Stormy Heartland pattern to extend into February
The sprawling storm system that has been affecting the West will move eastward, crossing the central and southern Plains on Saturday and the Ohio Valley on Sunday.
Subsequently, the system should stall and intensify near the middle Atlantic Seaboard, resulting in storm impacts (e.g. wind and snow) lingering into Tuesday across parts of the Northeast.
Wintry precipitation will cover a broad area, stretching from the Midwest into the middle and northern Atlantic States, while showers and thunderstorms will briefly affect the Southeast.
Meanwhile, a new Pacific storm system will arrive in the Northwest during the weekend. Although that system will take a slightly more northerly path across the West, drought-easing precipitation could again reach as far south as California and the Great Basin.
Looking ahead, the 6- to 10-day outlook calls for the likelihood of below-normal temperatures across the western half of the U.S., while warmer-than-normal weather will be limited to the East and areas along the Gulf Coast.
Meanwhile, below-normal precipitation in portions of the Pacific Coast States, as well as southern sections of Florida and Texas, should contrast with wetter-than-normal conditions in most other areas, especially from the central Plains into the Midwest.
