From around the night of December 26 and December 27, this strengthened cold air mass will affect the Northeast and North Central regions. From the night of December 27, the cold air mass will be strengthened and affect the Northwest and North Central regions. The Northeast wind inland will strengthen to level 2-3, and coastal areas to level 3-4.
