The National Weather Service's Wilmington office confirmed a tornado in Northridge after a preliminary storm survey in the Springfield area today.

There were two confirmed tornadoes amid a flurry of warnings as storms moved through eastern South Dakota during the afternoon and evening of July 28.

A confirmed tornado northwest of Watertown late July 27 caused "significant damage" to a farmstead, a NWS meteorologist told the Argus Leader.

Reports of downed trees and other storm damage came into the NWS office after Thursday's storms moved through parts of Northern Michigan.
