An isolated low-precipitation supercell formed near Allen, South Dakota, producing a long-lived, nearly stationary tornado in some open fields.
Due to the visibility and relatively flat region the tornado formed in, it could reportedly be seen dozens of miles away.
There was some damage to farms, trees, and crops and several deer were killed.
The tornado was rated EF1.
This unusual tornado has been described as a "hybrid" between a landspout and a typical supercell-spawned tornado.
