The nation’s main weather event on Wednesday will be a snowstorm system spinning over the Upper Midwest and the Great Lakes regions, according to The Associated Press (AP).

Several inches of snow were expected over the Northern Plains, undoubtedly complicating efforts there to battle widespread flooding in the region.

USA Today reported continued evacuations today along the swelling Missouri River. Ice jams and new snowfall have reportedly complicated flooding conditions, especially in the Bismarck, N.D., area.

Earlier flooding concerns continue to affect cities along the Red River, including Fargo, N.D., and Moorhead, Minn., where volunteers race to build dikes between the river and low-lying dwellings.

President Barack Obama has deemed North Dakota a federal disaster area.

Meanwhile, people in Wyoming and parts of South Dakota and Nebraska continue to dig themselves out of blizzard conditions complicated by several inches of snow and widespread high winds. The National Weather Service (NWS) reported snowfall totals generally ranging from 5 inches (in.) to 15 in. — but nearly 2 feet of snow in the northern Black Hills.

In other weather news, the cold front associated with the Northern Plains storm system will extend from the storm down to the Southern Plains, AP reports, and a line of showers and thunderstorms will extend from the Upper Midwest, down across the Mississippi Valley and into Texas.

Parts of the mid-Atlantic states and the Southeast can expect the line of precipitation to reach the area by the end of the day, according to AP.

Areas of heavy rain and gusty winds associated with the front are anticipated from the Upper Midwest out to the mid-Atlantic, while hail, damaging winds and possibly a tornado will develop across the mid- and lower-Mississippi Valley and the Southeast.

Areas of the Central and Southern Plains behind the front can expect partly to mostly clear skies for the first part of the day before clouds filter in.

Farther east, lingering high pressure will keep skies mostly clear over New England, while most of the Southeast will see clouds and precipitation by the end of the day.

Out West, a second storm system will produce wet weather over the Northwest and down into the Rockies in the Southwest. Areas of heavy snow are expected across the region, and several inches of snow accumulation are expected, according to AP.
