Part 3/7:
The forecast outlines a transition from mild temperatures to an impending major Arctic blast that promises to plunge temperatures well below average for many. As temperatures across the northern parts of the country are expected to drop to lows of -20°F or colder, southern regions like eastern Colorado and Texas may also experience their coldest temperatures of the season.
Between January 20 and January 25, a major temperature shift is expected to prevail across the Great Lakes and Ohio Valley, where frigid conditions will become commonplace.
