Overview

Scattered thunderstorms which developed along a frontal boundary stretched across portions of northwestern Iowa and southwestern Minnesota produced a wide array of severe weather during the evening of the 23rd of May.

As these storms formed, they were capable of producing very weak landspout tornadoes, one of which briefly touched down near the city of Hospers, IA. However, as they continued to grow, the tornado risk diminished and reports of large hail up to ping pong ball size and damaging winds were received.  Due to the steady northeastward movement of these storms along a front in the area, heavy rainfall was reported in many areas.  By Tuesday morning, rainfall totals were as high as 2 to 4 inches in some locations.
