This Day in National/World Weather History ...
 20 November 1900 → A major tornado outbreak struck Tennessee, Alabama, Mississippi, and Arkansas, including two F4s. In Tunica County, MS an F4 tornado killed 15 people and threw the bodies half a mile downstream. Another F4 tornado was heading right for the center of Columbia, TN, but turned to the north at the last minute and grazed the northwest side of town. Still, 27 people lost their lives homes were "turned into kindling wood." Unpicked cotton was stripped from the stalks and deposited upon trees making them appear to be covered with snow.
 20 November 1944 → "Darkness at Noon." After a decade of drought, dust storms frequented Australia. On this day a thick dust blanketed Mildura for eight hours, and the railway lines to Balranald and Moulamein were blocked by sand.
 20 November 1979 → A blizzard struck Cheyenne, WY producing a record 19.8 inches of snow in 24 hours, and a record total of 25.6 inches in 40 hours. Strong winds created huge drifts stopping all transportation.

                   Weather History...


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 northerly 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 large 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, 1986:

A severe thunderstorm brought extensive damage in Winner in Tripp county. The storm packed 90 mile an hour winds and damaged over 200 houses in Winner. The Tripp County Historical Museum was completely destroyed. Extensive tree damage occurred in town and a plane was flipped over at the airport.

August 6, 1999:

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.
