Southeastern South Dakota saw temperatures swing by more than 125 degrees this year, as colder winters with blizzards were separated by a summer of intense heat and derechos.
The National Weather Service placed Mitchell, as well as areas to the north and east, at moderate risk of severe storms, the fourth highest of five risk categories.
While meteorologists say a second derecho this summer can't be ruled out, it's unlikely another one would strike in the magnitude as last Thursday's storm.
After receiving a report of a tornado on the ground from a member of the public northwest of Freeman, the National Weather Service in Sioux Falls issued a tornado warning. Now, they say no tornado likely produced.
