The shelf cloud that passed across Bill Snyder Family Stadium in Manhattan was time-lapsed by Fox Sports photographers as well as various still photographers (see below). The storm contained dangerous lightning and heavy rain.
While the cloud was unusually dramatic, highly visible shelf clouds are not uncommon in Kansas.
Shelf clouds can contain very high winds, but Doppler radar correctly showed the winds with this particular storm were not particularly high. There was only minor wind damage and it was to the east of the stadium.
The game was interrupted for over an hour due to lightning. The Wildcats “won ugly,” 17-13.
UPDATE: Via Jim Reed, we learn the WSJ picture was an Associated Press photograph taken by Charlie Reidel. Thanks, Jim.
