Rain and snow will diminish over the Intermountain West and Pacific Coast States as a large storm drifts shifts eastward. The storm is expected to stall over the central High Plains, producing heavy snow in the central Rockies, while rain and thunderstorms break- out over the Plains and Corn Belt. In addition, an influx of warm, moist air from the Gulf of Mexico will lead to heavy showers and potentially severe thunderstorms across the Gulf Coast States.
As the storm resumes its eastward trek over the weekend, heavy rain will spread into the Ohio Valley and Mid-Atlantic, while severe weather remains a threat in the Delta and Tennessee Valley.
The 6- to 10-day outlook calls for near- to above-normal precipitation over most of the U.S.
