Weak to moderate low level frontogenetical forcing, combined with forcing aloft ahead of a mid level trough, moved across western North Dakota during the evening of the 14th, and became stalled over central North Dakota during the overnight hours of the 15th.  Mid level warm air advection ahead of surface warm front, coupled with below freezing surface temperatures, combined with the forcing to result in an extensive area of freezing rain and sleet which fell through the morning hours of the 15th. The heaviest precipitation fell across north central North Dakota, where very hazardous travel conditions developed.
