A Winter Storm Watch is in effect from North and South Dakota, Minnesota, Iowa, northern Illinois and northwestern Indiana. The storm could leave as much as six inches of snow in these areas. Much of this area has already experienced heavy snowfall during the winter with some areas having received record snowfall for the winter season. Cold air is expected to follow the storm system and that will keep the snow on the ground for several days. The cold air will sink southward into the Southeast by late in the weekend lowering temperatures to near freezing by Easter night across portions of North Carolina.
