Lets see, how about....Landicanne?

"One of the strongest storms in the history of the central U.S. affected the region on October 26-27, 2010, producing wind gusts over 50 mph across much of the Midwest, severe thunderstorms and tornadoes from southeast Wisconsin and northeast Illinois to northern Alabama, and a blizzard over northern Minnesota and North Dakota. As the storm reached peak intensity late during the afternoon on October 26 over Minnesota, the lowest barometric pressure readings ever recorded in the central United States occurred. A reading of 28.21" (955.2 mb) was recorded at Bigfork, MN, a pressure that is found in Category 3 hurricanes!"
