From the US National Weather Service Grand Forks North Dakota:

"Late Wednesday into Thursday, there is a high chance of blizzard conditions in the northern half of the Red River Valley and northeastern North Dakota and a medium chance for blizzard conditions in southeastern North Dakota and southern Red River Valley. This includes whiteout conditions and very strong winds. If you have travel plans during this time within these regions, consider altering them as dangerous to impossible travel conditions accompany this potential. If you must travel, ensure your vehicle has a winter survival kit. Also, widespread closures and disruptions to infrastructure may occur."
