June 6, 1895:

An estimated F2 tornado moved northeast from 6 miles west of Summit, passing 3 miles northwest of Summit. Buildings were damaged on eight farms.

June 6, 1897:

Light to heavy frost, and in some localities, killing frost occurred on the 6th and 7th. These cold temperatures along with last season frost in May and wet conditions several hampered the planting season. Luckily growing conditions changed towards the middle and end of the month. Some low temperatures on the 6th include; 26 degrees in Castlewood and Watertown, 29 in Mellette, 30 in Aberdeen and Milbank, and 32 in Highmore. Some low temperatures on the 7th include; 24 degrees in Castlewood, 25 in Watertown, and 30 degrees in Milbank.

June 6, 1995:

Slow moving thunderstorms produced very heavy rains in southern Jones County from the late afternoon into the early evening. Some rainfall amounts included; 2.70, 7 miles WSW Murdo and 3.85 inches 2.5 NW Okaton. Several roads were flooded with some roadbeds washed out. Also, a culvert was torn out by the flash flooding.

June 6, 1999:

Heavy rains of 2 to 4 inches caused flash flooding on a creek feeding into the Grand River. At a ranch southwest of Bullhead, a bunkhouse wall moved off the foundation by a wall of water coming down the creek. All of the contents in the bunkhouse were destroyed. A machine shop was washed away along with several pieces of equipment and many tools. Some tools and equipment were found more than a mile down the creek. A pump-house and grain bin was also destroyed. A pickup was washed down the creek and a propane tank near a house was rolled over. A colt was picked up by the water but managed to escape. The powerful flow of water took out several dead trees and washed them down stream. Finally, a road and a culvert were washed out by the flash flood.
