What happened
The episode as NWS FGF wrote it up.
A Colorado Low moved into the central plains during the early evening of the 15th, then tracked northeast to near Duluth, Minnesota, by the afternoon of the 16th. Snow moved into the southern Red River Valley on the evening of the 15th, then expanded northward overnight. However, drier air eventually fed into the southern Red River Valley and west central Minnesota, limiting the snow totals there. The most snow, around a foot, fell in a narrower band from Jamestown to Michigan to Cavalier, in North Dakota. Outside this band, a broader four to six inches of snow fell along with breezy winds and a little mixed precipitation.
What forecasters said that day

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND
257 PM CST TUE DEC 15 2015
.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY NIGHT)
ISSUED AT 300 PM CST TUE DEC 15 2015
A VERY CHALLENGING STORM SYSTEM UPCOMING TONIGHT THROUGH WED
NIGHT. MODELS ARE IN GOOD AGREEMENT...WITH THE NAM AND ALL OTHER
MESOSCALE MODELS INDICATING A DRY SLOT WILL WORK IN FROM THE SOUTH
AFTER THE MAIN SNOW BAND COMES IN TONIGHT. MOST OF THE QPF/SNOW
MAPS HAVE SIDED WITH THE NAM AND MESO MODELS INDICATING THIS
TREND.
FOR TONIGHT AND WED...THERE COULD BE A PERIOD OF SOME FREEZING
DRIZZLE BEFORE THE MAIN SNOW BAND ARRIVES FROM SOUTH TO NORTH.
THIS WILL CAUSE VERY ICY ROADS...AND TRAVEL IMPACTS. A MODERATE TO
AT TIMES HEAVY BAND OF SNOW SHOULD LIFT INTO THE SOUTH AFTER
00Z...INTO THE GFK AREA AROUND 7-8Z THEN INTO THE FAR NORTH BY
12Z. SNOW RATES SHOULD BE 1-2 INCHES PER HOUR SO A QUICK 2-5
INCHES IS POSSIBLE OVERNIGHT...MAKING A VERY HAZARDOUS MORNING
COMMUTE WITH SNOWY/ICY ROADS AND LOW VISIBILITY IN FALLING SNOW.
NORTHERLY WINDS WILL INCREASE IN THE FAR WEST BY 15Z WED THEN
INCREASE INTO THE VALLEY BY 00Z THU. THERE WILL BE 35-40KT TO MIX
FROM 925MB BY 00Z THU...SO SOME BLOWING SNOW ISSUES WILL DEVELOP
IN OPEN AREAS. NOT EXPECTING A BLIZZARD SINCE WINDS WON/T BE
STRONG ENOUGH...BUT AREAS IN OPEN COUNTRY WILL LIKELY BE AROUND
1/2SM AT TIMES WITH WRAPAROUND SNOW PERSISTING INTO WED NIGHT.
TOTAL SNOW ACCUMULATIONS SHOULD BE FAIRLY UNIFORM FROM 4 TO 8
INCHES IN ALL AREAS...WITH AN ENHANCED BAND OF 6-8 MORE LIKELY NOW
IN THE NORTHERN AREAS JUST NORTH OF THE ADVANCING DRY SLOT. WE
SHOULD SATISFY OUR LOCAL WARNING CRITERIA OF 4 INCHES IN 12HR AND
WINDS 25MPH OR HIGHER CREATING HAZARDOUS CONDITIONS...IN ADDITION
TO ANY FREEZING DRIZZLE THAT FALLS PRECEDING THE SNOW. BOTH THE
WED MORNING AND AFTERNOON COMMUTES WILL BE IMPACTED...ALTHOUGH THE
WED MORNING COMMUTE WILL LIKELY SEE THE MOST SEVERE IMPACTS.
ON WED NIGHT...SOME BLOWING SNOW WILL PERSIST UNTIL 3Z OR SO AND
THERE SHOULD BE SOME LIGHT SNOW WRAPPING AROUND PARENT LOW.
.LONG TERM...(THURSDAY THROUGH TUESDAY)
ISSUED AT 300 PM CST TUE DEC 15 2015
ON THU...TEMPS WILL REMAIN BELOW NORMAL WITH PERHAPS SOME LIGHT
SNOW INTO THE EAST.
ON FRI...IT WILL BE COLD WITH HIGHS STRUGGLING IN THE SINGLE
DIGITS ABOVE ZERO...GIVEN A COLD AIRMASS AND FRESH SNOW. OVERNIGHT
LOWS MAY FALL WELL BELOW ZERO.
FOR FRIDAY NIGHT THROUGH TUESDAY...FRI NIGHT STILL LOOKING LIKE A
COLD NIGHT WITH SFC HIGH PRESSURE NEARBY ALONG WITH LIGHTER WINDS
AND FRESH SNOW. FLOW TURNS A LITTLE MORE ZONAL SAT/SUN WITH A WEAK
SHORT WAVE CROSSING THRU ON SUNDAY/SUN NIGHT. THIS COULD SPREAD A
LITTLE LIGHT SNOW TO AREAS ALONG THE CANADIAN BORDER. ON THE HEELS
OF THIS WAVE ANOTHER ONE MOVES IN BY MONDAY NIGHT/TUE WHICH COULD
BRING ANOTHER SHOT AT SOME LIGHT SNOW. TEMPS LOOKING TO HOLD NEAR
NORMAL AFTER THE CHILLY FRI NIGHT.
&&
.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON)
ISSUED AT 130 PM CST TUE DEC 15 2015
GETTING SOME FREEZING DRIZZLE AT KFAR/KBJI AND THAT COULD CONTINUE
INTO THE AFTERNOON AND MAYBE EVEN THE EVENING. ARRIVAL TIME OF THE
SNOW CONTINUES TO BE SLOWER...SO DELAYED THE ONSET OF THE LIGHT SNOW
A LITTLE LATER THAN PREVIOUS SET OF TAFS. ONCE THE SNOW STARTS IT
SHOULD QUICKLY SHIFT TO HEAVIER RATES AND CONTINUE INTO EARLY WED.
THEREFORE CEILINGS WILL STAY LOW THROUGHOUT. WIND SPEEDS MAY NOT
PICK UP UNTIL AFTER THE HEAVIER SNOW BAND MOVES THROUGH...SO KEPT
MOST OF THE HIGHER WIND GUSTS UNTIL THEN.
