Review of August 24th, 2006 Severe Weather Event

During the late afternoon to early evening hours on Thursday August 24th, portions of South Dakota experienced a severe weather outbreak that is uncommon for late summer. An unseasonably strong upper level trough, sweeping across the northern U.S, influenced the weather across the state.

Most notably, two tornadic supercells moved across the area. The northern tornadic supercell impacted McPherson County, while the southern tornadic supercell impacted Sully, Hyde, and Hand counties.  Below are radar discussions, tornado paths, and damage pictures for the two storms (damage pictures linked from tornado path maps).
