Forget a white Christmas. Folks across the far northern tier of the nation will see a white Thanksgiving, with mounds of snow likely before the weekend comes to an end.

"In the north-central U.S., a storm will bring heavy snow and gusty to high winds over parts of the northern Plains and Upper Midwest Tuesday Nov. 25 before moving across the Great Lakes with heavy lake-effect snow Wednesday Nov. 26 into Thanksgiving Day," the National Weather Service said.

Blizzard warnings have been hoisted by the weather service for portions of South Dakota, Minnesota, Wisconsin and Michigan, where "travel could be very difficult to impossible," the weather service said.

Then, yet another snowstorm is likely for much of the north-central U.S. and Midwest over the weekend, which will lead to travel headaches for returning Thanksgiving travelers.

The first system is expected to strengthen and expand in size as it begins to interact with another frontal system and will gradually push eastward by Wednesday, Nov. 26, the weather service said. This will bring more snow chances for Upper Midwest and Upper Great Lakes on Wednesday.
