I am expecting a storm system to move into the region in the next 24 hours, with the event beginning as rain and transitioning to snow. This initial phase will drop 2-4 inches across North Dakota, with 1 inch or less expected farther to the south.
However, a sudden rain-to-snow change will occur in northern Minnesota and extreme northeast North Dakota, bringing over 8 inches of snow to the mentioned areas. Some spotty blizzard conditions are possible, especially in rural areas.
Heavier snow is expected in Canada, upwards of 18 inches in some spots.
