"The central U.S. was hit Tuesday with a massive storm with wind gusts up to 81 mph. The storm snapped trees and power lines, ripped off roofs, delayed flights and soaked commuters hunched under crumpled umbrellas.
The storm spanned from the Dakotas to the eastern Great Lakes. The unusual system had barometric pressure similar to a Category 3 hurricane, but with much less destructive power.
The National Oceanic and Atmospheric Administration said the system's pressure reading was among the lowest ever in a non-tropical storm in the mainland U.S."
