Overview

On the afternoon of Tuesday, June13th, a warm and very humid airmass had set up across eastern South Dakota and western Minnesota in advance of a cold front. During the mid afternoon hours storms rapidly developed over central and eastern South Dakota, between Pierre and Aberdeen. These storms quickly strengthened and produced large hail, damaging winds, and eventually tornadoes across the region. The storms evolved into mainly a wind and tornado event around 7pm CDT. Widespread wind damage occurred across northeastern South Dakota and into west central MN as the storms formed a line and moved northeast. Storms quickly exited through Traverse and Big Stone Counties by 10 pm CDT. Several tornadoes were reported to have briefly touched down, causing EF-0 and EF-1 damage.
