The episode as NWS FGF wrote it up.
On the heels of the first early December heavy snow producer (across southeast North Dakota and portions of northwest and west central Minnesota), a second heavy snow event followed roughly two days later. Six to 9.5 inches of snow fell along a corridor from northern Towner County (ND) to southern Grand Forks County (ND) to central Wadena County (MN). When combined with the snow totals from the prior early December event, many locations ended up with 15 to 20 inches of snow. This was good news for many snow related business in the area, which had not had this much early December snow for a number of years. As far as meteorological details, an area of surface low pressure tracked from eastern Montana to near Sioux Falls, SD. A fairly strong vorticity maximum was evident on water vapor imagery along the heavy snow path. The system also had a coupled upper jet structure to aid in providing strong lift. Quite a few rural schools cancelled classes or events early on Tuesday (4th) or early on Wednesday (5th).
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Grand Forks, ND wrote its last area forecast discussion before the first event at Dec 4, 4:30 AM CST, 3 hours 8 minutes earlier.
