The National Weather Service recently warned people in parts of Minnesota and Wisconsin that they could be hit with winter weather and significant snowfall ahead of the Thanksgiving holiday, although the exact timing wasn't clear.

Now, even though Thanksgiving week has started warm and sunny, that will quickly change as a winter storm appears to be making its way into Minnesota and Wisconsin as early as Tuesday morning, impacting travel into as late as Wednesday evening in some areas.

To prepare people in the areas of impact, the National Weather Service officially issued a series of 8 Winter Storm Watches, with the hope that people in these areas can adjust travel plans to avoid driving in hazardous conditions.
