An upper level disturbance and area of surface low pressure brought a prolonged period of precipitation to the Northern Plains from Tuesday night, December 14th, through Thursday morning, December 16th.
Freezing rain and sleet developed over west and central portions of the state Tuesday evening into Wednesday morning. The freezing precipitation occurred as warm air aloft spread east into North Dakota combined with subfreezing surface temperatures. The freezing rain started over northwest North Dakota first, then developed south and east into early Wednesday morning. While the freezing rain created icy road conditions across much of the west and central, northwest and north central North Dakota were especially hit hard with over one tenth of an inch of ice accumulations on structures and surfaces.
The freezing rain and sleet eventually changed over to all snow through the morning hours of Wednesday. As conditions evolved Wednesday and Wednesday evening, a band of moderate to heavy snow developed first over the Turtle Mountain region and around the Devils Lake basin during the daylight hours of Wednesday morning, then eventually stretched south into the James River basin as the day wore on. Snowfall continued Wednesday night and into Thursday.
