Midwest bracing for another big winter storm

(CNN/WSYR-TV) - Another massive winter storm is barreling through the upper Midwest and making its way to Washington, DC.

Several states are under winter weather advisories or warnings.

The storm is gearing up and dumping tons of snow from the Dakotas to the east coast.

A foot of snow fell on parts of North Dakota.

Minnesota is seeing round two of a one-two punch and some areas in that state could also get a foot of snow.

The storm is causing problems for air travelers as hundreds of flights have been canceled for Tuesday.
