA...WILL KEEP WITH SNOW ADVISORIES AND MAY EXPAND TO A FEW
MORE COUNTIES...BUT WILL BE CLOSELY WATCHING THE POSSIBLITY OF A
WINTER STORM WARNING IF FORECAST SNOW AMOUNTS GO ANY HIGHER.

.PREV DISCUSSION...
WELL THE MODELS HAVE FLIP/FLOPPED BIG TIME WITH STRONG UPR LVL
WAVE DVLPG IN COLORADO THIS MRNG GETTING KICKED OUT TO THE NE AS
UNDERFCST KICKER MOVES SWD THRU WRN U.S. SYSTEM WILL TAP INTO STG
SW TO NE MID LVL BOUNDARY AND MAXIMIZE AVBL MOISTURE WITH DVLPG
INFLOW FM ESE BTWN 850 AND 700MB. FOR NOW WENT WITH HEAVIEST AMOUNTS
OF SNOW IN ERN CWA WITH LIT WARMER AIR MASS AND AVBL MOISTURE...
BUT BASICALLY ANYWHERE ALG AND SE OF LN FM BKX TO PICKSTOWN SD HAS
THREAT OF CLOSE TO 6 INCHES. SO HAVE WINTER STORM WATCH IN ERN PTNS
OF SW MN AND NW IA FOR TNGT WITH SNOW ADVYS ELSEWHERE THRU SERN TWO
THIRDS OF CWA. LATER SHIFTS WILL HAVE TO MONITOR TO PUSH BACK
HEAVIER SNOW FURTHER NW INTO COLD AIR AS SNOW WILL BE VERY
EFFICIENT. NNWLY WINDS WILL PICK UP TO 15 TO 25 MPH MOST AREAS
TNGT...SO JUST WENT AREAS OF BLWG SNOW FOR NOW. PREV FCST TEMPS IN
THE BALLPARK...BUT LWRD SOME WITH EXPCD NEW SNOW COVER FOR MON THRU
TUE. NO TIME TO MESS WITH EXTD...BUT VARIOUS MODELS SHOW SOME
POTENTIAL FOR QUASI ACTIVE PATTERN.

.AVIATION...
UNTIL SIGNIFICANT SNOW STARTS TO MOVE INTO AREA AFTER 18Z OR
SO...AVIATION CONCERNS WILL BE LIMITED TO A FEW AREAS OF CIGS 15
HUNDRED TO 3 THSD FEET AGL FROM AROUND MWM TO FSD TO PKS AND S.
BANND OF VERY LGHT SNOW CUD NICK THE VSBY BRIEFLY DOWN TO 5 MILES
SOMEWHERE BUT LITTLE SUPPORT FOR FURTHER REDUCTIONS. FROM 18Z TO 00Z
WE SHOULD SEE STEADY LOWERING TO VSBYS BLO 3 MILES IN SNOW OVER MOST
OF AREA AND THIS WILL CONT WELL AFTER 00Z...PROBABLY IMPROVING
SIGNIFICANTLY 06Z TO 12Z MON. THIS SHOULD BECME WIDESPREAD OVER MOST
OF FCST AREA BY 00Z THOUGH THE NWRN CORNER INCLUDING HON COULD
ESCAPE MUCH OF THIS. WHILE CIGS SHOULD BE MOSTLY 1 TO 2 THSD FEET
DURNG SNOW...THE HEAVIEST SNOW COULD SEE A LOWERING TO BLO 1 THSD
FEET. WILL PRBLY GO WITH THIS IDEA IN 12Z TAFS AT LEAST AT FSD AND
SUX.
