Midwest "Hurricane"

It may look like someone misplaced a hurricane, but this image from a NASA weather satellite actually shows what's known as an extratropical cyclone over North America on October 26. These types of storms tend to form over the United States in spring and fall, when there are a large temperature differences between north and south.
This particular storm—dubbed the Chiclone in the Chicago area—swept across the Midwest last week, setting a record over Minnesota for the lowest pressure (not associated with a hurricane) measured over land in the continental United States. The storm also spawned hail, lighting, and heavy snow as well as 61 reported tornadoes and winds as fast as 78 miles (125 kilometers) an hour in Michigan.
