Part 4/9:
This morning, temperatures remain mild, but the impending Arctic front will soon transform the weather landscape. While rain is expected from the line of showers moving across the Ohio Valley, cooler air will filter in progressively, setting the stage for the upcoming Arctic air invasions.
For much of the western states, particularly from the Pacific Northwest down into Arizona and New Mexico, this surge of cold air will primarily impact regions east of the Continental Divide.
