August 6th

Local and Regional Events:

August 6, 1962:

Wind damaged farm buildings and hail damaged crops over a large area. The area affected was northern Faulk, portions of Spink, Northern Clark, Codington, and Grant, along with Day County.

 

August 6, 1969:

During the day and evening hours, two relatively large storms brought destructive weather to much of Minnesota. The northern storm area moved in from North Dakota between Fargo and Grand Forks. The southern storm rapidly developed north of Wedena. These two storms combined to cause twelve tornadoes, two vast areas of wind and hail damage, and one waterspout.  The storms killed 15 people, injured 106, and caused 4.8 million dollars in property and public utility damage.

 

August 6, 1969:

The first report of high winds was southeast of Piedmont with gusts of 65 to 70 mph estimated by a National Weather Service employee. Damage in that area included several downed trees and leveled gardens. As the storm moved east, large hail was reported. The first wind gust at Ellsworth AFB was 89 mph at 1918 MST on the northwest end of the runway. By 1925 MST, sustained winds were over 50 mph for nearly 10 minutes, and the peak gust was 114 mph. The sensor on the southeast end of the runway, 2.5 miles away, recorded a wind gust of 114 mph at 1929 MST. The damage on the base included several large trees blown over and snapped in half and roof damage to base housing units. A few tents set up on the taxiways for an air show were blown around, but not significantly damaged. A survey by base meteorologists indicated the main downburst winds hit over open prairie surrounding the runway, where there are no trees or structures. Also between 1920 and 1930 MST, a meteorology student estimated winds between 70 and 80 mph at Box Elder, where gardens were leveled, and wooden fences and roofs were damaged.
