Ranking method · evidence weighted

How the ranking works.

Overview's storm severity score weighs peak radar-indicated hail size, mapped homes inside the footprint, and ground reports filed with the National Weather Service. The score orders storm records inside the cities Overview tracks; it is not a damage finding or a ranking of every city in the United States.
