This merged GOES East and West visible image shows the two distinct weather systems predicted to bring snow and other precipitation to much of the U.S. over the weekend. The first system is currently moving on-shore from the Pacific and will likely generate snow throughout the Rockies. The second system is moving up from the Gulf of Mexico across the eastern U.S. While areas south of the Appalachians will see heavy rains, areas north of the mountains may see winter weather over the weekend - with the heaviest snows concentrated around the Ohio River Valley.
