Radar:

A small area of rotation over the Bluffton, IA area that produced a brief tornado.	Multiple circulations evident on radar near Decorah, one of which produced a TDS just north of town (small circular yellow area in right panel).	Tight velocity couplet on radar north of Waukon (left panel) along with a tornadic debris signature (blue area on right panel) associated with the tornado.	The TDS north of Waukon extended well up through the depth of the storm as seen in multiple tilts on the radar. The TDS reached a maximum height of around 10,000 ft AGL.
