2011 Super Outbreak
On April 28, the supercells merged into a very large squall line, and moved into Kentucky and the Carolinas. The old squall line of severe thunderstorms moved into Virginia, Maryland, Delaware, New Jersey, and New York. Then later, the new squall line moved into Virginia, Maryland, Delaware, New Jersey, and New York. The storm produced some tornadoes. The other squall lines disappeared. There were five deaths.
